Top 10 Prediction Market Platforms in 2026, Ranked by Volume

The top prediction market platforms in 2026 are Kalshi, Polymarket, DraftKings Predictions, Novig, Underdog, Robinhood, Predict.fun, ProphetX, Hyperliquid and Gemini, ranked by sourced trading volume for the 30 days to 24 October 2026. Kalshi is the world's biggest prediction exchange by a wide margin, with $87.6 billion of contracts traded in that period, about 76% of the $116 billion tracked across regulated venues, and Polymarket is second at $18.1 billion once its US and international exchanges are combined. The right pick depends on where you live, whether you want a CFTC-regulated app or a crypto wallet, and how much you trade.

Want to earn by predicting what happens next in the world? That is exactly what prediction market platforms let you do. You pick an outcome, you buy a contract on it, and if you are right, each contract pays $1. If you are wrong, you lose what you paid. Simple, but not risk-free.

The space has changed fast. A year ago, crypto platforms dominated the conversation. Today, most of the money flows through federally regulated US exchanges, while crypto-native platforms compete on access, speed and open data. This guide ranks the top prediction market platforms by current, sourced trading data, gives a full list of prediction markets by type and country, explains the software that runs them, shows what each one costs you to trade, and ends with how to build your own.

Key Takeaways

• Kalshi is the world's biggest prediction exchange: it traded $87.6 billion of contracts in the 30 days to 24 October 2026, 76% of all tracked volume and up 60% on the prior 30 days, according to DeFi Rate's volume tracker.
• Prediction markets traded $116 billion in a month: the nine regulated venues DeFi Rate tracks handled $116.0 billion in the 30 days to 24 October 2026, up from $79.6 billion in September.
• Polymarket is now two platforms: a CFTC-regulated US exchange ($13.5 billion, up 94% in 30 days) and a crypto-native international exchange on Polygon ($4.6 billion).
• New entrants reshaped the top 10: Hyperliquid's on-chain outcome markets, the BNB Chain platform Predict.fun and the Gemini exchange all joined the ranking in 2026, while Limitless and Myriad fell out on volume.
• Fees are small but not zero: Kalshi, Polymarket US and Polymarket all price taker fees on a p × (1 – p) curve, so 100 contracts at 50¢ cost $1.74 to $1.75 on the regulated venues and $0 to $1.25 on Polymarket's international exchange.
• Legal status is still moving: federal appeals courts split in 2026 over whether states can regulate sports contracts, India bans money-based prediction apps outright, and the UK has not licensed Polymarket, so check availability where you live before you deposit.

What Is a Prediction Market and Why Are Prediction Market Platforms Growing in 2026?

A prediction market platform is a digital exchange where people buy and sell contracts on future events. Think of it like a stock market, but instead of buying shares in a company, you are buying shares in an outcome.

Prediction market example:

"Will Bitcoin hit $150,000 by December 2026?" You believe it will. You buy a "Yes" contract for $0.60. If Bitcoin hits that price, your contract pays out $1.00. You earn $0.40 profit, before fees. If it does not, your $0.60 is gone.

The price also works as a forecast. A Yes contract trading at 60¢ means the market, as a whole, puts the odds at roughly 60%.

Not every platform runs on a blockchain. Kalshi, Robinhood and the sportsbook exchanges are regulated US exchanges that settle in dollars. Crypto platforms such as Polymarket's international exchange, Hyperliquid, Predict.fun, Limitless and Myriad settle on-chain. On those crypto platforms:

• Your funds sit in a wallet you control, not a bank account
• Smart contracts pay winners automatically when a market resolves
• Anyone in a permitted country can join with a wallet
• Every trade is recorded on a public blockchain

The Growth Is Real, and Here Is the Data

A few years ago, prediction markets were a niche topic. That has changed, and the numbers show it:

• Record quarter: prediction markets traded $113.8 billion of contracts in Q2 2026, up 48.7% on Q1, according to CoinGecko's 2026 Q2 Crypto Industry Report.
• Faster still in the autumn: tracked venues traded $79.6 billion in September 2026, then $116.0 billion in the 30 days to 24 October 2026, per DeFi Rate's aggregated data as of 25 October 2026.
• Mainstream brokers are earning from it: Robinhood booked $156 million of event contract revenue in Q2 2026, more than its crypto or equities revenue, as The Block reported.

Big events drive big action. Elections, sports championships, central bank decisions and tech launches all create new markets. Sports now dominate: on both Kalshi and Polymarket, sports contracts outtrade crypto contracts several times over.

Businesses see real value. Companies and analysts watch market prices as a live, money-backed forecast of what will happen next, and some run internal markets to test ideas.

Regulation pulled in big players. After the CFTC withdrew its 2024 plan to ban political and sports contracts and published a proposed rule on event contracts in June 2026, sportsbooks, brokers and exchanges raced to get licensed.

Now that you understand why prediction markets are growing so fast, the next question is simple: how do you find the best prediction market platform for you? We used a clear, data-first approach.

How We Ranked the Top Prediction Market Platforms by Volume

We did not just pick the most popular names. We ranked each platform on data you can check yourself, then scored the things that matter once you start trading.

Evaluation Method and Data Sources

We looked at:

• Trading volume from DeFi Rate's prediction market tracker, which covers nine regulated venues, using the 30 days to 24 October 2026
• On-chain volume from DefiLlama, which tracks 53 prediction market protocols (41 active in the last 30 days) plus 14 trading interfaces, used for the crypto-native platforms
• Quarterly market share from CoinGecko's Q2 2026 report
• Company filings and earnings, such as Robinhood's Q2 2026 results
• Regulator records, such as CFTC orders designating each exchange
• Each platform's own fee documentation

Platforms are ranked by 30-day volume. Where a platform appears in both trackers we use the DeFi Rate face-value figure, and we say so when a figure comes from DefiLlama instead.

Volume vs Dollars Paid: Read the Numbers Correctly

Here is something most "best platform" lists get wrong. Prediction market volume is usually counted at each contract's $1 face value. A contract bought at 10¢ still counts as $1 of volume.

That makes headline numbers look bigger than the money that actually changed hands. In the 30 days to 24 October 2026, Kalshi traded $87.6 billion of contracts at face value, but traders paid $19.8 billion for them, according to DeFi Rate's Kalshi data. DefiLlama, which measures the dollars traded, shows Kalshi at $15.4 billion for its own 30-day window. Face value shows market activity; dollars paid shows real money at risk. When you compare platforms, make sure both figures use the same measure.

Liquidity and Market Depth

Liquidity means how easy it is to buy or sell a position.

A platform with high liquidity has lots of buyers and sellers. You can enter and exit trades quickly, your order fills fast, and the price does not jump when you trade. Low liquidity means the opposite. You might get stuck in a position, or pay a bad price.

We ranked platforms higher when they had:

• Large trading volumes (well over $1 million a day)
• Many active markets at any given time
• Tight spreads between buy and sell prices

Fee Structure and Cost Transparency

We checked every platform's fee breakdown. This includes:

• Trading fees (what you pay per trade)
• Withdrawal fees (what you pay to move money out)
• Gas fees on blockchain platforms (the small cost to process transactions)

The best platforms publish their fee formula. We worked through real examples in the fee section below, so you can see what a trade actually costs.

Security, Compliance, and Reliability

This one matters most. Before putting money into any platform, you need to know it is safe. We checked:

• Regulatory status: Is the exchange designated by the CFTC, or is it an offshore or crypto-native venue? This decides who can use it and what protections apply.
• Smart contract audits: For crypto platforms, has a trusted third party reviewed the code, and are the reports public?
• Track record: Has the platform ever been hacked? How did it respond?
• Uptime: Does the platform stay online during big events? A platform that crashes on election night is useless.

User Experience and Innovation

A great platform should feel easy to use, even if you are new. We scored each platform on:

• How fast it is to sign up and start trading
• How clear the interface is
• Whether a mobile app is available
• How well the platform explains markets to new users

We also looked at innovation: new market types, parlays and combos, perpetual futures, and better tools for tracking your positions.

Unique Features

Every top platform has something that makes it stand out:

• Combos and parlays: several regulated exchanges now let you combine several outcomes into one contract.
• Embedded markets: some crypto platforms put markets directly inside news articles or wallets.
• Real-time odds that update as new information arrives, just like live sports betting.

We highlighted each platform's best unique feature so you can find the one that fits how you trade.

What Is the World's Biggest Prediction Exchange?

Kalshi is the world's biggest prediction exchange in 2026 on every measure that is public. It traded $87.6 billion of contracts in the 30 days to 24 October 2026, 76% of the volume DeFi Rate tracks across nine regulated venues, and traders paid $19.8 billion for those contracts. On DefiLlama's dollars-traded measure, Kalshi has passed $95 billion of all-time volume. CoinGecko put its share of the whole market at 58.9% in Q2 2026, ahead of Polymarket's 30.2%, and the gap widened in the autumn as sportsbooks and brokers routed flow to it.

Polymarket is the biggest crypto-native prediction exchange and the second-largest overall: $13.5 billion on Polymarket US and $4.6 billion on its international Polygon exchange in the same 30 days, $18.1 billion combined. Nobody else is close. The third-placed venue, DraftKings Predictions, traded $3.7 billion.

Top 10 Prediction Market Platforms You Should Know in 2026

Not all prediction market platforms are the same. Some are federally regulated US exchanges. Some are sportsbooks that became exchanges. Others run on the blockchain. Here are the top 10 prediction market platforms by volume in 2026, ranked by the data above.

DeFi Rate figures are contract face value; DefiLlama figures are dollars traded, so Predict.fun and Hyperliquid would rank the same or higher on a like-for-like basis. Limitless, Myriad, Fanatics Markets, FanDuel Predicts and Manifold follow the top 10 below.

1. Kalshi

Kalshi is a US prediction market exchange regulated by the Commodity Futures Trading Commission (CFTC), where you trade Yes or No contracts on real-world events.

Best For: Traders who want a regulated, US-dollar platform with the widest range of event categories

Volume: $87.6 billion in the 30 days to 24 October 2026, up 60% on the prior 30 days, per DeFi Rate

Markets Available: Sports, politics, economics, finance, weather, culture, technology, crypto and international affairs, plus combos and newer perpetual futures on commodities

Offers:

• CFTC-regulated event contracts that pay $1 per winning contract
• Yes/No trading through an order book, with mobile and desktop apps
• A published fee formula based on each contract's expected earnings
• Distribution through brokers such as Robinhood, Coinbase and Webull, which route customer orders to Kalshi

Why Choose Kalshi?

The CFTC designated KalshiEX LLC as a contract market in November 2020, and its affiliate Kalshi Klear is a CFTC-registered clearing house. That makes it one of the most established regulated venues for event trading in the US.

Here is why people choose it:

• It is regulated. Kalshi operates under federal oversight as a designated contract market, with KYC and surveillance like any futures exchange.
• It is easy to understand. Every market is a Yes or No question. You pick a side, buy contracts, and each winning contract pays $1. No complicated mechanics.
• It is strong on economics. Want to trade on whether inflation rises, whether the Fed cuts rates, or what the next jobs report shows? Kalshi lists all of these in detail.
• It has the deepest sports book. Sports make up the largest share of Kalshi's activity, and combo contracts now account for a large part of its volume.
• It powers other apps. Coinbase's prediction markets went live in all 50 states on 28 January 2026 with contracts and liquidity supplied by Kalshi.

Watch out for: state challenges. In August 2026 the Ninth Circuit let Nevada enforce its gaming laws against Kalshi's sports contracts, and in September 2026 the Sixth Circuit reached a similar result in an Ohio case, while the Third Circuit sided with Kalshi in April 2026. Sports availability can differ by state.

If you are in the US and want a regulated platform with a wide range of markets, Kalshi is the benchmark. Want to build something like that? Start here: how to create a prediction market platform like Kalshi.

2. Polymarket

Polymarket is the world's best-known crypto prediction market. It now runs two exchanges: an international platform on the Polygon blockchain and a separate CFTC-regulated US exchange, Polymarket US.

Best For: Crypto-native traders who want a huge market list, open data and fast settlement

Volume: $13.5 billion on Polymarket US (up 94%) and $4.6 billion on the international exchange in the 30 days to 24 October 2026, per DeFi Rate

Markets Available: Politics, sports, crypto, finance, technology, culture, geopolitics and more, with thousands of active markets

Offers:

• Trading in pUSD, a USDC-backed collateral token on Polygon (international exchange)
• A central limit order book with real-time odds
• Public APIs, SDKs and WebSocket feeds for developers
• Perpetual futures on the international platform, launched in 2026

Why Choose Polymarket?

Polymarket has the largest crypto-native prediction market, and its design shows why traders trust it.

It is transparent. Orders are matched off-chain by an operator and settled on-chain through smart contracts, so you keep custody of your funds until a trade settles. Polymarket calls this a "hybrid-decentralized" order book.

Resolution is open. Most markets resolve through the UMA Optimistic Oracle: anyone can propose an outcome by posting a bond, and anyone can dispute it within a two-hour window. Undisputed markets resolve in about two hours.

It covers almost everything. Want to trade on who wins the next election, what price Bitcoin hits next month, or whether a tech company ships a product? Polymarket lists markets on nearly every major event.

It is back in the US, and growing fastest there. Polymarket bought QCEX, whose exchange the CFTC designated as a contract market in July 2025. Polymarket US opened to iOS users in May 2026, as Yogonet reported, and its 30-day volume almost doubled between September and October 2026.

If you want the biggest crypto-native markets and a platform with open on-chain data, Polymarket is your first stop.

Thinking about building something similar? Here is where to start: how to create a prediction market platform like Polymarket.

3. DraftKings Predictions

DraftKings Predictions is the prediction market app from DraftKings, the US sportsbook and fantasy sports company.

Best For: Sports fans who already have a DraftKings account

Volume: $3.7 billion in the 30 days to 24 October 2026, up 147% on the prior 30 days, per DeFi Rate

Why Choose DraftKings Predictions?

• Its own exchange. DraftKings bought Railbird, a CFTC-designated exchange, in October 2025, and launched its in-house DKeX exchange in June 2026.
• Sports depth. Contracts on game results and player performance feel familiar to anyone who uses a sportsbook.
• Fast growth. It was one of the fastest-growing venues in the tracker over the last 30 days, and the largest after Kalshi and Polymarket.

4. Novig

Novig is a sports-focused, peer-to-peer prediction market exchange where users trade against each other instead of against a bookmaker.

Best For: Sports traders who want exchange-style pricing

Volume: $2.8 billion in the 30 days to 24 October 2026, up 132%

Why Choose Novig?

• Federally designated. The CFTC designated Novig's exchange, Ludlow Exchange, as a contract market in June 2026, as CNBC reported.
• Peer-to-peer pricing. You trade with other users, so prices are set by the market, not by a house edge.
• Stricter age rule. Novig limits event contract trading to users aged 21 and older.

5. Underdog

Underdog is a US fantasy sports company that now runs its own CFTC-regulated prediction market exchange, UDX.

Best For: Fantasy sports players who want to trade on games and player stats

Volume: $1.5 billion in the 30 days to 23 October 2026, up 149%

Why Choose Underdog?

• Full licence stack. Underdog bought Aristotle Exchange, gaining both an exchange (DCM) and a clearing house (DCO), and launched prediction markets on its own exchange in July 2026.
• Familiar product. Contracts on baseball, basketball and other sports sit inside an app fantasy players already know.

6. Robinhood

Robinhood is a US brokerage app whose Prediction Markets Hub lets customers trade event contracts next to stocks, options and crypto.

Best For: US beginners who already use Robinhood and want to start without opening a new account

Scale: $1.2 billion traded on Rothera, its own exchange, in the 30 days to 23 October 2026, plus $156 million of event contract revenue in Q2 2026, more than ten times a year earlier

Markets Available: Sports, politics, economics, crypto, culture, weather and more

Why Choose Robinhood?

Robinhood is already trusted by millions of Americans for stock trading. Prediction markets became one of its fastest-growing product lines in 2026.

• No new account needed. If you already use Robinhood, you can trade predictions inside the same app. No crypto wallet, no new sign-up.
• Easy to use. Each contract shows the odds and your cost before you confirm.
• Regulated routing. Robinhood offers contracts through Robinhood Derivatives, LLC and routes orders to regulated exchanges, including Kalshi, ForecastEx and Rothera, its own exchange with Susquehanna. The joint venture bought the CFTC-licensed MIAXdx exchange, and Rothera launched in June 2026.

Because much of Robinhood's flow is still executed on Kalshi, part of its activity shows up inside Kalshi's volume. That is why we rank Robinhood on Rothera's volume and its own revenue rather than a single headline figure.

For US users who want the easiest way into prediction markets, Robinhood is hard to beat.

7. Predict.fun

Predict.fun is a BNB Chain prediction market that pays DeFi lending yield on the collateral behind open positions, so capital is never idle while a market runs.

Best For: Crypto traders on BNB Chain, and Trust Wallet users, who want yield while they wait for a market to resolve

Volume: $380 million traded in the 30 days to 25 October 2026 and $3.6 billion all-time, per DefiLlama

Why Choose Predict.fun?

• Backed by Binance's founders' investment arm. The platform launched in December 2025 with YZi Labs as an investor, and is distributed inside Trust Wallet's Predictions tab.
• Yield on open positions. Deposited stablecoins are routed through lending protocols, so a position earns while it is open.
• Fast growth. It is the largest crypto-native prediction market after Polymarket on DefiLlama's dollars-traded measure.

8. ProphetX

ProphetX is a sports-only prediction market exchange that both lists and clears its own contracts.

Best For: Traders who only want sports markets

Volume: $296 million in the 30 days to 24 October 2026, up 35%

Why Choose ProphetX?

• Direct clearing. The CFTC approved ProphetX as a designated contract market on 11 June 2026, and it also holds clearing approval, so it executes and settles trades on one platform.
• Pure sports focus. No politics or culture markets, just sports.

9. Hyperliquid Outcome Markets

Hyperliquid, the largest on-chain perpetuals exchange, added prediction markets to its own chain in 2026 through HIP-4, which it calls outcome markets.

Best For: Perpetuals traders who want event markets in the same account, outside the US

Volume: $56.4 million traded in the 30 days to 25 October 2026 and $279 million since launch, per DefiLlama

Why Choose Hyperliquid?

• Live since May 2026. Hyperliquid launched prediction markets on offchain events in May 2026, starting with CPI and Federal Reserve rate markets, after a testnet phase in February.
• Validator-run resolution. Under HIP-4, validators deploy and settle markets through on-chain governance instead of an external oracle, which is faster but concentrates control in the validator set.
• Fees only on exit. Opening a position is free; fees apply when a position is closed or settled, and DefiLlama notes that Hyperliquid charged no outcome fee of its own before 15 August 2026, with 99% of fees since then going to the Assistance Fund that buys back HYPE.
• US users are restricted. Like Hyperliquid's perps, outcome markets are not offered to US residents.

10. Gemini

Gemini is a US crypto exchange whose subsidiary Gemini Titan runs a CFTC-designated contract market for event contracts.

Best For: Gemini customers who want simple Yes or No contracts next to their crypto holdings

Volume: $41 million in the 30 days to 24 October 2026, per DeFi Rate

Why Choose Gemini?

• Licensed exchange. Gemini Titan received its designated contract market licence from the CFTC on 10 December 2025, five years after first applying.
• Crypto-first markets. Gemini positions its contracts for crypto event trading and has agreed in principle to supply crypto event contracts to brokerage customers through Apex Fintech.
• Small but tracked. It is the smallest venue in DeFi Rate's tracker, so liquidity is thinner than on Kalshi or Polymarket.

Platforms 11 to 15: Limitless, Myriad, Fanatics Markets, FanDuel Predicts and Manifold

Limitless is a crypto-native prediction market on Base, Coinbase's Ethereum layer 2, best known for short-dated crypto price markets. DefiLlama shows $1.47 billion of all-time volume but only $1.5 million in the 30 days to 25 October 2026, far below the roughly $2 billion a month that Bernstein estimated in January 2026, so check live data before you trade. Takers pay 0.40% to 3.00% depending on price and makers pay nothing, per DefiLlama's methodology notes. It has not launched for US customers.

Myriad embeds prediction markets inside news articles and media, and uses an automated market maker so there is always a price. DefiLlama tracks $235 million of all-time volume on Abstract, Linea and BNB Chain but only about $0.6 million in the last 30 days; Decrypt stated more than $600 million cumulative when it announced The Information Exchange on Solana on 30 September 2026, so most current activity appears to be moving to Solana.

Fanatics Markets launched on 3 December 2025 as the first sportsbook-branded event contract app, with markets and pricing supplied by Crypto.com's CFTC-registered exchange, Crypto.com Derivatives North America. It does not publish volume and is not in the public trackers.

FanDuel Predicts is the FanDuel and CME Group venture, which launched in five states in December 2025. Volume has stayed small compared with DraftKings Predictions.

Manifold is a play-money prediction market where anyone can create and trade markets using a virtual currency called Mana. It does not use real money, and Mana cannot be withdrawn as cash. That makes it the best starting point for beginners, researchers and anyone who wants to practise without risk: you can read how Manifold works and start in a minute.

What Changed Since Our Last Update

• Three new entrants in the top 10: Predict.fun, Hyperliquid's outcome markets and Gemini replaced Limitless, Myriad and Manifold, which now sit in the 11 to 15 group on volume.
• Kalshi's lead widened: from $60.7 billion in September to $87.6 billion in the latest 30 days, and total tracked volume rose from $79.6 billion to $116.0 billion.
• Polymarket US almost doubled to $13.5 billion while the international exchange slipped 5% to $4.6 billion.
• Drift Protocol (BET): Drift, a Solana trading protocol, lost about $285 million in an exploit on 1 April 2026 and planned a relaunch as a leaner, perpetuals-focused exchange, as Decrypt reported. We found no current data on its BET prediction market.
• Hedgehog Markets: we could not find current, public volume or user figures, so we cannot rank it against platforms that publish data.

List of Prediction Markets in 2026: Every Platform by Type

Searchers asking for a list of prediction markets usually want more than the top 10. Here is the full list of prediction market sites and apps we could verify in October 2026, grouped by type.

How Many Prediction Market Platforms Are There?

More than most people expect, but the money is concentrated. DeFi Rate tracks nine regulated venues, and DefiLlama lists 53 prediction market protocols, 41 of them active in the last 30 days, plus 14 interfaces such as wallet and exchange front-ends that route trades to those protocols. Across all 53, DefiLlama counted about $22 billion of dollars traded in 30 days, and Kalshi alone accounted for roughly 70% of it. So there are 50 to 60 live platforms worldwide, but two of them, Kalshi and Polymarket, handle the large majority of trading.

Prediction Market Platforms by Country: USA, UK, India and UAE

Where you live decides which prediction market platforms you can use.

Prediction Market Platforms in the USA

US residents have the widest choice: Kalshi, Polymarket US, Robinhood, Coinbase, DraftKings Predictions, Novig, Underdog, ProphetX, Gemini, Fanatics Markets and FanDuel Predicts all operate under CFTC designation. The open question is state law for sports contracts, where the Third Circuit sided with Kalshi while the Ninth and Sixth Circuits let Nevada and Ohio apply gaming laws, so sports markets can be unavailable in some states. Crypto-native platforms such as Polymarket's international exchange, Hyperliquid and Limitless block US users.

Prediction Market Platforms in the UK

The UK has no licensed prediction market exchange in the US sense. Polymarket remains geoblocked and holds no Gambling Commission licence; in September 2026 it was reported to be meeting UK and European regulators and lobbying to be treated as a financial service rather than a gambling operator. UK residents who want exchange-style trading on sports and politics use licensed betting exchanges such as Betfair Exchange and Smarkets, which are regulated as gambling.

Prediction Market Platforms in India

India banned prediction markets that involve money. The Promotion and Regulation of Online Gaming Act, 2025 prohibits all online money games, and opinion-trading platforms were among the first to go: Probo shut its Indian operations in August 2025 as the Bill passed. Any prediction market platform for India must therefore be free to play or aimed at users outside India.

Prediction Market Platforms in the UAE

Neither the UAE's federal gaming regulator, the GCGRA, nor Dubai's VARA has issued rules specific to prediction markets, so take local legal advice before trading or launching one from the UAE.

Comparison Table of Top Prediction Market Platforms

Choosing the right platform is easier when you can see everything side by side.

What a Trade Actually Costs: Kalshi vs Polymarket

Most platform lists say fees are "low". Here is the maths, so you can see for yourself.

Kalshi and both Polymarket exchanges charge takers a fee that follows the same shape: fee = rate × contracts × price × (1 – price). The fee is highest when a contract trades near 50¢ and falls toward zero near 1¢ or 99¢.

• Kalshi: the standard taker rate is 0.07, rounded up to the next cent. Some markets also carry maker fees. Kalshi explains that it charges a fee on the contract's expected earnings.
• Polymarket US: the taker rate has been 0.0695 since 16 September 2026, after rising from a flat 1% in early 2026 to 0.05 in April and 0.06 in July, according to the fee schedule recorded in DefiLlama's Polymarket US methodology.
• Polymarket (international): the rate depends on the category: 0.07 for crypto, 0.05 for sports, 0.04 for politics, and 0 for geopolitics. Makers are never charged.

Worked example: buying 100 contracts as a taker

Two lessons follow. First, a $1.75 fee on a $50 trade is 3.5%, which matters if you trade often. Second, placing a limit order that rests on the book (becoming a maker) can cut your costs to zero on Polymarket and lower them on many Kalshi markets.

How to Choose the Right Prediction Market Platform

Even among the top prediction market platforms, there is no single best choice. The right one depends on your goals, your location and how comfortable you are with crypto. Here is a simple, step-by-step guide.

Identify Your Use Case

Start with your purpose. Are you trading, learning or exploring? Sports fans will feel at home on DraftKings, Underdog, Novig or ProphetX. Macro traders will prefer Kalshi's economics markets. Perp traders can stay on Hyperliquid. Beginners can practise on Manifold first.

Regulatory Requirements and KYC Policies

Check whether the platform operates legally where you live, using the country section above. US residents should use CFTC-regulated venues and should check their state, since sports contracts are under legal challenge in several states. Crypto-native platforms block some countries, including the US for most of them.

Evaluate Liquidity and Market Activity

Higher activity means you can buy and sell easily without big price gaps. Use the volume table above as a starting point, and look at the order book depth on the specific market you want to trade.

Compare Fees and Accessibility

Use the fee table above. Also consider deposit methods: bank and card funding on regulated apps, stablecoins on crypto platforms. A simple interface and easy funding make a big difference for beginners.

Assess Security and Platform Credibility

Check the platform's regulator, audit reports and track record. The Drift exploit in April 2026 is a reminder that even well-known crypto protocols can be compromised.

Once you know how to choose the right platform, it is also important to understand how these platforms earn.

How Do Prediction Market Platforms Make Money?

Prediction market exchanges do not bet against you. They are not sportsbooks. They act more like a stock exchange: they earn from running the marketplace, not from whether you win or lose. Here are the main ways they earn:

Transaction and trading fees: A small fee on each trade. Even a low rate generates high revenue at scale: DefiLlama shows Polymarket US collecting $87.0 million and Polymarket's international exchange $31.1 million in taker fees over the 30 days to 25 October 2026, and Robinhood booked $156 million of event contract revenue in a single quarter.

Market creation fees: Organisations may pay to create or feature official markets.

Commissions and spreads: Brokers add a per-contract commission on top of the exchange fee.

Liquidity and token models: Crypto platforms use tokens or rebates to reward active traders and market makers, and Hyperliquid routes its outcome fees into HYPE buybacks.

Yield on collateral: Predict.fun lends out the stablecoins behind open positions and shares the yield, a model borrowed from DeFi.

Premium features: Advanced analytics, charts and data tools offered on subscription.

API and data access: Real-time probability data has value to media, funds and researchers.

Advertising and sponsorships: Brands sponsor markets, and leagues and athletes sign partnership deals with platforms.

Now that you have a clear idea of how these platforms operate and earn, the next step is understanding the software behind them.

Prediction Market Software: What Runs a Platform

Every platform on this list is built from the same five components. Understanding them helps you judge a platform as a trader and scope one as a builder.

1. Matching engine. Kalshi, Polymarket and Hyperliquid use a central limit order book, where buyers and sellers post prices and the engine matches them. Myriad and PancakeSwap Prediction use an automated market maker, which always quotes a price from a formula. Order books give tighter prices with volume; AMMs guarantee liquidity in thin markets.
2. Collateral and settlement. Regulated venues hold dollars at a clearing house (Kalshi Klear, Gemini Olympus, CME). Crypto venues hold stablecoins in smart contracts: pUSD on Polymarket, USDC on Base and Hyperliquid, stablecoins on BNB Chain for Predict.fun. Each winning contract pays $1.
3. Resolution. Someone has to decide what happened. Kalshi resolves in-house against named sources; Polymarket uses UMA's optimistic oracle with a dispute window; Hyperliquid uses its validator set. Resolution design is where most platform disputes start.
4. Compliance layer. KYC, age checks, geolocation and state or country blocking on regulated venues; wallet-based access with country blocks on crypto venues.
5. Interfaces and APIs. Public APIs let brokers (Robinhood, Coinbase), wallets (Trust Wallet, MetaMask) and media sites (Myriad) embed markets, which is how one exchange's liquidity reaches many front-ends.

Prediction market software reaches a new operator in three forms: open-source building blocks such as conditional token contracts and oracle integrations, white-label platforms that bundle the five components under your brand, and custom development when the market mechanism or jurisdiction needs something new. The next section covers that route.

Prediction Markets vs Polls: Why Traders Watch Prices

A poll asks a sample of people what they think will happen or how they will act. A prediction market asks people to put money on it, and the price aggregates every participant's information, updated continuously as news arrives. That is why a Kalshi or Polymarket price is quoted alongside polling averages before elections and ahead of central bank decisions.

The trade-offs matter. Markets react within minutes, while polls take days to field. Markets can be moved by a single large trader or by thin liquidity, which a well-run poll cannot. Markets also need a clear, verifiable resolution, so they work best for events with a definite outcome and a date. For a trader, the practical lesson is that a market price is the crowd's best estimate including the information in the polls, so the edge comes from knowing something the price does not yet reflect.

What's the Best Prediction Market Platform? What Reddit Traders Ask

The r/sportsbetting thread titled "What's the best prediction market platform?" ranks on the first page for this search, and Quora's "What are the biggest prediction markets?" sits just below it. Here are plain answers.

What is the best prediction market platform for someone switching from sportsbooks?

Novig and ProphetX, because both are peer-to-peer sports exchanges with no bookmaker margin, and both are CFTC-designated. DraftKings Predictions and Underdog are the easiest switch if you already hold an account there. Kalshi has the deepest sports liquidity, which matters for larger bets.

What are the biggest prediction markets?

Kalshi ($87.6 billion in 30 days), Polymarket ($18.1 billion across its two exchanges), DraftKings Predictions ($3.7 billion), Novig ($2.8 billion) and Underdog ($1.5 billion), all for the 30 days to 24 October 2026 on DeFi Rate's face-value measure.

Can you make money in prediction markets?

Yes, but it is trading, not a payout machine. You profit when your estimate of an outcome is more accurate than the market price after fees, and you lose the full price of a contract when you are wrong. Taker fees of up to 3.5% of a 50¢ trade mean frequent traders need a real edge, and resting limit orders (becoming a maker) cuts the cost. Treat it like any other market: position size, record keeping and a reason for every trade.

Are prediction markets legal in the US?

Yes on CFTC-designated exchanges such as Kalshi, Polymarket US, Robinhood, Novig, Underdog, ProphetX and Gemini. The dispute is about sports contracts at state level: the Third Circuit backed Kalshi in April 2026, while the Ninth Circuit (Nevada, August 2026) and the Sixth Circuit (Ohio, September 2026) let states apply gaming laws, so sports availability varies by state. Offshore crypto platforms block US users.

What are some sports prediction market apps similar to Kalshi?

Novig, ProphetX, DraftKings Predictions, Underdog, FanDuel Predicts and Fanatics Markets are all CFTC-regulated sports-focused alternatives. Robinhood and Coinbase let you trade Kalshi's own sports contracts inside their apps.

Want to Build Your Own Prediction Market Platform?

Some readers do not want to trade on a platform, they want to own one. That might be a white-label exchange for a regional market, a sports-focused app, or an internal forecasting tool for a company.

Building one well means solving the problems that every platform on this list had to solve:

• Scalable infrastructure that handles traffic spikes during finals and election nights
• Smart contract security, with audits and monitoring for crypto platforms
• Resolution and oracles that settle markets correctly and handle disputes
• Liquidity bootstrapping, so new markets have a fair price from day one
• Compliance that fits the jurisdiction, from KYC to geo-restriction controls

Frequently Asked Questions

What is the biggest prediction market platform in 2026?

Kalshi is the biggest by volume. It traded $87.6 billion of contracts in the 30 days to 24 October 2026, about 76% of all volume tracked by DeFi Rate. Polymarket is second at $18.1 billion when its US and international exchanges are combined.

What is the best prediction app in the world?

By volume and market range, Kalshi. For the easiest start, Robinhood, which puts event contracts next to stocks with no new account. For crypto-native trading outside the US, Polymarket. For risk-free practice, Manifold. The "best" app is the one that is legal where you live and lists the markets you understand.

Is Polymarket legal in the US?

Yes, through Polymarket US. Polymarket bought QCEX, a CFTC-designated exchange, and opened its US app to iOS users in May 2026. The international Polymarket exchange still blocks US users.

Are prediction markets legal in the US?

Yes on CFTC-designated exchanges. The unsettled question is sports contracts under state law, where the Third Circuit sided with Kalshi while the Ninth and Sixth Circuits let Nevada and Ohio apply gaming laws in 2026, so sports markets can be restricted in some states.

Which prediction market is best for beginners?

Robinhood is the easiest for existing Robinhood users, since there is no new account to open. If you want to learn without any risk, start on Manifold, which uses play money.

Can you make money in prediction markets?

Yes, if your forecasts beat the market price after fees, and no, if they do not: a losing contract settles at $0 and you lose what you paid. Fees of up to 3.5% on a 50¢ trade and thin liquidity on small markets eat into returns, so only trade money you can afford to lose.

Are prediction markets gambling?

It depends on who you ask and where you live. The CFTC treats event contracts on designated exchanges as regulated derivatives, but federal appeals courts split in 2026 on sports contracts, the UK regulates exchange-style event trading as gambling, and India bans money-based prediction apps altogether.

How do prediction market platforms make money?

Mostly from trading fees. Kalshi and Polymarket both charge takers a fee that peaks when a contract trades near 50¢, Polymarket's two exchanges collected about $118 million in fees in the 30 days to 25 October 2026, and brokers such as Robinhood add a small commission per contract.

How many prediction market platforms are there?

Roughly 50 to 60 live platforms worldwide. DeFi Rate tracks nine regulated US venues and DefiLlama lists 53 prediction market protocols plus 14 interfaces, but Kalshi and Polymarket handle the large majority of all volume.

Is there a prediction market platform in India?

Not legally for money. India's Promotion and Regulation of Online Gaming Act, 2025 bans all online money games, and opinion-trading apps such as Probo shut down in August 2025. A prediction market platform aimed at India must be free to play, or serve users in other countries.

Final Thoughts

The top prediction market platforms in 2026 look very different from a year ago. Kalshi dominates regulated volume as the world's biggest prediction exchange, Polymarket leads crypto-native trading and has rebuilt its US presence, sportsbooks such as DraftKings, Underdog, Novig and ProphetX run their own exchanges, and Hyperliquid, Predict.fun and Gemini have joined the top 10. Pick the platform that is legal where you live, check the fee maths before you trade, and start small. And if you would rather own the marketplace than trade on it, Pixel Web Solutions can help you plan and build a prediction market platform that fits your market and your rules.
