Sports prediction markets have gone from a niche curiosity to a multi-billion-dollar industry in under two years. The Super Bowl alone generated over $1 billion in prediction market volume on Kalshi in 2026. The NCAA Tournament is the most-traded event on multiple platforms right now. And unlike traditional sportsbooks, prediction markets are federally regulated and available in all 50 states — including states where legal sports betting doesn't exist.
But not all prediction market platforms are equal for sports. Some have deep liquidity and broad sport coverage. Others are still catching up. Fees vary wildly. And the regulatory landscape is changing monthly. We've traded on every major platform and ranked them based on what actually matters for sports traders: market selection, liquidity, fees, execution quality, and user experience.
Quick Comparison: Sports Prediction Markets Ranked
| Rank | Platform | Best for | Sports fee per contract | Sports covered | Parlays | Limit orders | Available states |
|---|---|---|---|---|---|---|---|

How We Ranked These Platforms
Every platform on this list is CFTC-regulated or operates through a CFTC-licensed exchange. We didn't consider unregulated or offshore platforms. Within that field, we evaluated five criteria specific to sports trading: the breadth and depth of sports markets available, the liquidity on game-day contracts, the fee structure for typical sports trades, the quality of execution (order types, speed, live trading), and the overall user experience on mobile.
1. Kalshi — The Sports Prediction Market Leader
Kalshi is the dominant platform for sports prediction trading in 2026. No other platform matches its combination of market breadth, liquidity depth, and trading infrastructure for sports.
Why Kalshi Ranks First
Sports now generates approximately 90% of Kalshi's revenue. The platform processed $22.88 billion in total trading volume in 2025, with sports driving the overwhelming majority. College basketball became the most-traded sport on Kalshi during February 2026 as March Madness approached, after NFL season powered record volumes in the fall.
The sports catalog is comprehensive. Kalshi covers NFL, NBA, NCAAB, NHL, MLB, soccer, tennis, golf, UFC, and esports with game winners, spreads, totals, player props, and futures. The "Build Your Combo" parlay feature lets you combine multiple outcomes into a single position. For anyone coming from traditional sports betting, the contract format feels immediately familiar — the key difference is that you're trading on an exchange rather than against a house.
Kalshi also supports both market orders and limit orders. Limit orders (which Kalshi calls "maker" orders) get lower fees, incentivizing users to add liquidity. This is a significant advantage over platforms that only offer market orders, because limit orders let you set precise entry and exit prices instead of accepting whatever quote is available.
Fees
Kalshi uses a probability-weighted formula where fees scale with contract price. Fees peak near 50/50 contracts and approach zero at extreme probabilities. The maximum is roughly $0.02 per contract. Taker fees are slightly higher than maker fees.
On a practical level: a $100 position at even odds costs roughly $3.50 in taker fees. At $1,000, it's about $35. This is higher than Polymarket or Robinhood but lower than DraftKings or FanDuel at scale.
Key Advantage: Distribution
Kalshi's partnership with Robinhood — which reportedly drives more than half of Kalshi's total volume — gives it distribution that no standalone prediction market can match. Millions of retail investors who already have Robinhood accounts can trade Kalshi's sports contracts without creating a separate account. Kalshi has also partnered with CNN and CNBC for live market data integration, and Google now displays Kalshi odds in search results.
Kalshi also offers a free demo account — the only major prediction market to do so. For sports traders new to the exchange model, this is an excellent way to learn the mechanics risk-free.
What Could Be Better
The mobile app has drawn criticism for occasional freezing, inconsistent price displays, and UI changes that moved useful information off the main screen. Kalshi's team has been responsive to feedback, but app stability remains a work in progress. Fees are also higher than Polymarket for active traders who move in and out of positions frequently.
Bottom Line
If you want the widest sports market selection, deepest liquidity, and most mature trading infrastructure, Kalshi is the clear choice. It's the platform that most closely replicates the sportsbook experience in a prediction market format.
2. Robinhood — The Easiest Way to Start
Robinhood isn't a prediction market — it's a brokerage that integrates prediction market contracts directly into its existing investing app. But for sports trading specifically, that distinction barely matters to the end user.
Why Robinhood Ranks Second
Robinhood's sports prediction markets have become the company's fastest-growing product line by revenue ever, with 11 billion contracts traded by more than 1 million customers since launch. The platform currently lists over 1,600 markets across 17 contract categories, with each sport organized into its own section.
The sports coverage is strong. Robinhood offers NFL, NBA, NCAAB, NHL, MLB, UFC, soccer, and even esports markets. Game outcomes, spreads, totals, and player props (touchdowns, passing yards, rebounds, assists, etc.) are all available. The platform recently added preset combos (parlay-equivalent for individual games) and custom combos where you can combine up to 10 outcomes into a single contract.
Limit orders are supported, along with dollar-based trading (so you can enter a position by dollar amount rather than contract count). Live sports scores and real-time updates are displayed alongside active contracts.
Fees
Robinhood charges $0.02 per contract total — $0.01 commission plus $0.01 exchange fee. This is a flat structure that's easy to understand and competitive with Kalshi's variable model. On contracts near even odds, Robinhood is slightly cheaper than Kalshi. On extreme probabilities, Kalshi's formula produces lower fees.
No deposit fees for standard bank transfers. A 1.75% fee applies if you want instant withdrawal processing.
Key Advantage: Zero Friction Onboarding
If you already have a Robinhood account — and roughly 27 million people do — you can start trading sports contracts in minutes by applying for a derivatives account. No separate platform, no new app, no new deposit. Your existing balance is immediately available. For someone who has never used a prediction market before, this is by far the lowest-friction entry point.
What Could Be Better
Robinhood currently operates as a broker distributing Kalshi's exchange contracts (though this will change once Robinhood completes its acquisition of LedgerX/MIAX Derivatives Exchange). This means liquidity is ultimately Kalshi's liquidity. Robinhood also doesn't offer a demo account, and community features are minimal — there's no equivalent of Polymarket's per-market comment sections or OG's live chat.
Bottom Line
Robinhood is the best choice for anyone who wants to add sports prediction trading to an existing investment platform without the friction of a new account. The fees are among the lowest, the interface is polished, and the combo feature is well-implemented.
3. OG (Crypto.com) — Best Social Experience for Sports
OG launched in February 2026 as Crypto.com's standalone prediction market platform, and it's clearly built with sports traders in mind.
Why OG Ranks Third
OG's sports coverage is strong, with markets across NFL, NBA, NCAAB, NHL, soccer, tennis, golf, UFC, and Formula 1. Where OG distinguishes itself is in the depth of its player props and the social layer built around sports trading.
The props selection goes deeper than many competitors. For major events, OG posts scoring props, game props, and novelty props that open up trading angles beyond the standard moneyline. The parlay feature lets you combine multiple outcomes into a single position.
But OG's real differentiator for sports is the community. Built-in chat lets users discuss active games in real time, share reads, and react to live events. Leaderboards track performance and add a competitive dimension. For sports traders who want the communal experience of watching a game and trading alongside other people, OG is the closest thing to a sports bar with a trading terminal.
The platform also explicitly states that sharp bettors, VIPs, and analytical traders are welcome — and that winners won't be limited or banned. This directly addresses a pain point from traditional sportsbooks.
Fees
OG charges $0.02 per contract to open and $0.02 to close early. If your contract settles correctly (you win), no fee is charged on settlement. This means winning trades effectively cost half what losing trades cost. It's a transparent, easy-to-understand structure, though it's more expensive than Polymarket or Robinhood for active traders.
What Could Be Better
OG doesn't support limit orders — a significant gap for traders who care about precise execution. You can only trade at whatever market price is currently available. The platform also doesn't display trading volume or order book depth on individual markets, making it harder to gauge liquidity before entering a position. And as the newest major platform (launched February 2026), OG's track record is the shortest.
Bottom Line
OG is the best pick for sports traders who value community, social features, and deep props alongside their trading. The interface is clean, the mobile app is polished, and the no-user-limits policy is appealing. The lack of limit orders holds it back from a higher ranking.
4. Polymarket — Best Fees for Active Sports Traders
Polymarket is the world's largest prediction market by total volume, but its sports offering is still catching up to Kalshi's.
Why Polymarket Ranks Fourth for Sports
Polymarket's sports coverage includes NFL, NBA, NCAAB, NHL, soccer, and esports. The markets are there, and liquidity is growing. But compared to Kalshi's catalog — which includes wider sport selection, deeper props, and more granular markets — Polymarket's sports section is narrower.
Where Polymarket wins for sports traders is on cost. The US platform charges taker fees of just 0.10% (10 basis points), with maker orders earning a 0.10% rebate. For an active sports trader executing $50,000 in monthly volume, the fee savings versus Kalshi or OG are substantial — potentially thousands of dollars per year.
Polymarket also supports limit orders, giving traders precise control over entry and exit prices. The order book model rewards patience and allows you to provide liquidity at your own price rather than accepting whatever's available.
Key Advantage: API and Algorithmic Trading
For sports traders who use bots, algorithms, or quantitative models, Polymarket's API infrastructure is significantly more comprehensive than any competitor. Three separate APIs, WebSocket streaming for real-time data, official SDKs, and active developer documentation make it the platform of choice for systematic sports trading.
What Could Be Better
Polymarket's US platform is still in a phased rollout, so not all users have full access yet. The sports market catalog is narrower than Kalshi's — fewer sports, fewer prop types, no parlay feature. And while the global platform is USDC-based (requiring crypto knowledge), the US platform has simplified onboarding with fiat deposits.
Community features are strong — per-market comments sections and leaderboards — but the sports-specific community is less active than OG's dedicated chat or even Kalshi's growing "Ideas" section.
Bottom Line
If you're an active, fee-sensitive sports trader — especially one who trades algorithmically — Polymarket offers the best cost structure in the industry. For casual sports traders who want the widest market selection and simplest onboarding, Kalshi or Robinhood is a better starting point.
5. DraftKings Predictions — For the DraftKings Loyalists
DraftKings launched DraftKings Predictions in December 2025, bringing the world's second-largest sportsbook operator into the prediction market space.
Why It's On This List
DraftKings Predictions operates in 38 states, with sports contracts available in 17 of them. The platform covers NFL, NBA, NHL, and MLB, with a focus on game outcomes and basic contract types. For the millions of existing DraftKings users, the prediction market is accessible through the familiar DraftKings ecosystem.
The Catch
Fees are higher than dedicated prediction market exchanges. The flat per-contract structure adds up fast for active traders — at $50,000 in volume, you're paying over $1,000 in fees compared to $50 on Polymarket. The market catalog is narrower than Kalshi or OG. And the platform is still early — having launched just three months ago, liquidity and feature depth are still developing.
DraftKings acquired Railbird Technologies (a CFTC-licensed exchange) to power its prediction market, giving it the regulatory foundation to grow. But it's competing against platforms with significantly more trading infrastructure and deeper liquidity.
Bottom Line
DraftKings Predictions is a reasonable option if you're already a DraftKings user and want to dip into prediction markets without creating a new account. For serious sports prediction trading, the dedicated platforms offer better value.
6. FanDuel Predicts — Early but Promising
FanDuel partnered with CME Group to launch FanDuel Predicts in December 2025, targeting states where traditional sports betting isn't available.
Why It's On This List
FanDuel is the largest sportsbook operator in the US, and its entry into prediction markets legitimizes the space. FanDuel Predicts offers contracts on NFL, NBA, and NHL outcomes, with pricing driven by market activity rather than house odds.
The Catch
FanDuel Predicts charges a 2% fee on your potential payout at checkout — a different model than other prediction markets and one that's more expensive for most trade sizes. The rollout has been limited to approximately five states so far, with expansion planned throughout 2026. Market depth and sport coverage are still very limited compared to the top platforms.
Bottom Line
FanDuel Predicts is worth watching as FanDuel scales its prediction market alongside its dominant sportsbook. But as of March 2026, it's not a competitive option for sports traders who have access to Kalshi, Robinhood, or Polymarket.
Prediction Markets vs. Traditional Sportsbooks for Sports
If you're coming from DraftKings, FanDuel, BetMGM, or any other sportsbook, the prediction market model has some fundamental differences worth understanding.
You're trading against other users, not the house. At a sportsbook, the operator sets the odds and profits from the built-in margin (vig). On a prediction market exchange, prices are set by supply and demand among traders. There's no house edge — the platform charges a flat fee on trades instead.
You can sell your position before the event resolves. This is the biggest practical difference. At a sportsbook, once you place a bet, you're locked in until the event ends (cash-out features are limited and operator-controlled). On a prediction market, you can sell your contracts at any time at the current market price. If the line moves in your favor during the first quarter, you can take profit without waiting for the final whistle.
Prediction markets are available in states where sports betting isn't. Because they're regulated by the CFTC at the federal level rather than by state gaming commissions, prediction markets can operate in states like California, Texas, and Florida where traditional sportsbooks don't have licenses. This is the single biggest reason sports prediction markets have exploded — they unlocked a massive population of sports fans who had no legal way to participate.
The age requirement is lower. Traditional sportsbooks require users to be 21+. Prediction markets are available to users 18 and older.
Tax treatment may differ. Prediction market winnings are currently reported as ordinary income (via 1099-MISC forms) rather than gambling income. The tax treatment of prediction markets is still evolving and may change. Consult a tax advisor for guidance specific to your situation.
State Availability: Where Can You Trade Sports?
All major prediction market platforms operate under CFTC federal regulation, which theoretically allows nationwide access. However, several states have challenged sports-specific contracts, and the legal landscape is in flux.
As of March 2026, the general picture is that sports prediction contracts are available in most US states, with restrictions or bans in specific states depending on the platform. States that have taken enforcement action against sports contracts include Nevada, Massachusetts, Maryland, New Jersey, Ohio, Michigan, Illinois, Connecticut, and Tennessee, among others. Court rulings have been mixed — some states have won preliminary injunctions, while federal courts have sided with platforms in others.
The CFTC, under Chairman Michael Selig, has asserted exclusive federal authority and pledged to fight state enforcement. Congressional legislation that could restrict sports prediction contracts has been introduced but not yet passed.
For traders, the practical advice is to check each platform's current availability page for your specific state. Non-sports contracts (politics, economics, weather, crypto) are generally unaffected by state-level restrictions and available more broadly.
How to Choose the Right Platform
The "best" platform depends on your trading style and priorities. Here's a simple decision framework.
You want the widest sports selection and deepest liquidity: Kalshi. No contest for breadth of markets, especially during NFL and NBA season.
You want the easiest possible setup: Robinhood. If you already have an account, you're minutes away from your first sports trade.
You want the lowest fees for active trading: Polymarket. The 0.10% taker fee is dramatically cheaper at scale.
You want community and social features: OG. Real-time chat, leaderboards, and a sports-first design.
You're already a DraftKings or FanDuel user: Try their prediction markets for convenience, but consider a dedicated platform for better pricing and selection.
You're a total beginner: Start with Kalshi's free demo account to learn the mechanics without risking real money.
Most serious sports prediction traders maintain accounts on two or three platforms. The incremental effort is minimal, and accessing the best liquidity across different platforms and market types is worth it.
Frequently Asked Questions (FAQ)
Are sports prediction markets legal?
Yes. Sports prediction markets operate under CFTC federal regulation and are available in all 50 states at the federal level. However, several states have challenged sports-specific contracts, and restrictions apply in some states. The legal landscape is evolving, with active litigation in multiple states as of March 2026.
What's the difference between a prediction market and a sportsbook?
At a sportsbook, you bet against the house, which sets the odds and profits from the margin. On a prediction market exchange, you trade contracts with other users at market-driven prices. The platform charges a small fee per trade instead of building margin into the odds. You can also sell your position at any time before the event settles.
Which platform has the lowest fees for sports trading?
Polymarket US charges the lowest taker fees at 0.10% of the trade amount. Robinhood charges $0.02 per contract flat. Kalshi uses a variable formula that peaks near 50/50 contracts. For a $1,000 position at even odds, approximate fees are: Polymarket $1, Robinhood $4, Kalshi $35.
Can I trade sports prediction markets if my state doesn't have legal sports betting?
Yes. Because prediction markets are regulated at the federal level by the CFTC, they're available in states where state-level sports betting isn't legal — including California, Texas, and Florida. Some individual states have restricted sports-specific contracts, so check your platform's availability page.
Do I need to be 21 to use prediction markets?
No. Prediction markets are available to users 18 and older, unlike traditional sportsbooks which typically require users to be 21+.
Can I combine multiple bets into a parlay on prediction markets?
Yes, on some platforms. Kalshi offers "Build Your Combo," Robinhood offers preset and custom combos (up to 10 legs), and OG supports parlays. Polymarket does not currently offer a parlay feature.
Do any platforms let me practice before risking real money?
Kalshi offers a free demo account where you can trade with mock funds using only an email address. This is unique among prediction market platforms and is the best way for beginners to learn the mechanics.
How are prediction market winnings taxed?
Most prediction markets, including Kalshi, report winnings as ordinary income via 1099-MISC forms. The tax treatment of prediction market profits is still evolving and may change. Consult a tax advisor for guidance specific to your situation.
What sports can I trade on prediction markets?
The major platforms cover NFL, NBA, NCAAB, NHL, MLB, soccer, tennis, golf, UFC, Formula 1, and esports. Market types include game winners, spreads, totals, player props, futures, and parlays. Coverage varies by platform — Kalshi has the widest selection.
Should I use a prediction market or a sportsbook?
It depends on your priorities. Prediction markets offer exchange-style trading with no house edge, the ability to sell positions early, and availability in all 50 states. Sportsbooks offer established interfaces, more established prop and in-play markets in legal states, and familiar odds formats. Many sports traders use both.
