Best Prediction Market Apps in the US, June 2026
Prediction markets in the US are federally regulated trading platforms that allow you to buy and sell Yes/No contracts on real-world events. There's no house edge and prices move in real time to reflect the implied probability of an outcome. You can sell your position before an event resolves, meaning you can lock in profit before the result is confirmed.
You can predict the outcome of markets including sports, politics, economics, crypto, culture and more.

Kalshi: Best Overall
Kalshi is regulated by the CFTC Designated Contract Market and has the widest market range available. Players can make transactions using debit cards, bank transfers, PayPal, Venmo and crypto. New players receive a $10 trading bonus and can join from as little as $1.
Polymarket: Best for Sports and Trending Markets
Polymarket has the highest number of users of any prediction market platform. They re-entered the US market in 2025 via QCX LLC, a CFTC-regulated DCM. You can access the app using a code to skip the waitlist and start trading right away. Markets cover politics, crypto, culture and more.
All trading is done in USDC, but you can deposit and withdraw using crypto, card and bank transfer via MoonPay and Robinhood. Fees are negligible when using crypto and payouts are typically under 24 hours.
Crypto.com / OG Markets: Best for Crypto Users
More similar to traditional trading platforms, these two operators use an order book model. Markets cover sports, politics and culture, and new players can claim a welcome offer of between $50 and $100.
Underdog Predict: Best for Beginners
Underdog is ideal for beginners, using a simple buy-sell model. There are also parlay-style combos which will be familiar to DFS players. New players can get a bonus of up to $75 when making a $5 trade, with a minimum deposit of $10.
What Are Prediction Markets?
Prediction markets are platforms where outcomes are traded via Yes/No contracts, priced between $0.00 and $1.00 to reflect the likelihood of an outcome. If a contract is priced at $0.70, the market implies a 70% chance of that event happening. Winning contracts settle at $1.00; losing contracts settle at $0.00.
Are Prediction Markets Legal?
Yes, prediction markets are legal in the US and are regulated by the CFTC. They operate as federal financial instruments rather than bets, similar to trading stocks. Because they fall under federal rather than state jurisdiction, they are legal in many states where sports betting is not.
Most platforms are unavailable in the following states: AZ, IL, MA, MD, MI, NV, NJ and OH. Montana has fully restricted Polymarket specifically.
