1. Polymarket – Best Prediction Market for Contract Variety
Polymarket is the largest prediction market in the world by volume, and its U.S. app now runs on a CFTC-regulated exchange after the company acquired QCX and QC Clearing.
The breadth is the selling point. Traders can take positions on the World Cup, presidential nominations, Federal Reserve decisions, weather, and awards shows inside a single mobile app.
- 📈 Markets Available: Sports, politics, economics and financials, crypto, weather, entertainment and pop culture
- 📱 App: Available on iOS and Android. Polymarket operates as a mobile-only product in the United States, so there is no desktop trading option
- ⭐ Promo Code: ACTION
- 🎁 Sign Up Bonus: Deposit $10, Get a $20 Trading Bonus!
- 📍 Eligible States: Live in most states and D.C. Not currently available in AZ, IL, MA, MD, MI, MT, NV, or OH, and Minnesota enacted a ban effective August 1, 2026
- 🔞 Required Age: 18 and up, though a handful of states set a higher minimum
2. FanDuel Predicts – Best Prediction Market App for Nationwide Access
FanDuel Predicts is a standalone app operated by FanDuel Group in partnership with CME Group, which serves as the underlying designated contract market for every trade.
The structure is worth understanding before you sign up. Financial, economic, commodity, and crypto contracts are available nationwide, while sports event contracts are restricted to a smaller group of states.
- 📈 Markets Available: Sports event contracts, financials, economics, commodities, crypto
- 📱 App: Available on iOS and Android, and existing FanDuel customers can log in with their current credentials
- ⭐ Promo Code: No Code Needed
- 🎁 Sign Up Bonus: Sign Up & Unlock Your Offer!
- 📍 Eligible States: Non-sports contracts are live in all 50 states plus D.C. Sports contracts are limited to AK, AL, CA, DE, FL, GA, HI, ID, MN, NE, NM, ND, OK, RI, SC, SD, TX, and UT
- 🔞 Required Age: 18 and up in most states, rising to 19 or 21 in others
3. Kalshi – Best Prediction Market for Politics and News Traders
Kalshi was the first federally regulated event contract exchange in the United States, and it remains the deepest option for traders who want more than sports on the board.
Its welcome offer is also the largest on this list, scaling with your activity rather than paying out a flat credit.
- 📈 Markets Available: Sports, politics and elections, economics, weather, entertainment, crypto
- 📱 App: Available on iOS and Android, with full trading also supported through the Kalshi desktop site
- ⭐ Promo Code: ACTION
- 🎁 Sign Up Bonus: Trade $25, Get up to $500!
- 📍 Eligible States: Available in more than 40 states. Not offered in AZ, IL, MA, MD, MI, MT, NV, or OH
- 🔞 Required Age: 18 and up with a valid U.S. residential address in an eligible state
4. Novig – Best Prediction Market App for Sports Traders
Novig received its CFTC designation in June 2026 and completed the switch from a sweepstakes product to a federally regulated, sports-only exchange on August 4.
It is the most sportsbook-like app in this group. Prices display as American odds, there is no house edge on matched trades, and users can post their own price into the order book instead of accepting what is showing.
- 📈 Markets Available: Sports only, covering the NFL, MLB, NBA, NHL, soccer, golf, tennis, UFC, and college sports, with multi-leg combo trading on eligible markets
- 📱App: Native iOS and Android apps with portfolio tracking built in. Novig is a mobile-first platform
- ⭐ Promo Code: ACTION
- 🎁 Sign Up Bonus: Spend $25, Get $50 in Novig Coins!
- 📍 Eligible States: Live nationwide with the exception of Arizona, Michigan, and Nevada
- 🔞 Required Age: 21 and up
5. DraftKings Predictions – Best Prediction Market for New User Bonus Value
DraftKings Predictions is the newest major entrant, built out after DraftKings moved into the event contract space, and it carries the biggest headline bonus number of any app here.
That $200 arrives in stages rather than all at once, so it rewards traders who plan to stick around past the first week.
- 📈 Markets Available: Sports event contracts plus financial and economic markets
- 📱 App: Available on iOS and Android, plus a desktop web version, and existing DraftKings customers can log in with their current account
- ⭐ Promo Code: No Code Needed
- 🎁 Sign Up Bonus: Trade $5, Get $150 in Predictions Dollars!
- 📍 Eligible States: Live in 38 states, including California, Texas, Florida, and Georgia. Sports contracts are available in a narrower subset
- 🔞 Required Age: 18 and up in most eligible states
Best Prediction Market Apps: Final Thoughts
There is no single winner here, only different fits. Kalshi and Polymarket give you the widest range of contracts, FanDuel Predicts offers the broadest state footprint, Novig is the sharpest tool for sports specialists, and DraftKings Predictions leads on raw bonus value.
Signing up for more than one is the move most active traders make, since prices on the same event rarely line up perfectly across exchanges.
Disclaimer: Prediction markets provide real-time probability estimates based on traded contracts. These prices reflect market sentiment and are not a guarantee of future outcomes. Trading event contracts involves risk. State availability, promotional terms, and age requirements change frequently, so confirm current details with each platform before signing up.
