How we compare

We rate platforms on regulation and legal standing, US availability, market breadth by category, fee model, funding and withdrawal methods, trading tools (order types and API access), and the new-user bonus our referral link delivers, if any. Where we have a referral relationship we say so and link accordingly; every other platform gets a plain informational link. Category strength reflects each platform's typical market depth and breadth, not a promise of liquidity on a specific event. Fee and bonus terms change frequently — always confirm the current details on the platform before trading.

Frequently Asked Questions

What is the best prediction market platform in 2026?

There is no single best platform — it depends on what you trade and where you live. Kalshi is the best all-round CFTC-regulated option for US traders across economics and politics. Polymarket has the deepest liquidity globally and leads on politics and world events. For sports, Fanatics, Novig and ProphetX are purpose-built exchanges, and Kalshi carries large mainstream US sports volume.

Which prediction market is best for sports?

For US sports, Kalshi carries heavy volume on mainstream leagues, while Novig (no-vig exchange) and ProphetX (peer-to-peer) are dedicated sports exchanges, and Fanatics Markets ties into its sportsbook. OG also offers sports alongside crypto.

Which prediction market is best for politics?

Polymarket leads on politics and global events with the deepest liquidity. Kalshi is the strongest CFTC-regulated US option for political and economic contracts, and IBKR offers election contracts to eligible US residents.

Which prediction markets are legal in the US?

Kalshi, OG (by Crypto.com), Gemini, Coinbase, Fanatics, IBKR, Novig and ProphetX operate on CFTC-regulated or federally regulated US infrastructure. Polymarket’s global site is geoblocked for US IPs; a separate US entity exists but is not covered here.

Do prediction markets offer signup bonuses?

Some do. Through our referral links, Kalshi offers a trade-$25-get-$25 new-user bonus (bonus funds expire 7 days after they unlock) and OG offers a trade-$10-get-$10 bonus. Bonus terms change often — check the platform for current details before signing up.

How do prediction market fees work?

Most platforms charge a small fee tied to profit or per contract rather than a traditional sportsbook vig. Kalshi uses a formula-based fee (~1–2% of profit), Polymarket is low and spread-based, and exchanges like Novig advertise no vig. Always check the current fee schedule.
