The deepest liquidity in the category, now reaching US traders through an intermediated, CFTC-overseen route — with the most markets of anyone.
Each platform is scored against the same five-part rubric, weighted toward regulation and reliable payouts. Scores are illustrative editorial judgments, not investment advice.
Began intermediated US access in December 2025 through a CFTC-licensed exchange and clearinghouse; standing is improving but newer than Kalshi.
The broadest and deepest market menu in the set, especially politics and world events.
Low onchain trading costs historically; intermediated US access may carry its own fee schedule.
Polished interface, though the US route adds an onboarding step.
Reliable onchain settlement; US-side payout terms follow the intermediary.
Funding and fee details as of June 2026 and illustrative. Verify current terms with the platform before depositing.
Nothing else comes close on the number of markets, especially around elections.
The US route added steps versus the old onchain flow, but it is good to have a regulated path.
Deep liquidity on the big markets; I still check the resolution source carefully.
Reviews are illustrative editorial examples, not verified customer testimony.
Polymarket is available to verified US-based users. Eligibility still depends on your age and state rules, which can change.
We don't earn from platforms and don't provide sign-up or affiliate links. Where a platform is available to you, open an account directly through its own website, and only after you've read the rules and your eligibility.

A clear regulator does not make a platform safe to over-trade. Prediction markets can lose you money; trade only what you can afford to lose, never to chase losses, and never on borrowed money.
