Catalogue
57 platforms in the catalogue, researched using public documentation. Country rules shown for United States. Missing evidence stays unverified. Reviews distinguish document research from any recorded account test; a listing does not establish your eligibility to trade. Every platform is also a row in the platform dataset, downloadable as platforms.csv. For the order we would pick them in, see the best prediction markets, ranked.
CFTC-regulated event contract exchange
7.7 out of 10Prelim
KalshiEX is a CFTC-designated contract market and its Member Agreement names no US state as restricted. State court orders block some contract categories in Nevada, Washington and Michigan; elsewhere its contracts are available. Kalshi is in litigation with about 20 states, so this can change quickly.
CFTC-regulated US event-contract exchange run by QCX LLC, USD only
7.3 out of 10Prelim
QCX LLC publishes no list of eligible or excluded states. A Nevada court granted a preliminary injunction against QCX LLC d/b/a Polymarket US on 29 May 2026 (Nevada Gaming Control Board). Missouri's Attorney General has sent a cease-and-desist over sports contracts, and New York has announced a lawsuit; neither state is marked closed because the operator has not said it geoblocks them.

Recorded country restrictions affect the order of this list. An unverified status means evidence is missing; it does not mean approval or prohibition. Read the source and the operator’s current account requirements in each review.
The register is empty. An operator is listed only once we hold evidence we can publish — non-payment, a fabricated licence, a phishing clone or a manipulated resolution. Until then this panel stays empty rather than carrying a name we cannot support.
Full blacklist and criteria →We list 57 that we have researched from their own documents: US exchanges designated by the CFTC, brokers that sell event contracts, sportsbook-run apps, offshore crypto order books and play-money sites. New venues open often, so a platform missing here is one we have not yet documented, not a judgement on it.
Exchanges the CFTC has designated as contract markets may list event contracts nationally. Among those we review: Kalshi, Polymarket US, Interactive Brokers ForecastTrader (through ForecastEx), ProphetX and Novig. Several states dispute sports contracts in court, and offshore crypto venues such as polymarket.com exclude US residents.
A CFTC-designated exchange trades in dollars, requires identity verification and is supervised by a federal regulator. A crypto prediction market settles in tokens such as USDC on a blockchain; many name no regulator, and many exclude US residents. Each review states which kind a platform is and what that means for your money.
