Start with CFTC designated contract markets.
US prediction-market research is less about “the global leaderboard” and more about which product you are actually allowed to use. Kalshi and ForecastEx are CFTC designated contract markets. That is why Kalshi leads this page even though Polymarket scores higher globally — Polymarket is not a US-licensed exchange.
How to choose in the US
Primary source before any GammaPredict shortlist: CFTC DCM filings. A listing on that page is not a state-by-state availability map and is not legal advice.
Use this order: (1) confirm you want a regulated event-contract path, (2) complete KYC only on platforms you intend to use, (3) compare politics specialists if elections are the job, (4) treat crypto venues as restricted research unless terms clearly allow you.
If you are still exploring concepts without capital, Manifold is a useful practice layer. If you need economy or weather contracts, keep ForecastEx on the watchlist beside Kalshi.
Kalshi
Primary US-regulated event-contract research start for politics, economy, weather and sports contracts.
PredictIt
Politics-specialist overlay for elections and policy markets — compare alongside Kalshi.
Manifold
Community forecasting practice layer before real-money venues.
ForecastEx
US event-contract exchange watchlist for economy and macro themes.
Polymarket
Strong global crypto benchmark — frequently restricted for US users; confirm current terms first.

US politics path
For elections and policy markets, open Kalshi vs PredictIt before funding either account. Check contract wording, limits and resolution sources — two “same headline” markets can settle differently.
US sports & crypto path
Sports-interested US users should still begin with eligibility. Kalshi may list sports-related contracts; crypto sports venues such as Azuro or SX Bet are research comparisons, not automatic US recommendations. See sports prediction markets.

FAQ
What is the best prediction market in the USA?
Kalshi is a CFTC designated contract market and our primary start for eligible US persons. ForecastEx is the other DCM on the watchlist. PredictIt is the politics specialist — verify live CFTC status. This is not the UKGC or EU-crypto list.
Can Americans use Polymarket?
Often there are restrictions. Do not assume access. Verify Polymarket’s current terms and prefer Kalshi / PredictIt research paths when in doubt.
Do US platforms require KYC?
Kalshi and PredictIt are account/KYC oriented. Wallet-first crypto venues may look lower-friction but can be restricted or higher custody risk.
Is this legal or tax advice?
No. GammaPredict is an editorial comparison guide only. Confirm state access, product classification and tax treatment yourself.
