Prediction market reviews, reviewed for real

We open real accounts on every platform, claim the bonuses, message support and read the fine print. Here’s where each one wins — and our full reviews.

Best prediction markets by category

We score every platform the same way, but they do not all win at the same thing. Best for sports: Kalshi has the broadest catalog, with DraftKings and FanDuel close behind for states without a sportsbook. Best for politics: Polymarket leads on global volume, Kalshi on the regulated US slate, and PredictIt remains the political specialist. Best in one app: Kalshi covers sports, politics, economics and culture under a single regulated roof.

How we review & rate platforms

Every score is a weighted composite we calculate ourselves — not a number an operator can buy. We open and fund a real account, claim the bonus, place and exit trades, message support, investigate ownership and complaints, then weigh app-store ratings, user sentiment, complaints, bonus value, popularity, downloads, market share and cited media coverage into one rating. Scores are independent and re-run whenever a platform meaningfully changes.
