Prediction market reviews

Our reviews answer one question for each platform: what does the public record say you are signing up for? That covers who operates it, how the CFTC regulates it, where it is available, what it charges and what any offer really requires.

How we review prediction markets

Every review on Chance Ledger is a documentary review. We have not opened accounts, deposited money or placed trades, and we do not claim to have. Instead, each review draws on:

• Regulatory records: the CFTC’s list of designated contract markets, plus CFTC press releases and staff letters.
• Court and state records: appellate opinions, Supreme Court dockets and state attorney-general filings that affect where a platform can operate.
• Operator documents: official fee schedules, help-center articles, terms of service and promotion terms.

Where a fact rests only on secondary reporting, the review says so. Where we could not confirm a fact at all — an exact fee coefficient, a state list, a minimum age — we leave it out or mark it unverified. We do not assign scores out of 10; reviews end with a written verdict, and our methodology explains the criteria. Hands-on testing will add things the record cannot show, such as withdrawal times, app usability and how customer support responds.

Every review follows the same structure so you can compare them directly: a summary verdict, who the platform suits and who should avoid it, regulation and legal status, availability by state, sign-up offer and terms, markets, fees with worked examples, deposits and withdrawals, pros and cons, and alternatives.

Each review is re-checked at least every 30 days, and sooner when a court ruling or fee change lands.

Our prediction market reviews

All ten platforms we track

We track ten regulated platforms. The side-by-side table of all ten, covering regulation, markets, fees, availability and verified offers, lives on our prediction market comparison page. Each cell comes from a sourced, dated brand record, and “Not verified” means we could not confirm the fact in an official source.

Platforms without a full review yet

Five of the ten are CFTC-regulated but do not have a standalone review. In each case the reason is a gap in what we can verify, not a judgment against the platform.

• Interactive Brokers ForecastTrader: fees are clearly published, but state availability details and the current incentive coupon rate are unconfirmed.
• Coinbase Predictions: markets are operated by Kalshi, and Coinbase publishes no fee formula or broker-fee amount, so a cost section would be incomplete.
• Crypto.com Predictions: the fee formula is official, but the full list of states where sports are unavailable is not.
• Webull: the per-contract fees are official; the broker entity name and state restrictions are not confirmed.
• DraftKings Predictions: the $0.01 transaction fee is official, but the DKeX exchange fee, the sports state list and the current offer are not.

We will add reviews as those gaps close. Until then, you can compare them on fees and markets in the prediction market comparison or see how the top five rank in our best prediction markets list.
