Frequently Asked Questions
Where can I find the latest Polymarket news?
Right here. PredictionNews tracks 256 active Polymarket stories, each clustered from original reporting and summarized for prediction-market operators, traders, and regulators, and refreshed throughout the day.
Are prediction markets legal in the US?
Federally, yes. Platforms like Kalshi and Polymarket US operate as CFTC-regulated event-contract exchanges, which is why they're available even in states where sports betting is banned. Legality is contested at the state level, especially for sports contracts, the regulatory fight PredictionNews tracks daily.
Are prediction markets the same as gambling?
Legally, no. They're overseen by the CFTC as financial event contracts, not by state gambling regulators, and you trade "Yes"/"No" shares priced between $0 and $1 rather than betting against a bookmaker's odds. That distinction is at the heart of the current regulatory debate.
How do prediction markets work?
You buy shares in a "Yes" or "No" outcome priced between $0 and $1. The price reflects the market's implied probability of the event. Correct predictions settle at $1 per share, incorrect ones at $0. They function like an exchange, not a sportsbook.
