Are prediction markets legal?

A neutral cross-venue prediction-market data platform: one normalized API across Polymarket, Kalshi, Limitless and Thales with research reports, on-chain whale tracking, bulk datasets and a backtest engine. It is sold as an API and MCP connector with Free, Pro $49, Desk $199 and Enterprise (contact sales) tiers.

There is no single answer for every location, venue and contract. The CFTC describes regulated U.S. event-contract markets, but access to a market-data API does not establish permission to trade. Check the relevant regulator’s current rules, the venue’s eligibility requirements and the specific contract before participating.
