Are prediction markets accurate?

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.

Evaluate market probabilities against realized outcomes across a defined sample. Group predictions by probability and horizon, then compare observed frequencies; include liquidity, bid-ask spread and settlement rules. A single successful forecast does not establish calibration, and a quoted probability is not a guarantee.
