[Learn what changed](https://betteranalyst.com/formula-bot-is-now-better-analyst) Live and historical forecast probabilities from Polymarket, the largest prediction market. Each market asks a question about a future event (an election, a Fed decision, a sports result, a product launch, a crypto price) and its price is the crowd's probability that the outcome happens. The API covers every active and resolved market: questions and outcomes, current probabilities, trading volume, liquidity, open interest, end dates and resolutions, plus full price history that goes back to a market's launch. Use it to track how expectations moved around news, compare forecasts across events, or chart the odds of anything the market covers. No API key required.
