Polymarket

Prediction market platform providing real-time market-derived probabilities for political, economic, and cultural events. Best for probabilistic forecasting workflows — gauging the likelihood of future events based on market consensus rather than polls or expert opinion. Unlike traditional financial data (SEC EDGAR, Nasdaq), Polymarket surfaces crowd-aggregated probability estimates for discrete outcomes. 4 endpoints available through Lava’s AI Gateway.

This provider is managed — no additional setup required.
