Questimations pulls data from the world's leading prediction markets, normalises and analyses it, then powers consumer products like Predictions.io — turning raw market signals into actionable crowd intelligence.
We ingest data from the world's major prediction markets in real time — normalising questions, odds, and outcomes into a unified schema.
Proprietary algorithms combine signals across markets to surface the most calibrated probability estimate available — the wisdom of all markets at once.
Every resolved event is archived with full probability histories, enabling back-testing, accuracy benchmarking, and research applications.
Low-latency feeds deliver live probability updates, volume shifts, and market movements — ready to plug into any application or dashboard.
Our data powers Predictions.io — a forecasting app where users engage with market data, compete on accuracy, and build their forecasting track record.
EU-based, privacy-first architecture. We never sell personal data and maintain full compliance across all products built on our platform.
