Reputation-based forecasting platform for serious probabilistic prediction
Last updated: July 2026
Metaculus is a forecasting platform — distinct from money-based prediction markets — where a community of forecasters makes probabilistic predictions on science, technology, geopolitics, AI, and world events, and is scored on accuracy over time rather than trading with real money. Instead of prices set by capital, Metaculus aggregates individual forecasts into a community prediction and a Metaculus-computed prediction, rewarding forecasters with reputation points and track records for calibration and accuracy. This makes it the go-to venue for rigorous, long-horizon forecasting where the goal is epistemic quality rather than speculation — it's widely used by researchers, policymakers, and the effective-altruism and AI-safety communities for questions where a liquid betting market doesn't exist or would be inappropriate. Participation is free. The considerations: because there's no money at stake, incentives differ from real-money markets — some argue markets with capital produce sharper signals, while others value that Metaculus avoids gambling dynamics and attracts thoughtful domain experts; resolution can take years for long-horizon questions; and it's a forecasting tournament, not a place to profit. But for anyone who wants high-quality, calibration-scored probabilistic forecasts on important long-term questions — and a track record system that rewards being right over time — Metaculus is the most respected platform of its kind and a fundamentally different tool from a trading-based prediction market.
