Metaculus Review

Metaculus is a reputation-based forecasting platform used by researchers, policy think tanks and superforecasters. Instead of trading contracts you submit probability estimates and are scored on calibration and accuracy over time.

Metaculus is free to use. There is no trading and therefore no fee schedule. Some grant-funded tournaments pay cash prizes to top forecasters.

Liquidity is not a meaningful concept here — the aggregated community forecast is derived from all submissions rather than an order book. Question volume is high on AI, geopolitics, science and public policy topics.

The interface is dense and research-oriented, with detailed question histories, forecaster leaderboards and comment threads. Casual users may find the learning curve steep; serious forecasters find it best-in-class.

There is no money at risk on Metaculus, so the traditional safety questions do not apply. The platform is operated by a US-based nonprofit and has been running continuously since 2016.

Metaculus is fully available across Europe with no restrictions. It is one of the best entry points for European users interested in forecasting without regulatory friction.

Metaculus is not a direct competitor to Probly, Polymarket or Kalshi — it is a complement. Use it to sharpen your forecasting skill and to cross-check community estimates against real market prices on cash exchanges.

Если хотите оттачивать прогностику на реальных сложных вопросах — Metaculus непревзойдён.
