Summary

Betfair Exchange is a peer-to-peer betting exchange that functions as a real-money prediction market, allowing users to trade on outcomes of events at market-determined odds. It aggregates dispersed information into prices through competitive bidding, making it a practical example of mechanism design for information elicitation and forecasting.

  • Real-money markets create strong incentives for accurate forecasting, making Betfair a natural experiment in information aggregation
  • Demonstrates practical mechanism design: market rules, liquidity provision, and price formation under real-world constraints
  • Used by researchers studying prediction market accuracy, crowd wisdom, and the efficiency of decentralized information aggregation
  • Relevant to AI safety discussions on forecasting, calibration, and market-based mechanisms for aggregating expert judgment
