Betfair Exchange was founded in 2000 by Andrew Black and Edward Wray, revolutionizing international sports wagering and event forecasting by replacing traditional bookmaker markups with a peer-to-peer orderbook. By allowing traders to both "back" (bet for) and "lay" (bet against) outcomes, Betfair introduced financial market microstructure—complete with order depth, bid-ask spreads, and cash-out trading mechanics—to sports, horse racing, and political markets.

As the largest and most liquid betting exchange in the world, Betfair serves as the global benchmark for real-time probability discovery. Its political prediction markets, most notably the US Presidential Election contract, routinely process hundreds of millions of pounds in traded volume per cycle, making Betfair's orderbook a primary reference point for international news organizations and quantitative research analysts. Betfair operates on a commission model, charging a small percentage on net winning positions rather than taking directional risk against its users.

Now operating as a flagship brand within Flutter Entertainment plc (NYSE: FLUT)—the world's largest online gambling enterprise—Betfair remains a central liquidity engine. With robust regulatory oversight from the UK Gambling Commission and Malta Gaming Authority, advanced programmatic API access, and global liquidity pools, Betfair bridges traditional gaming markets with high-frequency quantitative event trading.
