Betfair Exchange vs Smarkets

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.

Smarkets was founded in 2008 by former equities trader Jason Trost and software engineer Hunter Morris in London to disrupt legacy bookmakers with financial-grade exchange architecture. Built on Erlang-based event-driven matching infrastructure, Smarkets operates as an agile peer-to-peer prediction marketplace covering global sports, political elections, macroeconomics, and current affairs.

Distinguished by its industry-defining flat 2% commission structure on net market winnings, Smarkets offers unmatched liquidity and transparent order books. The exchange actively welcomes quantitative traders and high-volume market makers by maintaining transparent APIs and strictly prohibiting account restrictions or limits on winning traders.
