Polymarket vs Betfair Exchange: prediction markets vs betting exchanges
Both Polymarket and the Betfair Exchange match buyers and sellers via order books — the same fundamental mechanism. The differences are jurisdictional, structural, and increasingly important.
| Feature | Polymarket | Betfair Exchange |
|---|---|---|
| Founded | 2020 | 2000 |
| Regulator | None | UK Gambling Commission |
| Currency | USDC | GBP / EUR |
| Commission | 0% | 2–5% on net winnings |
| UK/EU access | Geo-blocked | Available (jurisdiction-dependent) |
| Beyond sport | Yes — politics, economics, crypto | Limited non-sport markets |
Betfair Exchange pioneered the peer-to-peer betting model in 2000. Polymarket adapted the same mechanic for the crypto era — adding 24/7 global access, USDC settlement, and a content focus on politics and economics rather than sport.
For sporting markets, Betfair Exchange has incomparable liquidity. For political and event markets, Polymarket is now the deepest book in the world.
Frequently asked questions
Is Betfair a prediction market?
Betfair Exchange functions identically to a prediction market — peer-to-peer order books on event outcomes — but is regulated as a betting exchange under UK law rather than as a derivatives venue.
