Polymarket vs Betfair Exchange: prediction markets vs betting exchanges
Updated 12 Oct 2026
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 | No UK licence (Polymarket US is CFTC-regulated) | UK Gambling Commission |
| Currency | USDC | GBP / EUR |
| Commission | Taker fee up to 0.07·p(1−p); 0% on geopolitics | Commission varies — check current schedule |
| 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 global political and geopolitical markets, Polymarket's international book is usually the deepest — but it is not available in the UK.
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.
