Polymarket vs Betfair: Full Comparison 2026
Polymarket and Betfair represent two distinct approaches to peer-to-peer prediction trading — each tailored to different user bases with markedly different operational models. This breakdown examines them side by side to assist your decision-making process.
Overview
Polymarket
Polymarket is a decentralised prediction exchange built on blockchain technology, established in 2020. The platform runs on the Polygon network, uses USDC for settlement, and specialises in real-world events spanning politics, technology, athletics, and current affairs. It operates without regulatory licensing as a fully decentralised protocol with non-custodial architecture. European participants can access the platform via PolyGram.
Betfair
Betfair is a London-headquartered peer-to-peer betting exchange established in 2000. The platform holds FCA authorisation and operates legally throughout the United Kingdom and European Union. Its market offerings concentrate on athletic events, though it also hosts markets on political outcomes. The exchange transacts in GBP and EUR, accepting conventional banking methods for deposits and withdrawals.
