Polymarket and Betfair represent two distinct approaches to peer-to-peer prediction exchanges — each designed for different user bases with markedly different operational structures. This breakdown examines them across key dimensions to inform your platform selection.

Overview

Polymarket

Polymarket is a decentralised prediction market built on blockchain technology, established in 2020. The platform utilises the Polygon network, transacts in USDC, and specialises in current affairs, electoral forecasting, digital assets, and athletic events. Operating without regulatory licensing and maintaining full decentralisation, it remains non-custodial. European participants access the platform through PolyGram.

Betfair

Betfair is a London-headquartered peer-to-peer betting exchange established in 2000. Holding FCA authorisation, it operates legally throughout the United Kingdom and European Union. The platform concentrates on athletic markets as its primary offering, supplemented by a smaller selection of electoral forecasting opportunities. It processes transactions in GBP and EUR through conventional financial institutions.
