Polymarket and Betfair represent two distinct approaches to peer-to-peer prediction exchanges, each catering to separate user bases with markedly different operational models. This breakdown examines their strengths and weaknesses to guide your platform selection.

Overview

Polymarket

Polymarket emerged in 2020 as a blockchain-powered prediction market built atop the Polygon network. Transactions occur in USDC, with coverage spanning current affairs, electoral outcomes, digital assets, and athletics. The platform operates without regulatory licensing and functions entirely on decentralised infrastructure with non-custodial wallets. European participants can access the platform through PolyGram.

Betfair

Betfair, established in 2000, is a London-headquartered peer-to-peer betting exchange holding FCA authorisation. The platform maintains legal status across the United Kingdom and European Economic Area. Its primary emphasis rests on athletic competitions, supplemented by a smaller selection of geopolitical forecasting. Settlement occurs via GBP and EUR with conventional financial institution transfers.
