Polymarket and Betfair represent two distinct approaches to peer-to-peer prediction exchanges, each catering to different trader profiles and jurisdictions. This breakdown examines their key differences to guide your platform selection.

Overview

Polymarket

Polymarket emerged in 2020 as a decentralised prediction platform built atop the Polygon blockchain. It transacts exclusively in USDC, with market coverage spanning current affairs, political outcomes, digital assets, and athletic events. The platform operates without regulatory oversight and maintains a non-custodial structure. European participants access the ecosystem via PolyGram.

Betfair

Betfair, established in 2000, functions as a UK-domiciled peer-to-peer betting exchange holding full FCA authorisation. It maintains legal standing throughout the United Kingdom and European Union, with specialisation in athletic contests alongside a modest selection of current-events outcome markets. The platform operates using GBP and EUR, backed by conventional financial infrastructure.
