UK Betting Exchanges: Bridging Sports Betting & Prediction Markets

Defining the Shift: Betting Exchanges vs Prediction Markets

Prediction markets and sports betting both allow people to speculate on future outcomes, but they operate in fundamentally different ways. While sports betting relies on bookmakers and fixed odds, prediction markets use open trading and crowd-driven pricing to forecast probabilities. A betting exchange is a peer-to-peer venue where users back and lay outcomes under a gaming licence, while a prediction-market exchange trades event contracts as derivatives. Traditional back/lay exchanges (Betfair, Smarkets, Matchbook) ask bettors to either back an outcome or lay it, with lay liability scaling with stake.

Matchbook: Dual Formats Under One Roof

A 15-year-old UK sports betting exchange wants to do something no one else has quite pulled off: offer both prediction markets and traditional sports betting under one roof. Matchbook, a UK-based peer-to-peer betting exchange, is preparing to enter the US market with a platform combining prediction markets and sports betting. In January 2026, the company launched a dedicated prediction market platform in the UK, offering simple binary yes/no contracts across sports, politics, and other events.

The contracts are priced in probability terms. Matchbook customers will gain access to a dedicated ADI Predictstreet prediction market hub featuring a full suite of FIFA World Cup 2026 prediction markets, including tournament winner, group-stage outcomes, top scorer, and in-play predictions, alongside live streaming of all 104 tournament matches. We now operate the only exchange platform in the world running multiple licensed prediction market brands under a single regulatory framework.

Betfair Predicts: Probability Interface Beta

Betfair has quietly soft-launched a prediction markets product, Betfair Predicts, that takes its pricing from the brand’s exchange platform. The peer-to-peer product, which is the Betfair Exchange wrapped in a prediction markets interface, is currently in beta mode and being trialled by a small, select group of customers. Similar to the likes of Kalshi and Polymarket, the Betfair Predicts homepage features a wall of binary markets under the ‘Trending’ tab, as well as markets covering the biggest sports, politics and culture.

Odds are presented as percentage probabilities, though there is the option to switch to decimal and fractional prices, while the back (‘Yes’) and lay (‘No’) buttons are light blue and pink. A total of £84bn was matched on the Betfair Exchange in 2025, which was almost a 10% increase year on year, and the company said customer feedback has shown there is demand for a prediction markets product.

Smarkets: Regulated Volume and Frontend Overhaul

Earlier this year, fellow UK exchange Smarkets overhauled its frontend to a predictions markets interface, supplanting the traditional exchange layout and switching to percentage probabilities. Smarkets operates one of the world’s largest prediction markets and sports betting exchanges, processing billions in annual volume across more than one million customers in regulated markets worldwide. The company already has a foothold with its SBK product, which packages the exchange as a traditional sportsbook app.
