About Polymarket UK

We believe the world makes better decisions when people can put money on what they believe — and be held accountable for it.

Our Mission

Polymarket UK is the UK's home of decentralised prediction markets — an open, transparent platform where anyone can trade on real-world outcomes.

We harness the wisdom of crowds: when millions of informed individuals stake real money on their beliefs, the resulting prices become the most accurate real-time probability forecasts available anywhere.

Our markets have consistently outperformed traditional polling, expert forecasts, and media consensus across elections, economic indicators, and major world events.

What We Stand For

Four principles guide everything we build at Polymarket UK.

🔓
Radical Transparency

Every trade, every position, every resolution is recorded on-chain and publicly verifiable. No black boxes, no hidden fees, no manipulation.

⚖️
Fairness First

Markets are resolved by our decentralised oracle network UMA. Disputes are adjudicated transparently — not by Polymarket alone.

🌐
Open Access

Prediction markets have historically been available only to institutions. We're changing that — anyone with £10 can trade alongside hedge funds.

🛡️
User Safety

We never hold your funds. Smart contracts settle automatically. We partner with licensed custodians for fiat onboarding in the UK.

Leadership Team

A team of traders, engineers, and policy experts united by a belief in market-based truth-seeking.
