Polymarket Introduces Trading Fees on US App & Crypto Prediction Markets

Polymarket — the decentralized prediction market — has started charging trading fees on its US app and short-duration crypto prediction markets, marking a big shift from its long-standing zero-fee model.

Under the new schedule, takers on the Polymarket US app will pay 1 basis point (0.01 %) per trade, while 15-minute crypto markets now carry dynamic taker fees that vary based on odds and market conditions. This is Polymarket’s first direct revenue stream as it expands into mainstream trading and regulated markets.

The fees are designed to help the platform fund liquidity incentives, improve market structure by discouraging purely latency-based arbitrage, and support deeper order books — rather than simply being a revenue grab.

Meanwhile, Polymarket’s US app is currently in private beta following regulatory approval steps and gradual rollout after years of restricted access.

So here’s the question for traders and prediction market fans: Does this fee introduction signal maturation of the platform and prediction market space — or will it hurt user engagement by ending the no-fee promise? Drop your thoughts
