Polymarket has added trading fees to its 15-minute crypto markets, introducing taker-only charges on a subset of high-frequency prediction products.
The affected markets allow users to place short-term “up or down” bets on major cryptocurrencies such as bitcoin, ether, solana, and XRP, with contracts resolving every 15 minutes. While most Polymarket markets remain fee-free, the platform said the new fees will support a Maker Rebates Program.
Collected fees will be redistributed daily in USDC to market makers, with the goal of improving liquidity and tightening spreads. Although specific fee levels were not disclosed, documentation suggests fees could reach up to 3% depending on trade size and probability.
The update follows increased activity in short-duration crypto markets, which have attracted algorithmic traders and arbitrage strategies since launching in late 2025. The move signals a deliberate evolution in Polymarket’s market structure.
