Polymarket Taker Fee Update: $6.8M Weekly, 96.8% Share

Polymarket has expanded its monetisation with a new taker fee structure, effective under the updated model already showing strong take-rates. On-chain data suggests Polymarket earned about $6.8M in fees in its first full week, implying an annualised run-rate near $355M and roughly $1M per day. Sector-wide, weekly total prediction-market fees first rose above $7M, with most of the activity coming from Polymarket. Market share was even higher: Polymarket accounted for 96.8% of total on-chain prediction market fees during the same period. The new Polymarket taker fee model applies to categories including finance, politics, economics, culture, weather, and technology, while geopolitics/world-events remain fee-free for now. Importantly, trading volume appears resilient after the rollout, suggesting users are absorbing the higher costs. Polymarket also plans an infrastructure change: Polymarket USD will replace bridged USDC.e as collateral, backed 1:1 by Circle’s USDC. The upgrade includes a rebuilt trading engine and smart-contract updates, and all open orders will be cancelled during a short maintenance window. With ICE reportedly committing $600M, institutional interest is rising, but US and EU regulatory scrutiny is also increasing—traders may want to watch whether Polymarket can hold volume while maintaining the Polymarket taker fee headroom. For traders, the key read-through is that the pricing power is improving without an immediate activity hit, which can support tighter liquidity and more predictable fee dynamics—though regulatory and maintenance events can still drive short-term volatility around specific market pairs.
