Polymarket set to earn around $1 million a day with upcoming fee structure

Polymarket is poised to earn approximately $800,000 to $1 million per day once its new taker fee parameters take effect on March 30, 2026, based on recent trading volumes.

This projection is derived from the platform’s strong activity levels as of March 24, 2026. Over the past 30 days, Polymarket recorded roughly $9.55 billion in trading volume. At current levels, this implies monthly revenue of about $25 million, assuming an effective blended taker fee rate, which annualizes to around $300 million or roughly $833,000 daily.

Starting March 30, Polymarket will expand taker fees to additional market categories, including finance, politics, economics, culture, and weather. Certain high-profile areas like geopolitics and world events will remain fee-free on Polymarket.

The new fee structure on Polymarket is dynamic and probability-based. Fees are calculated using the formula:

The fees will fund a Maker Rebates Program that pays daily USDC rebates to liquidity providers, aiming to improve market depth. This creates an inverted parabolic curve, where fees peak when shares trade near $0.50, or 50% probability, highest uncertainty, and decline sharply toward the extremes near $0, where many small trades may incur zero or negligible fees.

For context on current parameters pre-March 30, crypto markets on Polymarket use a 0.25 fee rate with about 1.56% peak effective rate. As for sports, the platform uses 0.0175 with around 0.44% peak. Post-update rates will shift, with crypto peak rising to around 1.80%, and rebates varying by category, such as up to 50% in Finance.

Positioning against Kalshi?

The new structure enhances Polymarket’s ability to compete with Kalshi, a U.S.-regulated prediction market that employs its own dynamic, probability-based fees. While introducing modest costs where none existed on many markets, Polymarket’s model remains generally more trader-friendly than Kalshi’s, particularly for edge-probability trades or fee-free categories. Kalshi currently reports an annualized revenue run-rate of $1.5 billion, highlighting the growth potential in the sector.

By recycling fees into maker rebates, Polymarket aims to boost liquidity and transparency without imposing heavy burdens.
