Polymarket adds receiving payments to 15-minute crypto markets

Prediction market platform Polymarket has updated its documentation to show that 15-minute crypto up/down markets now carry receivables.

In the newly updated “Trade Fees and Maker Discount Program” sections of the website's documentation, the Prediction Markets platform has made it possible to offer liquidity incentives to market makers by accepting only payments on 15-minute crypto markets.

Payments collected from receivers are distributed to liquid providers in the USDC stablecoin instead of being held by the protocol. The change will only apply to these short-term crypto markets, while most polymarket markets will remain free of charge.

The payouts vary based on market opportunities, with the highest payouts occurring when prices are 50% off. However, it drops to zero as the odds approach 0% or 100%. Based on the examples cited in the document, a paddle trade of 100 shares valued at $0.50 would cost approximately $1.56, which is more than 3% of the trade value at the top of the curve.

The update was released without formal notice, but checks of archived versions of the document suggest that the payment language is new.

A liquid incentive, not a platform-wide tax.

The quiet release sparked discussion on social media, with community members framing the change as a market structure adjustment rather than a simple fee increase.

X user 0x_opus said the change “increases protection against laundering”, adding that Polymarket “has not started charging users in the usual way” because the fees will be transferred to market makers.

Another trader, kiruwaaaaaaa, described the move as “a crackdown on high-frequency bots,” arguing that fee-backed offers encourage tighter spreads and more consistent liquidity.

User Tawer955 provided a more detailed description of the title, “Scary, but not as bad as it sounds.” He said the system would create a sustainable cash flow for liquidity providers and reduce the incentive for bots that previously used free liquidity.

For most Polymarket users, the impact will be limited. The new fees do not apply to long-term event markets, political markets, or non-crypto forecasts, which remain fee-free.

Even in fee-enabled markets, the structure softens the impact on small or niche businesses. Fees fall dramatically and are reserved for very small transactions.
