What did Polymarket update?

[mendez]

Polymarket updated its documentation to show that 15-minute crypto up/down markets now include taker fees, marking a shift from its long-standing zero-fee model.

Does this apply to all Polymarket markets?
No. The change applies only to short-duration 15-minute crypto markets. The vast majority of Polymarket markets—including political, long-term event, and non-crypto markets—remain completely fee-free.

Was there an official announcement?
No formal announcement was made. The update was discovered through changes to Polymarket’s “Trading Fees” and “Maker Rebates Program” documentation, which did not previously reference these fees.

15-minute markets having fees makes sense but kinda kills the fun a bit
