Why Did Polymarket Introduce These Fees?

[mendez]

Is this just a fee hike?
Not exactly. Community members have framed the change as a market-structure adjustment, not a platform-wide tax. The goal is to improve liquidity quality rather than generate revenue for Polymarket.

What problem does it solve?
Several traders noted that the fees help discourage wash trading and high-frequency bots that previously exploited free liquidity. Fee-funded rebates encourage more consistent market making and healthier order books.

How much will this affect regular users?
For most users, the impact is minimal. Fees don’t apply to most markets, drop sharply near probability extremes, and are rounded down for small trades. Directional traders and casual users are unlikely to notice major changes.
