Polymarket has enabled taker fees across multiple market categories. These fees fund a **Maker Rebates** program that pays daily USDC rebates to liquidity providers.
Deeper liquidity means tighter spreads, lower price impact, more reliable fills, and greater resilience during volatility. Maker Rebates incentivize **consistent, competitive quoting** so everyone gets a better trading experience.
* **Paid daily in USDC:** Rebates are calculated and distributed every day.
* **Performance-based:** You earn based on the share of liquidity you provided that actually got taken.
### Eligibility
Place orders that add liquidity to the book and get filled (i.e., your liquidity is taken by another trader).
### Payment
Rebates are paid daily in USDC, directly to your wallet.

## Funding
Maker Rebates are funded by taker fees collected in eligible markets. A percentage of these fees are redistributed to makers who keep the markets liquid. The rebate percentage differs by market type.
Rebates are distributed using the **same formula as taker fees**. This ensures makers are rewarded proportionally to the fee value their liquidity generates.
For each filled maker order:
```text theme={null}
fee_equivalent = C × p × feeRate × (p × (1 - p))^exponent
```
Where **C** = number of shares traded and **p** = price of the shares. The fee parameters differ by market type:
Totals are calculated per market, so you only compete with other makers in the same market.

## Taker Fee Structure
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. Fees are highest at 50% probability and lowest at the extremes (near 0% or 100%).
Fees are rounded to 4 decimal places. The smallest fee charged is 0.0001 USDC. Anything smaller rounds to zero, so very small trades near the extremes may incur no fee at all.
The following market categories have taker fees enabled and are eligible for maker rebates: Crypto, Sports, Finance, Politics, Economics, Culture, Weather, Tech, Mentions, and Other / General.
Fees apply only to markets deployed on or after the activation date. Pre-existing markets are unaffected. Markets with fees enabled have `feesEnabled` set to `true` on the market object.
