<Update label="Mar 17, 2026" description="March Madness: $2M+ in Liquidity Rewards">
* **March Madness Liquidity Rewards**: Adding \$2M+ in liquidity rewards to both live and pregame markets.
* **How it works**: Liquidity rewards are payments for placing competitive bids. Rewards are paid out based on the size of your orders, how close they are to the midpoint, and how consistently they are quoted relative to other liquidity providers. Orders must be active on the book for a minimum of **3.5 seconds** to be eligible.
**Daily reward rates for markets (subject to change):**
**48 hours before GameStartTime:**
* \$7.5k for full game ML market
* \$500 for 5 other markets (most recently created full game spread, most recently created full game total, 1st half ML, most recently created 1st half spread, most recently created 1st half total)
**From game live to game completion (note: rewards are expressed in daily rates):**
* \$60k for full game ML
* \$4k for most recently created full game spread and most recently created full game total
**From game live to halftime (note: rewards are expressed in daily rates):**
* \$8k for 1st half ML, most recently created 1st half spread, most recently created 1st half total
* **Markets**: [Browse March Madness markets](https://polymarket.com/sports/cbb/games)
* **More details**: [Liquidity Rewards documentation](/market-makers/liquidity-rewards#liquidity-rewards)
</Update>
<Update label="Mar 1, 2026" description="Taker Fees & Maker Rebates: All Crypto Markets">
* **Crypto market fees expansion**: Starting March 6, 2026, taker fees and maker rebates extend to all crypto markets including 1H, 4H, daily, and weekly. The same fee structure as existing crypto markets applies. Only new markets created after March 6 are affected.
* **Updated documentation**: [Fees](/trading/fees) and [Maker Rebates Program](/market-makers/maker-rebates) updated to reflect all crypto market coverage.
</Update>
<Update label="Feb 12, 2026" description="5-Minute Crypto Markets">
* **5-minute crypto markets**: Launched with taker fees enabled. Fees follow the same curve as 15-minute crypto markets, peaking at 1.56% at 50% probability.
* **Maker Rebates**: Liquidity providers earn daily USDC rebates funded by taker fees, same as 15-minute crypto markets.

> Earn daily USDC rebates by providing liquidity on Polymarket
Polymarket has enabled taker fees on **15-minute crypto markets**, **5-minute crypto markets**, **NCAAB (college basketball)**, and **Serie A** markets. These fees fund a **Maker Rebates** program that pays daily USDC rebates to liquidity providers.
Polymarket has enabled taker fees across multiple market categories. These fees fund a **Maker Rebates** program that pays daily USDC rebates to liquidity providers.

## Why Maker Rebates?
## Why Maker Rebates
Sports markets benefit from the same dynamics as crypto markets. When liquidity is deeper:
* Spreads tend to be tighter
* Price impact is lower
* Fills are more reliable
* Markets are more resilient during volatility
Maker Rebates incentivize **consistent, competitive quoting** so everyone gets a better trading experience.

> Understanding trading fees on Polymarket
Polymarket does not charge fees on most markets. However, certain markets have taker fees enabled to fund the [Maker Rebates Program](/market-makers/maker-rebates).
Polymarket charges a small taker fee on certain markets. These fees fund the [Maker Rebates Program](/market-makers/maker-rebates), which redistributes fees daily to market makers to incentivize deeper liquidity and tighter spreads.
**Geopolitical and world events markets are fee-free.** Polymarket does not charge fees or profit from trading activity on these markets. There are also no Polymarket fees to deposit or withdraw USDC (though intermediaries like Coinbase or MoonPay may charge their own fees).
<Note>
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.

### Fee Structure
Fees are calculated using the following formula:
```text theme={null}
fee = 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:

| -------------- | ----------------------- | --------------------- |
| Fee Rate | 0.0175 | 0.25 |
| Exponent | 1 | 2 |
| Maker Rebate % | 25% | 20% |
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. The effective rate **peaks at 50%** probability and decreases symmetrically toward the extremes.
