# Maker Rebates Program

> Technical guide for handling taker fees and earning maker rebates 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.

<Note>
  Starting **Wednesday, February 18th, 2026 at midnight (UTC)**, taker fees and maker rebates will apply to all **new** NCAAB and Serie A markets created after that time. Existing markets are not affected. The first payout will be on February 19th at midnight (UTC).
</Note>

## Fee Handling by Implementation Type

### Option 1: Official CLOB Clients (Recommended)

The official CLOB clients **automatically handle fees** for you

<Card title="TypeScript Client" icon="js" href="https://github.com/Polymarket/clob-client">
  npm install @polymarket/clob-client\@latest
</Card>

<CardGroup cols={2}>
  <Card title="Python Client" icon="python" href="https://github.com/Polymarket/py-clob-client">
    pip install --upgrade py-clob-client
  </Card>

  <Card title="Rust Client" icon="rust" href="https://github.com/Polymarket/rs-clob-client">
    cargo add polymarket-client-sdk
  </Card>
</CardGroup>

**What the client does automatically:**

1. Fetches the fee rate for the market's token ID
2. Includes `feeRateBps` in the order structure
3. Signs the order with the fee rate included

**You don't need to do anything extra**. Your orders will work on fee-enabled markets.

***

### Option 2: REST API / Custom Implementations

If you're calling the REST API directly or building your own order signing, you must manually include the fee rate in your signed order payload.

#### Step 1: Fetch the Fee Rate

Query the fee rate for the token ID before creating your order:

```bash  theme={null}
GET https://clob.polymarket.com/fee-rate?token_id={token_id}
```

**Response:**

```json  theme={null}
{
  "fee_rate_bps": 1000
}
```

* **Fee-enabled markets** return a value like `1000`
* **Fee-free markets** return `0`

#### Step 2: Include in Your Signed Order

Add the `feeRateBps` field to your order object. This value is part of the signed payload, the CLOB validates your signature against it.

```json  theme={null}
{
  "salt": "12345",
  "maker": "0x...",
  "signer": "0x...",
  "taker": "0x...",
  "tokenId": "71321045679252212594626385532706912750332728571942532289631379312455583992563",
  "makerAmount": "50000000",
  "takerAmount": "100000000",
  "expiration": "0",
  "nonce": "0",
  "feeRateBps": "1000",
  "side": "0",
  "signatureType": 2,
  "signature": "0x..."
}
```

#### Step 3: Sign and Submit

1. Include `feeRateBps` in the order object **before signing**
2. Sign the complete order
3. POST to `/order` endpoint

<Note>
  **Important:** Always fetch `fee_rate_bps` dynamically, do not hardcode. The fee rate varies by market type and may change over time. You only need to pass `feeRateBps`
</Note>

See the [Create Order documentation](/developers/CLOB/orders/create-order) for full signing details.

## Fee Behavior

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:

| Parameter      | Sports (NCAAB, Serie A) | 5-Min & 15-Min Crypto |
| -------------- | ----------------------- | --------------------- |
| 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.

## Maker Rebates

Your rebate for each market:

```text  theme={null}
fee_equivalent = C × p × feeRate × (p × (1 - p))^exponent
rebate = (your_fee_equivalent / total_fee_equivalent) * rebate_pool
```

### How Rebates Work

* **Eligibility:** Your orders must add liquidity (maker orders) and get filled
* **Calculation:** Proportional to your share of executed maker volume in each eligible market. Totals are calculated per market, so you only compete with other makers in the same market
* **Fee collection:** Fees are calculated in USDC but collected in shares on buy orders and USDC on sell orders
* **Payment:** Daily in USDC, paid directly to your wallet

### Rebate Pool

Each market's rebate pool is funded by taker fees collected in that market. The payout percentage is subject to change:

| Market Type             | Period        | Maker Rebate | Distribution Method |
| ----------------------- | ------------- | ------------ | ------------------- |
| 15-Min Crypto           | Jan 19, 2026+ | 20%          | Fee-curve weighted  |
| 5-Min Crypto            | Feb 12, 2026+ | 20%          | Fee-curve weighted  |
| Sports (NCAAB, Serie A) | Feb 18, 2026+ | 25%          | Fee-curve weighted  |

The rebate percentage is at the sole discretion of Polymarket and may change over time.

***

## Which Markets Have Fees?

The following market types have fees enabled:

* **15-minute crypto markets**
* **5-minute crypto markets**
* **NCAAB (college basketball) markets** (starting February 18, 2026 for new markets)
* **Serie A markets** (starting February 18, 2026 for new markets)

Query the fee-rate endpoint to check any specific market:

```bash  theme={null}
GET https://clob.polymarket.com/fee-rate?token_id={token_id}

# Fee-enabled: { "fee_rate_bps": 1000 }
# Fee-free:    { "fee_rate_bps": 0 }
```
