Polymarket Liquidity Rewards (2026): How Maker Rebates Work

How do Polymarket liquidity rewards work?

Polymarket wants deep, tight order books, so it pays makers for providing them. Any resting limit order within a market's maximum spread and above its minimum size earns a score. Each epoch is one UTC day, and the book is sampled once a minute at a random moment, up to 1,440 samples a day. At each sample your score is compared with every other maker in that market, the shares are summed over the day, and the market's daily reward is split by those shares. Rewards go straight to your maker address at midnight UTC.

The scoring rule is quadratic in distance from the midpoint:

S(v, s) = ((v - s) / v)^2 * b

v = the market's maximum qualifying spread
s = your order's distance from the midpoint
b = the market's in-game multiplier

Why does two-sided liquidity matter?

The score looks at both sides of the market and its complement, and favors makers who quote both. When the midpoint is between 0.10 and 0.90, a single-sided order still scores, but its score is divided by a scaling factor that Polymarket lists as 3.0 on all markets. Outside that range, near the extremes, only two-sided liquidity earns rewards.

How do Polymarket maker rebates work?

Makers on Polymarket pay no fees; only takers do. A share of those taker fees is paid back to the makers whose orders were filled, market by market:

rebate = (your_fee_equivalent / total_fee_equivalent) * rebate_pool
fee_equivalent = C * feeRate * p * (1 - p)

Rebates are paid daily in pUSD, with a $1 minimum, and Polymarket can change the percentages. The fee side is covered in Polymarket fees explained.

How do you find which markets pay liquidity rewards?

The market reward settings are public. This Node 18+ script pages through incentivized markets and ranks them by daily reward; personal earnings use separate authenticated endpoints:

// Polymarket liquidity rewards: every incentivized market, ranked by daily reward
const all = [];
let cursor = '';
do {
  const url = `https://clob.polymarket.com/rewards/markets/current${cursor ? `?next_cursor=${cursor}` : ''}`;
  const page = await (await fetch(url)).json();
  all.push(...page.data);
  cursor = page.next_cursor;
} while (cursor && cursor !== 'LTE=');

all.sort((a, b) => b.total_daily_rate - a.total_daily_rate);
console.log(all.length, 'markets with rewards; total per day', all.reduce((s, m) => s + m.total_daily_rate, 0).toLocaleString());
for (const m of all.slice(0, 5)) {
  console.log(m.condition_id.slice(0, 12), '| per day', m.total_daily_rate, '| max spread', m.rewards_max_spread, '| min size', m.rewards_min_size);
}

How do you track liquidity reward earnings with the API?

Polymarket separates public market configurations from authenticated account reports. The current CLOB API specification documents these read endpoints:

These account and order checks require signed CLOB L2 authentication headers. A public wallet address alone does not authorize them. Use the maker-address and signature-type parameters documented for your account, and keep credentials on your server. Follow next_cursor on paginated earnings reports until the terminal cursor LTE=. Track the UTC date, market, reported earnings and reward share separately; an advertised market reward pool is not your personal payout. Liquidity reward reports and the maker rebate program are separate concepts.

Is market making on Polymarket worth it?

Rewards and rebates can offset spread risk, but they do not remove it. A resting order can be filled just before news moves the price against you, and rewards split across every maker in a market, so the busiest markets are also the most competitive. Returns are potential, never certain. To quote across venues as well as Polymarket, the Predictefy API streams normalized order books from 15+ venues in one shape.
