Polymarket Liquidity Rewards: How They Work

Polymarket liquidity rewards are daily cash payments made by the exchange to traders whose limit orders rest close to a market's midpoint. Each eligible market has its own daily reward pool, and that pool is divided between makers in proportion to how well and how long their orders were positioned during the UTC day.

The programme exists because prediction markets are only useful when someone is willing to trade. A market with no resting orders has nothing to click on. Rather than hope makers show up, the exchange pays for the service directly. Polymarket documents the programme and its parameters publicly; this page describes the mechanism in general terms rather than reproducing their rules, which can change.

The reward pool

Reward-eligible markets carry a daily pool, a fixed amount of money allocated to that market for that day. Pool sizes differ by market and the exchange sets them. Two consequences follow immediately, and they drive most of the strategy in reward farming:

• The pool is fixed, so your share depends on everyone else. A large pool contested by many makers can pay less than a small pool almost nobody is quoting. Reward density, meaning pool size relative to competition, matters more than pool size alone.
• Rewards do not scale with your capital the way interest does. Doubling the money in one market does not double your reward from that market. More capital mostly buys presence in more markets.

Which orders qualify

Not every order earns. An order has to be a resting limit order that someone could actually trade against, and it has to sit within a defined maximum spread of the market's midpoint. Outside that band it earns nothing at all, no matter how long it rests.

There is also a minimum size. Orders below it are ignored for scoring purposes, which is why reward-focused makers tend to quote at or near the minimum: past that threshold, extra size mostly buys extra risk rather than extra reward.

How orders are scored

Three factors decide what a qualifying order earns:

1. Distance from the midpoint. Scoring rewards tighter quotes more than looser ones, and the relationship is non-linear, so an order twice as close is worth considerably more than twice as much.
2. Time. Scoring is sampled through the day, so an order earns for every interval it is resting in the band. A quote that is present all day beats a better quote that is present for an hour. This is the single biggest reason reward farming is automated: uptime is the dominant term, and software does not sleep.
3. Two-sided presence. Quoting both YES and NO at qualifying size earns a multiplier over quoting one side. A maker offering both sides is genuinely making a market rather than working a directional order.

Notably, queue position is not part of the reward score. An order resting behind a deep queue at the same price scores the same as one at the front, while being far less likely to be filled. That asymmetry is the structural feature reward farmers build around.

When payouts settle

Scoring covers the UTC day and payouts settle once nightly at 00:00 UTC, arriving as cash in the maker's account. Because a payout lands the morning after the day it covers, a night's payout reflects the previous day's quoting, which matters when you line rewards up against the costs incurred earning them.

Separately, Polymarket pays maker rebates funded from taker fees. These arrive as their own activity type and are easy to miss when totalling income; our own accounting understated results until they were included.

What it costs to earn them

A qualifying order is a real order. When someone trades against it you own a real position, and unwinding that position has a cost. The traders most eager to hit a resting order are often the better informed ones, so fills cluster exactly when they are most expensive.

This is why a reward figure on its own says very little. Over a recent fifteen-day window our own account earned reward income that was fully offset by the cost of unwinding filled inventory, leaving it net negative. The rewards were real and so were the costs. Both are published on our live results page, and the rules behind those figures are in our measurement methodology.
