Liquidity rewards on Polymarket: how makers get paid

A prediction market only works if there is something to trade against. Someone has to sit on a YES bid at 42¢ and a NO ask at 59¢ so the next person who wants a position can hit either side without slipping 10¢. The traders who post those resting orders are makers. The traders who hit them are takers. On a thin book, few traders quote at all.

If you run a market-making strategy, the reward is your floor. It pays you for being available to be traded against, and it is separate from your trade P&L, which is whatever your fills and your inventory do on top of it.

Each Polymarket reward market publishes 3 numbers a maker has to satisfy: the reward rate per day in USDC, the maximum spread allowed in cents, and the minimum order size in shares. If your resting order sits inside the max spread and at or above the min size, you accrue a share of the daily pool while it stays there.

The pool is divided each day across qualifying orders by a competitive scoring formula. The closer your quote sits to the midpoint, and the more time it spends quoted at qualifying size, the larger your slice. A 50-share resting bid 2 ticks off mid earns less than a 200-share bid 1 tick off mid that has been live for the full day.

The market page on Polymarket shows the per-day reward, the max spread, the min size, and a small bar that indicates how much of the daily pool you are currently capturing. Most markets pay $1 to $50 a day. Outliers like peace deal questions and election event markets in season can pay $500 a day or more.

Cost of capital is first. Reward eligibility requires resting orders, and resting orders tie up capital that could be earning yield somewhere else. A 200-share bid at 42¢ commits $84 of USDC for the duration. If the program pays $5 a day and the market is open for 10 days, the reward is $50 against $84 of locked capital. That is a real return, on capital that is tied up the whole time.

Inventory risk is next. The whole reason you post resting orders is that they get filled. If your YES bid at 42¢ fills and the market drifts to 35¢ before you can re-quote, the 7¢ move costs you $14 on a 200-share fill. The program reward did not save you from a directional miss. Most maker programs assume you have a way to hedge or unwind inventory, rather than that you are happy to be long whatever the order book gives you.

The reward is a floor under a market-making strategy that already works. If you cannot hold inventory or cannot re-quote inside the max spread, the reward will not cover the loss.

The page at 0xinsider.com/liquidity-rewards lists Polymarket reward markets in a single feed. Each row shows the market, its probability, 24-hour volume, liquidity, daily reward, max spread, min shares, and end date, when the provider supplies them.

Sort by Top reward to find the highest-paying programs. Sort by Ending soon for programs about to expire, useful if you want to stack a final-day position into the pool. Sort by Most traded for programs on markets with real flow, where reward eligibility overlaps with real trade P&L.

The feed refreshes every 5 minutes. Use the rewards explorer as a screening tool, then verify the current reward settings and order book on Polymarket before placing an order.
