Polymarket Liquidity Rewards: Daily Payouts for Limit Orders

Polymarket pays traders to provide liquidity. Not through fees. Not through the spread. Through a standalone rewards program that distributes pUSD every day to anyone who parks limit orders near the midpoint price of a market.

These are Polymarket liquidity rewards — the flow of income people usually mean when they say “reward farming.” Everything about the strategy is downstream of one formula and a handful of per-market parameters, and both are published. If you can keep orders resting in the book, close to the midpoint, on both sides of the market, you earn rewards regardless of whether those orders ever get filled.

It sounds straightforward. But the mechanics under the surface — quadratic scoring, two-sided weighting, the $1 payout floor — reward precision. This guide breaks down how the program actually works, how to position yourself for meaningful liquidity rewards, and where the strategy can hurt you.

Liquidity Rewards and the Other Three Programs

Before going further, a critical distinction. Polymarket runs four separate programs that can pay a trader who provides liquidity. They stack, but they are funded and calculated in completely different ways.

1. Liquidity Rewards — pays you for having limit orders in the book near the midpoint. Your orders do not need to be filled. Funded by a per-market allocation. This is what reward farming targets, and it is what the rest of this page is about.

2. Maker Rebates Program — pays you a share of the taker fees your resting orders absorb when they do get filled. It is performance-based and calculated per market: your daily rebate is your share of that market’s total fee-equivalent volume multiplied by the market’s rebate pool (25% of collected taker fees in most categories, 20% in crypto, 15% in sports). Paid daily in pUSD with a $1 minimum accrued. The “Maker Rebate %” column in Polymarket’s fee table is not a discount on your own trades — it is the share of collected taker fees redistributed to makers. This is covered in our Polymarket fees guide.

3. Taker Rebates Program — pays you back on trades where you cross the spread. Maker fills earn nothing here. You accumulate Weighted Volume (wV) on taker trades only, and your rebate percentage is set by your trailing 30-day wV tier. Details below.

4. Holding Rewards — pays 3.25% annualized on the value of positions you hold in eligible markets, sampled once per hour and distributed daily. This one only matters to a reward farmer after a fill, because it applies to position value, not to cash sitting in resting orders.

A resting limit order near the midpoint can therefore earn liquidity rewards for being there, a maker rebate if it gets filled, and holding rewards on whatever position the fill leaves behind. The optimization problems are different for each, which is why it is worth keeping them straight.

How Polymarket Liquidity Rewards Work

Polymarket’s liquidity rewards program is designed to achieve several goals simultaneously: catalyze liquidity across all markets, encourage liquidity throughout a market’s entire lifecycle, motivate passive and balanced quoting tight to the midpoint, encourage trading activity, and discourage blatantly exploitative behavior.

Here is how it operates in practice.

The Scoring Formula, Worked

Every resting limit order is automatically eligible and receives a score based on how close it sits to the midpoint price. The formula is quadratic:

S(v, s) = ((v − s) / v)² × b

Where:

• v = the maximum spread from the midpoint — the market’s cutoff, in price terms. Orders at or beyond this distance score zero.
• s = the spread from the size-cutoff-adjusted midpoint — how far your order actually sits from the middle.
• b = the in-game multiplier. This is not order size. Size enters the calculation separately, through a market’s BidSize and AskSize parameters. If you read elsewhere that b is your order size, that is wrong, and it matters: doubling your order does not simply double your score.

Because the whole expression is squared, the payoff to precision is large, and it is worth seeing the numbers. Take a market with a maximum spread of v = 0.03 (3 cents). Holding b at 1 so you can see the shape of the curve:

Two facts fall straight out of that table. Moving from 2 cents away to 1 cent away — halving the distance — quadruples the score (0.1111 → 0.4444; the ratio is exactly ((0.03 − 0.01) / (0.03 − 0.02))² = 4). And squeezing from 1 cent to half a cent multiplies it by another 1.56×. An order sitting right at the maximum spread is worth nothing at all, because the numerator goes to zero. The curve is steep near the center and flat near the edges, so the last fraction of a cent is worth more than the first.

Size still matters, because a market sets a minimum size cutoff — an order below it scores zero, no matter how tight the placement. And it matters on the other side too: your standing quote size feeds the BidSize and AskSize terms that the market uses, which is the mechanism the old “b is order size” reading was trying to describe.

Two-Sided vs. Single-Sided Quoting

The program strongly favours two-sided liquidity — having orders on both sides of the same market.

When you quote both sides, the system uses min(Q_ne, Q_no) — the smaller of your Yes-side and No-side scores — as your base input. That means an unbalanced book is scored at the level of its weaker leg. Concretely: if your Yes-side order scores 0.4444 and your No-side order scores 0.1111, your input is 0.1111, not the average and not the sum.

When you quote only one side while the midpoint sits between 0.10 and 0.90, your score is divided by a constant c = 3.0. The same single order that scores 0.4444 two-sided is worth just 0.1481 on its own. That is a steep penalty — you need three times the score on one leg to match an equivalent two-sided quote — but it does not shut you out completely.

When the midpoint is outside the 0.10 to 0.90 band — meaning the market is heavily lopsided — liquidity must be double-sided to score at all. Single-sided orders earn nothing in these extreme-probability markets.

The message is clear: Polymarket wants quoters who provide depth on both sides of the book. If you are going to farm liquidity rewards, plan to quote both sides.

Payout Mechanics: Pools, Shares, and the $1 Minimum

Scores accumulate across all participants and all markets, and are settled at midnight UTC, when the system normalizes scores within each market and distributes rewards proportionally:

• Rewards are allocated per market. Each market sets its own daily reward pool and its own allocation. Your share of one market does not help you in another.
• Your payout is your share of the total score in that market, times that market’s pool. If you earned 10% of the total score in a market, you receive 10% of that market’s reward pool for the day.
• Payment is daily at midnight UTC, in pUSD, directly to your maker address.
• Minimum payout is $1. If your share of a market’s pool comes to less than $1, it is not distributed, and it is not carried forward.

That last point is more consequential than it looks, because it converts directly into a share-of-score requirement that scales with the pool:

Run the arithmetic forward and the income picture is clear. If a market’s pool for the day is $500 and you hold 10% of the total score, you are paid $50. At 8%, it is $40. At 0.1% — one part in a thousand against fifteen other equally sized farmers — it is $0.50, which is below the minimum and therefore zero. The pool size you are competing for, and the number of people competing in it, matter as much as the precision of your quotes.

The Four Conditions That Score Zero

This is the part of the program that is rarely written down plainly, and it is where most of the avoidable losses in reward farming live:

1. Your order sits further from the midpoint than the market’s maximum spread (v). The market publishes its own cutoff, and there is nothing to gain by quoting outside it.
2. Your order falls below the market’s minimum size cutoff. A perfectly placed 4-share order scores nothing. Remember that limit orders on Polymarket also require a minimum of 5 shares regardless.
3. The midpoint is outside 0.10 to 0.90 and you are quoting one side only. In extreme-probability markets, single-sided liquidity earns nothing at all — the 1/c penalty does not apply, because there is no score to divide.
4. Your day’s share of the pool is worth less than $1. The order scored; the payout was simply too small to be distributed.

There is no notification for any of these. Your orders still sit in the book, still look like they are working, and quietly earn nothing.

Strategy: Optimizing Your Liquidity Reward Score

The scoring formula creates a clear optimization surface. Here is how to work it.

Get Close to the Midpoint

This is the single biggest lever, and the worked table above quantifies why: at a 3-cent maximum spread, halving your distance from 2 cents to 1 cent quadruples your score. Moving from 1 cent to half a cent multiplies it by 1.56× again.

The practical implication: small improvements in order placement matter. If you can safely tighten your quotes by even a fraction of a cent, the reward payoff is disproportionate.

Quote in a Fine-Tick Market

Placement precision is bounded by the market’s tick size, and ticks vary by market. Of 1,000 sampled Polymarket markets, 583 used a tick of 0.01 and 417 used a tick of 0.001.

Assume a midpoint of exactly 0.500 in a market with a 3-cent maximum spread. On a 0.01-tick market the tightest legal quote is 0.49 or 0.51 — 1 cent away, scoring 0.4444. On a 0.001-tick market you can post 0.499 or 0.501 — a tenth of a cent away, scoring 0.9344. Same order size, same market conditions, same capital: 2.1 times the score, purely because the tick is finer. Before you commit capital to a market, check its tick size.

Always Quote Both Sides

The 3× penalty for single-sided quoting (and outright exclusion when the midpoint is outside 0.10 to 0.90) makes two-sided quoting effectively mandatory for serious reward farming, and because the two-sided input is min(Q_ne, Q_no), balance is what pays. Structure your capital to post orders on both sides of a market.

This does not mean your two quotes must be symmetrical — you can quote tighter on one side and wider on the other. But the weaker side is the one that sets your score, so a lopsided book wastes the better leg. Improving your 0.1111 side to 0.4444 raises your input by four times; improving the 0.4444 side does nothing until it passes the other.

Size Matters, But Placement Matters More

Because b is a market’s in-game multiplier rather than your order size, you cannot simply double your order and expect double the score. What size does buy you is the ability to clear the market’s minimum size cutoff — below which you score zero — and to satisfy the market’s BidSize / AskSize terms. Check both parameters for any market you are considering before deploying capital.

The spread term, by contrast, is quadratic: halving your distance from the midpoint more than quadruples that component of the score. Placement dominates size.

Choose Your Markets Carefully

Reward pools vary by market, and so does the competition. The ratio of the reward pool to the number of active participants determines how much each farmer can realistically earn.

Look for markets where:

• The pool is meaningful relative to the number of competitors — check the share-of-score you would need to clear $1 and make sure you can plausibly hold more than that.
• The midpoint is relatively stable (less frequent re-quoting needed)
• The midpoint sits between 0.10 and 0.90 (so single-sided quoting is at least possible as a fallback)
• The tick size is fine enough to place quotes close to the midpoint
• Volatility is manageable (lower risk of adverse fills)

Avoid markets approaching a known catalyst — an election result, an earnings announcement, a deadline — where the price is likely to gap through your orders.

Monitor and Re-Quote

Scores accrue from the state of the book over time rather than being captured at a single instant, so stale orders cost you: if the midpoint moves and your orders are now further away, your score drops for as long as they sit there. Active monitoring and re-quoting keeps your orders positioned where they score highest.

This does not mean you need to watch continuously. But checking your positions a few times a day — or scripting order management through the Polymarket CLOB API — makes a meaningful difference versus purely passive order placement. Cancelling and replacing a resting order is fee-free, so re-quoting costs you nothing except the moment your capital is out of the book.

Order Mechanics That Set Your Floor

Three platform rules constrain every liquidity-rewards strategy, and all three have a numeric edge you should know:

• $1 USD minimum order value. You cannot post a $0.50 order to farm rewards cheaply.
• Limit orders require a minimum of 5 shares. Market orders can be smaller, but every order you rest in the book is a limit order and therefore subject to the 5-share floor. Your real minimum capital per quote is 5 × the price you are quoting — at $0.50 that is $2.50 per side, $5.00 for a two-sided quote, before any meaningful size.
• Matching is off-chain, settlement is on-chain. The order book is hybrid. Cancelling is fast in the matching layer, but a market can move between your decision and the cancel landing — which is exactly the window in which adverse fills happen.

The Core Tension: Rewards vs. Fill Risk

Here is where reward farming gets difficult.

The scoring system pays you the most for orders placed as close to the midpoint as possible. But the midpoint is where the market trades. Orders close to the midpoint are the most likely to be filled.

When your limit order gets filled, you acquire a position. That position has directional exposure. If the market moves against you after the fill, you lose money. This is adverse selection — your order tends to get filled precisely when the market is moving away from your entry price, because informed traders are taking the other side.

Put numbers on the trade-off. Suppose you are quoting a bid at 53 cents for 100 shares of a market and news breaks that takes the fair value to 2 cents. Your loss on that fill is (0.53 − 0.02) × 100 = $51.00. In the same market, a $500 daily pool where you hold 10% of the score pays $50.00 per day. One adverse fill erases an entire day of rewards — and the order that got filled was, by construction, the one closest to the midpoint, which is precisely the one the scoring formula paid you most to place.

The tension is real and unavoidable:

• Tight quotes = high reward scores, high fill risk, high adverse selection exposure
• Wide quotes = low reward scores, low fill risk, orders mostly sit untouched

There is no universally correct answer. The right placement depends on the specific market’s volatility, the size of the reward pool, and your risk tolerance. In stable, slow-moving markets with large reward pools, tighter quotes may be justified. In volatile markets approaching a catalyst, wider quotes — or no quotes at all — may be the better call.

This is the same risk-reward calculation that professional market makers face, except reward farmers have an additional income stream (the rewards themselves) that subsidizes the cost of adverse fills.

The Other Income on the Same Capital

Because liquidity rewards are separate from the other three programs, it is worth knowing exactly what else your resting capital is and is not earning.

When an order fills, you earn a maker rebate. The rebate is weighted by the same fee curve as the taker fee — fee_equivalent = C × feeRate × p × (1 − p) — and calculated per market. In a politics market at 50 cents, 100 shares of taker flow generates $1.00 of fee, of which the 25% rebate pool is $0.25. In crypto the numbers are larger per share ($1.75 of fee on 100 shares at 50 cents, 20% rebate share); in sports they are smaller ($1.25 of fee, 15% rebate share). Paid daily in pUSD with a $1 minimum.

When you unwind a filled position by crossing the spread, you earn Weighted Volume toward Taker Rebates:

wV = Trade Size × (1 − Entry Price) × Category Weight

Category weights are Sports 1.0 · Politics/Finance/Mentions/Tech 1.3 · Economics/Culture/Weather/Other 1.7 · Crypto 2.3 · Geopolitics 0. Tiers run from Bronze at $2,000 of trailing 30-day wV (3% rebate) to Obsidian at $10,000,000+ (50%), recalculated daily at midnight UTC and applied going forward only — nothing is backfilled. For scale: 1,000 shares entered at $0.60 in a politics market earns 1,000 × (1 − 0.60) × 1.3 = 520 wV; the same 1,000 shares at $0.20 in an economics market earns 1,000 × 0.80 × 1.7 = 1,360 wV. Reaching even the $2,000 Bronze threshold takes roughly 3,847 shares at $0.60 in politics. Note that your maker fills earn no wV at all — only the taker side of your activity counts.

Filled positions earn holding rewards. Polymarket pays 3.25% annualized on total position value in eligible markets, sampled once per hour and distributed daily. The rate is variable and set at Polymarket’s discretion. Cash sitting in an unfilled resting order does not earn it; position value does.

And one thing your capital is not earning: anything, in markets with no fee pool. Geopolitics markets collect no taker fees, so there is no rebate pool to be distributed there. Liquidity rewards are a separate per-market allocation, so do not assume the two always appear together — check each market’s own parameters.

Risks and Realistic Expectations

Adverse Fills

Your orders will get filled. Not every day, but regularly. When they do, you are left with a directional position that you may not want. If you are quoting both sides, fills on one side create inventory that partially offsets — but only partially. Managing accumulated positions is part of the strategy.

Resolution Risk

If a market resolves while you hold a position accumulated through fills, that position pays out at $1.00 or $0.00. There is no gradual unwinding. If you bought Yes shares through fills and the market resolves No, those shares go to zero.

Competition

Liquidity rewards are normalized across all participants in a market. As more farmers enter a market, the same pool gets split more ways. Early entrants to a new market may earn outsized rewards; crowded markets produce thin returns per participant — and when your share falls below the $1 minimum, the return is zero rather than thin.

Below-Minimum Days Are Real

Because each market is scored and paid separately with a $1 floor, a diversified farming book produces a patchwork of outcomes: one market pays, another does not, and nothing carries over. Do not model liquidity rewards as a stable daily income. Model them per market, against that market’s pool.

Capital Is Locked

Your pUSD is tied up in resting limit orders. It cannot be deployed elsewhere while it sits on the book, and cash in an unfilled order is the one form of capital that earns none of the four programs. Factor in this opportunity cost against alternatives — stablecoin lending, bonding near-certain outcomes, or holding positions that qualify for holding rewards.

Practical Walkthrough

Here is how to approach reward farming step by step.

1. Set up your account. You need a Polymarket account with pUSD deposited to your trading wallet.

2. Check market parameters. Use the CLOB API to fetch each market’s maximum spread, minimum size cutoff, reward allocation, and tick size. These four numbers define the playing field — orders beyond the maximum spread or below the minimum size earn zero, and the tick bounds how tight your quotes can actually be.

3. Identify the midpoint. The midpoint price is the reference point for scoring. Note where it sits, whether it sits inside the 0.10 to 0.90 band, and how volatile it has been recently.

4. Place two-sided orders. Post limit orders on both sides, as close to the midpoint as your risk tolerance allows, remembering that limit orders need at least 5 shares and your score is set by the weaker of the two sides.

5. Monitor fills and re-quote. If the midpoint drifts, your orders drift with it in terms of distance — and your score drops for as long as they sit there. Re-quote to stay tight; cancelling and replacing is free. If orders get filled, decide whether to re-post at the new midpoint or manage the resulting position.

6. Collect rewards daily. Rewards hit your maker address at midnight UTC, in pUSD, per market, with a $1 minimum per market. Track which markets actually paid — a market that consistently falls below the minimum is a market where your capital is doing nothing.

7. Evaluate net P&L. Reward farming profitability is not just reward income. It is reward income, plus maker rebates on fills, plus holding rewards on resulting positions, minus losses from adverse fills, minus the opportunity cost of locked capital. Track all of it.

Liquidity Rewards vs. Market Making

Reward farming and market making overlap substantially. Both involve resting limit orders on both sides of the book. Both expose you to adverse selection. Both reward tighter quotes.

The key difference is the objective function:

• Market makers optimize for the spread — the gap between their bid and offer. Filled orders are the goal, because each fill captures a small profit.
• Reward farmers optimize for the reward score — keeping orders in the book near the midpoint. Filled orders are a side effect to be managed, not the primary income source.

In practice, the two strategies blend naturally. A market maker on Polymarket also earns liquidity rewards for the same orders that generate spread income. A reward farmer who occasionally gets filled also earns maker rebates and can capture the spread. You do not have to choose one or the other.

Where they diverge is in how you handle fills. A pure market maker actively manages inventory and tries to offset positions. A pure reward farmer may prefer to re-post orders and accept small position accumulation, focusing on keeping the score high rather than managing every fill.

Key Takeaways

Polymarket’s liquidity rewards program pays you for providing liquidity — not for trading, not for being right, but for keeping orders in the book near the midpoint. The scoring system is quadratic, so precision is worth far more than size. Two-sided liquidity is strongly preferred, and in markets whose midpoint sits outside 0.10 to 0.90, it is required.

The strategy is accessible. You do not need to be a quantitative trader or run automated infrastructure. But it is not free money. The orders that score highest are also the most likely to get filled, and fills carry real directional risk — one news event can erase a day of rewards. The best reward farmers manage this tension deliberately: tight enough to score well, wide enough to avoid getting consistently run over, and honest about which markets are paying them at all.

Used alongside maker rebates and an understanding of how Polymarket’s order book works, liquidity rewards are a meaningful tool in the Polymarket trader’s toolkit.
