Polymarket Maker Strategy: Earning Rebates as Income (2026)

Ahmed Trading· sdk · Updated October 2026

Maker rebates turn Polymarket liquidity provision into a daily income line: taker fees fund a pool, and makers who get filled earn a share of it — 25% of taker fees in politics, finance, tech and most categories, 20% in crypto, 15% in sports, paid every day in pUSD. The strategy is quoting, not predicting: you earn from flow, and your main risks are adverse selection and inventory.

How is the rebate actually computed?

For each filled maker order, Polymarket computes the fee-equivalent your liquidity generated, using the same curve as taker fees:

fee_equivalent = C × feeRate × p × (1 − p)
rebate = (your_fee_equivalent / total_fee_equivalent_in_market) × rebate_pool
Category Rebate share Taker fee rate
Politics, Finance, Tech, Mentions 25% 0.04
Economics, Culture, Weather, Other 25% 0.05
Crypto 20% 0.07
Sports 15% 0.05
Geopolitics — (fee-free, no pool) 0

Payouts are daily, in pUSD, with a $1 minimum accrual. Competition is per-market: you rank only against makers in the same book.

What does a rebate bot do all day?

The core loop on a liquid market:

  1. Quote both sides — bid and ask around your fair value, sized to inventory limits
  2. Refresh on drift — reprice as the underlying signal moves; stale quotes are free money for informed takers
  3. Skew with inventory — after buying, lean the ask; after selling, lean the bid — pulling you back to flat
  4. Respect the fee curve — near-extreme prices (under 10¢, over 90¢) have the fattest fee-equivalents relative to trade value, so those fills earn the most rebate weight
  5. Stay maker — post-only on perps guarantees it; on spot, price inside the spread rather than joining the taker queue

What is the real risk: adverse selection?

Every fill is someone choosing to trade with you at your price. The two-sided pattern:

Your spread is the compensation for meeting both. The discipline that separates income from bleeding: when your signal says the market moved, your quotes move first — the rebate on one stale fill never covers the loss on a repriced position.

What inventory limits make it survivable?

Limit Purpose
Per-market max position One event can’t dominate the book
Per-category cap Correlated markets can’t stack
Max quote size per level One taker can’t fill you to the cap in one print
Flat target Inventory skew decays toward zero on a schedule
Kill threshold Error rate or drawdown pauses quoting

Where does the strategy earn most?

Rebate economics favor: liquid markets with steady two-sided flow (politics near events, crypto majors, sports in season), prices away from 0/100 where the p×(1−p) curve pays, and books thin enough that your size ranks in the rebate pool but deep enough that fills are continuous. Dead markets earn nothing; one-sided runaway markets earn rebates while your inventory drowns.

FAQ

Q: How much can maker rebates earn? A: It scales with filled volume and competition in each market — the pool is 15-25% of that market’s taker fees. On busy books a competent quoter earns a meaningful daily pUSD drip; on thin books, pennies.

Q: When are rebates paid? A: Daily, in pUSD, straight to your wallet — minimum $1 accrued before a payout fires.

Q: Do I need special status to earn rebates? A: No — any maker whose resting order gets filled earns, weighted by the fee value their liquidity generated. The tiered volume system on perps is separate from spot rebates.

Q: Why did I earn a rebate and still lose money? A: Rebates pay for providing liquidity; adverse selection can exceed them. A filled bid on a crashing market earns its 25% share while the position loses multiples of that. Quote discipline and inventory limits are the actual product.

Q: Do geopolitics markets pay rebates? A: No — they’re fee-free entirely, so there’s no taker-fee pool to share. Quote where fees exist.
