Polymarket Maker Strategy: Earning Rebates as Income (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:
- Quote both sides — bid and ask around your fair value, sized to inventory limits
- Refresh on drift — reprice as the underlying signal moves; stale quotes are free money for informed takers
- Skew with inventory — after buying, lean the ask; after selling, lean the bid — pulling you back to flat
- 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
- 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:
- Uninformed flow (retail bets, event tourists) — profitable to make against
- Informed flow (news traders, bot alpha) — picks off stale quotes
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.
