Frequently asked questions

How does Polymarkets liquidity reward program pay?
Liquidity providers (makers quoting tight spreads) earn a share of taker fees in their markets, typically 20-25% of the fee on every taker order that hits their resting quote. Payments accrue automatically and credit your wallet daily.
What spread do I need to quote to qualify for rewards?
Polymarkets program requires you to quote within a defined band of the mid-price - typically 1-3 cents on each side. The exact threshold varies by market depth; check the markets reward documentation. Quotes outside the band do not earn rebates.
Is liquidity-rewards farming profitable for retail?
Marginally. The rebate alone is ~0.15-0.30% per round trip on liquid markets. Combined with the spread (1-2 cents per round trip), gross returns can be 0.5-1% per round trip - but inventory risk (a 5-cent adverse move costs more than 50 round trips) means most retail farmers lose money on a bad day.
What markets are best for farming?
Liquid politics and sports with consistent two-sided flow but slow news. Bitcoin price markets are too volatile. NegRisk multi-outcome markets often have better farmable spreads because each leg is thinner. Check markets with at least 50K USD in 24h volume and minimal news flow.
How is farming different from full market making?
Farming optimizes for rebate volume; full market making optimizes for spread + rebate. Farming bots quote at the threshold and accumulate volume; MM bots quote tighter and skew with inventory. Farming is more passive - simpler to code, less PnL volatility, lower expected return.
Can I farm rewards while sleeping?
Yes - that is the appeal. A well-coded farming bot only needs intervention if the market shifts by more than your spread tolerance. We have farming bots that run for weeks unattended. The risk is news flow blowing up the inventory while you sleep, which is why hard inventory caps are non-negotiable.
