How does Polymarket make money: a concise guide
Polymarket primarily earns revenue through trading fees and its Builder Program. Taker fees vary by category (currently between 0% and 1.8%) while maker fees are zero. Polymarket also sponsors gas via its Relayer and exposes builder fees for third parties; these mechanics underpin how traders and builders interact with the platform.
Taker fees and the order book
Polymarket runs a Central Limit Order Book (CLOB). When someone removes liquidity (a taker), Polymarket charges a variable taker fee; maker fees are zero. The taker fee percentage depends on the market category and can be as high as 1.8% in some categories and 0% for fee-free categories like Geopolitics.
The Builder Program and routing fees
The Builder Program lets third parties route orders through the CLOB with attribution headers and earn builder fees in basis points. Builders can also qualify for tiered benefits (Unverified, Verified, Partner), including daily relayer limits and rewards. Polymarket receives a portion of trading volume that flows through this program, aligning incentives between builders and the exchange.
Relayer costs, gas sponsorship, and operational overhead
Polymarket sponsors on-chain gas via a Relayer (a Gas Station Network model), covering wallet deployment, approvals, CTF operations, and order placement for users. Sponsoring gas is an operational expense that Polymarket covers to reduce friction; revenue from fees and builder arrangements helps offset these costs. The platform also integrates with the Gnosis CTF and UMA for settlements and resolution.
Where arbitrage and tools like PolyArb fit
Arbitrageurs capture spreads created by order-book inefficiencies; Polymarket's fee structure and tick sizes influence those opportunities. PolyArb is a paid tool ($99/month) that targets intra-market arbitrage on Polymarket with low 40ms latency, Telegram and Discord alerts, and a claimed $7.62 minimum guaranteed edge per trade. It is non-custodial and designed to execute faster than free bots, but users must consider fees and execution risk.
Risks and limits you should know
Never treat a captured spread as unconditionally risk-free. Resolution risk (UMA disputes), slippage and partial fills, fee changes, settlement timing, and smart-contract risk all affect realized results. Geographic restrictions and Polymarket's terms also limit who can place new orders; never bypass those restrictions with VPNs, which would violate Polymarket's Terms of Service.

FAQ
- Does Polymarket make money from gas fees?
- No. Polymarket sponsors gas for users via its Relayer; gas is an operational cost, not a revenue line for traders.
- What are the main revenue sources for Polymarket?
- The documented sources are variable taker fees across market categories and fee-sharing via the Builder Program. Maker fees are zero.
- How do builder fees work?
- Builders route orders through the CLOB with attribution headers and earn basis-point fees. The Builder Program has tiers (Unverified, Verified, Partner) with different relayer limits and rewards.
- Will fees erase arbitrage profits?
- Fees reduce gross spreads; successful arbitrage requires accounting for taker fees, potential partial fills, and settlement timing. Tools with lower latency and guaranteed edge claims, like PolyArb, aim to improve execution but do not remove resolution and execution risks.
