Polymarket fees: what traders need to know

Polymarket fees are simple but important: maker fees are zero, taker fees vary between 0% and 1.8%, and the Geopolitics category is fee-free. That matters for traders executing frequent fills or running arbitrage. This page explains how fees are charged, where they matter in intra-market arbitrage, and how PolyArb can change your execution economics.

How Polymarket charges fees

Polymarket separates maker and taker roles. Makers who post resting limit liquidity pay no maker fee; takers who consume liquidity pay a variable taker fee that currently ranges from 0% up to 1.8% depending on category.

There are category exceptions: the Geopolitics category is fee-free for takers. Fees apply on the CLOB matching engine and are deducted from trade proceeds; makers benefit from zero maker fees but still face the usual spread and tick-size mechanics.

Why fees matter for arbitrage

Intra-market arbitrage strategies buy multiple complementary outcomes whose best-ask sum is below $1.00. The raw edge equals $1.00 minus that sum, but net edge must account for taker fees, partial fills, and slippage.

Because makers pay zero fees, an arbitrageur that can post and get filled as a maker preserves more of the spread. PolyArb's low-latency routing ($99/month) increases your chance to capture edges as maker or favorable taker fills while the market is live.

Operational limits and other costs

Polymarket sponsors gas via the Relayer, so you don’t pay gas; settlement uses pUSD and the Gnosis CTF for splits/merges/redeems. Watch for tick-size changes ($0.01 or $0.001 near extremes) that affect fills and visible liquidity.

Also consider non-fee risks: UMA resolution disputes, delayed settlement, smart-contract risk, and geo-restrictions that can block new orders in some countries. These affect realized profit even when the arithmetic edge looks clean.

Where PolyArb fits

PolyArb is a non-custodial arbitrage bot priced at $99/month. It offers ~40ms latency vs ~800ms for many free bots, Telegram and Discord alerts, and a stated $7.62 minimum guaranteed edge per trade, all designed to improve execution and reduce missed fills.

PolyArb doesn’t eliminate fees or protocol risks, but lower latency and alerting help you capture more opportunities and convert raw spreads into net profit after taker fees and slippage are considered.

FAQ

What are Polymarket maker and taker fees?
Makers who post resting liquidity pay zero maker fees. Taker fees vary by category and currently range from 0% to 1.8%. The Geopolitics category is fee-free for takers.
Does Polymarket charge gas fees?
No. Polymarket sponsors gas for end users via the Relayer. You still need pUSD to trade and you may incur maker/taker fees depending on your fills.
How do fees affect intra-market arbitrage?
Net arbitrage profit equals the raw edge minus taker fees, partial fills, slippage, and any builder fees if you route through a Builder. Posting as a maker preserves more of the edge because maker fees are zero.
Can PolyArb remove fee impact?
No tool removes protocol fees, but PolyArb’s latency and routing can increase the fraction of opportunities you capture and the likelihood of maker-style fills, improving net returns after fees.
