Polymarket Fees Explained (2026): Every Cost and How to Minimize Them
Polymarket's fees in 2026: the maker/taker split, category taker fees, gas, spreads, and price impact. Every cost explained, and the playbook for minimizing them.
The Short Answer
Polymarket's fee model in 2026: maker orders (resting limit orders) trade free and earn a share of the daily rebate pool, while taker fees apply on most market categories after a rollout through early 2026. Taker fees scale with price and bite hardest at 50 cents, topping out between 1 and 1.75 cents per share depending on the category; geopolitics and world events markets were still fee-free at the time of writing. The standard app flow is gasless; gas only matters for API traders and on/off-ramp transfers, and Polymarket charges nothing to deposit or withdraw. Rates move, so confirm against the official fee schedule before sizing a strategy.
Polymarket fees went from a one-word answer ("none") to a real topic in 2026: taker fees rolled out category by category in the first months of the year, starting with short-term crypto markets and covering nearly everything by late March, while maker orders stayed free. The April CLOB V2 upgrade then rebuilt how those fees are charged. For anyone trading thin edges, the fee structure now decides which trades are worth making at all. This guide explains every cost in the system, how to minimize them, and the fee mistakes that quietly eat accounts.
Key Takeaways
- The big split is maker vs taker: resting limit orders that add liquidity trade free, while instant market orders pay the category's taker fee. Patience is literally free money.
- Fees aren't the only cost: the spread you cross, price impact on thin books, and (for API traders transacting from their own wallets) Polygon gas all subtract from the same edge.
- Fee schedules change, and they did in 2026, so strategies with thin margins should re-verify the official schedule regularly rather than trusting any article's snapshot, including this one.
Every Cost in the System
| Cost | When it applies | How to think about it |
|---|---|---|
| Taker fees | Market orders on fee-enabled categories | The headline cost; 0.04 to 0.07 by category |
| Maker fees | Resting limit orders | Free: the core fee-minimization lever |
| Polygon gas | Direct contract interaction (API/bots), on/off-ramp transfers | Tiny on Polygon; the standard app flow is gasless |
| Spread | Every trade that crosses the book | Not a "fee," but the same money |
| Price impact | Orders bigger than nearby book depth | The invisible cost that dwarfs fees on thin markets |
Maker vs Taker: The Split That Matters
Since fees arrived in early 2026, Polymarket's philosophy is simple: it rewards liquidity and charges impatience. Place a resting limit order that sits on the book, and when it fills you've traded as a maker: free, and on fee-enabled categories makers actually earn rebates funded by taker fees. Smash the buy button at the current price and you've traded as a taker, paying the category's fee on fee-enabled markets. The practical consequence: any strategy that can wait should wait. A limit order a cent inside the market can fill quickly on active markets, and the fee saved is pure edge. On a thin arbitrage or value trade it is frequently the entire edge.
One nuance: fees apply per category, not uniformly. Each category has its own coefficient, and the charge works out to that coefficient multiplied by the share price, by (1 - price), and by the number of shares. The effect is a fee that is symmetric around 50 cents and shrinks toward the extremes, so a contract trading at 3 cents costs almost nothing to take. Here is where the categories sat when we checked in August 2026:
| Category | Taker coefficient | Peak cost at 50 cents |
|---|---|---|
| Crypto | 0.07 | 1.75 cents per share |
| Sports, economics, culture, weather, other | 0.05 | 1.25 cents per share |
| Politics, finance, tech, mentions | 0.04 | 1 cent per share |
| Geopolitics and world events | 0 | No fee |
Makers pay zero in every category and split the taker revenue through the Maker Rebates Program, which pays out daily at 15% to 25% of fees depending on the category. Geopolitics, having no fees to redistribute, has no rebate. Both the category assignments and the coefficients have moved more than once since launch, so treat that table as a snapshot rather than a constant, and check the official fee page before you build anything around a specific number.
The Crypto Costs: Gas and pUSD
Polymarket settles onchain, but in the standard app flow you don't pay gas: Polymarket's relayer covers transaction fees for trades and redemptions, and an Auto-Redeem setting claims winnings from resolved markets automatically. Gas becomes your cost in two cases: interacting with the contracts directly from your own wallet, which is common for API and bot traders, and network fees when moving funds on or off Polygon. Individually these are small (Polygon is a cheap chain), but they're real line items for programmatic traders. Related setup note: since V2, trading collateral is pUSD, a 1:1 USDC-backed token your deposit converts into automatically; the details for programmatic users are in our Polymarket API guide.
Minimizing Fees: The Playbook
Default to limit orders. The maker/taker split is the whole game; market orders are for genuine urgency. Know your category. Before building any repeated strategy, check whether its markets carry taker fees. The same edge can be profitable in one category and a donation in another. Count all five costs, not one. A "free" trade that crosses a wide spread on a thin book paid plenty; fee-aware traders think in total cost per trade. And on thin edges, re-verify quarterly. The 2026 changes caught traders mid-strategy; schedules are living documents.
How Polymarket Fees Compare
Versus the other big venues: Kalshi runs the same shape of formula with a 0.07 coefficient on most series, so a contract at 50 cents peaks near 1.75 cents, rounded up to the next cent per order. That matches Polymarket's crypto rate and sits well above its 0.04 politics and finance rate, which is a genuine gap if you trade the same event on both books. Kalshi makers pay nothing on most markets and a reduced fee on designated ones, while Polymarket makers pay nothing anywhere and share the rebate pool. Robinhood's event contracts moved to a price-scaled commission on 1 June 2026 (10% × price × (1 - price) per contract, halved with a Gold subscription, rounded up, plus exchange fees). One more distinction worth knowing: the CFTC-regulated Polymarket US exchange publishes its own schedule, a lower 0.06 taker coefficient at the time of writing plus volume rebates for large traders, so don't assume the global numbers apply there or the other way round. The comparison matters most for cross-venue traders, where the same gap can clear one venue's fees and die on another's. That math is what we walk through in the arbitrage guide, with the platform-level trade-offs in Polymarket vs Kalshi.
Frequently Asked Questions
Does Polymarket charge fees?
Yes, since early 2026: taker fees on most market categories, while maker orders (resting limit orders) trade free and share a daily rebate pool. The fee scales with price and peaks at 50 cents, between 1 and 1.75 cents per share depending on the category, and geopolitics markets were still fee-free at the time of writing. The standard app flow is gasless; API traders pay Polygon gas. Rates vary by category, and the official fee schedule is the current source.
How do I trade on Polymarket without fees?
Use limit orders that rest on the book: makers trade free. Set your price slightly away from the market and let it come to you. The trade-off is you're not guaranteed a fill, which is why urgent trades still pay the taker fee willingly.
Are there deposit or withdrawal fees?
Polymarket itself charges nothing to deposit or withdraw. What you do pay is crypto reality: network gas on transfers on and off Polygon, and whatever your on-ramp charges to get funds there in the first place, since services like Coinbase or MoonPay set their own rates. Those costs often exceed anything Polymarket charges on the trade itself.
Is Polymarket cheaper than Kalshi?
For resting limit orders, usually yes: Polymarket makers pay nothing anywhere and earn rebates, while Kalshi makers pay nothing on most markets and a reduced fee on designated ones. For instant market orders it depends on the category. Polymarket's politics and finance markets carry a lower coefficient than Kalshi's standard 0.07, while its crypto markets match it. Thin-edge traders should run both numbers for their specific trade.
Why did my profitable-looking trade lose money?
Usually the invisible costs: crossing a wide spread, moving a thin book with your own size, or a taker fee on a small edge. Count total cost per trade (spread plus impact plus fees) and "profitable-looking" gets honest fast.
Conclusion
Polymarket's fees reward exactly the behavior good trading requires anyway: patience (limit orders), size discipline (respect the book), and awareness (know your category, watch the schedule). Internalize the maker/taker split and count all five costs, and fees become a solved problem instead of a slow leak. For where fees bite hardest, cross-venue trades on thin margins, the arbitrage guide shows the full math with fees included.
One caveat before you act on any of this: it describes how a fee schedule works, and it is not financial, tax or legal advice. Which venue you can actually use, and how any of it is taxed, depends on where you live and on whether you are dealing with the global platform or the separate CFTC-regulated Polymarket US exchange.
