Polymarket Fees Explained: 2026 Taker Rates and Rebates
Polymarket fees changed in 2026: after years of zero trading fees, the venue introduced category-based taker fees, and understanding them now directly affects whether a trade is worth placing. Only takers pay — makers are never charged — and the fee is symmetric around the 50% price point, meaning a trade at 30 cents or 70 cents costs the same dollar amount. The exact ceiling depends on which category the market falls into, and it ranges from $0.75 to $1.80 per 100 shares. Here's the full breakdown, with a worked example.
How the Fee Is Calculated
The taker fee is charged in USDC and scales with how close the trade price sits to 50 cents. It peaks at the 50% probability mark and tapers down toward the 1 cent and 99 cent extremes, where fees shrink to near nothing. This shape means a near-certain outcome — a contract trading at 95 cents, for example — costs very little in fees to trade, while a genuine coin-flip market at 50 cents carries the maximum fee for its category. Only the taker side pays; if you're the one crossing the spread to get filled immediately, the fee applies. If you're resting a limit order that someone else fills, you pay nothing and may earn a rebate instead.
2026 Category Fee Table
| Category | Max Taker Fee per 100 Shares |
|---|---|
| Sports | $0.75 |
| Politics / Finance / Tech | $1.00 |
| Economics / Culture / Weather / Other | $1.25 |
| Crypto | $1.80 |
| Geopolitical / world events | Fee-free |
These figures are the maximum, charged at the 50-cent price point for that category, per Polymarket's official fee documentation. This schedule is new for 2026 and Polymarket has already signaled it may adjust rates — treat these as current, not permanent, and check the official page before sizing a position around the fee math.
Worked Example: Buying 100 Shares at 50 Cents
Say you're a taker buying 100 shares of a politics contract at $0.50 — the maximum-fee price point for that category. The politics/finance/tech ceiling is $1.00 per 100 shares, so at exactly 50 cents you'd pay the full $1.00 fee on top of your $50 cost basis, for $51.00 total. Move that same trade to a sports market instead and the ceiling drops to $0.75 per 100 shares — $50.75 total for the identical position size and price. Now compare a crypto-category contract at the same 50-cent price: the $1.80 ceiling makes it the most expensive category to take size in, at $51.80 total. If that same politics trade were instead priced at 90 cents — near the edge of the range — the fee tapers down well below the $1.00 ceiling, since the schedule shrinks as price moves away from 50%.
Geopolitical Markets Are Fee-Free
World-event and geopolitical markets carry no taker fee at all under the 2026 schedule. That's a meaningful exception if your trading concentrates in that category — a large position in a geopolitical contract costs you nothing beyond the spread itself and Polygon gas, which is typically under $0.01 per transaction and often subsidized through meta-transactions. Compare that to a same-sized crypto position, where the $1.80-per-100-share ceiling adds real cost that has to be justified by your edge.
Maker Rebates: Getting Paid to Provide Liquidity
Makers — traders who post resting limit orders that someone else fills — never pay the taker fee, and Polymarket goes a step further with its Maker Rebates Program: 25% of all taker fees collected in a category is paid back to makers daily (20% on crypto categories). This is separate from the broader Liquidity Rewards Program, which scores resting orders on closeness to the book's midpoint and two-sided depth, sampled roughly every minute, and pays out in pUSD daily at 00:00 UTC with a $1/day minimum payout threshold. Combined, these two programs are why serious market makers on Polymarket focus on staying resting near the midpoint rather than crossing the spread as a taker — the fee structure is built to reward exactly that behavior.
Gas and Withdrawal Costs on Top of Trading Fees
Trading fees aren't the only cost. Polymarket settles on Polygon, where gas is typically under $0.01 per transaction and frequently subsidized entirely through meta-transactions, so it rarely factors into per-trade economics. Withdrawing collateral off Polygon costs a similar sub-cent amount, but bridging funds onward to Ethereum mainnet can run $1 to $20+ depending on network congestion — a cost worth factoring in if you plan to move funds off Polymarket frequently rather than leaving USDC/pUSD parked in your trading wallet.
Fee-Free Doesn't Mean Cost-Free
It's worth separating "no trading fee" from "no cost." A fee-free geopolitical trade still crosses a bid-ask spread, and that spread is a real cost even though it never shows up as a line-item fee. Thin geopolitical markets can carry wider spreads than a high-volume politics contract that does charge the $1.00-per-100-share taker fee, so the fee-free label isn't automatically the cheaper trade once you account for execution price. Always check the actual fill price against the last quoted midpoint, not just whether a fee line appears.
How This Changes Trade Sizing
If you're a frequent taker in the crypto category, the $1.80-per-100-share ceiling means you need a real edge — not just a hunch — to clear the cost of entry and exit on both sides of a round trip. On a $0.50 crypto trade, buying and later selling 100 shares as a taker both times could cost close to $3.60 in fees alone before accounting for spread. Compare that to a fee-free geopolitical position, where the same round trip costs nothing beyond gas and spread. This is exactly the kind of math a cross-venue arbitrage scanner needs to run automatically — a spread that looks profitable before fees can disappear once the category-specific taker cost is applied on both legs.
PolyMarketMaker's arbitrage scanner builds Polymarket's category fee schedule directly into its spread calculations across Polymarket US, Polymarket global, Kalshi, and PredictIt, so a flagged spread already accounts for what each leg actually costs to execute.
