Polymarket Fees Explained: What You Actually Pay Per Trade (2026)
For most of its history, Polymarket's pitch was simple: zero trading fees. That is no longer true. Through 2026 Polymarket rolled out category-based taker fees across most of the platform — so if you are working off an old guide that says "Polymarket is free," you are going to be surprised at checkout.
This guide breaks down every real cost on Polymarket in 2026: the new trading fees, the markets that are still free, and the costs (spread, gas, deposits) that most guides ignore.
The short answer: Polymarket's 2026 cost structure
| Cost type | Amount | Who gets it |
|---|---|---|
| Taker fee (buys) | ~0.75%–1.8% near 50/50, by category | Polymarket (funds maker rebates) |
| Maker fee (resting limit orders) | Effectively 0% | — |
| Sell orders | No taker fee | — |
| World Events / Geopolitical markets | 0% (fee-free) | — |
| pUSD deposit / withdrawal | 0% (from Polymarket) | — |
| Polygon gas | ~$0.001–0.01 per trade | Polygon validators |
| Bid-ask spread | 1–10% by market | Liquidity providers |
| Fiat on-ramp (card, etc.) | 0–4.5% | Exchange/bridge |
The headline change: buying (taking) now costs a fee in most categories. Selling, resting limit orders, and world-events markets do not.
Trading fees: no longer zero
This is the big 2026 update. Polymarket now charges a taker fee — the fee you pay when your order executes immediately against the existing book (a market buy). It started on crypto markets in early March 2026, expanded to Sports on March 30, 2026, and rolled out across Finance, Politics, Economics, Culture, Weather, and Tech from the same period.
A few things make this less painful than it sounds:- Only takers pay. If you place a resting limit order and wait for it to fill, you are a maker and generally pay 0%.
- Sell orders are not charged a taker fee. The fee hits when you buy in, not when you exit.
- The fee scales with price. It peaks around the 50/50 point and shrinks as a share approaches 1¢ or 99¢. Cheap long-shot and near-certain shares are barely touched.
- World Events and Geopolitical markets stay completely fee-free.
Taker fee by category (approximate, near the 50¢ price point)
| Category | Peak taker fee |
|---|---|
| Sports | ~0.75% |
| Politics / Finance / Tech | ~1.0% |
| Economics / Culture / Weather | ~1.25% |
| Crypto | ~1.8% |
| World Events / Geopolitical | 0% (free) |
Polymarket computes the exact fee with a formula that bends the rate down toward the price extremes, so these are the peak rates at maximum uncertainty — most real trades pay less. As a rule of thumb: a 100-share sports trade at 50¢ costs roughly $0.38 in fees.
The maker rebate
The taker fees you pay do not just vanish into Polymarket's pocket. A large share of collected fees — reported at around 25% (20% on crypto) — is paid back daily to makers: the traders providing liquidity with resting limit orders. So if you trade patiently with limit orders, you can pay near-zero fees and even earn a rebate.
How Polymarket still compares to the competition
Even with fees, Polymarket remains cheap relative to the alternatives — and you can sidestep most of the cost by trading as a maker:
| Platform | Cost to trade | On a $1,000 buy |
|---|---|---|
| Polymarket (taker, sports) | ~0.75% | ~$7.50 |
| Polymarket (maker / limit order) | ~0% | ~$0 |
| Polymarket (world events) | 0% | $0 |
| Kalshi | ~1–2% | $10–$20 |
| PredictIt | 10% on profits | up to $100 |
| Sportsbooks | 5–10% baked into odds | $50–$100 implicit |
The takeaway: Polymarket is no longer free, but for a patient trader using limit orders — or anyone trading world-events markets — it can still be close to it.
The spread: often your biggest real cost
The bid-ask spread is still the cost most traders underestimate, and on thin markets it dwarfs the new taker fee.
When a market shows 62%, that is the midpoint. The actual buy price might be 64¢ and the sell 60¢. That 4¢ gap is what you pay to get in and out.
What drives spread size:- Liquidity: high-volume markets (major elections, Fed decisions) run 1–2% spreads; niche markets can be 5–15%.
- Time to resolution: markets resolving soon tend to tighten as the price converges.
- Uncertainty: when opinion is genuinely split, liquidity concentrates near the midpoint.
- Trade the highest-volume markets in each category.
- Use limit orders instead of market orders — this also makes you a maker and dodges the taker fee.
- Skip markets where the spread is bigger than your estimated edge.
Deposit costs
Polymarket charges nothing to deposit, and there are no fees to deposit or withdraw pUSD (its 2026 collateral token). But the funding method you choose can cost you.
| Method | Cost | Notes |
|---|---|---|
| USDC via Polygon (from an exchange) | Free–$0.10 | Cheapest route |
| Cross-chain bridge | $2–5 or ~0.3% | Network-dependent |
| Card / fiat on-ramp (MoonPay, Transak) | 3.5–4.5% + flat fee | Convenient but pricey |
Polygon gas fees
Every Polymarket transaction settles on Polygon, which needs a tiny gas fee paid in POL.
- Typical trade: $0.001–$0.01
- During congestion: $0.05–$0.20
- For comparison, the same action on Ethereum would cost $5–$50.
Polymarket often seeds new wallets with a little POL so your first trades just work. For nearly everyone, gas is a rounding error.
Withdrawal costs
Polymarket charges zero to withdraw, and pUSD withdrawals are fee-free. The only costs are Polygon gas (cents), plus any fee from an exchange if you later convert back to fiat. For the full process, see our how to withdraw from Polymarket guide.
Polymarket US: the regulated exchange
Polymarket's US platform — built on the CFTC-licensed QCEX it acquired — runs its own fee schedule, updated in 2026 with a per-contract taker fee, a maker rebate, and a per-100-contract cap. It is structured differently from the global platform but lands in the same low-cost ballpark and remains far cheaper than a sportsbook's built-in margin. Check the current US fee schedule before trading if you are on the regulated version.
Hidden costs that actually matter
Opportunity cost of locked capital. A long-duration market ties up money that can't work elsewhere. $5,000 locked in a six-month market is real money not earning yield — size long-dated positions with that in mind. Fee-on-entry math. Because the taker fee now hits your buy, your true break-even is slightly worse than the raw odds suggest. On thin-edge trades, factor the fee in before you click — or use a limit order and avoid it entirely.Bottom line
Polymarket in 2026 is no longer the zero-fee platform it once was, but the cost is manageable and largely avoidable:
- Buy with market orders → you pay a taker fee (~0.75% sports up to ~1.8% crypto, peaking near 50/50).
- Use limit orders → you become a maker, pay ~0%, and may earn a rebate.
- Trade World Events markets → still completely free.
- Selling is never charged a taker fee.
- The spread is still usually your biggest cost — trade liquid markets and use limit orders.
