Polymarket Fees Explained: Every Cost You'll Pay in 2026 (And How to Minimize Them)

As of March 2026, Polymarket charges taker fees on nearly every market category: Crypto 1.80%, Economics 1.50%, Mentions 1.56%, Culture 1.25%, Weather 1.25%, Finance 1.00%, Politics 1.00%, Tech 1.00%, and Sports 0.75%. Only geopolitics markets remain free. US traders on the regulated exchange pay a flat 0.30% taker fee with a 0.20% maker rebate. Limit orders (maker orders) are free on both platforms.

If you're still operating under the assumption that Polymarket is free to trade, you're leaving money on the table — or more accurately, Polymarket is taking it from yours. This guide breaks down every fee you'll encounter in 2026: what you pay, when you pay it, and how to structure your trades to keep costs as low as possible.

Polymarket's Fee Model: US vs Global

Polymarket now operates two distinct platforms with different fee structures. Which one applies to you depends on where you live.

Polymarket US Exchange

The US exchange, launched after Polymarket acquired CFTC-licensed QCEX in late 2025, uses a straightforward flat-rate model:

Order Type	Fee
Taker (market order)	0.30% of contract premium
Maker (limit order)	-0.20% rebate (you get paid)

That maker rebate is real money back. Place a limit order for 1,000 contracts at $0.65 and when it fills, you receive a $1.30 rebate instead of paying a fee. The minimum fee or rebate is $0.001 per trade, rounded to the nearest $0.001.

Example: Buy 500 YES shares at $0.60 with a market order. Your cost: 500 x $0.60 = $300 in contracts, plus $0.90 in taker fees. That's 0.30% — barely noticeable on a single trade, but it adds up across hundreds of trades per month.

Polymarket Global (International)

The international platform uses a dynamic taker fee model where your fee depends on two things: the market category and the current share price.

Makers always pay zero fees. If you place a limit order and wait for it to be filled, you pay nothing regardless of category.

Taker fees follow a curve that peaks when the share price is at $0.50 (maximum uncertainty) and approaches zero as the price nears $0.00 or $1.00. The logic: trades at extreme probabilities are less risky for the platform, so they cost less.

Here are the peak taker fee rates by category (what you'd pay at exactly 50/50 odds):

Market Category	Peak Taker Fee (at $0.50)
Crypto	1.80%
Mentions	1.56%
Economics	1.50%
Culture	1.25%
Weather	1.25%
Other / General	1.25%
Finance	1.00%
Politics	1.00%
Tech	1.00%
Sports	0.75%
Geopolitics & World Events	0% (free)

If you're trading a political market priced at $0.80, your effective taker fee is significantly lower than the 1.00% peak — the curve tapers off as the price moves away from $0.50.

Geopolitics markets remain completely free to trade for both makers and takers. If you're looking for zero-cost trading, that's where to find it.

The Dynamic Fee Formula (For the Math-Inclined)

Polymarket's international taker fee isn't arbitrary. It follows a published formula:

Fee = C x feeRate x p x (1 - p)^exponent

Where:

• C = number of shares traded
• p = share price (probability)
• feeRate = category-specific rate multiplier
• exponent = curve steepness parameter

The p x (1 - p) component is what creates the bell curve shape. At p = 0.50, the product is 0.25 (maximum fee). At p = 0.90, it drops to 0.09. At p = 0.95, just 0.0475. This means buying shares in high-confidence markets costs a fraction of what you'd pay in a coin-flip market.

Practical implication: If you're buying YES at $0.85 on a political market, your effective fee is roughly 0.26% — not the 1.00% headline rate. The peak rates in the table above only hit at exactly $0.50.

Fees are rounded to 4 decimal places with a minimum charge of 0.0001 USDC per trade.

Deposit Fees

Polymarket charges zero deposit fees. But the path you take to get money onto the platform determines how much you actually pay.

Deposit Method	Fee	Speed
USDC from crypto wallet (Polygon)	~$0.01 gas	Seconds
USDC from exchange (Coinbase, Kraken)	Exchange withdrawal fee (varies)	Minutes
Debit card via MoonPay	2-3% processing fee	Minutes
Bank transfer to exchange, then USDC	Usually free ACH	1-3 days

The cheapest path: buy USDC on an exchange like Coinbase (low or zero fee for the purchase), withdraw it to your Polymarket wallet on Polygon (small network fee), and you're in for under a dollar in total costs. The most expensive path: debit card through MoonPay at 2-3%. On a $1,000 deposit, that's $20-30 gone before you've placed a single trade.

If you're depositing more than a few hundred dollars, the extra step of routing through a crypto exchange saves real money.

Withdrawal Fees

Polymarket charges zero withdrawal fees. The costs you encounter are from the networks and services you use to move funds off-platform:

Withdrawal Path	Fee
USDC to Polygon wallet	Under $0.01 (Polygon gas)
Bridge USDC to Ethereum	$1-20+ (Ethereum gas, varies by congestion)
Off-ramp USDC to USD via exchange	Exchange-specific (Coinbase: free for bank transfer)
MoonPay debit card withdrawal	Processing fee applies

The cheapest exit: withdraw USDC to your exchange wallet on Polygon, convert to USD, and bank transfer out. Total cost: essentially zero beyond the negligible Polygon gas. Bridging to Ethereum is only necessary if your destination doesn't support Polygon — and Ethereum gas fees fluctuate wildly, so time it during off-peak hours if you can.

Hidden Costs Most Traders Miss

The fees above are the obvious ones. These are the costs that quietly eat your edge:

1. USDC Conversion Costs

If you're starting from USD, you need to convert to USDC somewhere. Most exchanges charge 0-1.5% for this conversion. On-ramp services like MoonPay charge 2-3%. Over the course of a year of active trading with regular deposits, these conversion fees can exceed your actual trading fees.

2. Bid-Ask Spread

The spread — the gap between the highest buy order and the lowest sell order — is a cost you pay on every trade even though it's not labeled as a "fee." On popular markets with deep liquidity, spreads are tight (often 1-2 cents). On niche markets with fewer participants, spreads can blow out to 5-10 cents, effectively adding 5-10% to your round-trip trading cost.

Average Polymarket spreads tightened from roughly 4.5% in 2023 to about 1.2% by late 2025. Still, always check the order book depth before placing large orders.

3. Slippage on Large Orders

If you're buying 10,000 shares on a market with $5,000 of depth at the best price, you won't get the quoted price on all of them. The rest fill at progressively worse prices. For small traders ($50-500 per trade), this is irrelevant. For larger positions, it's a meaningful cost.

4. Opportunity Cost

Funds sitting in USDC on Polygon aren't earning yield elsewhere. If you're holding $10,000 in your Polymarket wallet waiting for the right trade, that capital could be earning 4-5% APY in a savings account or money market fund. Not a "fee" per se, but a real cost of participating.

How to Minimize Your Polymarket Fees

Here's the playbook for keeping costs as low as possible:

1. Use limit orders for everything. Maker orders are free on both US and Global platforms. On the US exchange, you actually get a 0.20% rebate. The only tradeoff is speed — your order might not fill immediately. For most prediction market trades, that patience pays for itself many times over.

2. Deposit USDC directly from a crypto exchange. Skip the debit card on-ramp entirely. Buy USDC on Coinbase or a similar exchange and withdraw to Polygon. You'll save 2-3% on every deposit.

3. Trade liquid markets. Tighter spreads mean lower effective costs. Compare market liquidity across platforms before committing to a trade.

4. Batch your deposits. If you're going to trade $2,000 this month, deposit it once rather than four $500 deposits. Each deposit through a card processor has a minimum fee floor, so batching reduces your per-dollar cost.

5. Check the fee category before trading. On the global platform, geopolitics markets have zero fees. Sports markets charge the least among fee-bearing categories (0.75% peak). Crypto markets are the most expensive (1.80% peak). The same conviction applied to different categories has different cost profiles.

6. Use the fee calculator. Before any trade, plug your numbers into Prediction Hunt's fee calculator to see your exact net payout after all platform fees.

Polymarket Fees vs the Competition

How does Polymarket stack up against every other prediction market platform in 2026?

Platform	Taker Fee	Maker Fee	Withdrawal Fee	Best For
Polymarket US	0.30% flat	-0.20% rebate	Free	Lowest-cost US trading
Polymarket Global	0-1.80% (dynamic)	Free	Free	International, high volume
Kalshi	0.07-1.75% (formula)	Reduced rate	Free (ACH)	US-regulated, sports/politics
PredictIt	10% of profits	10% of profits	5% of withdrawal	Avoid if possible
Robinhood	~$0.02/contract	~$0.02/contract	Free	Casual US traders

At even odds (50/50 market), on a $100 position:

• Polymarket US: $0.30 fee
• Polymarket Global (politics): ~$0.25 fee
• Kalshi: ~$1.75 fee
• PredictIt: $0 upfront, but 10% of any profit + 5% withdrawal

Polymarket is the cheapest platform for most trade sizes and categories. The only scenario where Kalshi approaches parity is on extreme-probability contracts (above $0.95 or below $0.05) where both platforms charge near-zero.
