Polymarket is one of the premier prediction trading exchanges, and if you want to give it a try, you need to understand how Polymarket fees work as this can impact your potential returns.
Until recently, Polymarket operated under a largely fee-free structure, but this has just changed, and we’ve been digging into what these changes mean, and what traders will have to start potentially paying. If you read on, we give you a full breakdown on the current Polymarket fee structure below, including trading and payments.

How does Polymarket work?
To understand the Polymarket fees, we first need to look at how the site works. Polymarket facilitates the peer-2-peer trading of yes or no contracts on real world events such as sports, politics, culture, tech, the weather, and Polymarket election trading.
You buy and sell yes or no contracts with other users, and you can potentially hold them to try and settle the contracts and make a return. If you hold your trade contracts and wait for the prediction event to happen, if you got the prediction right, you'll get a $1 return minus any fees - THIS is why understanding the Polymarket fees is important as they directly impact the potential returns you can get either from selling your trade contracts, or settling them.
In the below table we have given some example of predictions that were live when we wrote this guide:
| Prediction | Yes Contract | No Contract | Category |
|---|---|---|---|
| Republican Presidential Nominee in 2028 (J.D. Vance) | 36.9c | 63.2c | Politics |
| Minnesota Timberwolves vs. Philadelphia 76ers (Minnesota to win) | 44c | 57c | Sports |
| Bitcoin 5 Minute Price Prediction (Up or Down) | 1c | 0c | Crypto |
| Eurovision Winner 2026 (Finland) | 36.8c | 63.6c | Culture |
| Largest company by the end of April 2026? (NVIDIA) | 97.2c | 2.9c | Tech |
These are just a few examples and Polymarket has plenty more spanning a wide range of interesting categories– most of which also have excellent trade volume.

Everything you need to know about Polymarket fees
Until recently, Polymarket operated with minimal trading fees across most markets, although some categories had already introduced limited fees earlier in 2026. In March 2026, the platform announced a broader fee structure rollout across multiple market categories.
Our initial impression is that the fees appear broadly comparable to those seen on similar prediction market platforms, although actual costs vary depending on the market and trade type.
💸 Polymarket Deposit and Withdrawal Fees
The first thing to note is that Polymarket does NOT charge any payment fees for depositing or withdrawing USDC. This is a huge advantage as it means you get to trade with 100% of your deposit, and keep 100% of your returns (minus fees). It is important to note though, that while Polymarket does not charge payment fees, you might still get network and transaction fees depending on which crypto wallet or exchange you use, so make sure you are aware of these.
🌍 Polymarket Geopolitical and World Events Trading Fees
For whatever reason, Polymarket has chosen to keep its geopolitical and world events trading categories fee-free. This means that these two sections will continue exactly as they did before, and you don’t have to factor in trading fees when working with these predictions. We believe Polymarket does this as a gesture of good faith and to show that they are not profiting from world events where people have real connections.
⚖️ Polymarket Fees for Other Prediction Markets
Whether you’re using the Polymarket app or desktop site, you WILL be charged trading fees for all other markets including Polymarket sports predictions, crypto, finance, politics, economics, culture, weather, and tech. The fees are variable and dependant on the share price (i.e. the trade contract price). The simple rule to remember is that the closer the share price is to a representative 50% probability, the higher the fee will be. So, the maximum effective trading fee you can be charged is 1.80% which applies to a trade contract price of $0.50. Similarly, the lowest potential fee is 0.0001 USDC which we assume will be for 1c or 99c trade contracts. So, the closer your trade contract price is to $0.01 or $0.99, the LESS you pay, whereas the closer your trade contract is to $0.50, the MORE you pay. There is also the change that you can incur no fees as the decimal values can be rounded to 0.

We think the Polymarket fees they have implemented are fair, and we like that they work on a sliding scale based on the share price of your trade contracts. This gives you some flexibility, and it’s also important to remember that trade contracts for geopolitical and world events predictions still have no fees.
