Key takeaway: Polymarket charges multiple fees across different activities—trading fees (2% maker/3% taker), order cancellation fees, and withdrawal costs that vary by blockchain. Understanding these layered costs is essential before you start trading, as they can significantly impact your profit margins on prediction markets.
Understanding Polymarket's Multi-Layer Fee Structure
Polymarket operates as a decentralised prediction market platform, and like any financial marketplace, it generates revenue through fees charged to users. However, the fee structure isn't always immediately transparent, and many traders discover hidden costs only after they've begun trading. This article breaks down exactly what you'll pay when using Polymarket in 2026, helping you make informed decisions about whether the platform's cost model suits your trading strategy.
The platform charges fees at multiple touchpoints: when you place trades, when you cancel orders, and when you withdraw funds. Each of these has different rates depending on your activity type and the blockchain network you're using. Understanding these costs upfront is crucial because they directly affect your profitability. A trade that looks profitable on paper might actually result in a loss once all fees are factored in.
Trading Fees: Maker vs. Taker Costs
The primary cost you'll encounter on Polymarket is the trading fee, which operates on a maker-taker model similar to traditional exchanges. This model incentivises liquidity provision by charging different rates depending on whether you're adding liquidity to the market (maker) or removing it (taker).
Maker fees: When you place a limit order that doesn't immediately match with an existing order, you're acting as a maker—you're creating liquidity. Polymarket charges 2% on maker orders. This means if you place a limit order to buy 100 shares of a market at a certain price, and that order sits on the order book until someone else matches it, you'll pay 2% of the transaction value as a fee.
Taker fees: When you place a market order or a limit order that immediately matches with existing orders, you're acting as a taker—you're removing liquidity. Polymarket charges 3% on taker orders. If you want to buy 100 shares immediately at the current market price, you'll pay 3% of the transaction value.
The difference between 2% and 3% might seem modest, but it compounds quickly. On a £1,000 trade, you're looking at £20 for a maker order or £30 for a taker order. Over multiple trades, these costs add up significantly. A trader making ten £1,000 taker orders would pay £300 in fees alone, which is a substantial drag on returns.
Order Cancellation Fees and Hidden Costs
Beyond the standard trading fees, Polymarket charges fees for cancelling orders—a cost that many new users don't anticipate. If you place an order and then decide to cancel it before it's filled, you'll incur a cancellation fee. These fees exist to discourage market manipulation and spam, but they represent a real cost to traders who change their minds or adjust their positions.
The cancellation fee structure varies depending on the blockchain network and current gas prices. On Ethereum, for example, cancellation fees can range from a few pounds to significantly more during periods of network congestion. This creates an asymmetric cost structure where volatile market conditions—precisely when you might want to cancel orders—also make cancellation more expensive.
Additionally, there are indirect costs associated with blockchain interactions. Every transaction on Polymarket requires blockchain confirmation, and you'll pay network gas fees on top of Polymarket's platform fees. These gas fees are entirely separate from Polymarket's fees and go to the blockchain network itself. During busy periods, gas fees can spike dramatically, making even small trades uneconomical.
Important risk disclosure: Prediction markets carry substantial financial risk. You can lose your entire investment. The fees described here reduce your potential returns whilst your losses remain unaffected. Always trade with money you can afford to lose, and never assume fees are your only cost—market risk is far more significant.
Deposit and Withdrawal Costs: The Often-Overlooked Expense
Getting money into and out of Polymarket involves additional costs that vary significantly based on your chosen method and blockchain network. These costs are often overlooked by new users but can represent a substantial portion of your total trading costs, especially if you're making smaller trades or frequent deposits and withdrawals.
Deposit costs: Polymarket accepts deposits via several blockchain networks, including Ethereum, Polygon, and others. When you deposit funds, you're paying blockchain network fees to transfer your assets to Polymarket's smart contracts. These fees vary dramatically based on network congestion. Depositing via Polygon is typically much cheaper than Ethereum, sometimes costing just a few pence rather than several pounds, but Polygon has lower liquidity on some markets.
Withdrawal costs: Withdrawing funds from Polymarket incurs similar blockchain fees. You'll pay to transfer your funds from Polymarket's smart contracts back to your personal wallet. Again, the network you choose significantly impacts these costs. A withdrawal via Ethereum might cost £5–£20 depending on network conditions, whilst a Polygon withdrawal might cost just 50p–£2.
These withdrawal and deposit costs create a friction cost that affects your overall profitability. If you deposit £500, trade it, and withdraw your profits, you might pay £10–£30 in network fees alone, before considering Polymarket's trading fees. This means you need to generate meaningful returns just to break even on transaction costs.
Fee Comparison: How Polymarket Stacks Against Competitors
To contextualise Polymarket's fees, it's worth comparing them to other prediction market platforms and traditional exchanges. Polymarket's 2–3% trading fees are actually quite competitive within the prediction market space, where some platforms charge 4–5% or higher. However, this comparison is complicated by the fact that different platforms operate on different blockchain networks with different fee structures.
Traditional financial exchanges typically charge much lower percentage fees—often 0.1% or less for retail traders—but they don't involve blockchain transaction costs. Prediction markets, by their nature, involve blockchain interactions, which adds a cost layer that traditional exchanges don't have. This is a fundamental difference in how these platforms operate, not necessarily a sign that Polymarket is overcharging.
Some alternative prediction market platforms use layer-2 blockchain solutions or different blockchain networks entirely, which can result in lower overall costs. However, these platforms may have lower liquidity or fewer markets available. Polymarket's fee structure reflects its position as one of the larger, more liquid prediction market platforms in 2026.
Strategies to Minimise Your Polymarket Fees
Whilst you can't eliminate Polymarket's fees, you can employ several strategies to minimise their impact on your trading:
- Favour maker orders over taker orders: Placing limit orders that add liquidity costs 2% instead of 3%. If you're patient and don't need immediate execution, using maker orders can save you 1% per trade. Over dozens of trades, this adds up significantly.
- Use cheaper blockchain networks: Deposit and withdraw via Polygon or other low-cost networks rather than Ethereum. The difference in network fees can be substantial, especially for smaller transactions.
- Batch your transactions: Instead of making multiple small deposits and withdrawals, consolidate them into fewer, larger transactions. This reduces the number of times you pay network fees.
- Trade larger positions: Fees are charged as a percentage, so larger positions distribute the fixed costs of network interaction across more capital. Very small trades become uneconomical once fees are factored in.
- Avoid frequent order cancellations: Each cancellation costs money. Plan your orders carefully before placing them to avoid the expense of cancellations.
- Monitor network conditions: Blockchain network fees fluctuate based on congestion. Depositing and withdrawing during off-peak hours (typically early morning UTC) can result in significantly lower network fees.
Fee Transparency and the "Polymarket Scam?" Question
One question that frequently appears in online discussions is whether Polymarket's fees constitute a scam. To be clear: Polymarket's fees, whilst not always immediately obvious, are not a scam in the legal sense. The platform discloses its fee structure in its terms of service and on its website. However, the layered nature of fees—combining Polymarket's fees with blockchain network fees—can make the total cost of trading less transparent than users might prefer.
The confusion often arises because users don't realise they're paying multiple types of fees simultaneously. A trader might see a 3% taker fee and not immediately understand that they're also paying blockchain gas fees, and that these costs are in addition to their trading fees. This lack of upfront clarity about total costs is a legitimate criticism of the platform's user experience, though it's not unique to Polymarket—most decentralised finance platforms have similar cost structures.
What distinguishes a scam from simply high or opaque fees is intent to deceive. Polymarket's fees are disclosed; they're just not always obvious to new users. The platform could certainly improve its user education around total costs, but the fees themselves are legitimate business expenses for operating a decentralised prediction market.
Frequently Asked Questions About Polymarket Fees

A: Polymarket can adjust its fee structure, though significant changes would likely be announced in advance. Always check the platform's current fee schedule before trading.
Q: Are there any accounts or membership levels that offer lower fees?
A: As of 2026, Polymarket does not offer tiered fee structures based on trading volume or membership levels. All users pay the same percentage fees.
Making an Informed Decision About Polymarket's Costs
Polymarket's fee structure is neither unusually high nor particularly transparent, but it's a legitimate cost of using a decentralised prediction market platform. The 2–3% trading fees, combined with blockchain network costs, mean you need to generate meaningful returns to profit. Before you start trading, calculate your break-even point based on your expected trade size and frequency. A trader making small, frequent trades will find fees consume a larger percentage of their capital than a trader making larger, less frequent trades.
The platform's costs are real and material, and they should factor into your decision about whether to use Polymarket. However, these costs alone don't make Polymarket a scam—they're simply part of how decentralised prediction markets operate in 2026. What matters is understanding these costs upfront and trading accordingly.
