Event Trading Costs and Expenses for 2026: A Detailed Breakdown of Potential Expenses

Prediction market trading is completely different to online sports betting, and where at online sportsbooks you have odds set by the operator, with event trading, you are engaging in peer-to-peer trading for prediction propositions.

Because of this peer-to-peer functionality, you need to understand the cost of event trading. Operators who facilitate the peer-to-peer trading typically have a set fee structure which can impact your overall balance and what you get back. We take a look at the cost of event trading below, and common fees you may encounter.

Event Trading is NOT online betting

Before we look at the costs of event trading, it’s important to understand why there are even fees in the first place. With online sportsbooks, you have odds for different wagers - you purchase those odds directly from the sportsbook and if you get it wrong, they keep your stake. There’s nothing like that with prediction markets. Instead, you are engaging in peer to peer trading for trade contracts relating to different real-world propositions.

The operators therefore charge fees for facilitating your trading - they have to do this to cover their costs and be able to offer the service. For more info on the types of predictions and other useful features, feel free to check out our guide on what is event trading for a longer explanation. But in short, trading fees are essential because of how the sites work.

Common costs of event trading you will encounter at prediction market sites

Now that we know the difference, and why trade contracts have associated fees, we can look at the three main types of fee you may encounter:

• Trade contract purchase fee.
• Trade contract selling fee.
• Trade contract payout fee.

The first thing you can do at prediction market sites is purchase yes or no trade contracts for a range of events. Typically, there will be an associated fee for trade contract purchases. This could be a set fee per $1 trade contract, or it could be a percentage based on your overall transaction.

Similarly, if the market price changes in your favor, you can also sell your trade contracts. There is usually a selling fee too, which again, may have a set fee, such as $0.02 per contract, or a percentage, such as 0.50% of your overall selling value.

Lastly, you can also hold your trade contracts and wait to see if you got the prediction right. If you got it right, you will get a $1 payout for each contract. However, there is usually a profit fee which we have found is usually percentage-based.

Pros and cons of event trading fees

You HAVE to look at the fee structure of a prediction market site before you sign up as it directly impacts your money and what you can potentially get out of a trade. Usually though, we’ve found that the fee structures are incredibly simple, and that the operator will show what money you actually get after any fees are deducted.

Pros & Cons

• Simple free structures
• Final values are often shown
• The fee is usually comparatively small

• It ultimately affects your potential bottom line

An example of the costs of event trading

Below we have created a theoretical example of some trading fees and how this impacts your overall cash flow:

Let’s say that you wanted to purchase trade contracts for the proposition, Will Bitcoin cross $100k again this year? After research, you think it won’t, so you purchase 10,000 trade contracts for “no” at $0.78 each. With the above fee structure, that would actually translate to:

• 10,000 “no” trade contracts at $0.78 each = $7,800.
• Purchase fee for 10,000 contracts = $0.02 x 10,000 = $200.00
• Total purchase price = $8,000.

The year rolls on, and you decide to hold as you think the crypto market isn’t picking up pace. 2025 passes, and Bitcoin doesn’t reach $100k again. This means you get a $1 payout for each contract, but with the costs of event trading, that translates to:

• 10,000 “no” trade contracts with a payout of $1 each = $10,000.
• Profit fee for the payout = $10,000*0.015 = $150.00
• Final payout = $9,850.

This means that you increased your balance by $1,850 after fees. You can now see the impact that the costs of event trading have, and how it affects your bottom line. For insight into potential fees, you can check out our Kalshi vs. Robinhood guide as these are two reputable operators in the US.
