Quick facts about event trading costs
- Event contracts are priced between $0.01 and $0.99.
- Market demand sets the event trading cost, not the prediction market sites.
- Each contract has a built-in fee that’s usually $0.01.
What are event trading costs?
First off, I’ll explain what event trading is. It simply involves buying and selling contracts, which are financial derivatives. In plain English, the contracts let you take a position on how a real world event will turn out.
I’ve reviewed several prediction market sites, and they always display the event contracts as Yes or No. You pick Yes if you’re backing the event to happen, and No if you’re calling it dead in the water. Other traders do the same, and the demand sets the event contract price.
How to read event contract prices
Now, the costs of event trading are usually between $0.01 and $0.99, totaling $1. Let’s say you spot a Yes contract going for $0.60. That’s the market telling you that there’s roughly a 60% shot that the outcome will happen. Sometimes, spreads and last trade wiggle a bit, and Yes and No prices may not add to $1.00.
Here’s an example for an NBA matchup that popped up during my review:
| Team | Yes/No event contract price |
| Mavericks | $0.78/$0.23 |
| Raptors | $0.23/$0.78 |
From the above, the market thinks the Mavericks have a 78% chance of winning, while it’s just 23% for the Raptors. If sentiments switch up and more traders start backing the Raptors, their contract price moves up, while that of the Mavericks drops.
After you grab a contract, you’re not stuck twiddling your thumbs until the event wraps up. It’s a trade, so prices move up and down with supply and demand. If the price jumps, you can sell early and lock in some potential payouts. Meanwhile, if it looks like the cost is tanking, you can cut your losses and sell before it sinks further.
Is event trading legal in the US?
I’d say yes. Event contracts and prediction markets are legal in many states because they’re simply trading. The sites offering them are not just online sportsbooks that hand out fixed probabilities for possible outcomes.
That said, check your local rules and stick to licensed trading sites to stay safe. A legit prediction market brand in the US will be regulated by the Commodity Futures Trading Commission (CFTC). The prediction market type also plays a role in whether you can trade or not.

Cost of event trading fees
Event trading in prediction markets won’t break the bank. I say so because most sites I’ve used don't charge for funding your account. They only tack on a small fee per contract, usually $0.01 or $0.02. The highest I’ve seen is $0.05.
Let’s go back to the example I gave earlier, where the Yes/No event contracts for the Mavericks are $0.78 and $0.23. Add them up, and you get $1.01. That extra $0.01 on top of the $1 is the event trading fee. In my experience, the fee will exceed $0.01 if the prediction market site draws its event contracts from a third party.
How event trading is settled
At this point, I’m sure you’re up to speed with how to read market prices and the fees that come alongside. But what happens when the contract settles? Well, that aspect is still simple.
Every winning event contract settles $1 flat since the prices always sit between $0.01 and $0.99. That means if you snag a contract for $0.75 and it hits, you pocket a $0.25 profit. You can buy multiple contracts for the same event, not just one.
For example, I grabbed 100 contracts on an NFL game at $0.60 each, spending $60 in total. Things played out well, and I scored $100, with a tidy $40 gain.

Conclusion – Trade event contracts safely
Event contract trading is easy to grasp, as you’re just picking Yes or No on various outcomes. As you buy or sell, the market does its thing by setting the cost based on demand and supply. Prediction market sites don’t touch the price; they pair your orders with those of other players.
Trading event contracts is above board in most parts of the US. Make sure you join a site that’s CFTC-regulated, so you don’t have to worry about shady business. To save you the legwork, I’ve already rounded up the top options.
