NBA prediction markets allow you to trade event contracts for the outcomes of NBA games, Conference winners, Championship winners, and more. Whether or not you predict the outcomes directly determines whether you win or lose money.
The event contracts cost between $0.01 and $0.99 when you buy them. The price is tied to the real-time market probability of the outcomes. In other words, $0.50 = 50% chance. Once the event has passed, contracts tied to correct outcomes close at $1.00, with their opposite numbers closing at $0.00. For example.
Like all prediction markets, NBA event contracting involves buying and selling contracts that are tied to possible outcomes of events. These can include everything from regular-season NBA games to Championship winners, MVPs, and which teams will make the playoffs.
If you buy contracts tied to a prediction that winds up being correct, you will win money; if not, you’ll lose money. Many event contracts are binary, meaning that there are Yes/No answers, or in the case of NBA games, Away Team/Home Team.
As with soccer prediction markets, you can trade contracts that are tied to predictions for several types of NBA-related events. Here’s a rundown of the most popular prediction markets:
From the fun of trading to the high risks involved, here are the pros and cons of trading on your NBA predictions:
The prices of NBA event contracts always cost between $0.01 and $0.99 while the prediction market is still open. Once the market is resolved, the contracts that are tethered to the correct prediction close at $1.00. On the contrary, those tied to the incorrect predictions close at $0.00.
This gives you a profit if you made a correct prediction and a loss if you didn’t. For example, if you bought event contracts for $0.50 each and your prediction was correct, you’d make a $0.50 profit on each contract, minus any trading fees. If your predictions had been incorrect, you’d have lost the $0.50 you’d spent on each contract plus the trading fees you’d paid.
Here’s a summary of the key points:
As with all forms of trading, you can sell your event contracts as well as buy them. Reasons that you might want to sell your event contracts before the NBA game or market is resolved are numerous, but there are two main options:
Of course, to sell, you need to find buyers who aren’t always available. As with purchasing event contracts, the prices and market might change by the time your trade executes, if it does at all.
There are three ways that you can buy event contracts for the NBA and other prediction markets:
To give you a visual example of how these prediction markets work, here’s the prediction market for the Golden State Warriors at the Washington Wizards. We’ve taken this example in real time from Kalshi, which is one of the best NBA prediction sites according to our experts.
| 🏀 Teams | 📈 Chance | ✅ Yes | ❌ No |
| Golden State Warriors: | 66% | $0.67 | $0.34 |
| Washington Wizards: | 34% | $0.34 | $0.67 |
Now that we’ve explained how these prediction markets work, it’s time for our expert recommendations. Based on the market selection, trading volume, and other factors, these are the three sports prediction market sites that we believe are best for trading NBA event contracts:
| 🏀 Basketball prediction market platform | 🔞 Age limit | 🧑⚖ Regulation | 🏆 Best for |
|---|---|---|---|
| Kalshi | 18+ | CFTC | NBA trading volume |
| Polymarket | 18+ | CFTC | NBA Offseason markets |
| Crypto.com | 18+ | CFTC | Beginner-friendly interface |
Kalshi is the best overall prediction market platform for the NBA. You can access it via the website or mobile app, both of which are regulated by the Commodity Futures Trading Commission (CFTC). You can use this platform as a US resident if you’re aged 18+. However, it is either partially restricted or outright banned in Nevada, Michigan, Arizona, Massachusetts, Montana, Ohio, New Jersey, and Maryland.
When it comes to NBA prediction markets, this site has everything from game results, spreads, and props to awards, Championship Winners, and player trades. As Kalshi was the first prediction market site that remains one of the most popular, the trading volume is always high.
Trading volume regularly reaches eight figures for high-profile NBA games or prediction markets that involve big players like LeBron James. Even for the smaller markets, like Drafts and Mid-Season Cups, you’ll usually find five- and six-figure trading volumes in USD.
The NBA markets are resolved when the relevant game results or outcomes are confirmed by the official NBA website or ESPN, both of which are trusted sources. When trading event contracts at Kalshi, you pay a fee that’s based on the expected profits of your trade should your prediction be correct.
Polymarket has a US-specific trading app that’s regulated by the CFTC and has a headquarters in New York City. This app is separate from its international website and accepts traders aged 18+ in most US states. However, there may be partial or outright bans in some states, so check the T&Cs before you download the app and create your account.
On the app, you’ll find detailed NBA game props as well as player trading markets and all the usual futures. If you’re looking for a prediction market that will keep you going year-round, Polymarket has a dedicated “NBA Offseason” filter. Here you can find all markets related to players’ next teams, the NBA Draft, and even markets predicting the size of a high-profile player’s contract.
It’s also one of the best prediction markets for tracking tools. As well as graphics, there’s a written “Market Context” section that puts the data into words for you. Moreover, the order book is completely transparent, showing exact traders as well as the total volume.
Polymarket has a dynamic taker fee structure that starts at $0.03 and maxes out at $0.075 for contracts that cost $0.50 (50% chance). There are no maker fees, and there’s actually a maker rebate program that can get you up to 25% back.
Crypto.com offers NBA prediction market trading in the US via Crypto.com | Derivatives North America (CDNA) and its standalone OG app. Both of these are CFTC-regulated exchanges, so the platform accepts US residents aged 18+. However, the platform is outright banned in New York and Arizona, with sports prediction markets prohibited in Nevada, Ohio, Michigan, Maryland, Massachusetts, New Jersey, and Illinois.
While this site doesn’t have nearly as many NBA prediction markets as Kalshi and Polymarket, it still offers some advantages. The platform is stripped back with a very simple interface, which makes it ideal for first-time traders. Moreover, as the market selection is small, the trading volume is still usually very good relative to the user base of the platform.
Another thing that this site has to offer NBA event traders is a low and simple fee structure. You pay a flat rate of just $0.02 per event contract, which is waived entirely if you hold the contracts until the event’s conclusion. It doesn’t matter if you win or lose; you pay no fees as long as you don’t sell.
Finally, Crypto.com is the only prediction market site that offers $10 event contracts as well as $1.00 contracts. These are priced between $0.01 and $9.99 and pay out at $10 each if the associated prediction is correct.

NBA and all other forms of prediction market trading are risky activities. However, it does have the potential to add extra excitement to the sporting action.
To help you have as safe and fun a time as possible, we’ve put together these top five expert tips:
First and foremost, you should view NBA prediction markets as speculation and a hobby, not a financial investment. As we said above, there’s a very high risk of losing money, so there’s no world in which prediction markets should be viewed as a means to financially elevate yourself.
Following on from the point above, never deposit and trade using an amount of money that’s more than you can comfortably afford to lose. Then set aside portions of that total bankroll for multiple trades. Don’t use the full amount to buy contracts for one market.
Besides watching games, studying the stats, and keeping up-to-date with off-the-court news, you also need to track market opinion. Most prediction markets have some great tools for this, particularly Kalshi and Polymarket.
Sudden price drops or hikes in NBA event contracts are relatively common, but sometimes they can be caused by a market overreaction. For example, if a team wins a game by 20+ points, prediction markets like the spread and Over/under often get inflated, as does the price for the event contracts tied to the team’s win. If you learn to spot these, you can sometimes spot value and buy event contracts for a lower price. You also may be able to sell event contracts that you’re holding for an inflated price.
Last but not least, make sure that you make your trades based 100% on logic and what will happen. Never let emotion take over and buy event contracts tied to the team that you want to win. If you struggle with this, avoid markets entirely that are related to NBA teams or athletes that you actively support.
In summary, prediction markets enable you and other traders to buy and sell contracts that are tied to the possible outcomes of future NBA events. This includes games, playoffs, Championship Winners, MVP Awards, the NBA Draft, and more.
You can win money by making correct forecasts and lose money by making inaccurate predictions. As we explained, the three best prediction market platforms for NBA event trading are Kalshi, Polymarket, and Crypto.com.
Regardless of which one you choose, prediction market trading will always be a risky activity. Still, if you wish to give it a try, you can register on your platform of choice directly using the banners on this page.
Kalshi and Polymarket are tied as the two best prediction market sites for the NBA; both of these offer a massive selection of basketball prediction markets and have a massive trading volume. If you’re new to prediction markets, Crypto.com is a smaller but more user-friendly option with low trading fees.
On NBA prediction markets, you can trade event contracts that are tied to predictions of future NBA events. If you hold a position for a prediction that ends up being correct, you win a payout; if not, you lose money.
Event contracts are always priced between $0.01 and $0.99 before the future event has happened. Once it has been resolved, the contracts that correlate to the correct prediction go to $1.00, with the opposite numbers closing at $0.00. This determines if you receive a payout and a profit, or lose all the money you outlaid on the trade.
