The best NBA prediction market sites include Plus500, Kalshi, Polymarket, and Crypto.com. These platforms all offer an extensive range of in-game props and futures markets, alongside novelty contracts and player awards.
We've extensively tested a number of prediction markets sites to determine the best NBA options. This process has involved analysis of event coverage, market depth, and the available bonus offers.
You'll find our detailed findings below. This guide also includes expert trading tips and more information on how NBA prediction markets work.
Let’s start by reviewing our top four sports prediction market sites for NBA traders. Below, you can see a brief summary of our selections, while our mini reviews highlight each platform’s key features and selling points:
| 🏀 Basketball prediction market platform | 🔞 Age limit | 🧑⚖ Regulation | 🏆 Best for |
|---|---|---|---|
| Plus500 | 18+ | CFTCB | Beginners |
| Kalshi | 18+ | CFTCB | Trading volumes |
| Polymarket | 18+ | CFTCB | Offseason Markets |
| Crypto.com | 18+ | CFTCB | Simple Fee Structures |
Plus500 is our pick as the best NBA prediction site for beginners. You’ll find a range of informational guides based on prediction markets, for example, which cover everything from how to place a trade to key terminology such as liquidity, order book, and market resolution. The site has an intuitive and easy-to-use interface, too.
One of the site’s two main welcome offers is also straightforward and aimed at beginners. This comprises $20 in bonus funds, while the offers requires you to deposit and trade just $10 to claim. There are no market eligibility restrictions, either, so the bonus’s terms and conditions are easy to follow.
In terms of NBA coverage, you’ll find competitive outrights and match props at Plus500. This enables to trade outcomes both before and during matches, while you can pick the winner of the NBA Championship, too.
Currently, Plus500 is live in 45+ sports and regulated by the CFTCB. However, I was disappointed to discover that the platform charges 1.75% to process withdrawals across all payment methods.
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.
This platform 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.

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 “Yes” or “No” shares in a market that resolves in your favor, you’ll receive a payout. If you hold until settlement and the market turns against you, you’ll lose your initial stake. Remember, you can also sell open positions prior to settlement where demand and liquidity exists, helping you to manage risk and secure short-term profits.
Event contracts tend to be binary, meaning that there are Yes/No answers. In the case of NBA game outcomes, you’ll be able to pick the Away Team/Home Team to win. This type of trading is particularly popular in the NBA, where matches cannot end tied.
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 in this space:
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 ranges 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.
The price at which you buy shares also implies an outcome’s probability. For example, let’s say that you back Orlando Thunder to win the 2027 NBA Championship and buy “Yes” shares at $0.22. This implies a win probability of 22%, which is relatively competitive for an NBA futures market. If you hold this position and Orlando go on to prevail, your shares will resolve at $1.00 each and you’ll bank an ROI of 354.55%.
If you hold and the Thunder go on to lose, you’ll lose your stake in full alongside any trading fees you were required to pay. As I’ve touched on, you can also sell your shares depending on how the price performs, but I’ll expand on this in the next section of the guide.
As with all forms of trading, you can sell your event contracts as well as buy them. You can therefore sell open positions to your peers, depending on the prevailing levels of demand and liquidity. Here are the main reasons why you may want to sell your contracts before a market resolves:
Using the same example as above, let’s say that the Thunder embark on a long winning streak at the beginning of the regular season. Their “Yes” price subsequently peaks at $0.45, so you decide to sell and more than double your initial commitment. In this instance, you’ll bank a return of 104.55%, and this breaks down as follows:
Conversely, liquidity and your potential profitability will drop if the Thunder struggle initially and their price tanks to $0.12. In this case, you can manually execute a sell order at the real-time price, in a bid to cut your losses before the market resolves as $0.00.
There are three ways that you can buy event contracts for the NBA and other prediction markets. These include:
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% | $0.66 | $0.34 |
| Washington Wizards | 34% | $0.34 | $0.66 |
In this case, the Warriors are the favorites and have a 66% win probability. The Wizards are the underdogs and have just a 34% chance of winning, so backing them incurs a higher level of risk but potentially more significant return.
If your analysis shows that the true probability of a Warriors win is equal to or higher than 66%, you can buy “Yes” shares. You may then either hold until settlement or sell prior before the market resolves, depending on how the price fluctuates and if there’s enough liquidity. However, if your analysis shows that the Wizards boast excellent home form or have a penchant for starting games fast, consider backing them and selling once they’ve built an early lead.
Occasionally, you may find a discrepancy between the “Yes” price and implied probability value. This could be due to variances in the real-time bid-ask spread, liquidity and order book depth, and short-term arbitrage opportunities.
To trade on NBA games and events, you must be of legal age (18+) and a legal resident in a US state where the prediction market accepts players. TO verify this, you’ll be asked to provide your personal information and upload aligning documents to complete KYC.
These steps are slightly different on each platform, but the process is largely unchanged. Here’s a broad set of guidelines you can follow to create your prediction market account and buy NBA event contracts:

NBA and all other forms of prediction market trading carry inherent risk. However, trading also offers significant advantages over sports betting, especially when it comes to risk management and flexibility. To help you leverage these advantages, 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 perpetual risk of losing money, as even statistically likely outcomes are far from guaranteed. Even if you sell open positions or leverage loss limits, there’s the potential to lose capital or make only nominal profits.
Following on from the point above, never deposit and trade with an amount of money that’s more than you can comfortably afford to lose. Then, set aside a percentage of you total bankroll for individual trades. Don’t use the full amount to buy contracts for one market, as this increases your exposure to risk and chances of losing money.
It’s crucial that you inform your trades using performance data, including home and away form, scoring statistics, and head-to-head information. The key is to determine which datasets are most relevant to your chosen market or contract. You also need track live market movements and sentiment, as this may reveal further trading opportunities.
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 identify high value picks and buy event contracts for a lower price. You also may also be able to sell event contracts that you’re holding for an inflated price.
Whenever you open a trade, it’s important to understand the market and how prices may change. This will help you to create an optimal exit point for every open position, even if you initially intend to hold until settlement. This makes it easier to sell profitably while minimizing risk, or help you to limit losses on losing positions.
In summary, we’ve identified Plus500, Kalshi, Polymarket, and Crypto.com as the best prediction market platforms for NBA event trading. These sites offer excellent event coverage and market depth, whether you want to trade individual game outcomes or the winner of the NBA Championship.
These platforms also offer welcome bonuses for new players. However, they each have different layouts and fee structures, too, so I’d recommend that you compare them in detail before choosing where to trade. It’s also wise to compare probabilities and prices across different order books in real-time.
Regardless of which one you choose, prediction market trading will always carry the perennial risk of loss. This is why effective bankroll management is so important. If you wish to start trading, you can register on your platform of choice directly using the banners on this page.
Plus500, Kalshi, and Polymarket are tied as the best prediction market sites for the NBA. These platforms offer a broad selection of basketball prediction markets and have a large trading volume. If you’re new to prediction markets, Crypto.com is a smaller but more user-friendly option with low trading fees. Both Plus500 and Crypto.com are highly recommended for beginners.
On NBA prediction markets, you can trade event contracts that are tied to predictions of future NBA games and events. If you buy and hold a position for a prediction market that ends up being correct, your shares will be paid out at $1.00 each. If not, you’ll lose money and your initial capital commitment.
Yes, you can! All NBA prediction market sites allow you to sell your existing shares prior to a market being resolved, demand and liquidity permitting. This is an excellent way of locking in an early profit and minimizing your risk of loss. In some cases, you can even sell a percentage of your shares in order to cover your initial outlay or bank a nominal profit. You can leave the remainder riding on a particular outcome occurring.
When comparing prediction market sites for NBA trading, be sure to compare the quality of event coverage and market depth. Be aware of any fee structures that may be in place, too. I’d also recommend targeting sites with high trading volumes, as this tends to correlate with increased levels of liquidity.
Event contracts are always priced between $0.01 and $0.99 before the future event has happened. Once the market 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.
