How do tennis prediction markets work?
Tennis prediction market sites let you trade contracts based on the outcome of specific match events. These contracts can cover everything from who will win a match to whether a player will win a set or reach a certain number of games.
Prediction markets ask simple binary questions and you just have to choose a contract that aligns with your prediction. If you believe an event will happen in the real world, you buy the Yes contracts. If you don’t, you go for No contracts. For example, a market may ask whether Carlos Alcaraz will beat his opponent in an upcoming match. You can buy a Yes contract if you think Carlos Alcaraz will indeed emerge as the winner of the match or take No contracts if you believe he won’t.
Contract prices usually range between $0.01 and $0.99 and they’re a good indication of what traders think the probability of an outcome is. If a Yes contract is trading at $0.75, it suggests the market, which means other traders, view it as having a 75% chance of happening. These prices aren’t static though, and they can change as more users make trading decisions.
After the event settles, which means after it happens, each contract is worth $1 if your prediction is correct or $0 if it isn’t. If you purchased a Yes contract at $0.75 and the event happens, your contract would settle at $1, and you’ll make a profit of $0.25 per share. If it doesn’t happen, you lose the $0.75 spent on purchasing each contract.
You don’t have to wait until the event happens, though. At the
best prediction markets, you can choose to sell your position earlier at the current market price if things aren’t going the way you predicted or if you want to realize a profit. This depends on the liquidity of the market.
Here are a few prediction markets and their implied probabilities.
| Prediction market | Chance | Yes contract price | No contract price |
| Will Aryna Sabalenka win the 2026 Women’s US Open? | 29% | $0.29 | $0.74 |
| Will Jannik Sinner win the 2026 Men’s US Open? | 55% | $0.55 | $0.46 |

The best tennis prediction markets to have on your radar
After putting reputable prediction market platforms through their paces, three emerged as the top options for tennis predictions. It’s no surprise that these brands are currently among the industry leaders. Let’s take a look at what makes Polymarket, Kalshi, and Crypto.com the best choice for tennis prediction markets. Do remember that sports prediction markets are currently not allowed in Nevada, Ohio, Michigan, Maryland, Massachusetts, New Jersey, and Illinois.
Polymarket – best for tennis tournament winner markets
Polymarket: Pros and Cons
- Plenty of prediction market topics
- Trending and breaking areas of interest
- Lots of predictions in all major subject areas
- User-friendly site design
Polymarket is a prediction market giant that returned to the US in late 2025 after securing a license from the CFTC. And from our experience, this platform offers the most extensive selection of tennis prediction markets, which are well suited to expert traders and beginners alike. The site and app are incredibly easy to use, and it’s got robust coverage of markets with contracts from major tournaments like the US Open, WTA 1000 Toronto, and the Miami Open.
Top prediction markets include who will be the 2026 Women’s US Open Winner and ATP 1000 Montreal: Winner.
What’s more, there are simple guides to help you get the hang of things if you’re totally new to these markets. Veterans in this space will also find a range of analytics tools and live trackers that could help you make better trading decisions.
Polymarket is built on the Polygon blockchain and uses pUSDC for its trades. If you don’t already hold crypto, you can still fund your account through third-party providers like MoonPay using a debit card, credit card, Google Pay, or Apple Pay. If you want more variety, Polymarket is also one of the
best WWE prediction market sites
with dozens of events to trade on.
Kalshi – best for live tennis prediction markets
Kalshi: Pros and Cons
- Find markets via search facility
- Extensive range of prediction markets
- Clear fees system
- Large help center
- Limited promos for existing customers
There’s no list of the best prediction market sites for just about any future event that doesn’t include Kalshi. Kalshi has almost the same number of active markets as Polymarket, but the variety is impressive. Depending on the season, you’ll find tennis prediction markets on the Grand Slam tournaments, with the Australian Open, French Open, Wimbledon, and US Open all featured. ATP and WTA Tours are also covered alongside ITF, Challenger, and doubles markets.
Kalshi prediction markets are categorized too, so it’s easy to get straight to a market you prefer. We also enjoyed using the combo feature to combine our predictions across at least two markets.
At the time of writing, Kalshi also had several live markets, and they usually have excellent liquidity too, which makes it easier to sell your position before the match ends.
And if you enjoy trading on the move, the Kalshi app is ranked as one of the best
sports prediction market apps, and you can download it on your Android and iOS devices. If you’re yet to register at Kalshi, you can visit the site using our on-page banners and create a new account to receive a welcome bonus of $20 in trading credit after you’ve made a first deposit of at least $10 into your account. A few other rewards are available to returning users too.
Crypto.com: Pros and Cons
- Sports, elections, culture, and economics markets
- Low commission for trading
- Supports USD and cryptocurrency payments
- No crypto prediction markets
Crypto.com is a top choice to consider if you’re looking for the best tennis prediction market sites that are great for new traders. This brand is well known as a crypto exchange giant, but it added prediction markets late last year, and sports make up the most of this.
We found a good number of prediction markets spanning the Grand Slam, ATP, WTA, and ITF sporting events. The prediction trading hub offers daily trading opportunities on scheduled and live matches, as well as tennis futures. Its futures markets aren’t as extensive as those on Kalshi or Polymarket, but its live matches hold up just fine.
Despite its name, you can fund your account using fiat if you don’t already hold crypto. The Crypto.com app and website interfaces are also easy to navigate, and there are tutorials and articles in the Learn section to help you get started if you’re totally new to these markets. Crypto.com is off-limits to traders in Arizona and New York.

What tennis prediction markets can you trade?
Tennis prediction markets are quite extensive and cover a lot more than who wins a match. We could trade on the outcome of events across the ATP, WTA, ITF, Challenger, and Grand Slam, plus doubles events too. Similar to our experience while reviewing the
best Formula 1 market sites, the available contract types also vary based on the current sporting season, but these are the main ones we found.
Here, you’re simply guessing which player you think will win the match, regardless of the final score. Match winner contracts are often available even before the match begins.
Do you think a certain player will win a particular set rather than the entire match? You can trade on this real-life outcome too. Remember that you’ve got the choice to sell if it starts going against your initial predictions.
🔢 Exact match score markets
If you’re very knowledgeable about tennis and want to put your skills to the test, you can try out the exact match score prediction market. As the name implies, you’ll be predicting the exact number of sets each player will win. For example, you could choose a player to win 2-0 or 2-1 in a best-of-three match. Wrong predictions resolve as $0, so only spend what you’re comfortable losing.
Instead of choosing a player, you can simply predict whether the total number of games will finish above or below a stated figure. This is usually a good starting point for beginners, since it isn’t as complicated as other prediction markets. For instance, you can speculate whether a match will have over or under 21.5 games.
These markets are all about an individual player’s performance. The options can include whether a player wins a set, reaches a stated milestone, or hits a particular milestone.
🏅 Tournament winner and futures markets
Futures cover longer-term markets such as events that will happen later in a tournament or season. We spotted prediction markets on who will win an ATP or WTA tournament, and whether a particular player will lift the Grand Slam trophy.
If you enjoy the excitement of making predictions as a match unfolds, live prediction markets are right up your alley. These markets can be unpredictable, and contract prices can change quickly as players win sets, break serve or get injured.
The
best soccer prediction market sites
also let you combine two or more tennis predictions in one trade. You could combine a match winner with a spread, total-games contract, or another available outcome that catches your fancy. There’s usually a ‘Combo’ or ‘Build a Combo’ option on the screen and you can select no fewer than two markets to get started.
Features to look out for when choosing the best tennis prediction market sites
To get a well-rounded experience, it’s always better to prioritize brands that go all out to offer the best services. Here are some of the criteria we checked when choosing the right brands to trade on. We also looked at the same features when choosing the
best MLS prediction market sites.
Licensing and security
All reputable prediction market platforms are regulated by the Commodity Futures Trading Commission (CFTC), and these are the brands you should register with. The CFTC ensures these sites adhere to strict standards on transparency and fairness for all traders. Additionally, security should be treated as a priority. The top platforms only let you trade after you’ve verified your account. This is important to keep fraudulent parties from accessing the site. What’s more, the prediction markets sites and apps should use security features such as SSL/TLS encryption, Two-Factor authentication checks, and biometric login features.
A wide range of tennis prediction markets
This is a major deciding feature. Aside from match winner contracts, you should have access to a wide range of tennis markets spanning set winners, exact match scores, total games, spreads, futures, props, and live events. The site should also cover ATP, WTA, ITF, Challenger, Grand Slam, and doubles matches.
Mobile optimized sites and nifty apps for on-the-go trading
Tennis prediction markets can be fast moving, and no one wants to get caught out by not selling their positions if the prices aren’t favorable. Your preferred site should be easy to use, and apps are a plus in our books.
Bonuses
All three brands we’ve recommended have offers for new traders alongside other rewards like liquidity and referral offers for returning traders. Although these sites aren’t big on bonuses, there are cool extras when available.
Reliable support
Things don’t always go as planned, and when this happens, you’ll need fast help. So we looked out for sites with 24/7 live chat, email, and searchable FAQ sections. Live chat is the best option if you have urgent queries. Emails and detailed FAQs are also helpful.
The best tennis prediction market sites are federally regulated, but their availability depends on where you live. This is because sports contracts aren’t available in all 50 states, with exceptions such as Nevada. You also need to be at least 18 years old to sign up.
With that being said, here’s how to sign up at any of our three recommended sites and start making your tennis predictions.
