Tennis is undoubtedly a popular and highly-watched sport in the US. If you’re a fan of the lawn game, you can sign up on the best tennis prediction market sites to trade event contracts on different match outcomes.
Our best prediction market platforms for tennis are Kalshi, Polymarket, and Crypto.com. All three are available in several US states as they’re regulated by the Commodity Futures Trading Commission (CFTC). As you read on, we’ll share our review of the top sites, how the prediction markets work, and other details to know about tennis event contracts.
On a tennis prediction market site, you simply trade outcomes in the sport. The outcomes are represented by Yes/No event contracts, and you buy and sell them according to your predictions. Here’s an example of a game between Jannik Sinner and Carlos Alcaraz we saw during our review:
| Event | Yes contract | No contract |
|---|---|---|
| Sinner to win | $0.59 | $0.42 |
| Alcaraz to win | $0.42 | $0.59 |
The contracts usually cost between $0.01 and $0.99, and market conditions determine their prices. That means if more traders buy a particular contract, its value will increase, and vice versa. Due to trader sentiment, contract pricing is not fixed and the prediction market site does not set these prices.
If you predict correctly, each event contract pays $1. For instance, suppose you buy 100 contracts for Alcaraz to win at a total of $42. If he does win, you get paid $100, so it’s a $58 profit.
The way tennis prediction markets work is the same as for other sports. In our analysis of the best NFL prediction market sites, we also saw Yes/No contracts for football game results.
Tennis is popular, so finding a prediction market site that offers it isn’t difficult. That said, if you want the best, here are our top three:
Kalshi scored the highest rating among the prediction market sites we tested for outcome variety. On this platform, you can trade event contracts on the tennis game winner, spread, and total. In addition, Kalshi supports predicting aces, set winners, exact-match scores, total games, and futures.
We were most impressed by the aces and exact-match score options because they’re scarce on other prediction market apps. For context, aces let you trade on the outcome of which player will have the most unreturned, point-winning serves hit in a match. Meanwhile, the exact-match score involves predicting the precise final set count of the match.
When you visit the Kalshi tennis section, you’ll see the different prediction categories on the top row. The brand even displays the exact number of markets they contain each time. All you have to do is scroll and select your preferred option.
If long-term tennis event trading interests you, Polymarket is an ideal prediction market platform. To use Polymarket in the US, you have to install the iOS mobile app from the Apple App Store. You can’t trade on the website, and an Android app is still under development.
During our Polymarket review, we saw futures for almost all major tennis competitions. These include the four Grand Slams: Wimbledon, the US Open, the Australian Open, and Roland Garros. The prediction market app covers outcomes in men’s and women’s singles and doubles, plus mixed doubles.
On Polymarket, the primary futures are predicting which player will win the competition outright. However, you can also predict players to reach the final and whether a qualifier will reach the round of 16. If you want to trade on individual game outcomes, Polymarket offers moneyline, spread, total, set-winner, and completed-match prediction markets.
All three platforms on our list let you buy and trade contracts while a tennis game is ongoing. We rank Crypto.com as the best tennis prediction website specifically for its usability. If you’re a new or experienced trader, you’ll find the site and app convenient to use.
Once a tennis event begins, Crypto.com indicates it with a red live broadcast icon. You see a real-time gauge of each player’s chances to win, and the percentages change as the game progresses. Also, on the event cards, Crypto.com highlights only Buy buttons for both contestants, but they immediately change to Sell after you purchase.
Crypto.com also features in our best MLB prediction market sites because it’s also convenient for live trading in the National Pastime. That said, note that you can’t trade sports event contracts on the app if you’re in MA, MD, MI, NV, NY, and OH.
The tennis prediction market apps on our top list didn’t appear there randomly. Instead, we selected them after close testing and evaluating these factors:
For a prediction market platform to be available in the US, it must be regulated by the CFTC. Based on our research, CFTC compliance requires each site to have fair rules for settling contracts. Also, the commission mandates prediction market brands to protect your funds and personal data.
So we only rank sites that are confirmed to be registered with the CFTC. That said, the CFTC approves trading at the federal level, and state laws may differ. Therefore, you have to consider your local regulations before using a tennis prediction market site.
In our experience, most tennis event traders want Grand Slam prediction markets. We factor that into our reviews, while also checking for other popular tennis competitions. Here’s a full summary of the main tournaments we prioritize and when to expect them on the sites:
| Tennis tournament | When it happens |
|---|---|
| Australian Open | January |
| Roland Garros (French Open) | Late May to early June |
| Wimbledon | July |
| US Open | Late August to early September |
| ATP/WTA Finals | November |
| Summer Olympics | Played every four years |
This factor features in our rating process for other popular US sports. For instance, when choosing the best NBA prediction market sites, we looked for sites covering preseason, all-star weekend, playoffs, and finals, among other events.
A site that offers event contracts for just the tennis game winner isn’t worth your while. By our standards, the more markets for trading available, the better. On the best tennis prediction site, we expect to see at least 75% of these options:
| Market | Description |
|---|---|
| Moneyline | Pick who’ll win the tennis game |
| Total games | Predict whether the total games played will be over or under a specific number |
| Spread | Trade with a handicap on total games won for a player |
| Set winner | Choose who wins a particular set |
| Aces | Pick the player to score the most aces in a match |
| Exact match score | Predict the final score in sets |
| Tournament outright | Select a player to win the entire tournament |
The prediction markets should be available both before and during the match.
For this factor, we simply check how many people are buying and selling a tennis event contract. More traders mean higher liquidity, fairer prices, and faster order settlement. The difference between the bid and ask prices remains low, resulting in narrower spreads.
However, if there’s lower trading volume, you’ll experience high variance and spreads. Remember that the market is P2P. So, if you want to sell your tennis event contracts and there’s no one on the other end to buy, your trade gets trapped. Rest assured that the top brands we recommend have high trading volume and liquidity.
Tennis is quite a fast sport, as the ball often crosses the net in less than 0.5 seconds. As such, if it takes you a minute to find a prediction market for tennis, you may miss out during live trading. To avoid this, we rank only platforms with simple interfaces and fast load times. This factor considers both desktop and mobile usability, with more emphasis on the latter.
As a tennis prediction market trader, you may need assistance at any time. We recognize that and prioritize customer service testing in our reviews. For us, the best sites should offer 24/7 support via live chat and email, plus a detailed knowledge base or help center.
In our opinion, tennis is one of the most stats-heavy sports for prediction markets. When there’s a lot of data, you can research and execute relatively better trades. Here are our expert strategies to help you achieve that:
When predicting the game winner, compare players’ records on the current surface rather than their overall ranking. The reason is simple. A low-ranked player may perform much better on clay while a higher-ranked one struggles, but the market often focuses only on their positions.
In tennis, different weather conditions suit certain playing styles. To illustrate, the ball travels faster in hot temperatures, which favors big servers. Meanwhile, cooler situations are good for strong returners. You can consider this strategy when trading moneyline, totals, and set winner event contracts. During tests for the best soccer prediction market sites, we noted that weather also affects results in the sport. For example, rain can make the pitch slippery, causing mistakes in passing and shooting.
Here’s a tip to keep in mind during live tennis event trading. Looking at just the score on the prediction market site can be misleading because it doesn’t provide complete information. You should consider the game stats instead. Details such as first-serve percentage, first-serve points won, break points, and return points are more useful for live predictions.
Not all tennis games are ideal for prediction market trading. Drawing on our expertise, it’s ideal to avoid buying contracts when there’s high uncertainty. That can mean unknown injuries, low liquidity, and unpredictable weather. Simply put, don’t trade if you’re finding it difficult to make any reasonable prediction on the tennis event.
