Best Tennis Prediction Market Sites in 2026

Quick facts about tennis prediction market sites

• You buy and sell Yes/No tennis event contracts on prediction market sites.
• The prediction markets are peer-to-peer (P2P).
• Each tennis event contract settles at $1 if your prediction is correct.

Overview of tennis prediction markets

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:

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.

The best tennis prediction market sites

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 – Wide market range

Kalshi: Pros and Cons

• Regulated by the CFTC and has federal oversight
• Deepest markets and contract selections
• User-friendly website (PC and mobile)

• Legal scrutiny exists in certain US states
• Customer support can be slow during high traffic periods

Visit Kalshi

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.

Polymarket – Extensive futures prediction markets

Polymarket: Pros and Cons

• Crypto options available for international site
• Dedicated app for US members
• User-friendly platform

• Only 10 active video games markets

Visit Polymarket

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.

Crypto.com – Convenient for live trading

Crypto.com: Pros and Cons

• Low trading fees
• Wide range of prediction markets, including sports
• Simple Yes/No outcomes
• User-friendly app

• No welcome bonus for prediction trading

Visit Crypto.com

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.

Our review process for the best tennis prediction sites

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:

Compliance

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.

Tennis competitions

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:

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.

Available markets

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:

The prediction markets should be available both before and during the match.

Trading volume

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.

Usability

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.

Support performance

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.
