Recently, sports prediction markets have become popular in the US, letting traders buy and sell contracts based on future sports outcomes. Instead of betting against a bookmaker, you’re matched with other traders taking the opposite position on each event.
On these sites, you can buy Yes or No contracts that pay $1 per contract if you’re correct or pay nothing if you’re not. Join us as we explain how prediction markets operate, the top options, our selection criteria, and how to maximize your experience.
From our experience, trading sports event contracts comes with some clear advantages, including access to major sports events. However, we did notice one drawback:
Just in case you’re wondering what a prediction market is all about, it’s a trading site where you can buy and sell contracts based on the projected outcomes of specific events. You can trade event contracts across categories such as sports, politics, and entertainment.
To participate, you select markets that match your interests and trade them using “Yes” or “No” contracts. For example, if you’re into sports, you might trade on College Basketball (M) contracts, like whether Tulsa wins by 5.5 points. Each contract shows the likelihood that a specific event will happen or not. Here’s an example based on who wins the NBA Championship.
Another thing to know is that contracts always come in pairs, so the market matches you with another trader taking the opposite position. One trader takes a “Yes” contract and the other a “No” contract, each valued at $1.
Many people assume that trading sports event contracts works similarly to sports betting, but the two are actually quite different. For example, sports predictions on Kalshi are possible because it’s an exchange and a prediction market that uses a peer-to-peer structure. This means traders match with each other, not with the site itself.
Unlike sportsbooks, where the site fixes odds, contract prices are set by the collective opinions of participants. Your position actively shapes the market, and prices adjust in real time to depict shifting trader sentiment.
Another key difference is the legal basis on which each operates. Prediction markets can function in states where sports betting isn’t allowed. This is because they’re regulated by the Commodity Futures Trading Commission (CFTC) under federal law, placing them in a different category from sportsbooks.
If you want to trade sports-event contracts, you’ll want to use the best prediction market sites. After conducting thorough research, we identified the top three licensed, secure, and reputable sites that offer major sports.
Here’s a quick look at our top picks and their app availability for trading sports-event contracts:
| Prediction markets for sports | App availability |
|---|---|
| Kalshi | Google Play Store and Apple App Store |
| Polymarket | Progressive web app |
| Robinhood | Google Play Store and Apple App Store |
Kalshi makes our top prediction markets list because not only does it feature major sports, but lets you create your own markets. If your market follows Kalshi’s guidelines and attracts public interest, it can be listed for others to trade.
Some of the popular sports featured on the site include football, basketball, soccer, racing, and esports. For example, in a College Basketball (NCAA) game between East Carolina and Michigan State, we bought a No contract on East Carolina covering 22.5 points. We purchased it for $1.95 with a $2 payout at a 97% probability. Moreover, you can also trade live on various sports events.
Polymarket impressed us with its variety of sports, offering up to 12 major categories, including football, basketball, hockey, tennis, soccer, UFC, Formula 1, chess, and cricket. Leagues such as the NFL, CFB, NBA, and NHL, as well as esports, are available. However, the site is currently still in a beta phase, preparing for a full public release soon.
On Polymarket, you can trade live or on future events. For example, in one of the future events, the NFC Championship, most traders favored the Los Angeles Rams at 32% at the time of our review, with Yes contracts priced at 33¢ and No at 70¢. Also, we found a Daily Rewards program that pays traders whose orders closely match the market price. Rewards show the size and accuracy of their trades.
You may know Robinhood for stock trading, but it has also been growing in popularity for event contracts. We found some interesting specialized sports markets that make trading on the site unique.
For instance, in Pro Football, there’s a Thanksgiving Day Combo market where you can predict the winners of two games at once. A Yes contract for Kansas City and Baltimore to win was priced at 47 cents. The site also covers College Football, men’s college basketball, professional basketball, professional hockey, racing, and soccer, with each sport offering a range of contract options.
When we set out to choose prediction markets that support sports event contracts, we focused on key qualities that affect safety, legality, accuracy, and overall trading comfort. These criteria helped us identify sites that handle sports outcomes responsibly and give traders a dependable experience. Here are the areas we looked into:
Our first concern was whether each site operates under proper oversight. We checked for approval from the Commodity Futures Trading Commission (CFTC), as this confirms that the market adheres to federal rules designed to protect traders.
Kalshi, Polymarket, and Robinhood all operate under this structure. On Kalshi, for example, we found certified listings covering multiple sports categories. Seeing this reassured us that the prediction market meets the needed compliance standards.
We also checked which sites support cryptocurrency, as some traders prefer digital payments for their speed and accessibility. Polymarket accepts USDC, which makes it suitable for traders who prefer on-chain deposits and withdrawals.
Kalshi also supports crypto payments and offers fiat currency options. Robinhood, on the other hand, only supports standard currency transfers. Traders who want crypto-based funding can choose Polymarket and Kalshi, while those who prefer bank-linked transfers may choose Robinhood or Kalshi.
During our research, we limited our picks to prediction markets that present real-time probabilities for sports-related event contracts. This means the sites must update their numbers as real-world conditions change, including team news, injuries, gameplay updates, and shifting public positions.
To confirm this, we observed how each prediction market adjusts its market percentages. The best ones react almost immediately to new information, giving traders a current view of each sports outcome instead of stale indicators.
We also checked how many sports categories each site supports. Our goal was to avoid prediction markets that focused on only a handful of sports topics. We placed focus on major sports such as football, soccer, and basketball. These categories consistently appear on our recommended sites, allowing traders who join to access the most popular competitions and events.
Convenience was a major factor for us because sports probabilities move quickly. We wanted sites that make it easy to check markets and make decisions at any moment.
Kalshi and Robinhood offer dedicated mobile apps, providing traders with instant access to their accounts. Polymarket doesn’t have a standard mobile app available in the Google Play Store or Apple App Store, but it does offer a progressive web app (PWA). This PWA functions similarly to a regular app. It also keeps you logged in directly from your home screen without requiring a browser to be opened.
This type of access matters because probabilities can shift suddenly during game-related updates. Quick entry into your account helps you decide whether to lock in gains or adjust your position before the market moves again.
It’s essential that prediction markets conduct the necessary identity checks before traders can access their service. That’s why we paid close attention to whether these sites perform proper KYC verification for every trader. Kalshi, Polymarket, and Robinhood all follow this procedure. We completed the verification steps on these sites and confirmed that they request the correct documents, including government-issued identification and proof of residence.
KYC prevents people from accessing the site from regions that aren’t approved. It also ensures that only individuals who meet the required age limit can open an account.
If you’re wondering how to avoid unnecessary issues when using a prediction market, here are the practical steps we follow anytime we trade on sports using these sites. They’ve helped us avoid mistakes that could disrupt our experience.
Always begin by checking the terms and conditions of any prediction market. This page provides a clear overview of how the site operates and the expectations placed on traders. For example, when we reviewed Kalshi’s terms, we learned that traders are expected to pay the charges listed on the site. Details like this matter because they affect how you approach each contract. You can also confirm the exact expiration time for a contract within the contract rules, which is crucial before entering any position. Besides, make it a habit to regularly revisit the site’s terms and conditions page. Updates happen, and staying informed keeps you on the right side of the rules.
If you’re interested in sports-related contracts, it helps to see what traders are actively reacting to. Market activity shapes contract prices, so taking a quick look at trending topics gives you a sense of what people are focusing on. When we checked, it helped us decide which events to trade or consider.
When something seems unclear, reach out to the prediction market support team first. They usually respond within a short window, often under 24 hours, and they give direct answers that help you avoid confusion.
Most prediction markets also feature community spaces, such as chat rooms. Although those can be helpful, they shouldn’t be your first stop whenever you need clarity on a rule or system issue. It’s better to confirm official details straight from the site.
New traders shouldn’t rush into placing large amounts right away. Begin with small positions, even $1 is enough to understand how contracts move. Gradually increase your activity as you get comfortable with the site’s structure.
Also, stick to contracts related to topics you understand. This makes it easier to judge whether a “Yes” or “No” contract aligns with real-world conditions. You can also read prediction markets news to gather more details before deciding. Remember, prediction markets accurately depict real-world situations, particularly in sports and current events. Staying informed with trusted news sources helps you make more informed decisions on each contract.
One thing we’ve learned from using prediction markets is that timing matters just as much as the contract you pick. Every market moves based on trader behaviour, news updates, and changes in real events. Hence, you need to recognise when it makes sense to increase your position and when it’s better to step back.
The moment a contract begins to move in your favour because new information supports the outcome you selected, you might decide to add a little more to strengthen your position. This works best when the trend is still forming, not when the market has already reacted fully. For instance, if a key update breaks in a sports event and you can confirm that it supports your earlier choice, increasing your position early can help you stay aligned with that direction.
On the other hand, know when to cut back. If the contract starts shifting against your expectations and the news no longer supports your initial decision, there’s no point holding on still. Reducing your position early can help you avoid being stuck in a trade that no longer depicts the real situation.
From our review, we found that Kalshi, Polymarket, and Robinhood rank among the most reliable sites for trading sports event contracts. We based our selection on clear criteria, beginning with legitimacy. All three sites operate under the oversight of the Commodity Futures Trading Commission (CFTC), which helps ensure that each market follows the required rules.
We also considered payment options. Kalshi and Polymarket support cryptocurrency, giving traders broad funding choices. Those who prefer fiat can use Robinhood or Kalshi, since both accept traditional payment methods. Our selection also focuses on sites that cover major sports such as football and basketball, giving you wide event options to trade on. Plus, each prediction market either provides a mobile app or a progressive web app, allowing you to trade comfortably on your phone.
Kalshi is a top pick if you want access to major sports and the freedom to build your own market. Polymarket also features popular sports and includes a daily reward, which is rare among prediction market sites. Robinhood offers a clean way to trade sports event contracts as well. At the moment, Kalshi and Robinhood are fully accessible to US residents, while Polymarket is in a testing stage.
To get the best experience, read each site’s terms and conditions along with the rules for the contract you want to trade. Check what’s trending before choosing an outcome, contact customer support for any clarifications, and focus on sports topics you understand. Also, know the right time to increase or reduce your position.
