Best Prediction Market Sites in May 2025
Best prediction market site in May 2025
What are prediction market sites?
Prediction market sites are legal alternatives to traditional sportsbooks — such as FanDuel, DraftKings, and Caesars Sportsbook — that are available in most U.S. jurisdictions in 2025. Prediction-based platforms act similarly to the stock exchange, allowing you to buy, sell, and trade event contracts on sports and various real-world events with other users. You only have two options to wager on for each contract — 'Yes' or 'No'.
Users set the price on the best prediction market sites, as each contract opens even odds and moves based on the public's action.
Top prediction market platforms reviewed
Prediction market sites are the hottest newcomers to the online betting sites industry. With dozens of operators emerging on the scene lately, we've cut through the clutter to bring you the three best prediction market sites available in May 2025:
1. Kalshi - Best overall prediction market site
$10 Bonus
Code: COVERS
Pound-for-pound, no other prediction site compares to Kalshi in 2025. Kalshi was one of the first predictive platforms to launch and has quickly become one of my go-to's when trading big sporting events, such as the ongoing NBA Playoffs and the upcoming NFL season. I also love how Kalshi covers real-world events outside the sports world, typically posting markets on relevant topics like 'Who the next Pope will be' or 'When will Donald Trump impose tariffs' faster than its competitors.
Where Kalshi wins and fails
Kalshi offers a wide range of prediction markets for various events, including sports, politics, pop culture, climate, tech and science, and more.
You can score a $10 bonus by signing up with the Kalshi promo code 'COVERS', making a $1 initial investment, and trading at least $100 in event contracts.
Kalshi's 'Predictive Insights' feature provides the entire forecasted price history for every event contract, allowing you to easily see if you are buying, selling, or trading at a lucrative time.
We wish Kalshi offered 24/7 customer support to help assist those new to prediction market sites.

2. Crypto.com - Best crypto prediction platform
$50 Bonus
As the name suggests, Crypto.com is the perfect predictive platform for all cryptocurrency enthusiasts, supporting more than 350 altcoins, including popular vendors like Bitcoin (BTC), DogeCoin (DOGE), and Ethereum (ETH).

Where Crypto.com wins and fails

Crypto.com prioritizes user safety, utilizing encryption, two-factor authentication, and cold storage of your cryptocurrency to protect your personal and financial data from hackers.
Despite not having a dedicated sports betting app, the general Crypto.com app is perfectly optimized for mobile predictive betting.

"I used to LOVE this app. It has a very beginner-friendly platform and has low transaction fees, BUT I have now been waiting THREE DAYS for a response on the chat, the ONLY way to reach anyone. Update: Was glad to have finally reached a "human" only to find out that "sarah" was, in fact, a bot too. Update #2: I would like to say, a year later, whatever problems I encountered before, I can happily say have been eradicated. The app is very user-friendly and very reliable! Good job on the fixes."

3. Robinhood - World-class trading platform
Up to $200 in Reward Stock
Robinhood steals the final podium spot on our list of best prediction market sites in 2025 due to the potential we see in the platform. While only dipping its toes into predictive-based contracts during the 2024 U.S. Presidential election, Robinhood Market Inc. is a commission-free stock trading and investing operator that has provided U.S. users with a world-class platform for over a decade. We'd suggest buying into Robinhood today, as we believe it can be one of the biggest names in the industry for years to come.
Where Robinhood wins and fails
Robinhood only applies a $0.01 fee on all of its sports trades, which is by far a better house edge than you'd receive at traditional sportsbooks.
Established and trustworthy brand you can wager with securely.
You don't need a Robinhood promo code to unlock up to $200 in reward stock upon registering a new account.
Robinhood must offer markets on top sporting leagues like the NFL, NBA, and NHL to compete with other prediction market sites.

"It's GREAT! I have other investment apps but Robinhood seems to be the best one, as the colors and layout (UI) are better than the competition."

Other sports betting prediction sites
- PredictIt: A New Zealand-based online prediction betting site that launched in November 2014. Unfortunately, PredictIt has yet to enter the sports trading world, only offering 16 predictive markets associated with U.S. politics in 2025.
- Polymarket: A crypto-based prediction platform that allows you to buy and sell shares on the outcome of future events.
How to choose the right prediction market site
Any of the three best prediction market sites listed above are great options, but we've outlined several aspects to consider when evaluating what the right predictive platform is for you:
🏆 Market size: Consider the prediction markets you prefer to wager on. Do you want to buy, sell, and trade contracts on the hottest sporting events, such as the Super Bowl? Or, are your interests outside of sports? If so, ensure your chosen prediction betting platform offers markets on politics, pop culture, and other real-world events.
💰 Bonus offers: The best prediction market sites, headlined by Kalshi, offer lucrative sportsbook promos to grow your bankroll quickly. We strongly advise reading the terms and conditions for each offer carefully before claiming to ensure you can maximize the bonus.
📊 Odd value: Similar to traditional sportsbook betting odds, the market value for a particular contract can vary from one online predictive site to another. Line shopping is a crucial step before investing in any predictive contract.
💸 Speedy payouts: How quickly can you get that green back into your hands? Getting your winnings in a timely fashion should be one of the most important reasons you select a particular platform.
How to sign up with prediction market sites
Signing up with the best prediction market sites is quite similar across operators, allowing you to register a new account in minutes when you follow these steps:
Select your prediction sites
With new betting sites constantly emerging in the prediction platform space, you'll want to browse the available options and select only operators that align with your trading preferences.
Register and verify your identity
You'll have to create an account with each of the best prediction market sites you've chosen. This can be done on desktop or mobile app, if the platform has one. Simply provide some personal details — your full name, home and email address, date of birth, etc. — when prompted to complete your profile. It's worth noting that some predictive sportsbooks may require your Social Security Number (SSN) and a government-issued ID (driver's license, passport, etc.) to verify your identity.
Claim a bonus
If a prediction market site offers a welcome bonus — like Kalshi's $10 bonus offer you can claim with the bonus code 'COVERS' — now is the time to input the Covers-exclusive promo code and claim the offer. Failure to do so now will not only avoid the existing welcome bonus but also prohibit you from claiming any future new-user promos the operator offers.
Deposit
Now, you must add funds to your newly created prediction site account. Go to the cashier page, enter your banking information, and submit your first deposit.
Start trading
It's time for the fun part — start buying, selling, and trading event contracts! Unlike traditional online sportsbooks that offer familiar betting markets like point spread, moneyline, Over/Under (totals), and parlays, you'll find markets that allow you to wager on the predictive outcome of a particular event, such as 'Who the next Pope will be'. These markets resemble traditional futures wagers, as you must wait for the event to conclude before knowing if your bet won or lost.
Most of the best prediction market sites allow you to buy, sell, or trade contracts until the selected event ends, mimicking live betting that you'd find at traditional sportsbooks.
Withdraw
When you're ready to receive your funds, head back to the cashier, select 'Withdraw', enter the amount, choose your preferred banking method, and hit 'Confirm' to finish the process. The best prediction market sites should issue your money within an hour, but certainly within a day of request.
How does sports event trading work?
Prediction market sites operate as trading platforms, allowing you to buy, sell, and trade contracts for available events. Here's how it works:
- Can only pick 'Yes' or 'No' for any event. You cannot hold contracts for both sides of an event.
- Prediction market platforms cap the number of contracts you can have for a single event. For example, Robinhood's maximum limit is 500,000.
- The market price for each side of an event is determined by supply and demand from users, as the public's backing will alter how much a contract will cost.
- Can buy, sell, or trade contracts until the final buzzer for all events.
Event Trading on Kalshi
While many of the best prediction market sites have recently expanded to the sporting world and offer contracts for top events like the NBA Playoffs, NFL Draft, and Masters golf tournament, you can also trade contracts for political, pop culture, or various other relevant events, such as 'Who the next Pope will be'.
US sports betting resources
Are prediction market sites legal?
Yes, prediction market sites are legal. Single-event contracts are not traditional sports bets, so prediction market sites are not regulated like conventional sportsbooks. Instead of being authorized at the state level, federal agencies like the Commodity Futures Trading Commission (CFTC) and Securities and Exchange Commission (SEC) regulate prediction market sites and their contracts like they would regulate stock-exchange platforms.
The best prediction market sites on this page are available in the following U.S. states as of May 2025:
Several U.S. jurisdictions — Illinois, Maryland, Montana, New Jersey, Nevada, and Ohio — have recently taken a stand against prediction platforms, sending cease-and-desist orders to various operators to outlaw this type of online sports betting.
Free vs. Paid prediction market sites
Most tools and data on prediction market sites are available for free. For example, Kalshi's API service is free to join and unlocks in-depth information about specific market history and insights into your personal portfolio.
However, many of the best prediction platforms offer various paid services, giving you access to more extensive data pools, detailed breakdowns, and advanced insights into relevant trends. Robinhood Gold, for example, provides various benefits to help your trading, such as increased instant deposits, exclusive market data from third-party companies, and more for an annual or monthly subscription cost.
The extra data you receive from these paid prediction market site tools can be helpful, but ultimately, it’s a case-by-case thing. Some traders find it worth it, while others don’t. We recommend doing your research to confirm precisely what data is available in paid plans before signing up.
The role of AI and data analysis in predictive trading
While analytics has become a fixture of the sports world, helping NFL and NBA coaches make crucial decisions throughout a game, artificial intelligence — often referred to as AI — is becoming increasingly common within the prediction market industry.
Traditional betting sites use machine learning to decipher complex AI algorithms to analyze years of data, trends, and other pertinent trading information in seconds to help set market prices.
But, it's not just the online operators benefitting from AI. Prediction market users can use AI-powered platforms to access these same predictive models to identify market inefficiencies to help influence their pre-event decisions. As an event unfolds, the best prediction market sites offer real-time AI-powered insights to assist with live trading, letting you know if you should buy or trade more contracts. Some AI-powered tools even scan social media to determine their outlook on an event based on the public's perception.
Predictive betting news
How sports betting prediction models work
The best prediction market sites offer speculative-based 'Yes' or 'No' contracts on various sports events — such as 'Who will win the 2026 Super Bowl'. You choose which side of the event you want to buy, as most prediction sites pay you $1 for every contract you own. You can also trade contracts with other users until an event ends, allowing you to double down or cash out early on your position.
For example, if you own five contracts on 'Who the next Pope will be' that you bought for $0.50 each ($2.50 total), the prediction market platform will pay out $5 if you win, which is a $2.50 profit. It's important to invest in an event early, as your returns will be smaller the more you pay for a contract.
Prediction market sites vs. traditional sportsbooks
We've outlined how prediction market sites and traditional sportsbooks are similar and different in 2025:
Market size
Prediction market platforms only offer two options for every event — 'Yes' or 'No'. This far lacks in comparison to traditional online sportsbooks.
Regular online sports betting sites also offer more sports markets than prediction-based operators, who typically only offer contracts for the major North American leagues like the NFL, NHL, and NBA.
Odds value
Traditional online sportsbooks set their odds using an algorithm based on historical data, current betting patterns, and pre-set house edges. Meanwhile, prediction market sites rely only on the supply and demand of a contract based on traders' interest to set their prices, which typically leads to better value and higher profits for users.
Transparency
Anyone can browse the current market price for any event offered at the best prediction sites. You can see how much money has been wagered on an event and track how the market value has changed over time, which is information that traditional sportsbooks typically keep under wraps. This level of transparency is greatly beneficial for traders in their decision-making progress.
Regulation
Traditional online sports betting sites require approval via state-issued sports betting licenses to offer legal services. In contrast, the best prediction market sites bypass state laws, only requiring approval from federal agencies.
Covers Expert AnalysisPrediction market sites FAQs
Yes, Prediction market sites are legal in most U.S. states today. However, several states — Illinois, Maryland, Montana, New Jersey, Nevada, Ohio — and federal regulators have recently challenged multiple top prediction market sites over individual business practices and have prohibited them from offering online sports betting services.
In our opinion, Kalshi is by far the top prediction market site for trading sports in 2025.
Prediction betting sites' markets are set by users rather than the site itself, meaning that the supply and demand of an event contract determines its price. Meanwhile, traditional online sportsbooks use a mixture of AI-drive data and historical trends to set their odds.
Similar to traditional sportsbooks, the amount you can earn wagering with the best prediction market sites depends on you.
Yes, the best prediction market sites are better than traditional sportsbooks for several markets, such as presidential elections and the NFL Draft. Many states do not allow sportsbooks to offer wagers on these markets. However, it is entirely legal to sell prediction contracts for these events.
Every best site for prediction markets has different odds varying from event to event, meaning no operator consistently offers the most accurate predictions. However, we found that Kalshi is the best overall prediction site for fair odds.
