Major League Baseball (MLB) is one of the Big Four sports leagues in the US, so it’s popular all over the country. In MLB prediction markets, you can trade event contracts related to outcomes in the baseball league’s events.
Several prediction market sites that feature MLB games are available in the US, but we want you to only use the best. Therefore, we tested and selected the top three, which are Polymarket US, Kalshi, and Crypto.com. Read on to understand how these platforms work and the baseball event contracts available for prediction trading.
Top Sports Prediction Sites for MLB in July
Quick facts about baseball prediction markets
- Baseball prediction markets offer MLB event contracts for trading.
- The sites are allowed in the US because they’re CFTC-regulated.
- You can predict the game winner, totals, spreads, futures, and more.
How prediction markets for the MLB work
When you register on an MLB prediction market platform, you’ll see event contracts for various MLB games. They’re featured as Yes or No questions, and you select one that suits your prediction. These contracts cost between $0.01 and $0.99, and you get a $1 payout for each if your prediction is correct.
The event contract prices are determined by supply and demand, meaning the prediction market sites don’t assign them directly. The prices you’ll see in sports prediction markets are based on traders’ overall sentiment and are affected by real life factors such as the latest news, player status, and even the weather updates, potentially.
Trading MLB event contracts
Let’s use this Dodgers vs Phillies MLB game we found during our review as an example:
| Event contract | Price |
| Dodgers to win | Yes @ $0.47
No @ $0.54 |
| Phillies to win | Yes @ $0.54
No @ $0.47 |
Purchasing 100 Yes event contracts for the Dodgers to win against the Phillies will cost you $47 ($0.47 each). If the team eventually wins, you’ll get paid $100 ($1 for each contract), meaning the profit is $53. That’s how simple it is to trade in MLB prediction markets.
The event contract prices also reflect probabilities because they’re set by the market. For instance, Yes @ $0.54 for the Phillies means traders collectively believe the team has about a 54% chance of winning. However, the prices don’t always add up to 1 or a 100% probability because of bid-ask differences.
The best MLB prediction markets in the US
We’ve mentioned Polymarket US, Kalshi, and Crypto.com as our best prediction market platforms for the MLB. Here are our reviews of each site and where they stand out:
Polymarket US – Best for combos
Polymarket: Pros and Cons - Numerous markets on sports, crypto, the economy, and politics
- Regulated by the CFTC
- Multiple rewards for existing traders
On the Polymarket US app, you can trade MLB combo event contracts. This option lets you combine multiple predictions into a single position, and you get a relatively higher payout if all are correct. As such, it’s ideal if you don’t want to trade on single outcomes.
You can build your own combos from the featured Polymarket MLB prediction markets. Alternatively, the platform has pre-made combos to choose from. For instance, we found customized combos such as Favorites, Run line multi, Daily diamond mixed, and First innings fireworks.
Therefore, the combos cover several Polymarket sports markets for the MLB. Each one can include 3, 4, 5, or 6 picks, and you just have to tap on any you prefer to trade. As a new Polymarket US prediction market trader, you can claim a $50 welcome bonus. The offer requires a $20 minimum deposit, and you can use it to trade event contracts on MLB games.
Kalshi – Best for market variety
Kalshi: Pros & Cons - Broad range of markets
- 24/7 live chat support
- Huge reputation
- Native mobile app
The range of Kalshi MLB prediction markets is extensive from our checks. If you visit the site, you’ll find the options within the pro baseball category under Kalshi sports markets. Our firsthand count confirms that there are over 12 different subcategories to choose from when trading.
Kalshi supports game results such as the winner, spread, and total. Beyond those, you can trade event contracts for player props like home runs, strikeouts, hits, total bases, and RBIs. Futures are not left out, as you’ll find options to predict the MLB champions, playoff qualifiers, series matchup, and more.
One of the more unique markets we saw on Kalshi is the Player Debut. It lets you predict what date drafted players will make their MLB debut. Thanks to the many market options on Kalshi, you can count on the platform for trading on outcomes you understand better.
Crypto.com: Pros and Cons - Welcome bonus
- Broad range of markets
- High-performance mobile app
Crypto.com gets our recommendation if your primary interest is in future baseball predictions. We rate the site because it covers all the main options and makes them easy to track. Once you switch to the futures section, you’ll see a real-time count of the number of days before the event happens.
Let’s consider the MLB Champion prediction markets as an example. At the time of our review, Crypto.com indicated that the outcome was 104 days away from settlement. The site offered Yes/No event contracts for all 30 competing teams in the pro baseball league. When we checked Crypto.com’s NFL prediction markets, it was similar.
Away from the league champion, we counted 14+ other MLB future prediction markets on Crypto.com. These include the National League Winner, American League Winner, NL West Winner, and AL Central Winner, to name a few. Individual awards such as MVP, Rookie of the Year, and Cy Young Winner are also available.
Sponsored by Crypto.com – Not investment advice. Trading prediction markets and crypto involves risk, including potential loss of your stake. Consider your risk tolerance before participating. Crypto.com connects U.S. users to CDNA (regulated by CFTC) for derivatives trading. CDNA membership required. Trading may not be suitable for all—you could lose your entire investment plus fees. Past performance doesn’t guarantee future results. This is not a solicitation or recommendation to trade.
Is it legal to trade MLB event contracts?
The top MLB prediction market sites we recommend are regulated by the Commodity Futures Trading Commission (CFTC). As a result, they operate legally in the US. However, whether you can trade event contracts on them depends on your location.
Based on our reviews, prediction market brands usually exclude a few states from trading. Let’s take Crypto.com as an example. The brand excludes Ohio, Michigan, Maryland, Massachusetts, New Jersey, and a few other states from accessing baseball event contracts.
Therefore, consider your location to know whether you can legally trade on any prediction market site or app. It’s not just the MLB, but also the NFL, NHL, and NBA prediction markets, plus all other top leagues.
Tips for trading baseball prediction markets
As experts in MLB prediction market trading, we advise paying attention to these tips:
🔍 Review the starting pitchers
An ideal way to know how well an MLB team will perform is by checking the starting pitchers. These players have a big influence on the overall outcome of each game, so analyze their recent performances. Stats such as ERA, WHIP, and strikeout rate are most important.
📊 Compare the implied probability
Earlier, we explained how contract prices reflect the market’s probability of an outcome. Sometimes, the collective opinion of traders may not be accurate, so the rates may misrepresent the actual likelihood of an event. If you compare the implied probabilities, you’ll know whether the prices are over- or underselling a team before trading.
⚡ Consider live trading
You can trade live contracts while a baseball game is ongoing. We recommend paying attention to the markets, as contract prices will move quickly based on real-time momentum. That way, you can spot and take advantage of favorable rates before the market adjusts.
💼 Trade responsibly
Our final tip is to always be on the safe side. You can do that by managing your bankroll and not putting too much money into a single prediction. Also, leave emotions out of trading and don’t buy event contracts just because you support a specific team or player.
