Over 40 states have legalized prediction markets in the US. These platforms are legally allowed to operate through regulation by the Commodity Futures Trading Commission (CFTC). They are especially popular in states that don’t feature legalized MLB online sports betting. With just over a month remaining in the 2026 MLB regular season, the exciting action of the MLB Playoffs is right around the corner. Traders are jumping on available MLB markets for the season, postseason, and more using the top market trading apps like Polymarket and Kalshi.

New users to prediction market apps can use our available offers and links on this page to claim promo code bonuses to trade on MLB markets. These offers include deposit bonuses, bonus credits, trade-and-get promos, and other offers that will spice up the MLB postseason all the way through the World Series.

Trading on MLB is no different than using NFL prediction markets or NBA prediction markets.

Prediction Markets Pairing Up With MLB Teams

MLB teams are quickly partnering up with the top prediction market apps in the US.

Recently, Kalshi announced it agreed to MLB brand partnerships with five different MLB teams. Those teams are the Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants. As part of the partnership, each ballpark for the team will feature Kalshi signage and provide on-site activation options for attendees, as well as special Kalshi offers.

This agreement between Kalshi and five MLB teams follows Polymarket and Novig each agreeing to MLB partnerships earlier in the year. Novig reached a deal with the New York Mets, while Polymarket struck a partnership deal with MLB as a league.

MLB Prediction Markets for Games This Week

The MLB is heating up with key division and Wild Card races as we get into the thick of September. One of the featured games on the day has the Milwaukee Brewers hosting the Chicago Cubs. The Brewers hold a commanding 9-game lead on the Cubs in the NL Central after taking the first two games of the series already. The Cubs hold the second NL Wild Card spot, trailing Philadelphia by 1/2 a game. A big interleague series continues when the Atlanta Braves host the Tampa Bay Rays. Tampa took the series opener on Tuesday, 7-1. Tampa leads the AL East by four games while Atlanta leads the NL East by four games. The Rays are also the No. 1 seed in the AL by four games, while Atlanta sits back in third in the NL, 4.5 games in back of the Brewers for the top seed.

How to Use MLB Prediction Markets

Using an MLB prediction market is quite simple. Instead of traditional sports betting where you make a wager, prediction markets have you trade (buy/sell) contracts. These contracts are for yes or no outcomes to MLB events. Each contract has a “yes” or “no” option that carries a price based on the market probability of the outcome. Prices will be anywhere from $0.01 to $0.99. Users purchase the contract they want, then enter the amount they want to spend on their contract. The “odds” are determined by the market probability.

In the example provided, the Milwaukee Brewers are listed with a 13% chance to win the Pro Baseball Championship (World Series). Because the market lists it as a 13% chance, a $10 contract would pay out $75.36 if Milwaukee wins the World Series. Choosing “No” would pay significantly less.

If you need it spelled out, the equating is: Full contract price ($1) – Milwaukee Brewers price ($0.13) = 87/13 odds (+669)

World Series Prediction Markets

Will the New York Yankees win the 2026 World Series?
Yes 10% · No 91%
View full market & trade on Polymarket

The MLB World Series winner is among the top baseball markets available at prediction markets. Millions of dollars are being traded among the top MLB prediction market operators. Currently, the Los Angeles Dodgers remain the comfortable favorite in terms of probability. With baseball’s unpredictability come the playoffs; World Series markets are a great opportunity for using a limit order to set the prices you like for a given team. You also have the option to trade in these contracts early if a team gets hot or cold before the postseason arrives.

MLB MVP Prediction Markets

Will Yordan Alvarez win the 2026 American League MVP Award?
Yes 92% · No 8%
View full market & trade on Polymarket

The MVP race for baseball is always a hot topic, but this year the winners have started to create a little distance. Chicago’s Pete Crow-Armstrong is the clear leader in the NL over Los Angeles’ Shohei Ohtani, while Yordan Alvarez of the Houston Astros looks to be the runaway winner in the AL. While the markets now are pretty established, MVP markets during the offseason provide a lot more options that you can capitalize on.

MLB Cy Young Prediction Markets

Will Jacob Misiorowski win the 2026 NL Cy Young Award?
Yes 89% · No 11%
View full market & trade on Polymarket

Similar to the MVP races, the Cy Young races in the NL and AL are always a popular market for MLB traders. This year’s race has a similar look to the MVP races, as in the AL, New York’s Cam Schlittler has a comfortable edge on Dylan Cease of the Toronto Blue Jays. In the NL, Milwaukee’s Jacob Misiorowski is running away with the market, with Chris Sale of the Atlanta Braves a distant second.

Things to Remember When Using MLB Prediction Markets

If you want to give a shot at using baseball prediction markets, there are a few things to keep in mind.

Do your MLB research: The more you know about a particular matchup, or key trends in baseball, the better suited you will be to make quick decisions at the right time to capitalize on your contracts.
Study the markets: Just like if you were comparing odds at online sportsbooks, find the right market probability for the contract you want. Some prediction market apps allow you to set your prices for purchases and sales, so take advantage of the live trading aspects to get the most bang for your buck.
Start small: Don’t go overboard and dive in headfirst with an outrageous number of contract purchases. Find the right market for you and make a small first purchase to see how the process works. As you have a better understanding of the moving and shaking of the markets, you can further explore different sizes of trades.
