Top MLB Prediction Market Sites to Explore
Best MLB prediction market sites
We’ve reviewed the top prediction markets based on factors like market depth, liquidity, fee structures, and overall usability. Kalshi, Crypto.com, and Polymarket stand out as the best options for MLB event trading. Below, we take a closer look at what sets each brand apart.
Kalshi - Best MLB prediction market overall
Kalshi is the best MLB prediction market site overall thanks to its strong market coverage, deep liquidity, low fees, and polished mobile app. It offers an extensive selection of MLB markets, covering everything from daily game outcomes to long-term season futures. You’ll find moneylines, run lines, totals, team totals, season win totals, division winners, league champions, World Series winners, and more.
Where Kalshi really stands out is with its player prop selection. You can trade on a range of individual player performances, including home runs, hits, strikeouts, RBIs, stolen bases, outs recorded - you name it.
Another standout feature is Combos, which lets you combine multiple eligible MLB markets, including game outcomes, totals, and player props, into a single tradable contract using the combo builder tool.
Crypto.com - Best up-and-coming MLB prediction market
Crypto.com launched its prediction market in late 2024 and has grown rapidly ever since. In early 2026, the company reported that weekly trading volume had increased 40x over the previous six months, largely driven by strong adoption of its sports event contracts.
Its sports event contracts cover a wide range of MLB markets, including game winners, run lines, totals, player props, and season futures such as division winners, league champions, and World Series winners.
Crypto.com also stands out with its Combos feature, which lets you combine up to six pre-game or live MLB picks, including game winners, run lines, totals, and player props, into a single position with the potential for higher payouts. Eligible combo positions can be closed early, allowing you to lock in profits or limit losses before all of your contracts have settled.

Polymarket - Best MLB prediction market for liquidity
Polymarket is the world’s largest prediction market by trading volume, providing consistently high liquidity for MLB event contracts. Markets cover individual game outcomes, season-long awards, championship futures, and a wide range of props. The prop selection is particularly impressive, including team and player props as well as markets on league events, rule changes, roster moves, and injury-related developments.
Like Kalshi and Crypto.com, Polymarket also offers Combos for MLB markets, including moneylines, run lines, and totals, allowing you to bundle multiple picks into a single position. Like standard positions, Combo positions can be sold before settlement, allowing you to secure profits early if market prices move in your favor.
How MLB prediction markets work
MLB prediction markets let you trade contracts based on the outcomes of real MLB events, including individual games, player performances, season awards, and championship winners. As is the case at the best NBA prediction market sites, each contract is typically based on a simple Yes/No question.
For example, “Will the Philadelphia Phillies beat the Boston Red Sox?” or “Will Kyle Schwarber hit a home run?” If you think an outcome will happen, you can buy “Yes” contracts. If you think it won’t, you can buy “No” contracts. Simple as that.
Contract prices and payouts
Contract prices typically range from $0.01 to $0.99 and reflect the market’s implied probability that an outcome will occur. Prices fluctuate based on overall market activity, and you can sell your contracts before the market closes to lock in a profit or limit your losses. If you hold your contracts until settlement, each winning contract settles for $1, while losing contracts expire worthless.
Pros and cons of MLB prediction markets
Like the best tennis prediction market sites, MLB prediction markets come with both advantages and disadvantages. Here are the main ones to consider:
- Regulated by the CFTC
- Sell contracts before settlement
- Low minimum contract prices
- Wide range of MLB markets
- Liquidity varies across markets
- Availability may vary by state
Is MLB event trading the same as sports betting?
MLB event trading is often confused with sports betting, and it’s easy to see why. Both involve predicting the outcome of MLB events, and both can offer a real money payout if your prediction is correct.
However, MLB event trading is different from sports betting. At a sportsbook, you place bets against the bookmaker at the odds it sets. In contrast, an MLB prediction market is a peer-to-peer exchange where users buy and sell event contracts with one another.
Contract prices are determined by market supply and demand, rather than being set by a sportsbook. The table below breaks down the key differences between MLB event trading and sports betting in more detail:
| Feature | MLB event trading | Sports betting |
| Regulation | Federally regulated by the Commodity Futures Trading Commission (CFTC) as event contracts | Regulated by individual state gaming regulators |
| Availability | Available in most US states | Only available in states where online sports betting is legal |
| Minimum age | Typically 18+ | Typically 21+ |
| How it works | Buy and sell event contracts based on MLB outcomes | Place fixed-odds bets with a sportsbook |
| Counterparty | Other traders on a peer-to-peer exchange | The sportsbook |
| Pricing | Buy and sell event contracts tied to MLB outcomes | Odds are set by the sportsbook |
| Payouts | Winning contracts typically settle for $1 each | Payouts are based on the odds when the bet is placed |
| Early exit | Positions can be sold before settlement to lock in profits or reduce losses | Cash out may be available |
| Market types | Moneylines, run lines, totals, props, and more | Moneylines, run lines, totals, props, and more |
Are MLB prediction markets legal in the US?
Yes. MLB prediction markets are legal in the United States at the federal level. They operate under the oversight of the Commodity Futures Trading Commission (CFTC), which regulates the event contracts they offer as financial derivatives.
As a result, they’re available in most US states, including many where online sports betting is not legal. That said, some states have filed lawsuits or taken enforcement actions, arguing that the sports-based event contracts violate state gambling laws. Because of these ongoing legal disputes, availability may change over time, and access could be restricted in certain states.
You’re ready to trade MLB event contracts
Baseball is America’s favorite pastime, and the best MLB prediction market sites let you put your knowledge to the test by trading on everything from individual games and player performances to season-long futures and World Series champions.
If you’re new to sports prediction markets, trading MLB event contracts might seem intimidating at first, but it’s surprisingly simple. Most markets revolve around a straightforward yes-or-no question. Just buy the Yes or No contract based on what you think will happen, then sit back and see how it plays out.
If the market moves in your favor, you can sell your contracts before settlement to lock in profits or limit potential losses. Alternatively, if you're confident in your prediction, you can hold your position until settlement, when each winning contract typically settles at $1.
