How Kalshi works for the 2026 MLB playoffs

Kalshi is a peer-to-peer trading platform where users buy and sell contracts on the outcome of games and other events. It differs from sports betting because you trade with other users, instead of betting “against the house.”

Kalshi contracts always cost $0.99 or less and pay out $1 if the prediction is correct. The price corresponds directly to probability, so a contract that costs $0.55 means the market thinks that prediction has a 55% chance of happening.

Here is an example of how the pricing works using the current prices for the Red Sox vs. Yankees game:

Buying a contract predicting the Yankees to win costs $0.56, so you need to buy 45 contracts to satisfy the $25 trade required to claim the Kalshi promo code. That order would cost $25.59, including a $0.39 transaction fee, so you would receive $45 and profit $19.41 if the Yankees win.

Do not be deterred by Kalshi charging transaction fees. That is how it makes money, since it does not profit when you get a prediction wrong (the user on the other side of the trade does). The fees are comparable in cost to the vigorish (vig) at sportsbooks, but a big advantage at Kalshi is that you can get lower fees (or no fees) on some orders.

Remember that Kalshi contracts are traded in a live market, so prices can change at any time. The chart below shows the real-time prices for Red Sox vs. Yankees and Cubs vs. Padres.

There are multiple Kalshi promo codes you can use to claim the sign-up bonus.

More prediction market bonuses: Polymarket US and ProphetX

You can claim trading bonuses at multiple prediction market platforms. Two of the most popular alternatives to Kalshi are Polymarket US and ProphetX.

Polymarket US offers new users a guaranteed $50 trading credit when they sign up with Polymarket promo code NJCOM and deposit $10. What’s nice about Polymarket US is that you receive the credit after making a deposit, not after making a minimum trade like at Kalshi.

ProphetX provides a $75 incentive to new users who sign up with ProphetX promo code NJCOM and trade $50 within 30 days. The $75 bonus is delivered in three $25 increments. Check the terms for details on how it works.

Why the Kalshi referral code NJCOM is the best option for trading on the 2026 MLB playoffs

Kalshi offers several advantages compared to online sportsbooks. Here are a few of the biggest differences that offer compelling reasons to give Kalshi a try:

1. You can trade in states where you can’t bet: Since Kalshi isn’t a sportsbook, it is not restricted by state gambling laws. It is federally regulated as a financial exchange by the Commodity Futures Trading Commission (CFTC), which means it’s available in several states where sports betting is not, such as Alabama, California and Texas.
2. You can offer different prices: You have the flexibility to offer prices below the market average and try to find another user to trade at that price. At sportsbooks, the only option is betting at the current odds.
3. You can sell contracts anytime: Selling contracts on Kalshi is similar to cashing out bets early at sportsbooks. However, you can only cash out certain bets at certain times. On Kalshi, you can sell any open contracts at any time for the current market price.
4. Earn interest on your entire portfolio: Kalshi pays interest (currently 3.25%) on your open contracts and unused cash if you have at least $250 in your account. Sportsbooks do not pay any interest for the cash you keep in your betting account.
5. Trade on anything: You can trade predictions in other categories besides sports, like elections, politics and pop culture. One of the popular non-sports markets trending on Kalshi this week is “How many album sales will Taylor Swift’s new album have during its first week?”

Note: Event contract trading involves risk of substantial loss and is not suitable for all investors. Prediction market content is not intended for individuals located in jurisdictions where they are prohibited.
