Follow these directions to set up your new Kalshi account:

Kalshi is not another route to sports betting. The platform operates differently than a sportsbook.

You do not place bets or see fixed odds like you do at a traditional sportsbook. Kalshi customers trade on a peer-to-peer, federally regulated platform that crowdsources its implied probabilities and prices.

Trading on Kalshi requires participants to buy event contracts that are based on ‘Yes’ and ‘No’ sporting outcomes.

Contracts cost $0.01 to $0.99. All winning contracts pay out $1. Your profit is $1 minus the contract price.

Here is how Kalshi works for an MLB playoff game:

For today’s Braves vs. Phillies game, the market for over 6.5 total runs scored is priced at $0.53. The price continuously moves based on user trading activity.

If the Braves win 4-3, the over will hit. The winning contracts on that outcome will pay out $1 each, with a resulting profit of $0.47.

Starting pitcher Chris Sale will take the mound for the Braves, and he will be opposed by fellow left-hander Jesus Luzardo.

Later on Tuesday, the most storied rivalry in sports opens a new chapter when Yankees SP Cam Schlittler matches up against Boston’s Peyton Tolle.

Kalshi is now accessible in more than 40 states, including some where sports betting is not allowed. Here are some alternate Kalshi referral codes that can also unlock welcome offers:

You’ve placed your trade, your team is about to win and you want your cash. How fast can you do that with Kalshi?

Depending on the method you choose, Kalshi withdrawal time is quite fast.

Many Kalshi markets pay winners within minutes of market settlement. For MLB Playoff games, Kalshi lists a settlement time of two minutes. Once the funds are in your account, you can withdraw.

Venmo is Kalshi’s fastest withdrawal method. Payouts are distributed in less than 30 minutes using the instant withdrawal method, though it comes with a 1.75% fee (minimum 25 cents). You must have deposited with Venmo for the instant withdrawal to work.

Use a standard Venmo transfer to avoid the fee. This method takes 1-3 business days.

Debit cards, including those linked to Google Pay and Apple Pay, also have free transfers. This method takes up to 30 minutes. If you’re not in a rush to get your money, you can use a bank transfer, which takes 3-5 business days.

Using tonight’s Cubs vs. Padres game as an example, here is how Kalshi displays the market settlement time on its market pages.
