How does Kalshi work? A clear breakdown of cash prediction markets for 2026

Kalshi is often considered the leading P2P prediction exchange and it boasts some of the largest trade volume and liquidity for the immense range of prediction markets that it offers on real-world events.

But, how does Kalshi work? If you’ve been looking at starting here, we’ve created a complete introductory guide below. Read on as we explain how the peer-2-peer trading setup works at Kalshi, and what you can do with the trade contracts you buy. We’ll also discuss examples of the types of predictions you can trade here.

How does Kalshi work? A detailed introduction

Kalshi is a peer-2-peer prediction exchange where customers from around the world can buy and sell trade contracts relating to real-world predictions. These predictions cover a multitude of different events including national elections, the price of crypto, sports events, and the price of commodities.

Trade contracts at Kalshi

Trade contracts are the underlying foundation of Kalshi. Each prediction they have will also have a series of trade contracts. For example:

“Will the US confirm that aliens exist before 2027?”

• Yes - 8.6c.
• No - 91.8c.

This is an example of an actual prediction at Kalshi and you have three main components - the prediction itself, and a yes and no option with a relevant price. The yes and no options are the trade contracts and these are what you can trade with other people. There’s nothing like Kalshi odds - the trade contract price simply changes based on trader sentiment and the implied probability of the event happening or not.

So, in this example, you would be able to buy “No” trade contracts for $0.918 each. Because the default value of a trade contract is $1, we can see here that the “no” option is being touted as the likely outcome, and it essentially has an implied probability of 91.80%. Please remember though that implied probability is not a guarantee - the public can get predictions wrong.

Buying and selling trade contracts

When you’ve signed up to Kalshi using our banners, you have the option of buying trade contracts for predictions. If the trade contract price then shifts in your favor, you could also consider selling them to try and make a return. You must be aware of the Kalshi trading fees though, as buying and selling typically has an associated fee for each action which can reduce your potential profit.

Settling trade contracts

Alternatively, you also have the option of trying to settle your trade contracts. This means you buy some trade contracts for a prediction, and then hold them until the event happens. At this point, one of two things can occur:

• You settle in-the-money: if this happens, you got the prediction right, and you’ll get a $1 return for each settled trade contract.
• You settle out-of-the-money: in this instance, you got the prediction wrong and when this happens you get a $0 return on your trade contracts.

Pros and cons of Kalshi

We rate Kalshi as one of the top prediction exchanges. It has the benefit of having one of the largest customer bases, and thus offers superb trade volume and liquidity for most of its markets. Additionally, it has a huge selection of prediction markets, covering everything from sports and science to politics and crypto.

From a usability perspective the site and mobile apps work great too, and it also has a variable trading fee structure that isn’t too detrimental to your overall returns. The only real area where Kalshi falls short a little is its lack of promotions or bonuses for both new and existing customers.

How to create a Kalshi account

If you want to give Kalshi a try, you need to register an account. Now, you should be able to browse the prediction markets and look at the site’s features without an account, but things like depositing and trading, you’ll need to complete the following steps:

1. Click our Kalshi banners.

2. Click the sign up button.

3. Choose your sign up method (Email, Google, or Apple).

4. Enter the relevant details.

5. Do any initial verification.

6. Log in to your new account.

7. Complete the full KYC check.

From our experience, Kalshi is pretty with its KYC and signup processes, and at some point depending on your location, you will need to do a full ID verification process. This involves uploading a copy of a photo ID such as your passport, entering your address and other info, and uploading a live selfie so that your likeness can be verified.

This process is unavoidable if you want to unlock everything this P2P prediction exchange offers.

Kalshi in the US

Is Kalshi legal in the US? Yes, and in terms of functionality and features, there is no discernable difference between the US version and global version. US customers should still have access to the same prediction markets, promotional features, and trading tools. You should also be able to use both the desktop website and the downloadable mobile apps.

In terms of US accessibility, Kalshi currently operates in 45 states, but this can change without notice due to the changing landscape of prediction exchange regulations. The best thing you can do as a US customer is check out the banners we have on this page.
