Content is promotional and not a recommendation to trade. Contract pricing fluctuates and is subject to change.

Kalshi is federally regulated by the Commodity Futures Trading Commission, which is an independent government agency. The CFTC has regulated derivatives markets since the 1970s, and Kalshi is regulated as a Designated Contract Market (DCM). Because Kalshi is federally regulated as a DCM, it can be used all across the country. Some states, however, have moved to restrict Kalshi's usage and are currently in legal battles with the platform. As such, sports event trading is not available across all 50 states. 

Kalshi is not sports betting. Kalshi is a prediction market that allows for trading on different sporting events (in most states) and topics. You're trading contracts/shares, oftentimes buying them from other Kalshi users, similar to how the stock market works. Many contracts on Kalshi are of the "yes/no" variety and are based on percentages in the form of dollar amounts – $0.35 per share, for instance. A winning prediction pays out $1.00 per share.

Kalshi users trade prediction contracts for the outcome of specific events. Prices are listed in percentage form, and you choose whether you're buying "yes" or "no" shares. 

For example, if you were trying to trade on Los Angeles to defeat Denver, Los Angeles "Yes" to win may be priced at $0.40 per share. That means there's an implied probability of 40% for L.A. to win that game. If you were to buy 100 shares – $40 worth – of Los Angeles winning, the payout if you are correct would be $100 ($60 in profit). Whenever you purchase event contracts, you will get a review where Kalshi breaks down your investment – dollars and price point – as well as what the payout would be if your prediction is correct. 

It's important to note that there are two main ways to buy shares at Kalshi. With "quick order" purchases, you are immediately purchasing a specific number of contracts at the best available price. This means if you were trying to purchase $10 worth of contracts, you may wind up with $9.86 worth, given what's available at the current price point. With "limit orders," you specify the maximum price you're willing to pay per share. If shares are available at that price or even lower, your order will be executed. That means if the prediction you want to purchase contracts of is trading at $0.45 per share, and you don't want to spend more than $0.40 per share, you'd set your limit order at $0.40 and, if the number of shares you've specified becomes available at your listed price point, your order will go through. If not, you won't have an order placed on that specific market. 

The percentages and price points for different markets shift regularly, much like the stock market. Unlike sportsbooks, where oddsmakers are the ones changing and updating odds as different news and information come to light, Kalshi prices are dictated by the market. A high influx of share purchases or sales for either side of Yes or No can drive prices up or down. But once you purchase your shares at a certain price, you're locked into that price point. You can also choose to sell your shares before the market is graded out.

Whenever you go to buy shares through Kalshi, there will be a rules summary for the market that you have selected. This will explain the terms and conditions for what must occur for "Yes" or "No" to be the correct prediction for that market. Additionally, there is a "Timeline and Payout" tab that Kalshi users can select in order to see when that market first opened, when the market closes, and when the projected payout will occur. 

Kalshi determines market outcomes after it receives data from its source agency that verifies the outcome of each market. Additionally, Kalshi users can select "Request to Settle" when on the page for that specific market if they feel the terms and conditions for that particular market have been met. 

Trading on Kalshi is not sports betting, nor is it a sportsbook. Kalshi is federally regulated. Sportsbooks are licensed at the state level and aren't as available across the country. 

Sportsbooks also have odds for different games and events that are set and changed by oddsmakers. At sportsbooks, bettors are betting against "the house." 

Users can see Kalshi contract prices change for different sporting events, but those changes occur based on user buying activity and interest. More purchases or sales for one specific side of an outcome could drive contract prices up or down. 

Kalshi users also have the ability to place "limit orders." With a limit order, you set the maximum amount per share you're willing to spend, so that you can target an ideal price point should the market change in your favor. If "Yes" contracts are trading at $0.55 per share, and you don't want to spend more than $0.50 per share, you can set a limit order where, if that $0.50 price point becomes available, an order will automatically go through so long as the number of shares you want is also available. 

This option means that Kalshi users don't have to consistently monitor share prices for a specific market if they don't want to, as the order will go through automatically if the price and total share parameters are both available. 

A big part of Kalshi's appeal is not only widespread accessibility but also the wide variety of markets that the platform provides. In addition to sporting events across different sports and leagues, Kalshi also allows users to trade contracts for topics like:

There are short-term contracts that can be placed, such as the winner of a specific sporting event that day, or long-term contracts, such as the winner of the 2028 Presidential election or the nominee for each party. The "Culture" section of Kalshi offers various markets, such as movies that will win awards at shows like the Oscars, how many sales a specific album will have, the review score a new movie will receive, the winner of different reality TV shows and much more.

Trade contracts on sports, politics, pop culture and more with the Kalshi referral code bonus:

Something interesting Kalshi offers is that user feedback plays a large role in the markets that become available on the platform. Kalshi features an "Ideas" tab on its app and website where users can share different markets they'd like to see added to the platform. 

Per Kalshi, "We analyze all markets that are suggested to make sure that they are compliant with CFTC regulations, not easy to manipulate, and are in the interest of our users, so we cannot promise that every market suggested will make it to the platform." 

The "Ideas" section of the app is similar to a social media platform's feed, as you can "like" and comment on different posts and suggestions. You can also see the most popular posts for a given day, week or month. 

Kalshi also offers "The Orderbook," which displays all "resting orders," or buy/sell offers for a market that have yet to be matched with a trade. The Orderbook displays every resting order and its corresponding price. 

For example, there may be 4,000 contracts available to buy "Yes" for $0.70 each and 5,000 contracts available to sell on the "No" side for $0.75 each. That means someone is willing to bid as much as $0.70 per share for Yes shares while someone is selling their No shares for as low as $0.75 per share. This helps users see what the high- and low ends of that particular market look like at any given time, and Kalshi users can use this option to buy another user's event shares for their listed asking price. 

Kalshi offers a wide range of deposit methods for its users, as well as a few different ways to withdraw your funds. Here's a quick breakdown of how Kalshi users can move their money around, as well as how Kalshi users can actually accrue interest through the platform. 

Kalshi offers a flat 3.25% annual percentage yield (APY) where users can earn interest on cash and open positions. This allows Kalshi users to maximize their returns and earn additional funds while holding positions. It also incentivizes users to purchase positions that will take longer to settle and hold onto them for longer periods of time. 

Interest rate accrual is only available to Kalshi users who have balances of $250 or more. The net value of your portfolio is determined by your account's available funds as well as your portfolio value at the end of the day, based on last traded prices. Interest is paid monthly but is accrued daily, and interest is typically paid out within the first week of the following month. It can take up to 10 business days for interest to process.

It's hard to find much fault with how the Kalshi app operates from a user experience standpoint. The platform places trending topics and events front and center on the app and site, and also features pages for key topics like sports, politics, culture and climate. Here's a quick breakdown of the Kalshi user experience.

Get started at Kalshi and earn $55 in bonus trading funds:

The Kalshi home page defaults to its "Explore" tab, which offers a "For You" setting based on your interests, existing and prior trades, as well as different trending topics. At the top of the screen, you can shift between sports, politics, economy, culture, tech and science, climate, crypto, companies, financials and mentions. Clicking any of these options takes you to a new curated page with tons of different markets for that specific topic. The "Search" function helps navigate to exact markets in the blink of an eye, while also allowing users to implement Kalshi's social features by finding other traders by their usernames. 

Kalshi also provides users with a "Featured Trades" section that allows them to see an array of trades that other users are making. Another interesting feature is the app's "15-minute markets" section, which provides markets instantly available to trade that resolve within 15 minutes.

The user interface is very strong on both the Kalshi app and website. It's very easy to find a topic or market and then make trades. Once a user decides on a market to trade on, they can input the amount of money they want to trade. Kalshi's interface shows the potential winnings from the trade and allows users to send it through with the slide of a finger. 

Everything you need is available within one to two clicks from the Kalshi home page, be it finding a market to trade, checking out your portfolio, or visiting Kalshi's customer support or FAQ menus. 

Kalshi's design is clear and easily navigable from the moment a new user creates their account. Every section is clearly labeled, and switching between markets is simple, seamless, and intuitive.  The app delineates topics clearly while providing clear methods for moving from market to market. 

If I were to make one design suggestion, it'd be to have a more prominent place for how trading on Kalshi works without having to visit the FAQ or help center pages. A focused tab under the hamburger dropdown menu would be an ideal place for that and could really assist new users, especially those who have never used prediction markets or traded on the stock market. 

There are slight differences between the Kalshi app and the desktop site, but not a ton. I personally like using the desktop site more than the app just because there's so much information available, and it can look a bit tidier and less crowded than on a smartphone app. But in terms of functionality, getting where you need to go and trading contracts, there's not much of a difference from a user experience standpoint – it really just boils down to personal preference between your phone/tablet or computer. 

By selecting "Portfolio," you can view and track all of your current positions, which include breakdowns of the price you bought them at, what the current price/percentage is trading at for that position and also what your total payout would be if your prediction is correct. By clicking on your positions, you can get even more options, including the ability to buy more shares or cash out of your current prediction. The portfolio tab also allows you to check your current resting offers if you have any, your overall prediction history for closed positions and your watchlist. 

To get in contact with Kalshi customer support, click the three lines/hamburger menu at the top-left corner of the app and click "Kalshi Support." By clicking "Your support chats" under the "Kalshi Support" option, you can start a live conversation with someone from Kalshi's support team. There, you can also view your active chats. The "Kalshi Support" tab also has an option to visit Kalshi's FAQ page and help center, which includes a section for contacting customer support via the email address support@kalshi.com. 

Kalshi offers a very strong platform to its users, with its key strengths being the available markets as well as the ability to set limit orders to get shares and contracts at an ideal price. Kalshi pays out fast while still offering an incredibly wide range of markets for users to place predictions, and it has a great mix of short- and long-term market options across all sorts of different topics. 

I found the desktop version of Kalshi to be better when it came to customizing my feed and the markets and topics that are most relevant to me, especially with a "sports" option for "Customize your view." You can select topics on the app under "Your interests," but I found the desktop version to be a bit better and cleaner in that regard. 

One other area I think could improve is the order process. I'm someone who has experience trading stocks, so I am very familiar with limit orders and how to utilize them. I think that Kalshi does a good job of breaking down how to use the platform, but pushing the difference between quick orders and limit orders to new users would be helpful and avoid potential confusion when someone goes to trade their first contracts with the platform.

Finally, it is worth comparing the Kalshi promo to prediction market promos of other brands. The Polymarket promo code, for example, offers a $25 trading bonus following an initial $10 deposit.

How does Kalshi work?

At Kalshi, users purchase "yes/no" prediction contracts for the outcome of different events. Each event contract/share is priced with a figure under $1, such as $0.25 per share. This $0.25 price suggests a 25% likelihood of that outcome occurring. For instance, if you were looking at a sporting event where New York was $0.25 to beat Boston and you purchased $25 worth of shares and New York won, you'd get your $25 back as well as $75 in winnings for a total return of $100. The percentages and prices for each event are dictated by the market, meaning traders buying or selling contracts can push prices up or down on a regular basis. 

Does Kalshi have election odds? 

Yes, Kalshi takes predictions for local, national and international elections available on the platform. It also offers a wide range of different political prediction markets, such as nominees for different governmental positions, which party will have majority control in Congress after the 2026 midterm elections and much more.

Disclaimer: Event contracts trading involves a risk of substantial loss and is not suitable for all investors. Participation in prediction markets is subject to applicable eligibility requirements.  Participation may be restricted or prohibited in certain jurisdictions and participants are responsible for ensuring their participation complies with applicable laws and regulations in their jurisdiction.
