HOW KALSHI WORKS
Kalshi is the largest federally regulated prediction exchange where you buy and sell contracts based on event outcomes. Example: NASA announces a manned mission to the moon. Contract prices reflect trader probability estimates. If you think the event will happen, you buy contracts. Contracts cost between 1¢ and 99¢ and can be sold anytime. At market close, each correct contract is worth $1.
TRADE SPORTS

Kalshi lets you trade on real sports outcomes across football, baseball, basketball, golf, MMA, tennis, and more.
Will Baltimore beat Philly?
Will the total score go over 45?
Trade pro and college sports with highly liquid prediction markets. Experience live sports trading with unmatched market activity.
HOW IS KALSHI REGULATED?
Kalshi is federally regulated as a Designated Contract Market (DCM) by the Commodity Futures Trading Commission (CFTC). Kalshi’s affiliate, Kalshi Klear LLC, is a CFTC-regulated clearinghouse that holds member funds and clears trades.
TRADE YOUR CONVICTIONS
Find prediction markets that match your views. If you think a recession is coming, trade recession and S&P markets. Put your money behind your forecasts.
REDUCE FINANCIAL RISK
Hedge against events that could impact your finances. If you hold stocks, trade Fed and inflation markets to help protect your portfolio.
KALSHI VS. STOCKS
Event contracts are direct. You trade the outcome of an event, not the future stock price of a company. Profits are not tied to company performance. No pattern day trading restrictions. Trade as much or as little as you want, anytime. In stock trading, you can be right and still lose money due to market sentiment or news. Prediction markets remove that layer.
KALSHI VS. OPTIONS
Event contracts are simpler. Options pricing depends on multiple complex factors. Kalshi contracts reflect straightforward event probabilities. No time decay. If the event odds stay the same, contract value stays stable.
HOW MUCH MONEY DO I NEED TO START?
Open and maintain a Kalshi account for free. Prediction markets require less capital than traditional trading, making it easier to diversify without risking large amounts.

I had to put a 5 star review so it would be seen but the stars overall don’t reflect my review. The app overall seems great from an outstanding view but my issue is this… I’ve applied, meet the requirements, and reached out to support about my application. I have gotten multiple useless responses from the AI support system saying a team member will be with mewithin the hour, I receive no response after that, I also receive no message from a team member. I get responses in email but they tellme that I couldn’t be accepted, which I already knew. I would just like to receive information on why, how do I get accepted from this point on. My college baseball teammates do trade on this app and the trading overall is easily 4 to 5 stars. The support and help is below 1, it is unbelievable. Please let me receive some valuable help!

Great but never impoving

Kalshi hosts such a fun and legit market. It’s generally easy to use and absolutely worth a try. Unfortunately every update seems to make the app worse, mostly with awful UI choices that feel like they’re targeted at making users struggle more. Within the last month, you can fit significantly less information on your screen. Features such as the easy to understand profit that updates live such as simply saying 100->156 is now pushed onto a separate screen rather than on the live score page. This is the biggest downside recently, as it takes away a lot of confidence to place bets when you can’t see the live percentages, score, graph, and profits all on the same page anymore. In sports, the teams you’re betting on seem to be intentionally listed out of order at every chance they get. Jets @ Bears in the title and maybe on the scoreboard too, then the buttons to bet are listed as Bears first then Jets. These inconsistencies are everywhere. Some categories don’t get a lot of love. Tennis commonly has matches simply never appear. And the recent cherry on top to bad updates, is that the percentages are almost never accurate to each other on screen. The graph might show Jets 37% and Bears 63%, while the buttons show Jets 56% and Bears 56% commonly not equalling 100%.
Horrible support

Let me start by saying this app regularly freezes, crashes, shows incorrect values to your positions, etc.I had been using the app for a few weeks and just powered through these temporary inconveniences. This weekend was enough to give me reason to STAY AWAY. On Saturday I checked to see the lines on the following days games. The app showed me as having 0$ in my portfolio, which I knew was far from the case having won a considerable amount just days prior. By the end of day whatever technical issue Kalshi was experiencing sorted itself out and my balance was restored. Still unsettling.The following day I went to place money on a combo for NFL football. An error message occurred when I tried to submit stating that the odds had changed, it could not be submitted, and to try again. So I tried again. Same message. I did this multiple times. I eventually gave up trying to submit what was intended to be a SINGLE placement. When I ent back to my portfolio I saw that the combo had been placed MULTIPLE times (placing an absurd amount of money on a single unlikely event). When I contacted support giving them an explanation stating that this was placed on their own error message misinforming me, I was given a very brief response that no refunds are issued. No looking into THEIR MISTAKE. No accountability for THEIR ERROR. Nah, just you beat and out of all your money. And don’t put a support reply at the end of this review saying I should contact support because I tried that several times.Stay away from this app. These people are frauds.
Can you add badminton?

I’ve been really enjoying using Kelsey so far. The interface is clean, intuitive, and actually feels thoughtfully designed instead of rushed. Everything loads smoothly, navigation makes sense, and I didn’t have to “figure it out” — which is honestly rare for a lot of apps these days.What I appreciate most is that it feels like the developers actually care about user experience. The small details matter — the responsiveness, the organization, the overall simplicity. It’s not cluttered. It’s focused. And that makes me want to keep using it instead of abandoning it after a week.I do have one feature request though: could you please consider adding badminton as an option? 🏸 It’s such a popular sport globally — especially in Asia and increasingly in the U.S. as well. A lot of college students (including people like me) play recreationally or competitively, and it would be amazing to see it supported in the app. Adding badminton would open the door for a whole new group of users who are currently underserved.Badminton is fast, technical, and community-driven — it deserves representation just like other mainstream sports. Even a basic version to start would already make a big difference.Overall, I genuinely like the direction of this app. It feels modern, clean, and promising. With a few more additions like badminton, I think it could become something even bigger.
