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.
Trade pro and college sports with highly liquid prediction markets.
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.

Pros: Love the app. Finally something different from traditional sports betting. The best part is anyone can win hundreds or even thousands of dollars with $10 or less. If you get really good you can make a legit living off just this app and make more than enough to pay your bills and quit your job. ( I don’t recommend doing that, but some people are just that good and make millions.) You can bet on ANYTHING, not just sports. So if you’re good with politics or economics, even the weather, you can make money. Cons: Very addicting, you can lose money fast, sometimes it feels like they rig certain bets although it’s highly illegal so they most likely don’t, but when you lose a bet that has an 80% win rate, it can definitely feel that way. The new interface after the update…I hate both the way the app looks and feels, the old one was so much easier to understand, and navigate. I got used to the old one already, then they change everything around, and from the people I know that use the app, I’m not the only one that thinks that, many feel the same way. Please go back to the way the app was before this update ! 🙏🏻If you got a few bucks to spare, and wanna try to win some money I highly recommend this app. If your addicted to gambling, stay FAR, FAR AWAY! Anyways, this is my new favorite app to make money for like a side hustle where I can make legit money and a significant amount, not just a couple bucks here and there, just go back to the old layout and interface, PLEAASSEEE!!!

Thanks for the feedback! For the connectivity issue, you might want to reach out to your phone carrier to see if there might be a reason this is happening, as it's most likely not something on Kalshi's end.Great to hear you're enjoying the app overall!Thanks for using Kalshi!
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.
Too many glitches and bull

Go to Polymarket and stay as far away as you can from Kalshi, at least for crypto trading. In all my years of trading, this is the scammers market for trading. Every single time I try to buy in at a lower percentage, Kalshi will tell me the price has changed. Until I finally buy in, now I’m at 38% instead of 15%. Simply because market flow changed. That doesn’t matter, as a platform that handles trading. You should be able to accept my offer at that exact time. HOWEVER, if you purchase at 38%, but then market moves and it drops to 15%, Kalshi will GLADY accept your trade, leaving you in the negatives and paying you off of 38%, instead of saying “The Price Has Changed” and stopping you from basically robbing yourself. Also, IF, you successfully manage to get in at 5% and it does go higher, like 42%, the very moment you try to cash out, Kalshi won’t let you and will tell you the market has changed. THAT SHOULDNT MATTER, considering this is one of the top prediction markets available. You should honor I was trying to cash out. I cannot control the market changed .2 seconds as I was sliding the cash out function.I have lost money in FAIR trades, and I have lost ALOT more due to Kalshis bullcrap. Kalshi makes it as impossible as possible to make money, that’s probably why 95% of their users are in debt and not profiting. Stay away from Kalshi, go to Polymarket.
