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.

18+ only. Restrictions and eligibility requirements apply. Trading event contracts and trading leveraged products, including perpetual futures, involves significant risk and is not appropriate for everyone. Please carefully consider if it is appropriate for you in light of your personal financial circumstances. Kalshi products are not available in all jurisdictions. See kalshi.com/regulatory for more information.
Additional perpetual contract offerings are subject to applicable regulatory review and approval, and availability may vary.
Leverage amplifies both potential gains and potential losses, and losses can exceed the amount deposited. Leverage limits are determined by KalshiEX LLC or the FCM based on its own risk assessment and each customer's individual risk profile, and are subject to change.
The only reason platforms like Kalshi are able to operate is based on the fundamental assumption of user trust. However, once that trust is abused, a company loses all credibility—and Kalshi has officially hit that wall for me.I went into this expecting a regulated, fair exchange, but the experience has been nothing short of a nightmare. From my perspective, they are not a company to be trusted. Whether it’s the way they handle trades or the lack of clear communication, the whole operation feels more like a scam than a legitimate financial platform.If you value your hard-earned money and your peace of mind, stay far away. There are much more reliable ways to manage your finances in this city—for example, I’ve found that even high-stakes luxury businesses like La Bijouterie understand the value of a client's trust better than this place ever will.Bottom line: Don't let the "regulated" labels fool you. If a company doesn't respect its users, it doesn't deserve to exist. Avoid at all costs.
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%.
Fishy sometimes

At first it was great app ran smooth, nothing ever lagged was easy to make money. Then after like 20k in profits, my phone started to overheat anytime I would open Kalshi, I would literally have to delete the app sometimes and re download it in the middle of a game because it would just Brick my phone. I thought maybe just coincidence, then it started to happen that when I was up on a bet, and wanted to get out it would just tell me that the odds had changed and to re submit my order over and over, and then sit there “processing” when I would submit an order to exit a bet when I was up a little bit thinking the game was about to flip. Too many coincidences to not feel like at this point it’s almost forcing me to lose on bets by not letting me exit by cashing out. And next thing you know I’m losing money and oh now it will let my order to cash out go through! Haha what?!? So I can’t cash out when I’m up but suddenly goes through when I’m at a loss without any lags or “odds have changed resubmit your order” I get it Kalshi needs to make money I guess and when they can’t have everyone winning. But it makes me not want to bet now so where you had someone like me every day betting and transferring money in and out, paying fees to deposit money, fees on each bet entry and exit, now I’d rather not. I can’t even leave the app downloaded on my phone because it drains the battery so much running in background
Developer Response
Kalshi is an exchange — orders match against other traders, and we don't take the other side of any position. If the market price moves before an order fills, the app asks you to re-submit at the new price. For the performance and order issues you describe, please email support@kalshi.com so we can review your account activity.
Horrible support
GodsNotRealBro
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.
