Kalshi offers event contracts on the NFL, NBA, international sports like soccer, and even esports. However, sports markets at Kalshi are controversial and restricted in several states.

Is Kalshi legit? My verdict
Yes. Kalshi runs as a federally regulated exchange, not an offshore operation, and that shows up in how it handled my money throughout testing.
I came away with a 4.2 out of 5 overall, one of the stronger marks among the prediction market sites I've put through the same testing process, carried mostly by sheer market depth and a surprisingly complete set of trader-protection tools.
How We Test Every Review
Every prediction market review follows the same 6‑category testing process, with real money and real trades.
Market Coverage
Count live markets by category
Promotions
Claim and verify the welcome offer
Banking
Time deposits and withdrawals
Customer Support
Live chat and email
Liquidity
Real $10 trades on busy and quiet markets
UX & Responsible Trading
Test the app and trading limits
Every review runs on a $20 real-money budget, and testing spans multiple days to confirm we can exit every position.
The catch is where I actually lost time and money. A live chat conversation dragged on for hours before anyone resembling a real person answered, twice over, and a quiet market I'd parked money in for a day or two got noticeably more expensive to exit than I expected going in.
Neither is disqualifying, but both are worth knowing before you fund an account.
Testing evidence from Kalshi Predictions
Promotions: I signed up, claimed the welcome credit myself, and traded the required amount to see whether it actually paid out as advertised.
Market Coverage: I worked through every category one by one, then drilled into Sports league by league to see where the real depth actually sits.
Banking: I sent real withdrawals and clocked exactly how long a resolved market took to turn into spendable cash.
Liquidity: I put $10 into a crowded market and $10 into a sleepy one, then tracked the real cost of getting back out of both.
Customer Support: I asked live chat and email the same handful of direct questions more than once, to see if the answers held up.
User Experience & Responsible Trading: Rather than trust Kalshi’s claims, I clicked through each safety feature on my own account to confirm it actually worked.

Kalshi promo code and sign-up bonus: 3.2/5
I signed up, applied the promo code, and traded $25 inside the window Kalshi allows, and the matching $25 landed as bonus credit exactly as described.
It’s a clean, no-surprises 1:1 match, with no deposit minimum sitting in front of it. I just can’t spend it on Perps, Kalshi’s separate futures product — Predictions markets only — and I had a week to use the credit once it posted.
Beyond the welcome offer, the only other promotion I found is a referral program: bring in a friend who trades $25 of their own, and the payout can reach $2,000 depending on the invite. There’s no cost to me as the referrer beyond actually getting someone to sign up.
Compared with some of the richer welcome packages I’ve tested on platforms like Polymarket or Underdog Predict, Kalshi’s own match is on the smaller side, which is really the only thing keeping this score down.
Why I rated Kalshi 3.2/5 for Promotions
Nothing hidden in the fine print and an unlimited referral upside, but a $25 ceiling that doesn’t stretch as far as some rivals I’ve tested.
What you can trade on at Kalshi: market coverage, 4.7/5
I counted live markets in all eight categories I track, plus a small novelty bucket, adding up to more than 5,100 contracts at the time of testing. Sports alone contributed well over 4,350 of those, and soccer, the NFL, college football and esports each had the trading volume to back it up, not a thin listing standing in for a whole league.
Inside Sports, I only credit a league with genuine coverage once it clears 5 live markets. Six leagues didn't clear that bar at all — nothing live in horse racing, rugby's Australian code, handball, poker or pickleball — which left 21 of the 27 I track with a passing grade.
Across a 16-market sample spanning every category, I specifically looked for whether each one spells out a real, independent source for its own resolution. Fourteen passed that bar outright, and only two left Kalshi any wiggle room to decide the outcome itself.
Nothing I tested on competing platforms, Crypto.com included, had an equivalent to Kalshi's Mentions category, where the entire premise of a market is whether someone utters a particular word during a live speech or public appearance. When a real story broke mid-testing, a tradeable market on it went live within 10 hours.
Sports
Politics
Politics is one of the most vibrant categories, with markets covering events like election outcomes, the passage of bills, congressional votes, new appointments, and more.
Economics & finance
Markets under the economics and finance categories cover topics like interest rate decisions, GDP growth, stock index levels, cryptocurrency prices, job numbers, and more.
Science & technology
There are lots of interesting events to trade on in the science and tech categories, such as when the next iPhone model will launch or who will win the AI race.
Entertainment
There’s no shortage of events to trade on in the entertainment categories, such as the Oscars and Grammys awards, reality TV, movie box office performance, and more.
Weather & climate
Markets are based on different weather seasons and overall climate trends, such as temperature records, snowfall totals, and more.
Kalshi banking, fees and withdrawal speed: 4.8/5
Funding options weren't a limitation here. On top of the standard bank-transfer and card routes, Kalshi let me fund through several mobile wallets or move larger sums by wire or crypto, and $10 covered the minimum on nearly everything. I tested Venmo withdrawals directly, and each one cleared in minutes at no cost.
I also clocked a real market settlement, and the payout showed up as spendable balance only 9 minutes after the event itself wrapped up.
There's a real cost to every trade, too: Kalshi's fee runs about 7%, scaled by how close the contract's price sits to the midpoint, so a near-sure thing costs pennies while a genuine 50/50 contract costs the most. A 50-cent contract, for example, ran me about 2 cents in fees, shown plainly on the desktop order ticket before I confirmed. I never found that same number on mobile before committing to a trade.
One real perk: idle cash earns 3.5% interest here, and that rate follows money even while it's tied up behind an open position, something I haven't found on every competing platform. My one hiccup in testing was a mobile crypto deposit that threw a vague error message; switching to desktop revealed the actual cause, a missing SSN on file.
Why I rated Kalshi 4.8/5 for Banking
Fast withdrawals, clear fee math and real interest on cash sitting idle, losing only a little credit to one mobile glitch and a fee disclosure gap on the app.
How liquid are Kalshi's markets? 3.5/5
Kalshi runs on a genuine bid/ask order book rather than a quoted price, meaning you're watching real buy and sell offers from other traders, not a single number the platform hands you.
To see this play out firsthand, I put $10 into each of two very different markets: a heavily-traded Texas Senate race, and a slow-moving one asking whether a video game would launch before 2028.
Exiting the Senate position that same day cost me 6.60% round-trip, with my fill landing exactly where the quote said it would. The quiet one told a different story once I let it sit: coming back a day or two later to exit, the order book had thinned out and the gap between bid and ask had widened, pushing my real cost closer to 19%, nearly three times what the busy market charged me.
Behind the scenes, Kalshi pays outside firms to keep that gap from widening too much, through a Market Maker Program on one hand and a distinct Liquidity Incentive Program on the other.
Why I rated Kalshi 3.5/5 for Liquidity
A clean, no-slippage fill on a busy market, undercut by a quiet one that got meaningfully pricier to exit after only a short wait.
Kalshi customer support: 3.7/5
Only two official ways to reach support exist, live chat (app or web) and email, with no phone line or text option at all. Kalshi claims both run 24/7.
I tested live chat on two separate occasions, and both times, getting an actual person on the line took hours, roughly nine the first time and six the second. Even once someone did join, the tone barely shifted from the bot that handled things beforehand.
Email looked better at first glance — a bot answered in two minutes flat — and an actual Operations staffer followed up 63 minutes after that with a real response. I put five direct questions to support, and two came back as an unhelpful "no documentation on that" response rather than a real answer.
Kalshi does maintain a formal disputes process separate from everyday support, giving traders two years to file a claim with a fee that scales to how much is in dispute. The self-serve Help Center is genuinely strong, though — a searchable library detailed enough that I rarely needed to reach out at all.
Why I rated Kalshi 3.7/5 for Customer Support
The Help Center alone nearly carries this score, since the live channels left me waiting hours and gave me two wrong answers out of five tries.
Kalshi app and responsible trading tools: 5.0/5
Kalshi's apps are well-reviewed on both platforms: 4.8 stars across more than 528,000 App Store ratings, 4.7 from upward of 109,000 Google Play reviews with a million-plus downloads behind it.
I noticed desktop gives you a few extra sorting and filtering options mobile doesn't, though day-to-day, the two feel like the same product. I hit exactly one snag the entire testing window, a crypto-funding error on mobile that desktop later explained.
I went down my full seven-item checklist and confirmed each tool actually functions rather than just appearing on a settings menu: limits on deposits, limits on losses, a reminder based on session length, a cooling-off option, self-exclusion, a link to crisis-line resources, and age verification at sign-up.
Two things go beyond what I'd consider the bare minimum: Health Check, which monitors how you trade and may recommend a deposit cap tailored to you, and Inner Circle, an opt-in feature that shares your activity with someone you name.
Why I rated Kalshi 5.0/5 for User Experience & Responsible Trading
A stable, well-built app paired with a genuinely complete safety toolkit and real extras most competitors skip — I couldn’t find much to dock here.
Is Kalshi safe and legal?
The corporate structure here has three distinct pieces. The licensed exchange itself goes by KalshiEX, LLC, a status the federal government conferred back in November 2020. Kalshi Klear LLC clears trades and holds collateral under its own separate registration. And Kalshi Inc., the parent company, holds neither license directly.
Your actual cash never sits with Kalshi the company — Klear routes it into accounts kept separate from Kalshi's own books, presently parked at a First Citizens Bank subsidiary, Silicon Valley Bank.
I'd stop short of calling it fully insured, though: an FDIC-eligible sweep program exists, but Kalshi won't promise it covers any one trader, and SIPC coverage doesn't apply here at all. On the legal side, Kalshi's authority to list disputed contract types has already been litigated more than once, and it's won each time so far.
State availability is broader than most platforms I've tested — see the States Map above for the full, current list.
Comparing Kalshi With Other Prediction Platforms
PredictIt
PredictIt focuses exclusively on political forecasting through a simple share-based model. Kalshi covers a broader range of markets including economics, sports, and global events, with a more modern interface.
NinjaTrader
NinjaTrader offers deep futures market exposure for experienced traders but comes with a steep learning curve. Kalshi is more accessible, with simple yes/no contracts and an interface designed for everyday users.
Interactive Brokers
Interactive Brokers embeds prediction contracts into a full brokerage environment. Kalshi is a standalone prediction site that’s easier to navigate, though it lacks IB’s broader financial trading integration.
Final verdict: Is Kalshi worth it?
Kalshi earns its 4.2 out of 5 by covering more ground than almost anything else I've tested, eight full categories, real interest on idle money, and a trader-protection toolkit that's actually complete rather than just advertised. If you want breadth beyond sports and like seeing a real order book before you commit, this is a strong option.
Where I'd pump the brakes: don't expect a fast human on the other end of live chat, and think twice before parking money in a thin market for more than a day or two — the cost to get back out can climb fast. Neither issue erased my overall confidence in the platform, but if you'd rather pair predictions with more traditional investing, Moomoo is worth a look too.

Frequently Asked Questions (FAQs)
Not exactly. Kalshi sells event contracts tied to sports outcomes, which settle like a financial instrument rather than the fixed-odds wager you’d place at an online sportsbook, and sports contracts specifically are restricted in a handful of states.
Yes. I verified this directly against the CFTC’s own register: KalshiEX, LLC carries a real Designated Contract Market status, one that’s survived more than one legal challenge to date.
Fees scale with the contract itself — about 7% of the price, adjusted for how far it sits from a dollar — so a lopsided outcome barely costs you anything, while an even-money contract hits hardest.
Yes, down to zero, but not beyond it — I confirmed there’s no margin or borrowed-money trading available on what I tested, so your downside stops exactly at what you put in.
Almost. See the States Map above for the current, full list of where Kalshi operates.
It’s real regulation, not a marketing claim. The CFTC designation I verified directly against the agency’s own register, and Kalshi’s custody and clearing structure runs through a separately registered affiliate, Kalshi Klear LLC.
Venmo, in my experience — it cleared in minutes at zero cost every time I tried it. Routing the same withdrawal through a bank account instead took as long as 5 business days.
Yes, on both iOS and Android, and both are well-reviewed, 4.8 and 4.7 stars respectively. I hit exactly one glitch across my whole testing window.
I’d say yes, with a caveat: the welcome offer is easy to claim and the app itself is approachable, but the sheer number of markets can feel like a lot at first. Start with a category you already follow closely.
Where can I use Kalshi for predictions?
Kalshi is regulated at the Federal level, giving it nationwide access across most states. Besides the U.S., Kalshi is also accessible in over 140 countries, which is convenient for traveling users.
Kalshi is live!
