Kalshi is a federally regulated exchange, not an offshore sportsbook with a slick app. That is the short answer, and it is worth stating plainly because the question gets asked constantly and the honest reply is more reassuring than most of this category deserves.
The longer answer has caveats, and some of them matter. This covers what Kalshi's licence actually protects, what it does not, where your money sits, what the company's finances look like, and the specific risks that remain even on a properly regulated venue.
What Kalshi's regulation actually means
Kalshi holds a designated contract market licence from the Commodity Futures Trading Commission. A DCM is the same category of licence held by CME and ICE — the venues where oil futures and interest rate swaps trade. It is not a gaming licence, and it is not a state-by-state permission. It is a federal exchange registration.
That distinction carries three practical consequences.
The first is oversight. A DCM files rulebooks with the CFTC, submits contracts for review, and operates under federal market integrity rules. When Kalshi lists a contract on an election or an economic release, that contract has been through a process. Compare that with an offshore book, where the only document governing your money is a terms page the operator wrote and can rewrite.
The second is segregation. Customer funds at a DCM are held separately from the company's own operating money. If Kalshi the business ran into trouble tomorrow, customer balances are not supposed to be available to its creditors. "Not supposed to be" is doing real work in that sentence — segregation is a legal requirement, not a physical vault — but it is a materially stronger position than an unregulated platform offers.
The third is that it is checkable. Kalshi's registration is public record. You can verify it rather than trusting a badge on a homepage.
Where your money sits
Kalshi settles in US dollars. You fund the account from a bank, you trade in dollars, and you withdraw dollars. There is no stablecoin, no wallet, no bridge, and no chain that can congest at the wrong moment — which is the structural difference from Polymarket and the reason many US traders pick it.
Idle cash earns roughly 4% APY. That is unusual in this category and worth understanding properly: it means capital parked between trades is doing something, which over a year of holding positions can outweigh the difference in trading fees entirely. Our Kalshi fees explainer works through where that lands against the per-contract charge.
Deposits and withdrawals both run through the banking system rather than a crypto rail, so they are traceable, reversible in the cases where reversal applies, and covered by the usual consumer protections on the bank's side.
Is the company financially solid?
Kalshi raised $1 billion in a Series E at an $11 billion valuation in December 2025, and reported roughly $260 million in revenue for that year. Monthly volume runs near $9.8 billion. Reporting has put the company in conversations about a valuation near $20 billion.
Those numbers matter for a specific reason: a venue that is running out of money has an incentive to behave badly, and one that is compounding does not. Kalshi is not a startup hoping to survive the quarter.
What the licence does not protect you from
This is where honesty is more useful than reassurance.
It does not stop you losing money. Event contracts are zero-sum. Regulation governs how the market operates, not whether your opinion about the Chiefs is correct. Most retail participants lose over time, and a federal licence does nothing to change that.
It is not FDIC insurance. Segregated funds are protected from the company's creditors in a bankruptcy; they are not insured against loss the way a bank deposit is. There is no federal backstop that makes you whole if something goes wrong at the exchange level.
It does not settle the state-law fight. Several states have challenged whether sports event contracts belong under CFTC jurisdiction at all. Arizona filed criminal charges against Kalshi in March 2026. Tennessee ruled in Kalshi's favour; Nevada, Massachusetts, Maryland and Ohio ruled against. That fight is live, and an adverse outcome could change availability where you live — the current state of play is in our guide to prediction market legality.
It does not guarantee the market resolves the way you expect. Contracts settle according to the rulebook, not according to what seems obvious. Read the resolution criteria before you trade anything ambiguous.
Where Kalshi is available
Kalshi operates in more than 40 US states. Availability is not universal, and it has moved as the state-level litigation has progressed. Check your own state before funding an account rather than assuming.
The platform is US-focused. If you are outside the United States, Kalshi is generally not the venue for you, and the alternatives in our best prediction market apps roundup will be more relevant.
How it compares on safety
| Kalshi | Polymarket | Offshore books | |
|---|---|---|---|
| Regulator | CFTC (DCM) | CFTC-licensed via acquisition | None meaningful |
| Settlement | US dollars | USDC on Polygon | Varies |
| Fund segregation | Required | Required | Not required |
| Interest on idle cash | ~4% APY | None | None |
| Identity verification | Yes | Yes | Often minimal |
| Recourse if something breaks | Federal regulator | Federal regulator | Practically none |
Kalshi and Polymarket now sit in broadly the same regulatory tier, which was not true two years ago. The differences that remain are about money rails and market breadth rather than legitimacy — covered in full in our Polymarket vs Kalshi comparison.
Practical checks before you fund an account
Verify your state is covered. Read the resolution criteria on the first contract you intend to trade, so the habit forms early. Start with an amount you would not mind losing entirely, because the first few trades are tuition regardless of how the markets are regulated. And understand the tax position before you have a profit to report — Kalshi issues a 1099-MISC, and our prediction market tax guide covers the treatments people actually use.
If you want to see what you would actually pay on a trade before placing one, our fee calculator runs the published formula against any position size.
Verdict
Kalshi is legitimate by every check that can be made from outside: a federal exchange licence, segregated customer funds, dollar settlement through the banking system, a billion-dollar balance sheet and public registration you can verify yourself. On the question people are actually asking — will this platform take my money and vanish — the answer is no.
What remains is ordinary market risk, an unsettled fight over state jurisdiction, and the fact that most people who trade event contracts lose. Those are real, and no licence fixes them. Our full Kalshi review covers how the platform performs as a place to trade rather than as a place to keep money.
Frequently Asked Questions
Is Kalshi legal in the United States?
Yes. Kalshi operates as a CFTC-designated contract market, a federal exchange licence, and is available in more than 40 states. Several states have contested whether sports event contracts fall under federal jurisdiction, so availability varies — see our legality guide.
Is my money safe on Kalshi?
Customer funds are held segregated from company money as required of a designated contract market, and settle in US dollars through the banking system. That protects balances from company creditors, but it is not FDIC insurance and does not protect you from losing money on trades.
Does Kalshi pay interest on my balance?
Yes, roughly 4% APY on uninvested cash. Over a year of holding positions that can be worth more than the difference in trading fees between venues — the maths is in our Kalshi fees explainer.
Has Kalshi ever failed to pay out?
There is no record of Kalshi failing to settle contracts according to its rulebook. Disputes that do arise concern how a contract's resolution criteria apply to an ambiguous event, not whether the platform pays.
Is Kalshi better than Polymarket?
Neither is better outright. Kalshi settles in dollars, pays interest on idle cash and needs no crypto wallet; Polymarket runs deeper books and lists more markets. Our head-to-head comparison sets out the trade-offs.
Do I have to pay tax on Kalshi profits?
Yes. Kalshi issues a 1099-MISC on winnings, and profits are reportable regardless. The IRS has published no guidance specific to prediction markets, so treatment varies — see our tax guide and take-home calculator.
