Is Kalshi legit? Yes, it is a CFTC-designated contract market, with three caveats (August 2026)

Yes. Kalshi operates as a designated contract market (DCM), which is the Commodity Futures Trading Commission's own category for a federally regulated exchange, and you can confirm it on the Commission's public register instead of taking any website's word for it. That answers the question most people mean by "legit". It does not answer three others, and all three have numbers attached: 174 of the 214 complaints on Kalshi's Better Business Bureau profile are recorded as closed without a response from the business, which is 81%; at least six state-level actions landed on prediction market contracts during 2026; and Kalshi writes the settlement rules for its own contracts with no independent intermediary, which is the Massachusetts Attorney General's characterisation of the arrangement, not ours.

Regulated means a specific thing, and it is narrower than most pages imply

A designated contract market is a federally regulated exchange registered with the CFTC. The register is public. If you want to verify Kalshi's status yourself, that register is the document to look at, and it is the only document that settles the point. Everything else you will read on this query is somebody's summary of it.

What DCM status covers: the venue itself is a federally regulated exchange rather than an unregistered offshore book.

What DCM status does not cover, and this is where nearly every page on this SERP stops:

1. It is not a ruling that trading is lawful in your state. Federal registration and state gambling law are separate questions and they have produced separate answers in 2026.
2. It is not a service-level guarantee. A federally regulated exchange can still leave 81% of its BBB complaints unanswered, and that is what the record shows.
3. It is not an independent settlement appeal. Kalshi is the resolution source for its own contracts.

The strongest number on this page is the one no affiliate will print

Kalshi's Better Business Bureau profile records 214 complaints, of which 174 are closed without a response from the business. That is 81%.

Name the metric precisely, because this is where these pages usually cheat. That figure is a count of complaints the business did not answer through the BBB channel. It says nothing about how many of those problems were eventually resolved, and it is not a satisfaction or fraud rate. A complaint on the BBB is a one-sided account by definition.

It also has no denominator. Kalshi does not publish an active-trader count anywhere we have found, so 214 complaints cannot be converted into a per-user rate. Anyone who tells you it can is making up the denominator. What the 81% does measure, cleanly, is responsiveness: on the public channel where a business chooses whether to reply, Kalshi did not reply about four times out of five.

The dominant theme in the one-star complaint record on both the BBB and Trustpilot is withdrawals and KYC holds. One documented case in that record has identity documents submitted on 10 January and still unverified on 23 January, thirteen days. Our note on that case does not record which platform's profile it was read from, so read it as a pattern in the complaint corpus rather than a stamped Kalshi incident.

Every page ranking for this keyword that carries a signup link has a structural reason not to publish that 81%. That is not a conspiracy claim, it is an incentive observation, and you should apply it to us too. See the disclosure at the bottom.

State legality is a separate question, and the answers published in 2026 contradict each other

At least six state-level actions hit prediction market contracts during 2026. Our notes record Massachusetts contracts enjoined, Nevada under injunction, a $5 million fine connected to Ohio (issuing body and order number unverified), cease-and-desists issued in Connecticut, Minnesota's SF 3432 taking effect on 1 August 2026, and Illinois SB 3019.

We have not pulled the dockets for any of those. Treat the list as a pointer, not a citation, until the per-state pages carrying case caption, court, docket number and last docket event are live. That is the standard we hold other people to on this exact subject, so it applies here first.

What we can show you is that the pages currently answering this question disagree with each other. Auditing eleven competitor state-legality pages in late July 2026, four publishers writing in the same week produced these contradictions:

The root cause is not carelessness. Three different questions are being answered as if they were one:

• Is it lawful for me to trade here? A question of state law.
• Is the platform geofenced for my state? A question of platform policy.
• Am I eligible for the promo? A question of marketing terms.

At least one of those competitor pages was publishing an explicit promo-eligibility list under a heading about legality. Keep the three apart and every contradiction in the table above resolves.

The fee is a parabola, and the rounding rule punishes small longshot orders

Kalshi's taker fee rate is 0.07, applied through the formula roundup(0.07 × C × P × (1 − P)), where C is the number of contracts and P is the price in dollars. The result is in dollars and rounds up to the next whole cent. Figures below are from our fee model at schedule version 2026-08-04.a.

The P × (1 − P) term is a parabola, so the fee peaks in the middle of the board and falls away at both ends. Per 100 contracts:

A worked round trip. Buy 100 contracts at $0.60, sell them at $0.66, both as taker fills.

• Entry fee: 0.07 × 100 × 0.60 × 0.40 = $1.68
• Exit fee: 0.07 × 100 × 0.66 × 0.34 = $1.5708, rounded up to $1.58
• Gross gain: 100 × $0.06 = $6.00
• Fees: $3.26
• Net: $2.74. Fees took 54% of the gross move.

Now the part almost nobody publishes. Break-even as a share of stake is rate × (1 − P), because the contract count cancels the price. That makes the cheap end of the board the expensive end in percentage terms:

• At $0.90, break-even needs a 0.7% move.
• At $0.60, it needs 2.8%.
• At $0.03, it needs 6.79%.

Then the rounding rule makes small orders in the longshot corner of the board worse still. One contract at $0.03 generates a raw fee of $0.002037, which rounds up to a full cent. You pay 4.9 times the unrounded rate, and that penny is 33% of your $0.03 stake. The same order at $0.50 rounds 1.75c up to 2c, a multiplier of 1.14 and 4% of stake.

This is the opposite of the intuition that cheap contracts are the low-risk way in. On our own numbers the fee-adjusted break-even for a Kalshi leg computes to 3.63%, while our scanner still publishes a flat 1.0% minimum edge threshold. That gap is a defect in our tool, not a finding about Kalshi, and we only found it after the first real fee arithmetic killed a position our own scanner had opened. The threshold fix has not shipped.

Kalshi's HTML fee page is a stub that redirects to a rate-limited PDF. No fee table, no per-price grid and no worked examples exist on the indexable web, which is the only reason a grid this basic is worth publishing.

Kalshi's own documentation contradicts itself on maker fees

Kalshi's newsroom states that resting orders are fee-exempt. Kalshi's help centre states that maker fees are charged. Both are Kalshi's own publications and we have found no public reconciliation of the two.

This matters if you post limit orders rather than taking the spread, which is exactly the population most likely to care about the answer. We are not going to guess which one is current. It is on the list below, and the only honest resolution is a direct answer from Kalshi.

Separately, Kalshi acknowledges that special-event fee tiers exist, naming elections, awards ceremonies and large sporting championships. The rates for those tiers are not quantified anywhere public.

The referral programme is where the marketing stops matching the terms

Read direct from Kalshi's Referral Program FAQ on 5 August 2026:

• Referral credits are not cash. Only profits made trading with them become withdrawable.
• Credits expire 7 days from issuance unless otherwise specified, or they are forfeited.
• The code must be entered within 72 hours of account creation and before the first deposit, whichever comes first.
• The programme is US only. International users are not eligible.
• A lifetime cap on referral earnings per account exists. The amount is not published.
• The referred user must meet a trading requirement shown in their own Rewards section. The size is account-specific and visible in-app only.

For contrast, third-party affiliate pages were publishing "up to $25 per referral" and "lifetime commissions up to 30%" for this programme. Kalshi's own FAQ publishes neither figure, nor any percentage, nor any payout amount. It says reward amounts vary by programme and can change between referrals.

One more example of how badly this subject is being summarised: a Google AI Overview described Kalshi as running "custom promotional partnerships with select media publishers", which reads as something an independent site could join. The publicly documented partners are CNN, CNBC, FOX, Madison Square Garden, the Chicago Blackhawks and Men in Blazers. Those are negotiated brand deals. There is no application form and no rate card.

What we could not verify

This section is the point of the page.

• Docket numbers and case captions for every state action listed above. We hold the outcomes in note form and have not pulled the filings. The $5 million Ohio figure in particular is recorded in our notes without the issuing body or an order number.
• The read date on the BBB figure. The 174-of-214 count comes from our own source review of Kalshi's BBB profile, but our notes do not preserve the exact date it was read. Complaint counts move. Re-check it before relying on it.
• A Trustpilot score of 1.9 out of 5 appears in our research notes for this niche, but the note does not record which platform's profile it was read from or how many reviews it covers. We are not attributing it to Kalshi on that basis.
• Kalshi's user count. Not published anywhere we have found, which is why the 214 complaints have no denominator.
• Special-event fee tiers. Acknowledged by Kalshi to exist, never quantified publicly.
• Where customer money sits. We have not verified custody arrangements or fund segregation and are not going to imply an answer.
• Whether Kalshi works with independent publishers at all. kalshi.com/affiliates has returned HTTP 429 on four separate attempts across this project. No content from that URL has ever been retrieved by us.
• The maker fee contradiction. Newsroom and help centre disagree. Unresolved.
• A list of US states in which the referral programme is said to be unavailable circulates on affiliate sites. Kalshi's own help page states no such list. We have not verified it and we are not repeating it until we can.

Nobody pays us for this page, and our own trade log is down $28.30

PredictionEdge currently takes no referral revenue, and whether it ever will is undecided. There is no Kalshi referral code on this page. Kalshi's published referral programme is an ordinary user refer-a-friend scheme, by its own framing, and we have found no application form, no rate card and no self-serve tier for publishers. Whether a publisher route exists behind kalshi.com/affiliates is on the unverified list below, because that URL has never loaded for us.

Our own paper trade log is public and it is not flattering: 10 trades, 6 closed, net −$28.30 on $500 deployed as of 4 August 2026. One of those positions was arithmetically unwinnable at the moment of entry: opened on a claimed 1.20% edge at an entry price of $0.2965, where fee-adjusted break-even is 2.81% of stake. The cause is a flat edge threshold in our own scanner that ignores the price-dependence of the fee. That threshold has not been replaced yet, and the trade stays in the log. The scanner is a momentum detector, not an arbitrage detector, and we say so rather than let the word do work it has not earned.

If a page tells you a platform is legit and cannot tell you what it gets paid, that is the first thing to check about the page.

The eight questions people actually type before signing up

Is Kalshi regulated by the CFTC? Yes. Kalshi operates as a designated contract market, the CFTC's category for a federally regulated exchange, and appears on the Commission's public register of DCMs. That is a federal registration covering the venue. It is not a state-law ruling and not a guarantee about support, settlement disputes or withdrawal timing, all of which are separate.

Is Kalshi a scam? No, not in the sense of an unregistered offshore operation that takes deposits and disappears. It is a CFTC-designated contract market. The documented problems are different in kind: 174 of 214 BBB complaints closed with no response from the business, withdrawal and KYC holds as the dominant one-star theme, and no independent appeal on a disputed settlement.

Why are there so many complaints if Kalshi is regulated? Because federal registration regulates the venue, not the customer service. Kalshi's BBB profile shows 214 complaints with 174 closed unanswered, which is 81%. Those complaints cluster on withdrawals and identity verification holds. A designated contract market registration says nothing about how fast a support ticket is answered, or whether it is answered at all.

Can Kalshi decide how my contract settles? Yes. Kalshi is the resolution source for its own contracts, so one party writes the rules and decides the outcome. The Massachusetts Attorney General's complaint describes Kalshi as writing the rules for the contract and determining the basis for settlement, with no independent intermediary. We have found zero documented appeal paths outside Kalshi itself.

How much does Kalshi actually charge per trade? The taker fee is roundup(0.07 × C × P × (1 − P)), rounded up to the next cent. That peaks at 1.75 cents per contract at a $0.50 price and falls to 0.34 cents at $0.05 or $0.95. On a 100-contract round trip bought at $0.60 and sold at $0.66, fees are $3.26 against a $6.00 gross move.

Are cheap contracts the safe way to start? Not on fee arithmetic. Break-even as a share of stake is rate × (1 − P), so a $0.90 contract needs a 0.7% move to clear fees while a $0.03 contract needs 6.79%. Rounding makes it worse: a single $0.03 contract pays a full cent, which is 4.9 times the unrounded fee and 33% of your stake.

Does the Kalshi referral bonus pay real money? Not directly. Kalshi's own FAQ says referral credits are not cash and only profits made trading with them become withdrawable. Credits expire 7 days from issuance, the code must be entered within 72 hours of signup and before the first deposit, and the programme is US only. Kalshi publishes no payout amount.

Is Kalshi legal in my state? That depends on your state and it is a different question from CFTC registration. At least six state-level actions landed in 2026, including Minnesota's SF 3432 effective 1 August 2026. Published state lists contradict each other on Montana, Illinois, New Jersey, Minnesota and Connecticut, usually by mixing up legality with promo eligibility.
