Score: A real, federally regulated exchange — where the money still comes from the other traders, roughly three out of four of them lose, and the company's biggest product is one court ruling away from being called gambling. Kalshi is not a scam and it is not a sportsbook. It is something newer and stranger: a stock-exchange-style market for yes/no questions about almost anything, valued at $40 billion as of October 29, 2026 — whose two founders were personally hit with felony charges the day before that valuation was announced. Both things are true at once, and that tension is the whole story.
Kalshi is the biggest regulated prediction market in the United States. You have probably seen its prices quoted on the news — "the market gives the Fed a 68% chance of cutting rates" is very often a Kalshi price. This is the BogusAPY walkthrough: what it actually is, how a trade works, who is behind it, the legal war over whether its sports contracts are just betting with extra steps, and the only question we ask about every product on this site — where does the money come from, and who ends up paying?
What Kalshi actually is
Kalshi's exchange company is KalshiEX LLC, and it holds a real federal license: the Commodity Futures Trading Commission (CFTC) designated it a Designated Contract Market (DCM) in November 2020 — the same license category as the Chicago Mercantile Exchange. Its clearing affiliate, Kalshi Klear LLC, became a registered Derivatives Clearing Organization in August 2024, so Kalshi now clears its own trades. This is not an offshore website with a terms-of-service page and a prayer. It is a US exchange, with a rulebook filed with a federal regulator.
That license comes with a superpower: a DCM can self-certify new contracts — file them with the CFTC and list them unless the regulator objects. Almost everything in this story, good and bad, flows from that one power. It is how Kalshi got election markets after a court fight, and how it launched sports contracts nationwide in January 2025 without asking any state for a gambling license.

How a contract works
Every Kalshi market is a yes/no question: Will the Fed cut rates in December? Will this team win? Will it rain in Chicago tomorrow? Contracts trade between 1¢ and 99¢ on an order book, and settle at exactly $1.00 if your side is right and $0.00 if it is wrong. The price is the probability, read straight off: a 68¢ YES contract is the market saying roughly 68%.
Three mechanics matter more than anything else:
- Your counterparty is another trader, not Kalshi. The exchange matches buyers and sellers and takes a fee. It never takes the other side of your trade — which is the structural difference from a sportsbook, where the house sets the odds, is your counterparty, and profits when you lose.
- Contracts are fully paid up front. You pay the full price when you buy, so the most you can lose is what you paid. There is no margin for regular users on event contracts — although in May 2026 the CFTC approved Kalshi listing margined crypto perpetual futures (BTCPERP), a separate, leveraged product line that is a different animal entirely. If you go anywhere near products like that, the same standard applies as on any leveraged crypto venue — our Kraken review covers what a clean record on a regulated exchange does and does not protect you from.
- You can sell before the event resolves. A position can be closed at whatever the order book offers, any time the market is open. A normal bet is locked in; a Kalshi contract is a position.
Position limits are set per market as maximum loss exposure. The standard retail limit on most event contracts is $25,000 per market; flagship macro contracts run far higher (the Fed rate-cut contract's limit is $7 million per member). Accounts are US residents 18 and up, with full ID verification, funded in dollars — bank transfer and wire are free, debit cards cost up to 2%, and crypto deposits get converted to dollars before you can trade. You never actually hold or trade crypto on Kalshi itself.
What trades there: economics (Fed decisions, inflation, jobs reports — the original product), elections, weather, entertainment, crypto prices, and, since January 2025, sports — which now dwarfs everything else, at roughly 80% of volume. Hold onto that number. It explains the lawsuits.
Who's behind it
Kalshi was founded in 2018 by Tarek Mansour and Luana Lopes Lara, who met as MIT undergraduates and went through Y Combinator's Winter 2019 batch. Their résumés are the institutional kind: Mansour interned at Goldman Sachs in 2016 — he tells the story that watching institutions struggle to hedge Brexit and the 2016 election on a trading floor is where the idea came from — then traded global macro at Citadel. Lopes Lara, a former professional ballerina in Austria before MIT, interned at Bridgewater Associates and as a quantitative trader at Five Rings Capital and Citadel Securities. The exchange launched publicly in July 2021, is headquartered in New York, and the name comes from the Arabic kal shi — "everything."
Neither founder has any fraud, blowup, or settlement history from before Kalshi — checked, and there is nothing there. Their careers before founding were short; both were about 22.
The money behind them is the bluest-chip list in finance: Sequoia led the 2021 Series A ($30M, alongside Henry Kravis and Charles Schwab investing personally), Paradigm led the $185M Series C in June 2025, and the rounds came faster and bigger — $5B valuation in October 2025, $11B that December, $22B in May 2026, and on October 29, 2026, a $1B Series G at a $40 billion valuation, co-led by Sequoia and Wellington Management. Mansour has ruled out an IPO in 2026.
Kalshi's post-money valuation by round — about $145M (Feb 2021) → $2B → $5B → $11B → $22B → $40B (Oct 29, 2026). Sources: company announcements and round reporting, checked Oct 31, 2026.
How much of that do the founders still own? Estimates conflict — Forbes reporting puts each founder's stake around ~12%, while New York Times reporting cited figures of 20–25% each (likely from before the 2026 rounds diluted them). Print the range, because that is all anyone outside the cap table actually knows: somewhere in that band, each.
One governance note worth having on the record, because this site checks who stands behind the referee: Brian Quintenz, a CFTC commissioner from 2017 to 2021, joined Kalshi's board in November 2021, months after leaving the Commission. He was later nominated to chair the CFTC, pledged to resign from Kalshi's board and divest if confirmed, and was never confirmed — Michael Selig ultimately got the job. Nothing about that was adjudicated as wrongdoing; it is reported here because a former regulator on the board of the company his old agency regulates is exactly the kind of fact readers deserve in plain sight.
The skeleton, at its true weight: both founders are under felony charges
On October 28, 2026 — one day before the $40B Series G was announced — Utah's Attorney General filed a criminal case naming KalshiEX LLC, Mansour, and Lopes Lara personally: 14 counts in total, made up of 1 second-degree felony (pattern of unlawful activity), 12 third-degree felonies (promoting online gambling), and 1 Class A misdemeanor.
The entire evidence base, per the filing, is an undercover agent from the AG's office who opened an account using Utah credentials and placed 12 sports wagers totaling $114.87 in September 2026. The founders were summoned, not arrested. Kalshi called the case a "crazy overreach."
Read that at exactly its true weight, no more and no less: charged is not convicted. Nothing has been tried, nothing has been proven, and the underlying dispute — whether federal derivatives law overrides state gambling law — is a genuine legal question that federal appeals courts are currently split on (next section). But it is also not nothing. Prosecutors do not usually charge a company's two founders personally over $114.87 unless they are making a point about who they believe is responsible, and any honest profile of this company in November 2026 has to lead its skeletons section with it.
Utah is not alone. In March 2026, Arizona's Attorney General filed a 20-count criminal complaint against the company (not the founders personally), alleging unlicensed wagering — including election betting, which Arizona bans outright. A federal judge declined in late October 2026 to stop Arizona from proceeding. Those are the criminal fronts. The civil fronts are an entire map, and they are the heart of the story.
Act 1: Kalshi beat its own regulator on elections
Kalshi self-certified contracts on which party would control Congress in 2023. The CFTC took the rare step of formally reviewing them and disapproved them in September 2023, finding they involved "gaming" and were contrary to the public interest.
Kalshi sued its own regulator — and won. In September 2024, a federal judge ruled the CFTC had exceeded its authority: congressional-control contracts do not involve gaming or unlawful activity under the Commodity Exchange Act. The appeals court refused to freeze the ruling, the contracts traded through the 2024 election, and after the change of administration the CFTC dropped its appeal entirely in May 2025. Final. Election markets on a regulated US exchange are legal because Kalshi fought for it and the government walked away.
The scale that fight unlocked: Kalshi's 2024 presidential-winner contract alone did about $535 million in volume — for years the most-traded single contract in company history.
Act 2: sports, and the states sue back
In January 2025 Kalshi used the same self-certification power to launch sports contracts nationwide — moneylines, spreads, totals, player props, multi-leg combos (its version of parlays) — in all 50 states, at 18+, with no state gambling license, no state gaming taxes, and no state problem-gambling funding. Nevada's gaming board sent the first cease-and-desist in March 2025. By early 2026, regulators or attorneys general in Nevada, New Jersey, Maryland, Arizona, Illinois, Montana, Ohio, Connecticut and more had sent orders or sued; Massachusetts' gaming commission put the state position in one sentence: buying Kalshi's sports contracts "is indistinguishable from the act of placing a sports wager." More than 20 states are now in litigation or enforcement against the company, and one Massachusetts judge, granting an injunction in January 2026, used the duck test: Kalshi offers parlays and player props, "mirrors other digital gambling experiences" and "borrows gambling terminology."
The federal appeals courts — the level that actually matters short of the Supreme Court — are split, and as of October 31, 2026 the split runs against Kalshi:
- 3rd Circuit — for Kalshi (April 6, 2026): a divided panel backed Kalshi in the New Jersey case, finding sports event contracts are likely "swaps" under federal law, which would put them under the CFTC's exclusive jurisdiction. New Jersey has asked the Supreme Court to take the case, and 39 state attorneys general filed a brief urging it to. The Court has not said yes or no yet.
- 6th Circuit — for the states (September 25, 2026): upheld Ohio and Tennessee's positions and went further — even if the contracts are swaps, federal law does not override state gambling regulation.
- 9th Circuit — for the states (August 28, 2026): affirmed Nevada's win, holding the sports contracts are not protected swaps as Kalshi claimed. The same circuit ruled for California tribes in September 2026 on their claim that the contracts violate federal Indian gaming law.
- 10th Circuit — for the states (September 8, 2026): refused to shield Kalshi from Utah's anti-gambling laws while its appeal runs.
One gaming attorney's running tally of rulings at every level put the states ahead in 35 of 41 rulings as of early September 2026. Almost all of this is preliminary — injunctions and stays, not final scores — and Kalshi keeps trading in most of the country while it plays out. But the shape is clear: Kalshi's one big appellate win is the case sitting on the Supreme Court's doorstep, and if the Court takes it and sides with the 39 AGs, the sports business — roughly 80% of volume and about 65% of revenue — gets geofenced or shut down in much of the US. That is the single largest fact about this company's future, bigger than any funding round.
Act 3: Washington picked a side
The referee is not neutral in this fight, and that is unusual enough to say plainly. Under Chairman Michael Selig, the CFTC has become an active combatant for the exchanges:
- It filed briefs supporting Kalshi's position in multiple state cases.
- Through 2026 it sued ten states itself — New York, Arizona, Connecticut, Illinois, New Mexico, Minnesota, Rhode Island, Wisconsin, Kentucky, and Utah (the last on October 27, 2026) — asking federal courts to declare state gambling law preempted.
- When New York sued Kalshi in July 2026 seeking a nationwide shutdown order and more than $36 billion in damages and penalties, Kalshi declared a market emergency, and on August 11, 2026 the CFTC used its emergency powers under §8a(9) of the Commodity Exchange Act to order KalshiEX to keep operating — only the seventh use of that power in the agency's history and the first since 1980.
The same CFTC is not a rubber stamp: its June 2026 proposal would restrict in-game micro-markets (pitch-by-pitch, first-basket props), and it has told smaller venues some of their self-certified contracts were false certifications. And Congress is circling — in late October 2026, Senators Warren and Curtis jointly demanded details from Kalshi and Polymarket on insider-trading and manipulation controls. Kalshi also announced new responsible-trading protections in October 2026, including spending limits for 18-to-20-year-old traders — a concession aimed at the states' strongest talking point, since sportsbooks are 21+ in most states and Kalshi is 18+.
Kalshi polices its own insiders, too
A prediction market lives or dies on whether the prices mean anything, and Kalshi's own enforcement disclosures show both the policing and the problem. On February 25, 2026 it published its first public insider-trading actions:
- Artem Kaptur, a video editor for MrBeast, traded about $4,000 across YouTube and streaming markets in August–September 2025 using non-public knowledge of upcoming videos. Surveillance flagged a near-perfect win rate on long-shot markets. He made $5,397.58. Sanction: give it back, plus a $15,000 penalty — $20,397.58 total — and a 2-year ban, with a referral to the CFTC.
- Kyle Langford, a former California gubernatorial candidate, traded about $200 on markets about his own candidacy and posted video of himself doing it. Sanction: $2,246.36 and a 5-year ban.
Three more congressional candidates were fined and banned for five years in April 2026, all for betting on their own races, all for under about $100 a trade. Kalshi says it opened 200+ insider-trading investigations in the year to February 2026 and 150+ more in the first quarter of 2026 alone, and made at least 20 referrals to law enforcement. Fair read: the surveillance is real, and so is the steady supply of people trying to beat markets with information the rest of the book doesn't have. One open question hangs over the numbers themselves: the Wall Street Journal reported in September 2026 that nearly a million trades in Kalshi's ether perpetual-futures market were clustered at a nearly identical size (~$5,500), accounting for over $5 billion of volume in a month. Kalshi says wash trading is banned in its rulebook, it found no evidence of it, and the sizes reflect an incentive program's design; the CFTC is examining the data. No finding has been made — allegation, denial, unresolved.
Are the prices any good?
Separate the products, because the answer splits cleanly down the middle.
The macro markets are genuinely good — the Fed's own researchers say so. A Federal Reserve staff paper (FEDS 2026-010, "Kalshi and the Rise of Macro Markets," February 2026 — staff views, not the Board's) studied roughly 86 million contracts across 176 macro events and found Kalshi's implied distributions well-calibrated and comparable to the New York Fed's survey and Bloomberg consensus, while updating continuously instead of once a month. Its headline numbers: Kalshi's median fed-funds forecasts had a perfect record the day before FOMC meetings in the sample, beating fed funds futures at that horizon, and its headline CPI error was 7 basis points versus Bloomberg consensus's 8. If you want to know what informed money thinks the Fed does next, this is now one of the best public instruments there is.
The extremes are where the prices lie to you. The same research literature documents a strong favorite–longshot bias: across 300,000+ Kalshi contracts, contracts priced at 10¢ or less paid out far less often than their prices imply — average losses above 60% on those cheap contracts — while contracts above 50¢ earned small positive average returns. An independent cross-platform study of 358,236 resolved markets found favorites won 76.9% of the time the day before resolution overall, but only 65.9% in genuinely uncertain markets. The market is well calibrated in the middle and systematically wrong at the sexy extremes — which is exactly where casual users like to play, because 8¢ tickets that "pay 12-to-1" feel like lottery tickets with a chart.
Where the money actually comes from
This is the section this site exists for. Kalshi event contracts are zero-sum between traders, and negative-sum after fees. Nobody prints a yield. Every dollar a winner withdraws is a dollar a loser deposited, minus the toll. Kalshi's toll in 2025 was about $263.5 million in trading fees — roughly 89% of it from sports. The house doesn't bet against you. The house doesn't have to.
The fee itself is a formula, from Kalshi's own fee schedule (effective July 7, 2026). For a taker — an order that matches immediately:
fee = round up (0.07 × contracts × price × (1 − price))
Resting (maker) orders are usually free. There is no settlement fee. Kalshi's own worked examples: 100 contracts at 50¢ cost $1.75 in fees; at 10¢, $0.63; at 99¢, $0.07. The bite peaks at 50¢ — a coin flip — which is exactly where sports markets live.
Now run a full trade, using that formula, so you can check every number:
You buy 100 YES contracts at 60¢ on "Will the Fed cut rates in December?"
- Contract cost: 100 × $0.60 = $60.00
- Taker fee: 0.07 × 100 × 0.60 × 0.40 = $1.68
- Total cash in: $61.68
- If YES happens: you receive 100 × $1.00 = $100 → profit +$38.32
- If NO happens: you receive $0 → you lose the full −$61.68
And the quiet part: the screen said 60¢, a "60% implied probability." After the fee, your breakeven is $61.68 ÷ $100 = 61.7%. You need the true odds to be at least ~62%, not 60%, just to break even — before the bid-ask spread you crossed to get filled, which in thin markets costs more than the fee does. That gap is where the money comes from. It comes from you, and it goes to the exchange and the trader on the other side of your trade.
How does the average trader actually do? Kalshi itself gave the cleanest number: it admitted to the Wall Street Journal (May 2026) that losing traders outnumber winning traders roughly 2.9 to 1 — only about 1 in 4 traders is profitable. Academic analysis of Kalshi trade data (Bürgi, Deng & Whelan, 2026) found market takers lose about 32% of capital on average, with fees and the longshot bias doing most of the damage; taker fees alone can eat up to 56% of a winning cheap contract's gross profit.
One bigger number is publicly fought over, and we print it as a fight, not a fact: the Roosevelt Institute (September 2026) analyzed Kalshi's public trade data from launch through May 2026 and estimated ordinary taker users lost $583.5 million net in aggregate. Kalshi's public rebuttal called the study "hilariously wrong," arguing it misclassifies institutional market-maker flow as ordinary users, and noting professionals generate ~97% of volume. Both things can be partly true — the retail slice is small in volume and real in dollars — but the $583.5M figure is contested, not settled, and anyone quoting it without the rebuttal is selling you something.
How does the cost compare to a sportsbook? Better than you'd expect in one narrow case, worse in the rest. At 50¢, the $1.75 fee per $100 of contracts works out to roughly −107 odds — slightly cheaper than a sportsbook's standard −110, if you get filled at the mid-price and ignore the spread. But the fee is charged again if you sell early, thin-market spreads are often several cents wide, and at longshot prices the fee shrinks while the favorite–longshot bias does the damage instead. Honest summary: Kalshi is cheaper than a sportsbook for liquid, near-50¢ markets traded patiently; it can be more expensive for takers in thin or gimmick markets. "Mention markets" — will a celebrity's name get said during a broadcast — are the gimmick end: one rumor-driven market on whether Mark Wahlberg would attend Super Bowl LX drew $23.7M, spiked to 89%, then collapsed when he didn't show.
The scale, for the record, with the yardsticks kept honest: full-year 2025 volume is estimated at ~$17.1B to ~$23.8B depending on the tracker — sources conflict, so we print the range. The record month was ~$60.7 billion in September 2026. The biggest single markets: the 2024 presidential winner at ~$535M, and the 2026 Masters at ~$545M across the tournament. The company claimed at the Series G that annualized volume across all its businesses now exceeds $1 trillion — that figure folds in the new perps and crypto lines, not just event contracts, and it is a company claim, not an audited number.
How you'd actually trade it
Sign up at kalshi.com or in the app (US resident, 18+, full ID check). Deposit dollars by bank transfer or wire for free, debit card for up to 2%, or crypto that gets converted to dollars first. Pick a market and a side — YES or NO, price in cents. A market order makes you a taker and charges the fee; a resting limit order makes you a maker and is usually free. Then hold to settlement ($1 or $0 per contract, no settlement fee) or sell any time the book is open. Winnings are taxable; expect tax forms. And remember the standard retail cap: $25,000 maximum loss per market.
The bottom line
Kalshi is two things at once, and the honest review keeps both in frame. It is a real, federally licensed exchange whose macro markets are good enough that Federal Reserve researchers cite them alongside Bloomberg — a genuine forecasting instrument that did not exist five years ago. And it is a negative-sum trading pit where the exchange collected ~$263.5M in 2025 fees, roughly three losers fund every winner by the company's own admission, the cheapest tickets are the worst deals on the board, and the dominant product — sports — is currently losing in three federal appeals courts, with both founders personally charged with felonies in Utah over $114.87 of undercover wagers.
If you use it, use it the way the math says: liquid markets near 50¢, limit orders, position sizes you'd shrug at losing, and a hard rule against the 8¢ lottery tickets. The probability on the screen is the market's opinion, not your edge. Your edge, if you have one, has to beat the price plus the fee plus the spread — and about three out of four traders on the platform don't.
