Are Prediction Markets Gambling? The 2026 Legal Grey Zone
New York is suing Kalshi for $36B as illegal gambling; the CFTC says federal law preempts that entirely. Why the fight doesn't touch offshore crypto casinos.

Kalshi is being sued for $36 billion. New York’s Attorney General calls it “running an illegal gambling operation.” The CFTC — the federal agency that licenses Kalshi — responded on August 11, 2026 by invoking emergency powers to order Kalshi to keep operating anyway. Two arms of the US government are, right now, giving directly contradictory answers to the same question: is a prediction market gambling?
If you’ve placed a Yes/No bet on Roobet, Metaspins, or another crypto casino’s Predictions tab, none of this fight is actually about you — but understanding why requires knowing what the fight actually is.
The Federal Argument: It’s a Derivative, Not a Bet
Kalshi operates as a Designated Contract Market (DCM) under the Commodity Futures Trading Commission — the same regulatory category as CME and ICE, the exchanges that list oil futures and interest-rate swaps.[1][2] That status matters because of what happened in court. When the CFTC tried to block Kalshi’s political event contracts in 2023, calling them gambling, Kalshi sued — and in September 2024 a federal district court sided with Kalshi, ruling its election contracts fit the Commodity Exchange Act’s definition of a derivative and don’t involve unlawful gaming. The CFTC dropped its appeal in May 2025, letting the ruling stand.[3]
The legal test isn’t “does this look like a bet.” It’s narrower: does the contract pay out based on an event “associated with a potential financial, economic, or commercial consequence”? In April 2026, a divided Third Circuit applied that same test to sports event contracts specifically — ruling in KalshiEX LLC v. Flaherty that they qualify as “swaps” under exclusive CFTC jurisdiction, triggering federal preemption of state gambling law.[4] The CFTC has since sued nine states directly — Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island, and Wisconsin — arguing its federal authority overrides their gaming statutes entirely.[5]
The State Argument: A Yes/No Bet Is Still a Bet
New York isn’t buying the derivative framing. On July 31, 2026, Attorney General Letitia James sued Kalshi in state court, alleging it’s “running an illegal gambling operation” without a state gaming license, and — separately — that it let under-21 users wager where state law sets the age floor at 21.[6] The suit asks the court to force Kalshi to forfeit its New York gains, pay restitution, and pay treble damages — the $36 billion figure. James put it plainly: “Prediction markets like Kalshi are gambling platforms, plain and simple. By ignoring our laws, Kalshi is running an illegal operation.”
Kalshi removed the case to federal court that same day, and the CFTC twice asked federal judges to block New York’s lawsuit outright — both times, it lost. Judge Jed Rakoff denied the request on August 4, finding the CFTC hadn’t shown it would likely win on the merits or suffer immediate harm; Judge Victor Marrero denied a renewed request on August 7.[7][8][9] Rather than accept those rulings, the CFTC used a different tool entirely: on August 11, 2026, it invoked its own emergency administrative authority under the Commodity Exchange Act — bypassing the courts that had just ruled against it — to order Kalshi to keep operating nationwide regardless. CFTC Chairman Michael Selig’s statement doesn’t hedge: “New York intends to make event contract derivatives waste away under its iron curtain of state gaming laws before the courts get the chance to issue final rulings,” adding that Congress never intended derivatives exchanges to run under “a patchwork of state gaming laws.”[10]
That’s the actual grey zone: not vague uncertainty, but two government bodies each asserting final authority over the same product, mid-litigation, with a real court date still ahead.
Where Polymarket Fits
Polymarket’s own regulatory history runs the same arc in miniature. The CFTC fined it $1.4 million in January 2022 for running unregistered event-based binary options and ordered it to wind down non-compliant markets[11] — after which Polymarket geoblocked US users from its main site rather than register. In July 2025, it spent $112 million acquiring QCX, a CFTC-licensed Designated Contract Market, rebuilding it as Polymarket US — a separate, US-facing, federally regulated product distinct from the offshore Polymarket.com that international users trade on.[12]
That split — regulated US entity vs. offshore original — is the actual dividing line in this fight, and it’s worth seeing plainly:
| Platform | Regulatory status | Who can use it |
|---|---|---|
| Kalshi | CFTC-registered Designated Contract Market | US residents (the entity currently being sued by New York) |
| Polymarket US (QCX) | CFTC-registered Designated Contract Market, since 2025 | US residents, onboarding through licensed brokerages |
| Polymarket.com | Offshore, geoblocked from the US since the 2022 settlement | Non-US users only |
| Roobet, BC.Game, Metaspins, Bets.io, Wild.io | Offshore crypto casinos, not licensed as US derivatives exchanges | Non-US users only — see our full breakdown of who’s actually running what |
The entire Kalshi-vs-New York fight plays out in the top row. Everything a crypto casino player actually touches is in the bottom two.
Why This Doesn’t Touch You on a Crypto Casino
The five casinos above all price directly off Polymarket’s own order book, and every one of them explicitly blocks American players — the same restriction Polymarket.com itself operates under, and for the same reason: none of them are licensed as a US derivatives exchange.
So the Kalshi-vs-New York fight, the nine-state CFTC lawsuit, the Third Circuit ruling — none of it changes whether a player in Brazil or Canada can trade a Yes/No share on Roobet. What actually governs that is the much more familiar question this site already covers: is offshore crypto gambling legal where you live, and does the casino itself have a track record worth trusting. The “is this gambling or a derivative” fight is a genuinely open, actively litigated US question — but it’s a US question, decided by US regulators, about a US-licensed product you can’t access from a no-KYC crypto casino to begin with.
Bottom Line
Two federal-vs-state actors are currently fighting over prediction markets in US courts, and neither side has a final answer — that’s a real, unresolved grey zone, not a settled fact you can be confidently wrong about. If you’re a US resident asking whether trading on Kalshi is legal, the honest answer right now is: the CFTC and a federal appeals court have each backed the derivative framing in separate cases, but a state attorney general is actively suing to shut it down as gambling, with $36 billion on the table and no final ruling yet on either front. If you’re playing prediction markets on a crypto casino instead, that fight isn’t yours — check the casino’s own restricted-country list and read its full review the way you would for any offshore operator, because that’s the legal question that actually applies to you.
