Read the disagreement precisely, because it is narrower than it looks. The Ninth Circuit did not reject preemption. It agreed with the Third Circuit that the Commodity Exchange Act is a comprehensive scheme that preempts state law regulating futures trading, and it declined to apply any presumption against preemption. That divergence turns on a prior question — whether these contracts are the instruments the statute reaches at all. The Sixth Circuit, deciding on September 25, 2026, took both paths: it held the contracts are not shown to be swaps, and alternatively that even swaps would not displace state gambling law — so on the question of preemption itself, it is the first circuit to rule outright against the platforms. All three rulings are also preliminary-injunction decisions reviewed for abuse of discretion, not final judgments on the merits. The single ruling on this page that is a merits judgment came from a district court in Utah.
The Path to the Supreme Court
A 2023 order against one election market became a fight over whether federal commodities law wiped out state gambling law. Three federal appeals courts have now answered it — one for the platforms, two against — and 3 petitions now ask the Supreme Court to settle it.

The split, in its sharpest form
Third Circuit · argued Sept 10, 2025 · decided Apr 6, 2026
Chagares, C.J., Porter & Roth, JJ. — opinion by Porter, Roth, J. dissenting
Sports contracts are swaps.
The statute only asks that an event be “associated with” a financial consequence — sponsors, networks, and franchises supply that. Injunction affirmed, 2–1, for the platforms.
Ninth Circuit · argued Apr 16, 2026 · decided Aug 28, 2026
R. Nelson, Bade & Lee, JJ. — opinion by R. Nelson, Lee, J. concurring
Sports contracts are not swaps.
They were sports bets — and a CFTC regulation already bars gaming contracts outright. Affirmed on sports contracts; Kalshi’s election contracts remanded, not decided.
Amici against Kalshi: 39 states and D.C., the American Gaming Association, Better Markets, and two problem-gambling organizations.
The Ninth Circuit’s opinion opens by quoting Kalshi’s own marketing: it “advertises itself as ‘the first app for legal sports betting in all 50 states.’”
On September 25, 2026 the Sixth Circuit sided with the Ninth, ruling for Ohio and Tennessee (Clay, Gibbons & Bloomekatz, JJ.; opinion by Gibbons). It went further than either court above: even if the contracts were swaps, it held, the Commodity Exchange Act would not preempt state gambling law.
Where it stands
“Whether the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act preempted States from regulating sports bets that occur within their jurisdictions if those bets are offered on markets registered with the Commodity Futures Trading Commission.”
Question presented — Petition for a writ of certiorari, Flaherty v. KalshiEX, LLC, No. 26-299, filed September 2, 2026; Kalshi’s response due December 7, 2026.
How it got here
- September 2023. The CFTC orders Kalshi not to list contracts on control of Congress.
- September 2024. The U.S. District Court for D.C. (Judge Cobb) vacates that order — a win for the platform.
- May 2025. The CFTC voluntarily dismisses its own appeal. No appellate ruling on the order was ever issued.
- April 6, 2026. The Third Circuit, in Flaherty (172 F.4th 220), affirms the injunction for the platform, 2–1, Judge Roth dissenting.
- August 28, 2026. The Ninth Circuit, in Assad (No. 25-7516, published), affirms dissolution of the injunction against the platform on sports contracts, and remands the election-contract question.
- September 2, 2026. New Jersey petitions the Supreme Court for certiorari in Flaherty v. KalshiEX, LLC, No. 26-299 — review of the Third Circuit, for the platform. Response due December 7, 2026.
- September 10, 2026. Robinhood petitions the Supreme Court for certiorari in Robinhood Derivatives, LLC v. Dreitzer, No. 26-338 — review of the Ninth Circuit, against the platform. Response due November 13, 2026.
- September 11, 2026. Crypto.com petitions the Supreme Court for certiorari in North American Derivatives Exchange, Inc. v. Nevada, No. 26-344 — review of the Ninth Circuit, against the platform. Response due November 16, 2026.
- Running in parallel, 5 more circuit appeals are undecided: the Second Circuit (Kalshi’s New York and Connecticut appeals and Coinbase’s Connecticut appeal (Nos. 26-1835, 26-2239 and 26-2297), heard in tandem. On November 3, 2026 one panel denied all three motions for an injunction pending appeal after argument, without reaching the merits, so neither state is barred from enforcing while the appeals run. Connecticut’s merits briefs are due November 20; New York filed its brief October 30. Undecided.); the Fourth Circuit (Maryland, argued May 7, 2026 and still undecided as of November 8. Kalshi has asked the panel to wait for the CFTC’s pending rules (the revised Rule 40.11 and the October 2026 swap-definition proposal) if it is uncertain. Kalshi lost below.); the Seventh Circuit (Three appeals from the Wisconsin order, consolidated; opening briefs were filed September 21, 2026, Wisconsin and the federal government filed their response briefs October 28, and replies are due November 19. Illinois appealed the October 30 preliminary injunction against it (No. 26-3266 in the federal government’s case), so the court now has both sides of an in-circuit split at the district level. Separately, on October 27 the court granted Kalshi permission to appeal the Ho-Chunk Nation’s IGRA ruling (No. 26-8020) and denied the Nation’s cross-petition.); the Eighth Circuit (Iowa: Kalshi appealed the September 8 denial of its injunction (No. 26-2874). On Kalshi’s motion its opening brief is now due December 7, 2026. The first time the question has reached this circuit; Novig, Crypto.com’s exchange and Kalshi have since sued Missouri, in the same circuit.); the Tenth Circuit (Utah: the only appeal from a final judgment (No. 26-4100). The court refused an injunction pending appeal on September 8, 2026; Kalshi filed its opening brief September 21, Utah answered, and on October 28 and 29 amicus briefs supporting Utah were filed, led by one from 37 states. The United States and the CFTC have since sued Utah in the district court, and Utah has filed criminal charges against Kalshi.)
The two rulings that made the split
KalshiEX LLC v. Flaherty
Third Circuit · April 6, 2026 · 2-1, Roth, J. dissenting · 172 F.4th 220

The laws in play
Congress first regulated futures in the Grain Futures Act of 1922, after regulators found the markets “susceptible to speculation, manipulation, and control” (Bd. of Trade of Chicago v. Olsen, 262 U.S. 1, 37 (1923)). Renamed the Commodity Exchange Act (CEA) in 1936, its 1974 amendments created the CFTC and gave it “exclusive jurisdiction,” codified at 7 U.S.C. § 2. Dodd-Frank added “swaps” to that jurisdiction in 2010 and wrote in the Special Rule the two circuits now read differently.
| Provision | What it does |
|---|---|
| 7 U.S.C. § 1a(47)(A)(ii) | Defines “swap” — needs only an event “associated with a potential financial, economic, or commercial consequence.” This is the crux of the split. |
| 7 U.S.C. § 2(a)(1)(A) | Gives the CFTC exclusive jurisdiction over swaps traded or executed on a designated contract market. |
| 7 U.S.C. § 7a-2(c)(5)(C)(i)–(ii) | The Special Rule. The CFTC may find a swap contrary to the public interest if it involves “activity that is unlawful under any Federal or State law, terrorism, assassination, war, gaming, or other similar activity.” |
| 17 C.F.R. § 40.11(a) | The CFTC’s own regulation categorically prohibiting swaps involving gaming — the rule the Ninth Circuit held Kalshi’s self-certification violated. |
| 7 U.S.C. § 16(e)(1)(B)(i) | Savings clause — the Act does not preempt state law for transactions not on a registered entity. |
| 15 U.S.C. § 8302(d)(1) | Congress’s delegation to the CFTC and SEC to “further define” swaps. |
| U.S. Const. art. VI, cl. 2 | The Supremacy Clause — the basis for any federal preemption of state gambling law. |
The states enforce their own statutes against this: New Jersey’s gambling law (N.J. Stat. Ann. §§ 5:12A-11(c), 2C:43-2 — a fourth-degree crime, fines up to $100,000) in Flaherty, and Nevada’s gaming statutes and regulations in Assad. See “The arguments, both ways” below for how the two circuits read the swap definition and the Special Rule against each other.
The arguments, both ways
Is a sports event contract a “swap”?
The platforms & the CFTC
The words do the work. A sports outcome is an “event” in ordinary usage, and the Third Circuit held the analysis stops there: the outcome of a sports event “certainly can be associated with a potential financial, economic, or commercial consequence.” Sponsors, networks, franchises and local economies all carry real exposure to it.
The states
Reading “event” to mean “outcome” makes the statute’s own use of “occurrence” surplusage, and dictionaries mark that sense as archaic. The Ninth Circuit required the event be inherently associated with a financial consequence, since any downstream consequence would “render the definition of swap so broad as to be meaningless.”
Does the reading have a limiting principle?
The platforms & the CFTC
Congress gave the CFTC power to “further define” swaps, so an agency rather than a court can police the edges. Kalshi has not asked any court to hold that ordinary sports bets are swaps.
The states
This is the sharpest point against the platforms. Section 2(e) makes it unlawful to enter a swap off a designated market — so if a sports bet is a swap, then “every person placing a sports bet at Caesar’s Sportsbook … is violating the CEA.” The Ninth Circuit noted the Third Circuit acknowledged this and did not resolve it.
What work does the Special Rule on “gaming” do?
The platforms & the CFTC
The Special Rule says the Commission may determine that a contract is contrary to the public interest — permissive, not self-executing. Judge Lee, concurring in the Ninth Circuit, agreed it “does not seem to categorically bar all gaming contracts,” and allowed that “perhaps some unique sports events can be part of a swap trade.”
The states
Kalshi told the D.C. Circuit in 2024 that “[t]he classic example is a contract on the outcome of a sporting event; as the legislative history directly confirms, Congress did not want sports betting to be conducted on derivatives markets.” The Ninth Circuit quoted that back and answered: “We agree.”
Field or conflict preemption — and do the circuits actually disagree?
The platforms & the CFTC
The Commodity Exchange Act is a comprehensive scheme, and section 2(a)(1)(A) expressly preempts state regulation of swaps traded on a designated contract market. Both circuits accept this.
The states
They accept it and it does not help, because it only bites if the contracts are swaps. The Ninth Circuit agreed with the Third on the framework and diverged one step earlier — which is why calling this a split about preemption misstates it.
Does the CFTC’s own view get deference?
The platforms & the CFTC
The Commission is the expert regulator, it registered these markets, and it appeared as amicus supporting the platforms. Its reading of its own statute should carry weight.
The states
After Loper Bright, it carries none. The Ninth Circuit said so directly: “We do not defer to the CFTC’s definition of gaming.” Courts decide what the statute means.
Who decides whether a listed contract is lawful, and when?
The platforms & the CFTC
A designated market self-certifies a new contract to the CFTC, which may review and disallow it. Until the Commission acts, the contract is lawfully listed and states cannot second-guess that federal judgement.
The states
Self-certification is not adjudication. A state enforcing its own gambling law is not attacking any CFTC action — the Ninth Circuit held Nevada was “pursuing enforcement of its own state law about what qualifies as a bet or wager, not what the CFTC considers a swap.”
What the Ninth Circuit left open
Judge Lee joined the majority in full, then wrote separately to flag the one thing it did not decide. He agreed with the textual analysis — that the “more natural reading of ‘event’” excludes a sporting result, since “[f]ew people would describe, say, the New York Mets’ latest loss of a game as an ‘event’” — and with the major-questions concern about reading abstract terms to upend “a multibillion-dollar industry historically regulated by states and Indian tribes” (Assad, slip op. 48–49).
Then: “One statutory provision, however, gives me pause.” Because the Special Rule says the Commission may determine that gaming contracts are contrary to the public interest, the statute “appears to give the CFTC discretion whether to ban altogether gaming contracts” and so “does not seem to categorically bar all gaming contracts, despite the text and contextual clues suggesting otherwise.” On that reading, “perhaps some unique sports events can be part of a swap trade if they meet the statutory requirements” (slip op. 49). The trailing condition carries the weight: the Special Rule alone would not foreclose a contract that independently satisfies the swap definition — which the majority held these contracts do not.
He declined to resolve it. “Ultimately, I do not think we need to resolve this thorny statutory interpretation question right now because 17 C.F.R. § 40.11 bars gaming contracts. While CFTC has proposed revising that regulation, it remains in the books and controls the outcome of this appeal” (slip op. 50). Neither side had pressed the point — Kalshi because the CFTC had already used the Special Rule to ban gaming contracts, Nevada because the provision “complicates the statutory analysis” (slip op. 49–50).
What it does and does not mean. One judge of three reads the statutory question underneath as genuinely unresolved, avoidable here only because of a regulation currently in flux. It does not unsettle the ruling. The Special Rule is the majority’s second, independent ground; the first — that sports event contracts are not “swaps” under 7 U.S.C. § 1a(47)(A)(ii) at all — carries no § 40.11 dependency, and it is that holding, not this one, that collides with Flaherty. As the majority put it, “[i]f these are not ‘gaming’ contracts, then the Special Rule has no relevance” (slip op. 37). Amending Reg. 40.11 would remove the alternative ground and leave the axis of the split standing.

Still undecided
Four more federal appeals could land before the Supreme Court acts, and any of them could deepen the split or narrow it.
Kalshi’s New York and Connecticut appeals and Coinbase’s Connecticut appeal (Nos. 26-1835, 26-2239 and 26-2297), heard in tandem. On November 3, 2026 one panel denied all three motions for an injunction pending appeal after argument, without reaching the merits, so neither state is barred from enforcing while the appeals run. Connecticut’s merits briefs are due November 20; New York filed its brief October 30. Undecided.
Maryland, argued May 7, 2026 and still undecided as of November 8. Kalshi has asked the panel to wait for the CFTC’s pending rules (the revised Rule 40.11 and the October 2026 swap-definition proposal) if it is uncertain. Kalshi lost below.
Three appeals from the Wisconsin order, consolidated; opening briefs were filed September 21, 2026, Wisconsin and the federal government filed their response briefs October 28, and replies are due November 19. Illinois appealed the October 30 preliminary injunction against it (No. 26-3266 in the federal government’s case), so the court now has both sides of an in-circuit split at the district level. Separately, on October 27 the court granted Kalshi permission to appeal the Ho-Chunk Nation’s IGRA ruling (No. 26-8020) and denied the Nation’s cross-petition.
Iowa: Kalshi appealed the September 8 denial of its injunction (No. 26-2874). On Kalshi’s motion its opening brief is now due December 7, 2026. The first time the question has reached this circuit; Novig, Crypto.com’s exchange and Kalshi have since sued Missouri, in the same circuit.
Utah: the only appeal from a final judgment (No. 26-4100). The court refused an injunction pending appeal on September 8, 2026; Kalshi filed its opening brief September 21, Utah answered, and on October 28 and 29 amicus briefs supporting Utah were filed, led by one from 37 states. The United States and the CFTC have since sued Utah in the district court, and Utah has filed criminal charges against Kalshi.
