The Alchemy Opinion
The 3rd Circuit just handed every company building under a federal license its most powerful weapon in over a decade. This goes far beyond prediction markets.
A Third Circuit judge logged onto Kalshi last fall and pulled up a Panthers-Buccaneers game. She could bet the winner. The point spread. Whether the two teams would combine for 45 or more points. Whether Mike Evans would score a touchdown. Then she wrote a dissent explaining that everything she saw was “virtually indistinguishable” from DraftKings. The majority agreed with her description of the product. And it ruled for Kalshi anyway.
The gap between what a product looks like to a user and what the law calls it is now the most important question in financial regulation. And if you build anything that sits under a federal license, you need to understand why.
TLDR
The Thesis: Everyone is covering the Third Circuit’s Kalshi v. Flaherty opinion as a prediction markets case. It is a federal preemption landmark that will reshape the regulatory strategy of every company building products under federal jurisdiction, from stablecoins to perps markets to AI.
The Framework: The court adopted the “narrow framing” of preemption. The relevant field is trading on a federally licensed exchange, not gambling broadly. The CEA occupies that field, and states cannot regulate within it.
The Takeaway: If you are building a regulated financial product and have a path to a federal license, this opinion is Exhibit A in your state-regulatory strategy. Call your lawyer. Today.
1. Swaps Are Swaps
Judge Porter (Trump appointee), writing for a 2-1 majority joined by Chief Judge Chagares (Bush appointee), affirmed the district court’s preliminary injunction blocking New Jersey from enforcing its state gambling laws against Kalshi’s sports-event contracts. The holding: the Commodity Exchange Act preempts state law when it comes to swaps traded on CFTC-licensed Designated Contract Markets. Both field preemption and conflict preemption apply. Swaps are swaps. This is the first federal appellate court to rule on the question. Bloomberg Law called it “a novel ruling” on “the widespread legal battle” between prediction markets and states. They’re right about the first part. They’re underselling the second.
The reasoning is clean and text-driven. The CEA grants the CFTC “exclusive jurisdiction” over swaps traded on DCMs. Kalshi’s event contracts fit the statutory definition of swaps. Kalshi operates a CFTC-licensed DCM. State gambling regulators cannot reach into the exchange to ban those contracts.
The key analytical move: New Jersey framed the issue broadly (NJ regulates gambling). The Third Circuit framed it narrowly (you are trying to regulate trading on a federal exchange). Porter wrote that New Jersey’s broad framing was the wrong lens: “The text of the Act suggests that the narrow framing is the better reading.” Lawyers will cite that sentence in preemption briefs for years.
The majority also went belt-and-suspenders, holding that conflict preemption bars New Jersey’s enforcement on independent grounds. Fifty different state regimes for licensing, age limits, permissible contracts, and liquidity standards would, the court concluded, “grind a national DCM to a halt.” Congress did not want that.
Strategic takeaway: The majority opinion is disciplined about scope. It does not hold that the CEA preempts all state gambling regulation. It holds that the CEA preempts state laws that “directly interfere with swaps traded on DCMs.” That precision is what makes the opinion durable and useful beyond prediction markets.
2. The Alchemy Defense
Judge Roth (GHW Bush appointee) wrote the dissent. She calls Kalshi’s DCM registration and contract branding “acts of alchemy that transmute its products from sports gambling to futures trading.” Her Panthers-Bucs diligence is the most vivid passage in the opinion: game outcomes, point spreads, game props, player props. She did her own underwriting on the product. She concluded it was gambling. The majority said the label matters more than the look.
Kalshi told the DC Circuit in its earlier election-markets case that “Congress did not want sports betting to be conducted on derivatives markets.” Now Kalshi argues the opposite. Judge Abelson in Maryland caught the same contradiction, asking Kalshi’s lawyers point-blank: “Why did Kalshi say the opposite to the DC Circuit?” That inconsistency will feature in any cert petition.
The broader point here deserves attention. As the foremost legal commentator on this litigation, Andrew Wallach, put it in Forbes: “When Congress wants to address sports gambling, it barges in through the front door.” The Wire Act. PASPA. Congress has never been subtle about gambling policy. The idea that Congress silently approved nationwide sports betting through a broad swap definition in Dodd-Frank, while PASPA was still in effect, strains credulity.
But the majority’s response is: the statute says what it says. Congress defined “swap” broadly. The CFTC has exclusive jurisdiction over DCM-traded swaps. If Congress does not like the result, Congress can change the law. Two bills are pending to do exactly that: the “Prediction Markets Are Gambling Act” (Sens. Curtis and Schiff) and a companion bill from Sens. Blumenthal and Kim that would ban insider trading, restrict users under 21, and preserve state oversight.
Founder takeaway: The dissent’s frustration is the point. The majority is saying that the label you operate under, the federal license you hold, and the statutory framework you fit within determine who regulates you. The substance of what your users experience is, for preemption purposes, beside the point. If you are on the right side of a federal registration, that is a powerful tool.
3. Twenty Lawsuits and a Criminal Indictment
This opinion does not land in a vacuum. Consider the last ten days alone:
April 2: The Trump administration, through the CFTC and DOJ, sued Illinois, Connecticut, and Arizona, arguing that the CFTC has exclusive jurisdiction over event contracts. CFTC Chairman Mike Selig accused the states of trying to impose “a fragmented patchwork of state regulations.” The same day, Senators Blumenthal and Kim introduced legislation to make clear that prediction markets are not exempt from state oversight.
April 4: A Nevada state judge extended a ban on Kalshi, calling its baseball contracts “indistinguishable” from placing a bet on a state gaming platform. In Arizona, a federal judge heard arguments on Kalshi’s motion to halt the state’s criminal prosecution. (Arizona filed 20 misdemeanor counts against Kalshi in March, the first criminal charges ever brought against a prediction market.)
April 6: The Third Circuit rules for Kalshi. The first circuit-level win for the platform.
Ohio’s Chief Judge Morrison ruled against Kalshi in March, writing that treating sports-event contracts as swaps was absurd: “Currency exchange rates, the weather, and energy costs all [affect commodity prices]; the number of points scored in the Huskies-Bobcats game does not.” TD Cowen has said the states still appear to hold the stronger overall legal position, with resolution not arriving until 2028.
The next procedural move: New Jersey can petition for rehearing en banc before the full Third Circuit. A 2-1 split on a question this consequential, with a sharp dissent and a multi-circuit conflict already developing, makes en banc review a real possibility. If the full court takes it up, the panel opinion gets vacated and the Third Circuit rehears the case. If not, the path runs to the Supreme Court.
The Third Circuit ruled for Kalshi. The Maryland district court (Fourth Circuit) ruled against Kalshi and is on appeal. The Sixth Circuit has Tennessee (pro-Kalshi) and Ohio (anti-Kalshi) headed to the same court. The Ninth Circuit is weighing Nevada. Four circuits are now evaluating the same statutory text and reaching opposite conclusions.
Lawyer takeaway: Read the Third Circuit opinion alongside the Maryland opinion. They reach opposite conclusions on the same text using the same framework. The Third Circuit says the “presumption against preemption” does not apply because the relevant field is DCM trading, not gambling. Maryland says it does apply because Congress did not manifest a “clear and manifest purpose” to displace state gambling authority. That disagreement is the entire case at the Supreme Court.
4. The Preemption Blueprint
Everyone covering this story is focused on whether you can bet on the NFL through Kalshi. Fine. The preemption logic in this opinion reaches further than that. It applies to any product that sits at the intersection of a federal regulatory framework and overlapping state regulation.
Stablecoins and payments. The GENIUS Act, if passed, would create a federal licensing framework for stablecoin issuers. Whether that framework preempts state money transmission laws and New York’s BitLicense is an open question. The Third Circuit’s reasoning, that a federal license for a specific type of activity preempts state laws regulating that same activity on the licensed platform, seems to transfer over.
Perps and DeFi derivatives. If a protocol or its front-end operator obtains federal registration (or a no-action position) for derivative products, does that preempt state-level enforcement under state securities or gambling laws? The Third Circuit says the answer depends on whether the products trade on a federally supervised market. That is the exact question the perps market will face.
AI products and defense tech. Multiple states are passing AI regulation bills and regulation around drones and other defense tech. If Congress passes a federal AI framework with a preemption clause (or even without one, if it is sufficiently comprehensive), the Kalshi opinion becomes the template for arguing that state AI regulations cannot reach products operating under federal oversight.
The CFTC is pushing this broader principle right now. Its lawsuits against three states and Chairman Selig’s public posture (”We will see you in court”) signal that the federal government wants exclusive jurisdiction over DCM-traded products and will fight for it. The OCC took the same stance with fintech charters. The SEC takes it with nationally registered securities exchanges. The Kalshi opinion now gives that argument circuit-level backing.
Investor takeaway: The companies with the strongest regulatory moats going forward will be the ones that secured federal licenses or registrations early. If you are evaluating a deal and the company has a path to federal registration that would trigger preemption of state regulation, that path just got wider.
What to Do This Week
Read the opinion. All of it. The majority is tight and well-organized. The dissent is excellent adversarial briefing. Together they map the entire analytical terrain.
If you are building a product that could fit within a federal regulatory framework, talk to your lawyer about whether a federal registration or license could preempt state-level regulatory friction. The Third Circuit gave that conversation a new anchor.
If you are advising a company with state regulatory exposure, map the Kalshi preemption framework onto your client’s situation. The majority’s “narrow framing” principle, defining the preempted field as the specific federally licensed activity rather than the broader category of state regulation, is the analytical move to study.
If you are a state regulator, you now have a circuit-level appellate opinion going against you, an executive branch suing states on the same theory, and a cert petition on the horizon. Your enforcement window shrinks with every filing.
Watch the Fourth Circuit. If it rules opposite to the Third on the Maryland appeal, the Supreme Court path accelerates. If it agrees, the states’ position collapses across the eastern seaboard.
The dissent called it alchemy. The majority called it statutory interpretation. The Supreme Court will call it next, unless a fractured Congress passes new law first.
