Federal preemption

Quick definition. The legal doctrine under which federal law displaces state regulation. In PMs: whether CFTC's exclusive jurisdiction over swaps preempts state gaming law from regulating exchange-traded event contracts.

Key insights

The whole industry hinges on whether sports event contracts are "swaps" under section 1a of the Commodity Exchange Act. If yes, CFTC preempts state law and platforms operate in all 50 states. If no, platforms need 50-state gambling licenses (commercially fatal). · Hariharan.
The Third Circuit became the first appeals court to rule that sports event contracts are swaps, siding with Kalshi. But courts are split: Kalshi won in NJ (appeals), TN and N. Cal (district); states won in OH (district), MA and NV (state). The CFTC is suing Arizona, Illinois, and Connecticut on Kalshi's behalf. Washington state sued Kalshi; Robinhood (which uses Kalshi to power its PMs) counter-sued Washington.
19 federal lawsuits pending. Supreme Court resolution likely within two years.
The Dodd-Frank swap definition (section 1a) is: "Any agreement, contract, or transaction ... that provides for any purchase, sale, payment, or delivery (other than a dividend on an equity security) that is dependent on the occurrence, nonoccurrence, or the extent of the occurrence of an event or contingency associated with a potential financial, economic, or commercial consequence." The fight is over two phrases inside this definition.
Rob Schwartz (Morgan Lewis): under the CEA, "industry consensus is what matters." DCMs, FCMs, brokers, and DCOs all treat sports event contracts as swaps, so they qualify as swaps subject to CFTC's exclusive jurisdiction. He rebuts the trial-court line that the contracts "are sports wagers and everyone who sees them knows it" · the derivatives industry's own terminology disproves the "everyone knows" claim.
Park's timeline: the Feb 2026 jurisdictional standoff between CFTC Chairman Mike Selig and Utah Governor Cox is the canonical preemption moment. Park argues federal preemption under the CEA will hold against state AGs, citing Iowa Electronic Markets' 1988 no-action letter as the doctrinal anchor and Bitwise's PredictionShares ETF launch as the practical conclusion.
Jay Sykes (CRS): even if preemption holds, an insider-trading enforcement gap remains. SEC Rule 10b-5 and CFTC Rule 180.1 both require a breach of duty · many PM insiders (e.g., a candidate betting on his own race) don't owe one. Four pending congressional bills would close this gap.
The DFS parallel (Gouker): daily fantasy sports went through an identical state-by-state legal battle 2013-2015 before settling into a mostly-legal patchwork. The PM script may already be written, with federal-state compromise as the equilibrium.
Sykes also covers the CFTC's February 2026 advisory on two Kalshi enforcement actions · signaling that even with preemption, the CFTC intends to police certain conduct (insider trading) within the federal regime.
States retain authority over off-exchange sports betting (the actual sportsbooks like DraftKings/FanDuel). Preemption only covers exchange-traded event contracts. This split is crucial · it means Kalshi/Polymarket get federal cover while traditional sportsbooks stay state-regulated.
The DraftKings/FanDuel reaction (referenced in Eniola): the entry of Robinhood, DraftKings, Crypto.com, FanDuel into PMs is partly motivated by the preemption arbitrage · if event contracts are federally cleared, they can offer products their state licenses don't otherwise allow.
Tribal-gaming compacts add a third layer: some state opposition is driven by tribal exclusivity arrangements that PMs would erode.

In their words

The fate of the industry rests on a binary question of its own: do sports event contracts like 'who will win the Super Bowl' count as 'swaps'?· Shreyas Hariharan, *States vs. Prediction Markets*

Good luck building a venture-backed company if you need to get a gambling license in fifty states.· Shreyas Hariharan, *States vs. Prediction Markets*

All of these entities refer to and treat the contracts as 'swaps' … under the Commodity Exchange Act, industry consensus is what matters.· Rob Schwartz, *Federal Preemption in Sports Prediction Market Litigation*

[Sports event contracts] are sports wagers and everyone who sees them knows it.· trial-court characterization quoted (and rebutted) in Rob Schwartz, *Federal Preemption in Sports Prediction Market Litigation*

Where it matters

Federal preemption is the binary the industry needs answered to size its TAM. Without it, every venture-backed US PM is on an existential timer. For Dekant: building on Solana devnet (not yet mainnet, not yet US-regulated) keeps optionality · if preemption holds and Solana-based event contracts can be classified as swaps via a US-regulated wrapper (Kalshi-like clearing), the moat could open quickly.
