# CFTC preemption defense explicitly excludes unregistered prediction market platforms from federal protection

The CFTC's Massachusetts SJC amicus brief exclusively addresses 'CFTC-regulated markets' and 'CFTC-regulated prediction markets.' Chairman Selig's statement emphasizes 'the sole authority to regulate commodity derivatives markets, including prediction markets' but the brief's scope is limited to platforms under CFTC jurisdiction. The Agent Notes highlight: 'Any reference to on-chain or blockchain-based platforms' is absent. 'CFTC's brief is EXCLUSIVELY about CFTC-regulated exchanges. Non-registered on-chain platforms like MetaDAO have no federal patron at the Massachusetts SJC, the 9th Circuit, or anywhere else.' This creates a two-tier regulatory structure: DCM-registered platforms get federal preemption defense in both federal and state courts, while unregistered platforms (including futarchy-governed DAOs) face state gambling enforcement without federal protection. This is consistent with the CFTC's institutional incentive to defend its regulatory perimeter while not extending protection to platforms outside its jurisdiction.


## Supporting Evidence

**Source:** Arizona District Court TRO, April 10, 2026

Arizona TRO explicitly limited to 'CFTC-regulated DCMs' with court reasoning premised on CEA exclusive jurisdiction over 'federally registered' derivatives platforms. No extension to non-registered on-chain protocols. Court's reasoning makes the two-tier structure MORE explicit by predicating preemption on federal registration status.


## Supporting Evidence

**Source:** CFTC Wisconsin filing April 28, 2026

CFTC's Wisconsin lawsuit (April 28, 2026) defends Kalshi and Polymarket—both DCM-registered platforms. The federal preemption argument explicitly relies on Congress giving CFTC exclusive jurisdiction over derivatives traded on registered exchanges. Unregistered platforms remain outside the preemption scope.


## Supporting Evidence

**Source:** CoinDesk/CFTC Press Release, April 28, 2026

Wisconsin lawsuit (April 28, 2026) is the 5th state in CFTC's enforcement campaign, targeting only DCM-registered platforms (Coinbase, Crypto.com, Kalshi, Polymarket, Robinhood). Pattern now spans 5 states over 26 days with zero enforcement against unregistered decentralized platforms.


## Supporting Evidence

**Source:** CoinDesk Policy, CFTC SDNY filing April 24 2026

CFTC's New York lawsuit scope explicitly limited to 'CFTC registrants' and 'federally regulated exchanges' with no protection asserted for non-registered on-chain protocols. The complaint's legal theory relies on DCM registration as the trigger for federal preemption.


## Supporting Evidence

**Source:** CoinDesk/Bloomberg, April 28, 2026

Polymarket's strategy confirms that DCM registration is the gateway to CFTC preemption protection. The 2022 settlement banned US users from the unregistered main exchange. The November 2025 QCEX acquisition created a registered DCM for limited contracts. Now Polymarket seeks to extend DCM coverage to the main exchange through an 'Amended Order of Designation'—demonstrating that preemption protection requires formal DCM registration, not just CFTC settlement.


## Challenging Evidence

**Source:** Bettors Insider / Boston Globe, May 1, 2026

The Statute of Anne class action (Smith v. Kalshi, May 1, 2026) introduces a damages liability track that operates independently of CFTC preemption victory. Even if Kalshi wins the federal preemption argument, the Statute of Anne theory allows plaintiffs to recover losses from the period when Kalshi operated without state compliance. This creates historical liability exposure that cannot be eliminated by winning the jurisdictional case going forward.


## Supporting Evidence

**Source:** Bank of America report via CoinDesk, April 9, 2026

Kalshi's 89% US market share versus Polymarket's 7% demonstrates the practical effect of DCM preemption scope exclusion. Polymarket remains restricted from US users due to 2022 CFTC settlement, while Kalshi's DCM status gives it near-monopoly access to the regulated US market. The 89/7/4 split is the empirical outcome of DCM-only preemption protection.


## Extending Evidence

**Source:** Third Circuit ruling analysis, Massachusetts SJC pre-argument record

Third Circuit's April 6, 2026 ruling creates first federal appellate precedent for CFTC preemption, establishing that CEA preempts state gaming laws for contracts on registered DCM platforms. However, the ruling's 'swaps' definition under CEA Section 1a(47) may create a second track for federal protection: contracts with payment dependent on financial/economic contingencies could qualify as federally-protected swaps regardless of DCM registration. This creates potential dual-path protection for prediction markets: DCM registration (centralized platforms) or swap classification (potentially decentralized protocols with endogenous settlement).


## Supporting Evidence

**Source:** Gambling911, May 4, 2026

Second independent source confirms Massachusetts SJC skepticism of Kalshi's federal preemption argument. Gambling911 reports court appeared inclined to allow state regulation of sports gambling in online prediction markets despite CFTC's claim of exclusive authority, corroborating Bloomberg's May 4 report of the same oral argument.


## Extending Evidence

**Source:** ZwillGen, May 4 2026

ZwillGen's framework distinguishes between 'partial preemption (sports event contracts)' which Kalshi is arguing versus 'broad field preemption of all gambling' — this is 'harder to win' under the 'clear Congressional intent' standard. The analysis confirms that DCM preemption arguments are contract-type specific rather than platform-wide, making unregistered platforms categorically outside the preemption shield.


## Supporting Evidence

**Source:** Finance Magnates, May 5, 2026

Nearly 40 state AGs oppose Kalshi's federal preemption position across party lines, arguing products functioning as bets must comply with state gambling licensing and taxation requirements. New York's gambling tax rate is 51%. If Kalshi loses, states gain legal template for state-by-state compliance requirements that would price out smaller platforms. Case expected to reach US Supreme Court.


## Supporting Evidence

**Source:** Holland & Knight, Third Circuit KalshiEX v. Flaherty analysis (April 7, 2026)

Holland & Knight provides the direct judicial quote establishing DCM registration as the preemption threshold: 'Without federal registration as a designated contract market, the preemption framework would not apply.' The court defined the preempted field as 'regulation of trading on a DCM' and stated that Kalshi operates 'a registered DCM under the exclusive jurisdiction of the CFTC.' This is explicit confirmation that preemption is registration-dependent, not category-dependent.


## Extending Evidence

**Source:** ZwillGen post-SJC analysis, May 2026

ZwillGen identifies timing as determinative: 'The question of who sues first may be a determinative one.' When prediction market platforms initiate federal court cases, they control the preemption narrative. When state regulators file first in state court, the framing shifts to gambling regulation enforcement, favoring state authority. This creates a procedural race independent of doctrinal preemption strength.


## Extending Evidence

**Source:** ZwillGen post-SJC analysis, May 2026

Forum selection shapes appellate path: Massachusetts' state court venue restricted Kalshi's ability to quickly reach sympathetic federal appellate courts. After removal to federal court failed, the case remained in Suffolk County Superior Court, where appeals go through state courts rather than the federal circuit system. State courts apply a presumption against preemption that federal courts do not.


## Supporting Evidence

**Source:** CFTC Press Release 9218-26, CoinDesk April 24 2026

CFTC's offensive suits seek permanent injunctions preventing states from enforcing gambling laws against 'CFTC registrants' specifically. Non-DCM operators have no standing to benefit from these declaratory judgments, operationalizing the registration prerequisite for federal protection.


## Supporting Evidence

**Source:** Norton Rose Fulbright, April 30, 2026

Norton Rose's preemption analysis confirms the CFTC's argument rests on field preemption + conflict preemption under CEA for CFTC-regulated DCMs. The 9th Circuit majority held CFTC has exclusive jurisdiction for CFTC-registered DCMs using a regulatory status test. This explicitly confirms preemption protection requires DCM registration, leaving unregistered on-chain protocols outside the preemption shield.


## Supporting Evidence

**Source:** Law.com / National Law Journal, Fourth Circuit oral argument coverage, May 7, 2026

Fourth Circuit oral argument featured Judge Gregory's 'basically gambling' characterization of sports event contracts, while simultaneously pressing Maryland's counsel on whether DCMs fall outside statutory swap definitions. Law.com described the argument as 'anything but a slam dunk for Kalshi' but also 'not a clear pro-Maryland outcome,' suggesting the panel is wrestling with the preemption scope question rather than rejecting it outright.


## Extending Evidence

**Source:** InGame Fourth Circuit oral argument coverage, May 8 2026

Fourth Circuit panel showed genuine openness to field preemption arguments despite expressing concerns about sports contracts being gambling-like. Judge Gregory stated 'It seems like the whole point is that they wanted it to be a field preemption' and predicted 'this will probably end up with the Supreme Court.' This contrasts with the expected pro-state outcome and suggests field preemption doctrine may be more robust than conflict preemption analysis across circuits.


## Supporting Evidence

**Source:** Third Circuit KalshiEX v. Flaherty (2026-04-06)

Third Circuit field preemption analysis explicitly depends on DCM-listed status, with the court stating preemption applies specifically to 'regulation of trading on a DCM.' This provides circuit court authority for the two-tier regulatory architecture where DCM registration is the prerequisite for preemption protection.


## Supporting Evidence

**Source:** DefiRate Fourth Circuit oral argument analysis, May 8, 2026

Fourth Circuit panel's focus on Kalshi's DCM registration status and Rule 40.11 compliance (Judge Benjamin questioning 'how the plain language of Rule 40.11 works given Kalshi's self-certification') reinforces that preemption arguments are DCM-specific. Maryland's argument that sports event contracts 'don't fit the statutory swaps definition and remain subject to state regulation' was received favorably by panel, suggesting DCM registration is necessary but not sufficient for preemption.
