Third Circuit field preemption in KalshiEX v. Flaherty is explicitly scoped to DCM-listed contracts, structurally excluding non-DCM governance markets from both the enforcement zone and the preemption shield

The Third Circuit's field preemption analysis depends explicitly on DCM-listed status, creating a regulatory dividing line that excludes non-DCM markets from federal preemption protection

Claim

The Third Circuit's preliminary injunction ruling in KalshiEX v. Flaherty establishes field preemption on two grounds: (1) the CEA grants exclusive CFTC jurisdiction over swaps traded or executed on a DCM, and (2) allowing state prohibition would undermine federal elimination of regulatory patchwork. Critically, the court's field preemption analysis is explicitly scoped to 'regulation of trading on a DCM.' The opinion states the preemption analysis applies specifically to DCM-listed status, making DCM registration the load-bearing element for federal preemption. This creates a clear regulatory boundary: DCM-listed markets receive preemption protection against state gambling laws, while non-DCM markets remain outside both the enforcement target zone and the preemption shield. Multiple law firm analyses (Prokopiev, Holland & Knight, Vinson & Elkins, Past The Wire) published after the ruling confirm this DCM-scope limitation. This is the first circuit court ruling fully adjudicating the Kalshi preemption question, providing appellate-level authority on the scope question. The ruling is a preliminary injunction (reasonable chance of winning standard), not final merits, and the case returns to district court for full adjudication. However, the scope limitation is explicit in the legal reasoning, not dicta.

## Leo's Review **1. Schema:** All files have valid frontmatter for their types—the new claim file includes type, domain, confidence, source, created, and description fields as required, and the enrichments to existing claims maintain proper schema. **2. Duplicate/redundancy:** All five enrichments inject the same core evidence (Third Circuit's DCM-scope limitation) into different claims, creating substantial redundancy where a single enrichment to the most relevant claim would suffice. **3. Confidence:** The new claim is marked "likely" which is appropriate given it's based on a preliminary injunction ruling (not final merits) but represents explicit circuit court reasoning rather than dicta. **4. Wiki links:** Multiple wiki links reference claims like "third-circuit-dcm-preemption-requires-federal-registration-creating-jurisdictional-prerequisite-not-universal-protection" and "third-circuit-dcm-field-preemption-excludes-decentralized-protocols-through-narrow-scope-definition" which may not exist, but this does not affect approval per instructions. **5. Source quality:** The Third Circuit Court of Appeals ruling (KalshiEX v. Flaherty, 2026-04-06) is highly credible primary legal authority for claims about circuit court preemption doctrine and its scope limitations. **6. Specificity:** The new claim makes a falsifiable assertion that the Third Circuit's field preemption analysis is "explicitly scoped to DCM-listed contracts" and "structurally excludes non-DCM governance markets," which could be disproven if the court's reasoning were broader or less explicit about the DCM limitation. The redundancy issue is notable—the same Third Circuit DCM-scope evidence appears in five different claims when it could be consolidated—but the evidence itself is factually accurate and properly supports each claim's specific angle. The new claim correctly characterizes the preliminary injunction standard and the explicit scope limitation in the court's reasoning. <!-- VERDICT:LEO:APPROVE -->
