+
+Fourth Circuit oral argument framing as 'quacks like a duck' problem indicates courts are applying functional analysis (does it work like betting?) rather than formal/structural analysis (is it properly classified as a swap?). This functional approach makes tribal gaming concerns more salient because the court focuses on gambling-like characteristics rather than derivative classification.

 **Source:** Maryland Fourth Circuit Brief, Dodd-Frank Act (2010) Section 12(e)(2) revision
 
 Maryland's Fourth Circuit brief reveals that Dodd-Frank (2010) specifically deleted swaps from CEA Section 12(e)(2)'s state preemption provision. The statutory history shows Congress deliberately revised Section 12(e)(2) to exclude swaps from the preemption framework that covers commodity futures. Maryland argues: 'the current Section 12(e)(2) reflects a deliberate choice by Congress to preempt the application of state and local gaming laws to certain commodity futures but not to swaps.' This confirms that 'swaps' classification does NOT provide federal preemption protection for non-DCM platforms like MetaDAO. Congress intentionally chose this limit, and also cited 7 U.S.C. § 16(h) showing Congress knows how to preempt state law when it intends to—but chose not to for swaps.

+**Source:** Covers.com Fourth Circuit preview, May 7 2026
+
+Fourth Circuit's 'quacks like a duck' functional analysis approach suggests courts using functional tests are less receptive to structural/endogeneity defenses. If the court asks 'does it function like betting?' rather than 'is it structurally a bet on an external event?', MetaDAO's TWAP endogeneity argument may be insufficient without a functional distinction showing governance markets do NOT operate like gambling.

 **Source:** Bettors Insider circuit split synthesis, April-May 2026
 
 As of May 7, 2026, the circuit split has materialized with concrete timeline: Third Circuit ruled 2-1 pro-Kalshi (April 6), Ninth Circuit oral argument showed strong skepticism with all three Trump-appointed judges questioning swap classification and preemption (April 16), Fourth Circuit oral argument occurred May 7 with expected pro-state ruling by July-September 2026, and Sixth Circuit has intra-circuit split with ruling expected September-October 2026. Polymarket probability of SCOTUS cert acceptance by year-end 2026 is 64%. The multi-circuit split is now moving decisively toward 2-1 or 3-1 pro-state, making SCOTUS cert near-certain by mid-2027.

+Pre-argument analysis predicted Fourth Circuit will rule pro-state (anti-Kalshi), creating 2-1 circuit split with Third Circuit (pro-Kalshi), making SCOTUS cert 'near-certain' according to legal observers covering the oral argument.
