Dodd-Frank drafter files amicus brief in New Jersey-Kalshi Supreme Court case
A former lawmaker and top financial regulator who helped craft the Dodd-Act's derivatives and swap-market policies filed an amicus brief in New Jersey's Supreme Court petition against Kalshi. The filing centers on how the Dodd-Act applies to the dispute. The state seeks review of a lower-court ruling that allowed Kalshi to offer sports event contracts under CFTC oversight. Multiple amici have now weighed in.
The brief gives state challengers the statute's own architecture against Kalshi's preemption defense. A Dodd-Frank co-architect framing the Act's swap and derivatives provisions as compatible with state gambling law carries weight justices may find harder to dismiss than state attorneys general alone. This deepens the intellectual pressure on Kalshi's federal shield just as the CFTC pursues its own swap-rule fix through the White House.
For Kalshi, every new amicus raises the cost of a clean federal victory and multiplies the arguments it must answer if cert is granted. Polymarket faces identical exposure in New York's parallel suit. The court's cert decision now turns partly on whether Dodd-Frank's authors saw state gambling power surviving alongside CFTC registration.
The amicus filings join a widening stack of Supreme Court petitions and regulatory maneuvers — including the CFTC's swap-rule bid to the White House, the NFL's own brief, and gaming-regulator backing for review — that together test whether federal preemption can survive the state-by-state assault on CFTC-registered event contracts.
