# The Prediction Market Act of 2026's event contract definition structurally excludes decentralized governance markets through DCM/SEF listing requirement

The Prediction Market Act of 2026 defines 'event contract' as a contract 'listed by a designated contract market or swap execution facility.' This is a structural scope limitation, not a functional test. MetaDAO's conditional governance markets operate on decentralized infrastructure without DCM or SEF registration, placing them outside the Act's definitional reach. This creates a parallel defense to the TWAP endogeneity argument: even if MetaDAO's markets were considered to predict 'external' events, they would still fall outside the Act's scope because they are not DCM/SEF-listed. The protection is structural but fragile—if future amendments or rulemaking expand scope to 'any platform' or create a new registration category for decentralized venues, this safe harbor disappears. The bill's competing alternative (Curtis-Schiff Prediction Markets Are Gambling Act) would prohibit sports/casino contracts on CFTC platforms entirely, showing fundamental legislative disagreement on prediction market philosophy.


## Supporting Evidence

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

Third Circuit ruling independently converges on DCM registration as the regulatory boundary for prediction market preemption, matching the Prediction Market Act's DCM/SEF scope limitation. Two independent legal sources (judicial and legislative) now agree that DCM listing is load-bearing for regulatory coverage.
