Minnesota just passed the nation’s first outright ban, classing these markets as gambling and putting them under the state’s usual authority to police public morals and protect consumers.Washington didn’t wait long to weigh in. The federal Commodity Futures Trading Commission promptly sued, insisting that prediction markets are federally regulated financial instruments and that national commodities law overrides any conflicting state rules under the supremacy clause.

HOUSE MEASURE WOULD BAN LAWMAKERS AND STAFF FROM BETTING ON PREDICTION MARKET

Put the technical language aside and you end up with a question the country has wrestled with for a long time. When a state bars something under its reserved powers, and a federal regulator says it’s allowed under national authority, which side gets the last word?

This is the foundation for a fascinating debate with clear constitutional guidance that is often overlooked. The ‌federal ‌government ‌has settled into a dangerous habit: quote the part of the Constitution you like, skip the part that restrains you, and, if a conflict arises, assert Article 6 authority to declare federal rule “supreme.”

The supremacy clause in Article 6 of the U.S. Constitution has become Washington’s go-to cudgel. Agency regulators, Hill staff attorneys, and policy writers repeat the line with near-ritual certainty: federal law is supreme, states lose, case closed. Except that isn’t the Constitution. Not even close.
