# Tribal sovereignty creates a third-dimension legal challenge to prediction market platforms that federal preemption doctrine does not resolve

60+ federally recognized tribes filed coordinated legal challenges arguing that CFTC-authorized prediction markets violate the Indian Gaming Regulatory Act (IGRA). The core argument is that when Congress amended the Commodity Exchange Act in 2010, it 'silently displaced decades of Indian gaming law without a single reference to tribes or IGRA' — an implied repeal that courts strongly disfavor. Blue Lake Rancheria filed actual lawsuits (not just amicus briefs) seeking declaratory judgments and injunctions against Kalshi. The tribes argue that gaming compacts grant them exclusive rights to certain gaming forms within states, and CFTC authorization circumvents these negotiated agreements. This creates a legal challenge structurally distinct from the state preemption cases because tribal sovereignty is constitutionally separate from state sovereignty. Federal preemption doctrine addresses federal-state conflicts, but tribal nations have a third legal status that doesn't fit neatly into that framework. Congressional representatives Jim Costa and Gabe Vasquez framed this as a tribal sovereignty issue, with Vasquez stating: 'Tribes in my district went through decades of negotiations only to see a federal agency allow prediction markets to bypass those longstanding requirements.' The remedies sought include geofencing requirements in states with tribal exclusivity agreements, which would functionally exclude prediction markets from significant portions of California, Oklahoma, Arizona, and New Mexico.
