DOJ, CFTC Back Kalshi Against Arkansas Prediction Market Enforcement

The significance here is less about Arkansas than about the precedent: two federal agencies jointly asserting CFTC exclusivity signals that prediction markets are being framed as a federal jurisdiction question rather than a state gambling one. That matters for every platform offering event contracts, not just Kalshi, since state-by-state enforcement has been the main friction point. The open question is whether courts accept that preemption argument, because a ruling either way would shape how far state regulators can reach into federally regulated event contracts.
