Robinhood takes prediction market battle to Supreme Court

Robinhood routes prediction market fight to Supreme Court as states tighten grip

When Robinhood moved its event contracts off Kalshi's rails and onto its own infrastructure, the operational question was straightforward enough. The legal question that followed is considerably less so, and now it sits at the highest address in American law.

Robinhood's petition to the Supreme Court arrives at a moment when the federal preemption argument has taken a beating in the lower courts. Judge Stephen Locher's Iowa ruling — his finding that the Commodity Exchange Act's text simply does not extend far enough to cover a Vikings game — is the clearest statement yet of where the state-law resistance is hardening. Locher's reasoning was precise: Congress would have had to say explicitly that it was displacing state gambling statutes, and it did not say that. The word "event" in the swap definition, he concluded, was written for interest rates and grain prices, not fourth-quarter scores. That reading will not bind other circuits, but it is coherent, and coherent adverse rulings accumulate.

Underdog's decision to surrender daily fantasy sports licences in seven states and file preemption suits in five others is a different kind of bet. Jeremy Levine is concentrating legal exposure rather than spreading it, which is either the disciplined move of someone who believes the constitutional argument wins, or the cornered move of someone who has run out of room to operate. I have watched companies make both versions of that call. The filing language — permanent injunction, Supremacy Clause, CFTC exclusive jurisdiction — is identical across all five complaints, which tells you this was built as a template to be argued once at altitude, not five times in state courtrooms.

The Illinois picture is the strangest. Travis Weaver's House Bill 5811 would repeal the exchange-wager tax and strip the definition that triggered it, but the Illinois legislature does not return until a veto session Weaver himself describes as the non-preferred timeline. He filed it now to create momentum before January. The tax is live, generating no revenue, and the state has already budgeted legal costs to defend it rather than receipts from it. That last detail is the one worth sitting with: Illinois allocated money to fight the tax in court before it knew whether the tax would collect anything. That is not fiscal policy — that is a position.

The consensus read is that the Supreme Court petition is a long shot, that SCOTUS takes a small fraction of the cases that reach it, and that the prediction market industry will spend another eighteen months grinding through circuit courts before there is clarity. I think that framing underweights how much the split between Locher's Iowa reasoning and the CFTC's own enforcement posture looks like exactly the kind of inter-branch conflict that interests the current court. The CFTC has argued, in Wisconsin and elsewhere, that its jurisdiction is exclusive. A federal judge in Iowa has now said that argument fails on the statutory text. That is not noise — it is the kind of doctrinal fracture that Supreme Court clerks flag.
