Maryland traders illegally wagered $1.1m on state election contracts

Maryland traders moved 1.1 million dollars through Kalshi and Polymarket on state election contracts while Maryland law prohibited them from doing so.

That number comes from Baltimore Sun reporting on trading activity tied to Maryland races during the current election cycle. The state has not licensed either platform. Neither platform appears to have geo-blocked Maryland users from accessing election contracts. The result is a live demonstration of exactly the enforcement problem that Senators Warren and Curtis raised in their letter to Kalshi CEO Tarek Mansour and Polymarket CEO Shayne Coplan — a letter that asked, among other things, what active safeguards the platforms maintain against legally prohibited participation.

The platforms' standard answer to state jurisdiction challenges is federal preemption: the Commodity Exchange Act gives the CFTC exclusive authority over designated contract markets, and state law cannot reach them. That argument is the spine of Kalshi's lawsuit against Missouri, filed after Attorney General Catherine Hanaway issued cease-and-desist letters and set an October 16 compliance deadline. It is the same argument running through Kalshi's suit against Louisiana. The theory is coherent. The problem is that it has not yet been settled by any federal court with binding authority over these states, which means the platforms are operating under a legal theory rather than a legal ruling.

Maryland is a different kind of exposure. The preemption argument addresses whether states can regulate the platforms. It does not address whether platforms have an independent obligation to screen out users from jurisdictions where participation is unlawful under state law. Those are separate questions, and the 1.1 million dollar figure suggests Kalshi and Polymarket have not treated them as urgent.

I want to flag my own tendency here. When I see a number like this attached to an unresolved legal question, I reach for the catastrophic read: mass enforcement, criminal referrals, platform shutdowns. Eleanor has been right to push back on that instinct. The more probable outcome is continued litigation, selective state enforcement, and gradual geo-blocking as courts force the issue platform by platform. The catastrophe scenario requires coordination among state attorneys general that the current record does not support.

But the Maryland data does something specific to the Warren-Curtis inquiry that I don't think the consensus has priced correctly. The senators asked what safeguards exist. The 1.1 million dollar answer from Maryland alone, in a state with an explicit ban, suggests the honest answer is: not enough to stop it. That response, delivered in writing before Tuesday's deadline, will be on the congressional record. Whatever the CFTC's eventual position on preemption, a written admission of inadequate controls in a Senate proceeding is a different kind of liability — one that survives the legal outcome either way.
