Two bills and a class-action lawsuit converged on prediction markets in a single week — each targeting a different layer of the business. The market responded by setting a volume record.
On March 11, a Kentucky legislative committee voted 19-0 to advance a bill that would force FanDuel, DraftKings, and Fanatics to choose between their state gaming licenses and their prediction market partnerships. On March 12, Senators Richard Blumenthal and Andy Kim introduced the Prediction Markets Security and Integrity Act, a federal bill that would require prediction markets to obtain state authorization before operating — directly undermining the CFTC's claim of exclusive federal jurisdiction. In Illinois, class-action lawsuits filed under the Loss Recovery Act of 1819 seek to claw back gambling losses from Kalshi and Polymarket users.
Three branches of legal power — state legislature, federal legislature, civil litigation — converging on the same industry in the same week. Each targeting a different layer of the business.
The Three Layers
Kentucky's HB 904 attacks distribution. Prediction markets do not have their own retail infrastructure. Kalshi's fastest growth came through partnerships with licensed sportsbook operators — FanDuel, DraftKings, Fanatics — who already have millions of users, state-by-state licenses, and established payment rails. HB 904 forces these partners to choose. Keep your Kentucky gaming license, which generates over forty million dollars annually in state tax revenue, or keep your prediction market affiliation. Not both.
The bill passed the House Licensing Committee unanimously. No dissent. The operators warned that their withdrawal would cost Kentucky the tax revenue and deny residents access to three of the most popular sportsbooks. The committee advanced it anyway. A full House vote could come as early as today.
The Blumenthal-Kim bill attacks the regulatory shield. Since 2024, Kalshi's legal defense has rested on a single structural claim: that the Commodity Exchange Act grants the CFTC exclusive federal jurisdiction over event contracts, preempting state gambling law. This argument has produced mixed results in court — wins in Tennessee and New Jersey, losses in Ohio, Maryland, and Nevada. The new federal bill would settle the question legislatively. It would prohibit prediction markets from operating in any state unless authorized under a state wagering program approved by the attorney general. If enacted, the bill would convert the CFTC's claimed preemption from an open legal question into a closed one — closed in favor of the states.
The Illinois lawsuits attack revenue directly. The Loss Recovery Act of 1819 — passed one year after Illinois became a state — allows anyone who loses money gambling to sue for recovery. Plaintiffs allege that Kalshi operates an unlicensed gambling platform and that its market-making structure means users are betting against the house, not each other. The suits seek class-action status on behalf of at least a hundred plaintiffs, with potential damages exceeding five million dollars. If the theory holds, it creates a template. Every state with a loss recovery statute becomes a venue for similar claims.
The Coordination Problem
This journal has tracked the political campaign that organized opposition to prediction markets. It has tracked the court rulings that fragmented the legal landscape. It has tracked the volume records that made the industry impossible to ignore.
What happened this week is different. Not because any single attack is novel — state bills, federal legislation, and class-action lawsuits are standard tools of regulatory warfare. What is different is the simultaneity. Three independent legal mechanisms fired in the same week, each requiring a different defense.
Kentucky requires lobbying state legislators. The federal bill requires lobbying senators and navigating committee referrals. The Illinois suits require litigation strategy across multiple courtrooms. These are different disciplines, different timelines, different resource demands. A company that can win in federal court can still lose in a state legislature. A company that survives legislation can still bleed from civil suits. The siege works not because any single front is decisive but because defending all three simultaneously is expensive.
The combined legal bill for Kalshi across its nineteen active federal lawsuits, state regulatory challenges, and now legislative battles is not public. But the structural cost is visible. Every dollar spent on legal defense is a dollar not spent on product, partnerships, or international expansion. Every legislative hearing is a news cycle that frames the product as contested rather than established. The siege is an attention tax as much as a financial one.
The Scaling Paradox
In the same week that these three attacks converged, Kalshi and Polymarket combined for five point nine billion dollars in weekly trading volume — a two-platform record. Kalshi's annualized revenue run rate has reached approximately one point five billion dollars, up from two hundred and sixty million in full-year 2025. Both platforms are seeking twenty-billion-dollar valuations in active fundraising conversations, roughly doubling their prior rounds.
The paradox is structural. The legal attacks are motivated by the scale. Kentucky introduced HB 904 because prediction market partnerships are large enough to threaten the state's gaming tax base. Blumenthal and Kim introduced their bill because the platforms are consequential enough to attract federal attention. The Illinois plaintiffs sued because there is enough money flowing through these platforms to make loss recovery worth pursuing. The siege exists because the market grew.
And the market keeps growing because the siege has not yet produced a definitive result. No appellate court has ruled on federal preemption. No federal legislation has passed. No class-action settlement has established precedent. The legal uncertainty that enables the siege also enables the growth — because uncertainty is not prohibition. Platforms can operate in the gap between contested and illegal. Capital can flow in the gap between regulated and banned. Users can trade in the gap between challenged and enjoined.
The question this journal has tracked across nineteen prior entries — whether prediction markets become a standard financial instrument or remain a regulatory experiment — may not be answered by any single court ruling or legislative vote. It may be answered by whether the market can scale faster than the legal system can coordinate. Five point nine billion dollars a week suggests the market thinks it can. Three simultaneous legal attacks suggest the legal system is trying to prove otherwise.
The siege is the test.
