Louisiana Targets Five Prediction-Market Platforms
Louisiana is asking a state court to move quickly against Kalshi, Polymarket, Robinhood, Coinbase, and Gemini over contracts offered through prediction-market and related trading platforms. The state’s lawsuit seeks an immediate temporary restraining order and a broader injunction that would prevent the companies from offering the contracts at issue while the legal dispute continues.
In practical terms, Louisiana wants the named platforms to stop offering the contracts in the state before years of litigation conclude. Louisiana Attorney General Liz Murrill has emphasized that prediction markets could enable users to wager on a wide range of subjects, raising broader questions about how these products should be regulated under state gambling laws.
The defendants represent different parts of the financial and digital-asset markets. Kalshi and Polymarket operate dedicated prediction-market platforms, while Robinhood is a retail brokerage and Coinbase and Gemini are cryptocurrency exchanges. By naming all five companies in one action, Louisiana is treating them as participants in the same underlying activity regardless of how they characterize their businesses. The filing marks the first time Louisiana has consolidated its enforcement efforts against a broad group of prediction-market platforms in a single lawsuit.
Federal Preemption Drives the Legal Dispute
Kalshi filed a preemptive federal lawsuit on October 23, 2026, in the Western District of Louisiana. Polymarket has also filed a federal case. Both companies argue that the federal Commodity Exchange Act, which governs commodities and derivatives trading, preempts Louisiana law. They have also cited regulatory changes that have been in effect since August 2026 in support of their position.
The competing lawsuits have created a federal-versus-state jurisdictional fight. Kalshi and Polymarket went to federal court first to argue that Louisiana lacks authority over the contracts. Louisiana then pursued its own case to maintain that state gambling law applies. Kalshi is now seeking emergency relief to prevent state enforcement while the courts determine which legal framework controls.
As of November 12, 2026, no final ruling has resolved any of the cases filed in Louisiana. The legal questions, including whether federal law preempts state gambling statutes, remain contested.
Louisiana’s Gambling Enforcement Campaign
Louisiana’s current position follows action by the Louisiana Gaming Control Board in 2025, when the board issued an advisory stating that sports event contracts constitute gambling under state law. The state also strengthened its legal framework in 2026 through legislation expanding the definitions and penalties associated with unauthorized gambling activity.
Louisiana is not the only state pursuing enforcement against prediction-market platforms. Active enforcement actions involving similar platforms had been reported in at least 12 other states as of November 2026. Louisiana’s approach stands out because it has named five companies in a single filing rather than pursuing the platforms individually.
Potential Impact on Platforms and Users
The immediate operational risk is that Kalshi, Polymarket, Robinhood, Coinbase, and Gemini could be required to stop offering sports, awards, and election contracts to Louisiana users if the state obtains its requested restraining order or injunction. Any such restriction could remain in place while the broader litigation proceeds.
The inclusion of Coinbase and Gemini is also significant. Their presence alongside dedicated prediction-market operators suggests that states may not draw a meaningful legal distinction based solely on whether a company describes itself as a crypto exchange, brokerage, or prediction-market business.
The next developments to watch are the response to Kalshi’s emergency request, any decision on Louisiana’s request for a restraining order, and the parallel federal lawsuits filed by Kalshi and Polymarket. The outcome of those proceedings could determine whether the companies can continue offering the contracts in Louisiana.
Why This Matters
The central issue is federal preemption. If federal courts conclude that the Commodity Exchange Act governs these contracts, Louisiana’s gambling statutes—and potentially similar laws in the at least 12 other states taking action—could have limited reach. If the courts reject that argument, state regulators and attorneys general could gain significantly broader authority to restrict prediction-market contracts under state gambling laws.
The Louisiana cases therefore extend beyond the five named companies. They could help establish whether prediction-market products are primarily federally regulated derivatives, state-regulated gambling products, or activities subject to overlapping authority. No final ruling had settled that question as of November 12, 2026.
