Baltimore has filed lawsuits against prediction market platforms Kalshi and Polymarket, accusing them of running unlicensed sports betting operations. The legal action, if successful, could force these platforms to comply with state gambling laws across the country.
The Allegations
The city's lawsuits claim that Kalshi and Polymarket are effectively taking bets on sports events without the required licenses. Baltimore argues that the platforms' offerings—which let users wager on outcomes like game results or player performances—fall squarely under state gambling regulations. By sidestepping those rules, the city says, the companies are operating outside the law.
Neither platform has publicly responded to the lawsuits as of this writing. The cases are in their early stages, and no court dates have been set.
Prediction markets have grown rapidly in recent years, letting people bet on everything from election results to weather patterns. But sports betting is a different animal. Most states have strict licensing regimes for sports wagering, often tied to casinos or racetracks. If Baltimore's lawsuits succeed, they could set a precedent that forces prediction platforms to obtain those same licenses—or stop offering sports-related contracts altogether.
The stakes are high. A ruling against Kalshi or Polymarket could ripple through the entire industry, making it harder for any platform to offer sports-based predictions without state approval. That would be a major shift for companies that have operated in a regulatory gray area, treating their products as financial derivatives rather than gambling.
State Compliance Burdens
The potential fallout goes beyond just these two companies. If courts side with Baltimore, prediction markets might have to navigate a patchwork of state gambling laws, each with its own licensing fees, reporting requirements, and tax obligations. That could mean significant compliance costs for platforms that currently operate with minimal oversight.
For smaller players in the space, the burden could be prohibitive. Some might choose to exit the sports betting market entirely rather than deal with the regulatory maze. Others could try to restructure their offerings to avoid triggering state gambling statutes, though that's easier said than done.
Baltimore's move also signals that local governments are paying attention to these platforms. The city isn't just concerned about its own residents—it's taking a stand that could influence how other municipalities and states approach the issue.
What's at Stake
The lawsuits raise a fundamental question: are prediction markets a form of gambling, or something else? The answer will determine how they're regulated. If they're treated like sportsbooks, they'll need licenses in every state where they operate. If they're seen as financial products, they might fall under different rules entirely.
For now, the platforms continue to operate as they always have. But the legal challenge from Baltimore could change that. The city is asking the courts to draw a line, and the outcome will likely shape the industry for years to come.
No hearing has been scheduled yet, and it's unclear how long the cases will take to resolve. What is clear is that Baltimore isn't backing down—and the prediction market industry is watching closely.
