Baltimore Sues Prediction Markets Over Sports Betting

The city of Baltimore initiated legal action against the prediction market platform Kalshi on March 12, 2024, alleging that the platform facilitated illegal sports betting and engaged in deceptive trade practices. The lawsuit, filed in the U.S. District Court for the District of Maryland, names Kalshi and its partners, including financial services firms Robinhood, Webull, and cryptocurrency exchange Coinbase, as defendants. Baltimore's legal team contends that Kalshi's operation of markets based on the outcomes of sporting events constitutes unlawful gambling under Maryland law, which strictly regulates sports wagering.

Central to the city's complaint is the assertion that Kalshi's prediction markets are not legitimate instruments for hedging or forecasting but rather a thinly veiled mechanism for sports betting. The lawsuit cites specific examples of Kalshi markets that allowed users to bet on the outcomes of professional sports games, including those involving the Baltimore Ravens and the Baltimore Orioles. The city argues that these activities bypass the state's regulated sports betting framework, which requires licensing and imposes taxes designed to benefit public services. By operating outside this framework, Kalshi and its partners are accused of depriving the city and the state of potential tax revenue and undermining consumer protection measures inherent in licensed operations.

The city's legal filing also highlights concerns about deceptive trade practices, alleging that Kalshi misrepresented the nature of its services to users and the public. Baltimore asserts that the platform's marketing and operational structure misled consumers into believing they were engaging in lawful speculative trading, rather than prohibited gambling. The lawsuit seeks injunctive relief to halt Kalshi's operations within the city and financial penalties for the alleged violations. The inclusion of Robinhood, Webull, and Coinbase as partners suggests that these entities may have provided services that facilitated Kalshi's operations, such as payment processing or user onboarding, thereby drawing them into the legal dispute.

Kalshi, which positions itself as a regulated exchange for event contracts, has previously stated its commitment to operating within legal boundaries. However, the city of Baltimore's lawsuit challenges this assertion, particularly concerning its application to sports-related events. The legal battle underscores the ongoing regulatory scrutiny faced by emerging financial platforms and the complex intersection of prediction markets, financial innovation, and existing gambling laws. The outcome of this case could have significant implications for the future operation of prediction markets, especially those that involve outcomes tied to sporting events, and may prompt further regulatory action or clarification from authorities across different jurisdictions.
