Baltimore Takes Legal Action Against Kalshi and Polymarket Over Unlicensed Betting Practices

Baltimore's recent legal move against prediction-market platforms Kalshi and Polymarket highlights a growing concern over unregulated sports betting operations disguised as legitimate financial instruments. The city has lodged separate lawsuits claiming both companies are running illegal sportsbooks while misleading customers regarding the legality of their products.

Baltimore's Legal Action: Context and Motive

On August 13, Baltimore Mayor Brandon M. Scott and the City Council initiated legal actions in the Baltimore City Circuit Court. These complaints assert violations of the city's Consumer Protection Ordinance, emphasizing that these platforms lack the necessary Maryland sports betting licenses. The backdrop to this legal maneuvering is a rapidly changing landscape in which prediction markets, which operate on the premise of betting on future events, have increasingly captured public interest. With sports betting becoming legalized in many places, companies have been eager to find ways to offer similar products without falling under traditional gambling regulations.

Predictive markets claim to enable users to bet on outcomes in various domains, including politics and sports, often marketed as a sophisticated investment opportunity. But these offerings frequently mimic traditional sports wagering in practice. Here’s the thing: while the city unequivocally runs the risk of stifling innovation, it also has a responsibility to protect its constituents from potential exploitation and financial mismanagement.

Details of the Lawsuits

The lawsuit against Polymarket identifies associated entities including QCX LLC, Blockratize Inc., and QC Tech LLC, while the Kalshi complaint also mentions Robinhood, Webull, and Coinbase as facilitators for Baltimore residents accessing the prediction market contracts. This raises an important point: if these platforms can lure users through familiar financial interfaces, what responsibilities do these financial institutions have in safeguarding against potential harm?

Allegations Against Prediction Markets

The lawsuits contend that while Kalshi refers to its offerings as “prediction markets,” they undoubtedly constitute “sports wagering” under Maryland law. The same accusation is leveled against Polymarket's operations. Customers can place bets on a variety of outcomes, including game results and proposition bets, which falls under the purview of licensed sports wagering that these platforms fail to provide. Like many potential illegal operators, they may be banking on ambiguous legal definitions to maintain operations.

“These companies are running sportsbooks without licenses and betting that a new label will put them above the law,” stated Mayor Scott. “It won’t. Baltimore will not let multibillion-dollar companies put profits over people and harm our communities through illegal gambling.” This message highlights growing frustration among lawmakers with companies attempting to exploit regulatory gray areas. But does this aggressive stance, while commendable, push necessary innovations underground instead of into the light where they can be monitored and regulated?

Consumer Risks and Market Analysis

In addition to consumer protection issues, Baltimore's legal action raises serious concerns about the risks imposed on users, which regulation typically aims to mitigate. The Polymarket complaint alleges that daily traders might face off against sophisticated participants wielding advanced technology and proprietary information, creating an inherently uneven playing field. As with other highly speculative environments, the potential for manipulation and insider trading looms large.

The legal filings argue that Polymarket misleads consumers regarding risks associated with its products, with more than 70% of trading gains in the hands of the top 0.04% of users. The Kalshi complaint asserts that a large percentage of bettors lose their stakes, with losses outnumbering profits nearly three to one. This points to an environment where the majority of users are at a severe disadvantage. And while those at the top may enjoy success, for most, betting remains a losing proposition. If you're working in this space, this reality should raise red flags regarding the viability and ethics of participating.

This scrutiny isn’t new; Maryland regulators previously issued cease-and-desist letters to Kalshi, asserting that its sports contracts equate to illegal wagers. The Maryland Lottery and Gaming Control Agency reiterated in November 2025 that such contracts lacking a valid sports wagering license constitute unlawful activity within the state.

Legal Ramifications and Consumer Protections

City Solicitor Ebony M. Thompson emphasized that, "Kalshi and Polymarket cannot circumvent Baltimore’s consumer protections by repackaging gambling as something else or claiming federal regulation puts them beyond the reach of our laws.” The city seeks civil penalties, restitution, and injunctions against unauthorized sports betting, with up to $1,000 sought for each ordinance violation. It’s a strong message aimed at companies that might assume they can operate without oversight simply by adopting new terminology or frameworks.

Adam Levitt, a founding partner at DiCello Levitt, articulated the broader implications of this legal action: "Allowing prediction market companies to evade gambling laws would set a dangerous precedent far beyond Baltimore.” These actions indicate a firm stance against perceived attempts to bypass consumer protections and uphold regulatory standards in the betting industry. The fallout from these lawsuits may ripple into other jurisdictions, prompting further scrutiny of similar operations at both state and federal levels.

Implications for the Future of Prediction Markets

The legal battles looming over Kalshi and Polymarket raise significant questions about the future of prediction markets and their place in both finance and betting industries. As regulatory bodies take a keener interest, other states are likely to follow Baltimore's lead, reassessing the legality and consumer protections surrounding such platforms. Companies in this space must quickly adapt to changing regulatory landscapes or risk being sidelined. That said, it’s also a moment for advocacy: if the regulatory framework can be shaped more transparently, perhaps innovative platforms can emerge that prioritize user safety without stifling competition.

For everyday users, the implications are clear: there’s a critical need for vigilance. As more states develop ecosystems around legal sports betting, understanding where and how to engage safely becomes essential. Lawsuits like these serve as a reminder that, amid the allure of potential profits, there are significant risks and responsibilities that users and providers alike must acknowledge.
