Executive Summary
Baltimore files lawsuit against Polymarket and Kalshi alleging unlicensed sports betting operations in violation of Maryland gambling laws.
BALTIMORE, MD, Aug. 14, 2026 — In a major escalation of municipal enforcement against prediction market platforms, the City of Baltimore filed lawsuits in Circuit Court on August 13, 2026 against leading event-wagering operators Polymarket and Kalshi. The complaint, led by Mayor Brandon M. Scott, alleges that both platforms are conducting unlicensed sports betting operations in violation of Maryland consumer protection and gambling statutes.
According to court documents, the lawsuit contends that Polymarket and Kalshi allow residents to stake cryptocurrency and fiat balances on athletic outcomes, political races, and pop culture events under the guise of financial derivative trading, bypassing state licensing fees, consumer protection guardrails, and age verification standards enforced on traditional sportsbooks.
The legal filing comes amidst broader regulatory scrutiny across major U.S. metropolitan areas. City officials highlighted that event-contract platforms have rapidly expanded their consumer footprint without obtaining state gaming credentials or submitting to local wagering tax oversight.
"This lawsuit signals a turning point for prediction markets operating across U.S. municipalities," said Sophia Chen, Regulatory Editor at CryptoCasinoMedia. "City and state regulators are no longer treating event contracts as distinct financial products—they are actively enforcing sports betting laws across all prediction interfaces."
