Baltimore Sues Kalshi and Polymarket

Mayor Brandon Scott and the City Council filed suit Thursday, alleging illegal unlicensed sports betting — the first major U.S. city to sue both platforms.

Baltimore Mayor Brandon Scott and the Baltimore City Council filed suit Thursday against Kalshi and Polymarket, alleging consumer-protection violations, according to gamblerss.com.

The lawsuit accuses both companies of operating illegal, unlicensed sports-betting platforms. Those claims are allegations, not established findings.

Baltimore challenges both platforms

The action puts both prediction-market platforms under scrutiny from Baltimore’s mayor and City Council. The available summary identifies sports betting and consumer protection as the focus of the complaint.

The report was published Oct 10, 2026, at 10:54 AM ET. Its full text was unavailable, and the supplied summary does not identify the specific legal provisions invoked, the relief sought or either company’s response.

What it means for prediction markets

  • Legal classification is central: Baltimore’s allegations challenge the platforms’ activities as illegal, unlicensed sports betting.
  • The outcome remains unresolved: The available material establishes that a lawsuit was filed, not that a court has ruled against either platform.
  • Operational effects are unspecified: The summary provides no basis to conclude that the filing has changed market access or trading availability.
