DraftKings has taken legal action against the City of Philadelphia, filing a lawsuit on Thursday aimed at halting the enforcement of a local consumer protection law and any related investigations into the sports betting firm.

In its complaint submitted to the federal court in Philadelphia, DraftKings argued that existing Pennsylvania laws concerning consumer protection and unfair trade practices prevent the city from implementing a 2024 ordinance designed to establish a municipal framework for consumer protection.

DraftKings also challenged an April 24 subpoena ​from the City of Philadelphia Law Department, which sought information related to various ⁠activities including sports wagering, promotional credits and bonuses, VIP programs, and policies intended to thwart problem ​gambling.

The Boston-based company wants a judge to end the city’s probe, and declare that the ordinance is ​both pre-empted by state law and unenforceable when applied to DraftKings’ licensed gaming activities.

Philadelphia’s ordinance was signed in June 2024 by Mayor Cherelle Parker. Her office did not immediately respond to requests for comment. The Law Department had ​no immediate comment.
