Sources: 9. Developments: 2. California Attorney General Rob Bonta is engaged in multiple antitrust legal actions. While a recent attempt to secure a preliminary injunction against Amazon for alleged price-fixing was denied by the San Francisco Superior Court, Bonta is simultaneously leading a 12-state coalition in a federal lawsuit to block the $110 billion acquisition of Warner Bros. Discovery by Paramount Skydance. Opponents of the Paramount-Warner Bros. Discovery merger argue that the deal would allow the new entity to control roughly one-third of nationwide theatrical films and basic cable programming. In response, Paramount Skydance CEO David Ellison is reportedly exploring political maneuvers and has allegedly considered threatening to move Los Angeles studio operations out of California if a settlement is not reached by October 1. Proponents of the merger maintain that such consolidation is necessary for traditional studios to achieve the scale required to compete with major technology firms like Amazon, Apple, and Netflix. ## Timeline ### 2026-09-11: Paramount and Warner Bros.
