What changed

Iowa Attorney General Brenna Bird and Montana Attorney General Austin Knudsen filed a motion asking the U.S. Supreme Court to stop California and 11 other states from pursuing their antitrust case against the pending Paramount–Warner Bros. Discovery transaction. The applicants argue that the challenge conflicts with federal enforcement and harms their states' economic interests. They want the opposing states to respond by September 15 and the Court to consider the matter at its October 9 conference. California's attorney-general office told TheWrap that it was reviewing the filing.

How this differs from the stalled settlement track

FanBriefer's August 26 edition reported that California Attorney General Rob Bonta cancelled a planned settlement meeting after confidential details appeared in the press and said no replacement talks were scheduled. Iowa and Montana are not announcing a renewed negotiation or a settlement. Their application instead asks the Supreme Court to intervene in a dispute among states and prevent the existing case from proceeding. The underlying state trial is still scheduled for March 2027, and Paramount has agreed to delay closing until after that trial's outcome or June 1, 2027, whichever comes first.

What fans can and cannot conclude

The request matters because control of Warner Bros., HBO, DC and a large group of cable networks remains unsettled. A granted injunction could affect the transaction's timetable and bargaining pressure around possible remedies. Nothing in the filing, however, shows that the Supreme Court will take the case, grant relief or permit the merger to close. It also does not erase California's concerns about competition or establish how films, series, streaming libraries and franchise teams would be organized under combined ownership. The next meaningful evidence is a response schedule, a Court order or a renewed settlement meeting.
