On July 20, 2026, the U.S. District Court for the Northern District of California issued an order blocking Paramount Skydance's acquisition of Warner Bros. Discovery (WBD) and any related integration efforts for 14 days. This does not mean the $110 billion deal has been finally ruled illegal. Still, a transaction that the U.S. Department of Justice concluded investigating in June cannot proceed until a preliminary injunction hearing scheduled for August 3. What moved the court was not the scale of the streaming market, but rather concentration in the distribution of theatrically released films nationwide.
The 14-Day Order Also Halts Integration Work
Judge Araceli Martínez-Olguín's order prohibits the two companies not only from completing the acquisition but also from directly or indirectly consolidating or combining operations based on the deal. This applies to officers, employees, and agents of both companies as well. It is not merely a measure that puts a signed contract on hold for 14 days.
The purpose of the injunction is to preserve the court's ability to review the merits of the case. If the two companies were to share confidential information, merge divisions, and lay off or reassign employees beforehand, it would be difficult to later restore the competitive landscape. The judge recognized this irreversibility as constituting irreparable harm.
The states must file for a preliminary injunction by July 23, and the companies must respond by the 27th. The states' reply is due by the 30th. The hearing will be held in Oakland at 3:00 PM on August 3. Even if both parties agree to extend the schedule, the temporary restraining order will remain in effect until that hearing.
The Weight of 27% Film Distribution Share and an HHI of 2074
Twelve states, including California, filed suit on July 13, alleging that the acquisition violates Section 7 of the Clayton Act. The complaint identifies three markets: distribution of theatrically released films nationwide, distribution of anticipated blockbuster films, and licensing to basic cable networks. In this order, the judge examined in detail only the first market—nationwide theatrical film distribution. This is because sufficient evidence in even one market is enough to issue an emergency injunction.
According to the states' analysis, the combined market share would reach 27%. The Herfindahl-Hirschman Index (HHI), a measure of market concentration, would rise by approximately 359 points to reach 2074. Based on these figures, the judge determined that the states had presented a strong argument that competition would be significantly harmed. While the companies dispute how the market should be defined, the order notes that, for purposes of this hearing, the argument proceeded on the basis of the states' definition, and the companies did not present evidence directly rebutting the concentration figures.
However, the court has not determined the outcome of the antitrust lawsuit itself. The companies countered that the states failed to properly account for new entrants into film distribution and changes in the market. The judge acknowledged that disputes remain over both facts and legal assessment, and, in the absence of a complete evidentiary record, concluded only that "serious questions on the merits remain." Whether the 27% figure will hold up through final judgment remains to be tested.
The Market the DOJ Saw, and the Market the 12 States Carved Out
On June 12, the DOJ's Antitrust Division concluded an eight-month investigation. After reviewing more than 2 million documents submitted by over 80 executives, it concluded that the acquisition was unlikely to harm competition in subscription video streaming, linear television, or theatrical film development, production, and distribution. In fact, it suggested that the combined company would strengthen competitive pressure on major streaming providers. Because the two companies agreed to information sharing, the DOJ and the states shared information, and offices of state attorneys general also participated in the investigation.
Even so, the 12 states sued by treating nationwide theatrical film distribution and cable network licensing terms as separate markets. Paramount counters that combining the two companies' capital and content is necessary to compete against Netflix and major tech companies, and that the states have mischaracterized the current competitive landscape. The disconnect in the debate is clear. Paramount and the DOJ place heavy weight on the effect of increasing the number of competitors in the broader video market, while the states are concerned about the disappearance of the opportunity for theaters and cable operators to pit Paramount and WBD against each other.
In this instance, the judge based the emergency ruling solely on the latter framework. The judge also rejected the argument that efficiency gains in streaming operations could offset reduced competition in the relevant market of nationwide theatrical film distribution, finding it could not serve as a valid defense. While this order does not overturn the DOJ's conclusion of its investigation, it has made clear that an executive branch determination alone cannot foreclose a state lawsuit.
August 3 and September 30: Two Deadlines That Will Determine the Deal's Fate
Under the agreement Paramount and WBD signed on February 27, WBD shareholders will receive $31 in cash per share. The deal values equity at $81 billion and enterprise value, including debt, at $110 billion. WBD shareholders approved the agreement on April 23 with 1,742,843,087 votes in favor, and the deal was originally expected to close in the third quarter of 2026.
If the preliminary injunction is granted, the 14-day pause will turn into a long-term freeze pending litigation. If it is denied, the temporary restraining order will move toward expiration, but the acquisition will still need to satisfy remaining closing conditions. First, August 3 will be the day that tests whether the states' market definition and concentration evidence are strong enough to support a long-term injunction.
The other key date is September 30. Under the agreement, if the acquisition has not closed by that date, Paramount must pay WBD shareholders an additional $0.00277778 per share per day. This additional amount is capped at $0.25 per 90-day period. The court also acknowledged that the companies will not bear any holding costs associated with delay through the end of September. If the August hearing marks the legal turning point, the end of September marks the point at which delay translates directly into acquisition costs.
