Court issues sealing order on U.S. search warrant application in antitrust probe in N.D. Cal.

The United States filed an application for a search warrant targeting four physical locations and one individual under investigation for potential violations of Section 1 of the Sherman Act, 15 U.S.C. § 1. The case is docket number 26-mj-70012 in the Northern District of California.

The government alleges that the subject of the investigation may have engaged in anticompetitive conduct, which typically involves agreements that restrain trade or fix prices. The court has not yet assigned a judge to the matter, and the case remains active.

The warrant application suggests a broad scope, covering multiple locations and a person, indicating the government’s intent to gather extensive evidence. The investigation is still in its early stages, with limited public filings. The most recent docket entry shows a motion to seal, which the court ordered on May 12, 2026.

This reflects the sensitive nature of the investigation, as sealing motions often aim to protect investigative details from public disclosure.

The case is part of the government’s ongoing efforts to enforce antitrust laws, which can lead to significant penalties and changes in business practices if violations are found. The absence of a judge assignment means the case is still moving through initial procedural steps. The government’s next filings will likely clarify the scope and targets of the investigation further.

Watchers should monitor the docket for the appointment of a judge and any rulings on the motion to seal. These developments will shape how much information becomes public and how the investigation proceeds. The government’s next moves, including potential unsealing or further motions, will signal the investigation’s direction and intensity.
