The Government's Antitrust Complaints Against Big Tech

Joseph Stone Capital summarizes the status of the major U.S. antitrust complaints against Google, Meta, Amazon and Apple, and why market participants follow them.

GARDEN CITY, N.Y., October 26, 2026 -- Joseph Stone Capital, LLC, a full-service broker-dealer, today published a review of the major U.S. government antitrust complaints against the largest technology companies. Several reached key rulings in 2026, and the outcomes may shape competition in search, digital advertising, social media, e-commerce and smartphones.

"These complaints were filed years ago, but 2026 is when many of them began producing remedies," the firm said. "Courts have so far favored conduct rules over breakups, and appeals are still underway."

Where the complaints stand:

1. Google, advertising technology. The Justice Department and a group of states filed their complaint in January 2023. On September 2, 2026, U.S. District Judge Leonie Brinkema in Alexandria, Virginia declined to order Google to sell its AdX ad exchange but ordered behavioral remedies, including integration with the open-source Prebid framework, real-time bidding into competing publisher ad servers, publisher data-export rights, auction disclosure and a ban on self-preferencing. Google and the government filed a joint proposed final judgment on October 2, 2026, disagreeing mainly on monitoring and enforcement.

1. Google, search. A September 2025 remedies order barred exclusive default search contracts for six years and required certain data sharing with rivals, but did not require a sale of Chrome or Android. Both Google and the Justice Department, joined by states, have appealed; Google filed its reply brief in the D.C. Circuit on September 29, 2026.

1. Meta. The Federal Trade Commission's complaint over Meta's acquisitions of Instagram and WhatsApp was rejected after trial in November 2025, when the court found the FTC had not proven Meta holds a monopoly. The FTC appealed in January 2026; final briefs in the D.C. Circuit are due October 20, 2026.

1. Amazon and Apple. The FTC's 2023 complaint against Amazon and the Justice Department's 2024 complaint against Apple are proceeding, with trials not expected before 2027, according to Reuters.

Why it matters for private markets: remedies such as data sharing, interoperability and limits on exclusive contracts could affect the competitive landscape for venture-backed and late-stage private companies in advertising, search and artificial intelligence. Any such effect is uncertain, and appeals could change the outcomes.

"For anyone following technology markets, the status of these cases is worth tracking alongside earnings," the firm said. "Rulings can still change on appeal."
