The cases heavily echo the turn-of-the-century Microsoft antitrust case in several respects, most notably that Google, like Microsoft before it, has evaded the forced breakup requested by regulators.
Here’s our condensed timeline of the two overlapping lawsuits and their progress through the court system.
Sep. 2, 2026, advertising lawsuit: In a second big win for Google, Judge Brinkema rules that the company does not have to sell its AdX ad exchange. The search giant is also not required to open-source the final-auction logic in its DoubleClick for Publishers (DFP) ad server or divest its DFP business. Behavioral remedies are sealed while the parties identify confidential information for redaction.
Sep. 2, 2025, search lawsuit: In a significant win for Google, Judge Mehta rules that the tech giant does not have to divest its Chrome and Android businesses as the US government had requested, and it will be allowed to continue paying Apple and other browser makers for default search placement. To level the competitive playing field, Google will have to share search index and user-interaction data with rivals and offer search results syndication.
April 21, 2025, search: The remedy phase of Google’s search antitrust trial begins with Judge Mehta presiding. Federal prosecutors warn that Google might leverage artificial intelligence to entrench its search monopoly, demanding “strong measures” to prevent the tech giant from extending its market control into the AI era. These include requiring Google to divest Chrome, end exclusive default search agreements, license its search data to competitors, and potentially sell its Android operating system if other remedies fail.
