A judge is reviewing arguments on whether to break up Google’s monopoly in online advertising. The decision could reshape the company as it competes in the AI space. A ruling is expected next year.

Alphabet's shares rose 8% following a ruling that minimized the consequences of a major antitrust case against Google, which found it held an illegal monopoly in internet search. U.S. District Judge Amit Mehta ruled against forced divestitures of key assets like Chrome and Android but mandated changes to Google's distribution practices and data sharing. The DOJ emphasized the need for remedies to enhance competition in the search market and prevent anticompetitive behavior in Google’s GenAI products.

A federal judge ruled that Google has created an illegal monopoly in the online advertising sector, violating the Sherman Antitrust Act. This ruling, the second in recent months against Google’s market practices, may prompt the Justice Department to push for the sale of some of the company's advertising assets. Google plans to appeal the decision.

The Justice Department and Google are engaged in a legal battle over the remedies for Google's monopoly in the search engine market, following a ruling that found the company acted illegally to maintain its dominance. The DOJ is demanding aggressive measures, including the divestiture of Google's Chrome browser and the cessation of exclusive agreements with phone manufacturers, while Google argues that these proposals are extreme and unnecessary. The case is being compared to significant historical antitrust cases, such as the Microsoft case from the late 1990s.

Meta has concluded its defense in the FTC's monopoly trial regarding its acquisitions of Instagram and WhatsApp, with the FTC pushing for a breakup due to alleged anti-competitive practices. Despite Meta's confidence in a favorable outcome, experts point out the challenges of reversing mergers, and a ruling from Judge Boasberg is expected later this year.

Google is in the final phase of an antitrust case focusing on its dominance in digital advertising. U.S. District Judge Leonie Brinkema is evaluating potential remedies to enhance competition in the ad tech market, following earlier rulings that found Google had illegally monopolized online auction technology.
