GOOGLE KEEPS AD EXCHANGE, MUST OPEN IT UP

The decision marks a significant outcome in the US government's antitrust case against Alphabet Inc. Rather than forcing a breakup of Google's advertising business, the judge ordered the tech giant to make its ad tech infrastructure interoperable with rival systems. Google's ad exchange—a digital marketplace where publishers sell ad space and advertisers buy it—has been central to the government's antitrust concerns. Regulators argued the company wielded too much control over multiple layers of the ad tech supply chain, giving it unfair advantages. The interoperability requirement aims to address competition concerns while keeping Google's business intact. The company will need to ensure its ad tech tools function alongside those of competitors, potentially reducing barriers for rival ad platforms to operate effectively. This ruling represents a middle path between two outcomes: full divestiture and no action. It avoids the dramatic restructuring of a breakup while still imposing operational constraints intended to level the playing field. The decision comes after years of investigation by the Department of Justice and state attorneys general. Multiple divestitures were initially considered as potential remedies to alleged monopolistic practices in digital advertising. Google's advertising business generates the vast majority of Alphabet's revenue. A forced sale would have represented one of the largest tech breakups in decades, comparable to historical antitrust cases. The interoperability mandate requires Google to maintain technical standards and provide rival platforms access to necessary data and systems. Implementation details and timelines remain to be worked out through ongoing legal proceedings. This case reflects broader regulatory scrutiny of Big Tech's dominance in advertising markets. However, this particular outcome suggests courts may favor competition remedies over structural breakups in tech antitrust cases.
