A US judge rejected the Department of Justice's bid to break up Google's ad business, opting instead for rules to govern Google's ad market operations. The ruling follows a broader DOJ effort to regulate big tech's dominance, specifically targeting Google's control over digital advertising infrastructure.

◆ ◆ The Wire takeaway
Google's ad business will operate under new rules rather than a breakup, so ad tech founders should pivot to compliance and positioning for continued market dominance. The ruling leaves a narrow window for regulatory changes without structural dismantling.
