Microsoft CEO Warns Google's AI Could Strengthen Search Dominance, Antitrust Trial Seeks to Counter Google's Entrenched Position

Microsoft CEO Satya Nadella testified that Google's dominance in search could become even greater with AI, giving it unmatched data to train algorithms.

Nadella said Microsoft has struggled to gain search share despite large investments, only achieving single digits against Google's 90% share.

The DOJ antitrust lawsuit against Google alleges it illegally protects its search monopoly through exclusivity deals and other anticompetitive practices.

The lawsuit relies on similar theories used in the 1990s Microsoft case, when Microsoft was found to repeatedly violate antitrust law.

Nadella said it's difficult for rivals to make breakthroughs against Google's entrenched position, but it's unclear if the trial can lead to meaningful change.
