Federal regulators and a coalition of states have accused a major technology company of systematically exploiting its dominance in digital advertising to inflate prices for businesses, potentially costing them billions. The lawsuit claims the company used its control over ad auctions to manipulate pricing algorithms, giving brands and sellers little choice but to pay inflated rates. Legal experts suggest the case could set a precedent for antitrust enforcement in the tech industry, raising questions about how platforms with near-monopolistic power operate. If true, the allegations would mark one of the most significant challenges yet to the company’s business practices.
