Publishers File Suit Challenging Google's Ad-Tech Monopoly

The Atlantic filed an antitrust lawsuit yesterday accusing Google of illegally depriving publishers of advertising revenue by tying its publisher platform to its dominant ad exchange. The complaint builds on Judge Leonie Brinkema’s April ruling that Google controls over 50 percent of global ad exchanges and roughly 90 percent of publisher ad platforms, alleging self-preferencing and bid manipulation. The case could yield damages and set legal precedent amid wider AI-driven traffic disruptions.
