Court orders Google to open advertising technologies to competitors and share data
Judge Leonie Brinkema ordered Google to ensure its advertising technologies are interoperable with competitors and to share advertising data with customers. The ruling does not require a breakup of the advertising business: the judge called such a step “neither realistic nor necessary.” Google said it disagrees and intends to appeal.

5Key points
- On September 17, 2026, Judge Leonie Brinkema ordered Google to ensure its advertising technologies are interoperable with competitors and to share advertising data with customers.
- Google must also appoint an internal antitrust compliance officer and give competitors real-time access to auction bids through AdX.
- Google said it disagrees with the ruling and intends to appeal.
Why it matters
In April 2025, Brinkema found that Google maintained an illegal monopoly in some segments of internet advertising technology. The company’s anticompetitive conduct substantially harmed publisher customers, the competitive process, and consumers of information on the open internet.
What changed
A U.S. court previously ruled that Google is not required to sell its advertising exchange after the antitrust loss. This is the third of Google’s three antitrust cases to reach a decision, and the company is emerging from a period of legal uncertainty almost unscathed. The new ruling adds behavioral remedies — interoperability, data sharing, and compliance oversight — but not a breakup of the business.
What's Next
Google intends to appeal; the parties have 14 days to request redactions of confidential information.
