Google’s ad tech remedies trial kicked off Monday as the search giant looks to prevent an ad tech breakup that would fundamentally alter the future of the open internet. If successful, the DOJ’s case against Google would reshape how open-web ads are bought and sold. Multi-billion dollar opportunities will open for competitors, potentially creating a more competitive—but less predictable—ad tech landscape for advertisers.

The news: Google is launching Offerwall, a new Ad Manager tool that lets users unlock publisher content through ads, surveys, or payments—part of a broader effort to mend relationships with publishers facing traffic loss from AI Overviews and eroding ad share. Publishers say Google pays less than rivals like PubMatic and Magnite, and AI-driven zero-click searches have dropped site traffic significantly. Our take: With a DOJ remedies trial looming and ChatGPT traffic rising fast, Google’s publisher outreach isn’t just damage control—it’s existential. If AI is to remain useful and ethical, supporting the content it’s trained on is a must.

DOJ continues the push to dismantle Google: The search giant will need to battle regulators to defend its dominance, while advertisers should prepare for fragmentation.
