Penske Media Corporation’s antitrust case against Google over AI Overviews has been dismissed. The decision, reported October 1, did not turn on Google’s market share or AI training data. It turned on a simpler question: had Google ever promised to send publishers a specific amount of traffic? Judge Amit P. Mehta said no.
“An expectation is not an agreement,” Mehta wrote in the ruling.
The case and the missing contract
Penske filed the suit on September 12, 2025 in the US District Court for the District of Columbia, naming Google LLC and Alphabet Inc. as defendants. It brought the case alongside 14 subsidiary publications, including Rolling Stone, Variety, Billboard, The Hollywood Reporter and Deadline.
The complaint was heavy with numbers: 89.2% search market share, 94.9% mobile share, a 34.5% click-through rate reduction from AI Overviews in an Ahrefs analysis, and roughly 20% of searches returning a Penske link carrying an AI Overview in late 2024 and early 2025. The judge’s dismissal did not hinge on any of them.
At its core, Penske argued that Google had a reciprocal deal: publishers supplied content, and Google supplied referral traffic. AI Overviews broke that deal by answering queries directly and sending fewer visitors onward. Judge Mehta found that the complaint “failed to plead any actual agreement whereby Defendants promised to ‘sell’ Plaintiffs any specific amount of traffic.”
Why this matters for search marketers
The ruling is a useful distinction for anyone who depends on organic search. Search traffic has always been an output of Google’s ranking system, not a contractual entitlement. AI Overviews change how much of that output actually reaches a site.
- AI Overviews can reduce click-through rates without creating a legal claim.
- Market dominance alone does not prove a traffic-for-content contract.
- Publishing quality content does not, by itself, create a right to referral visits.
Judge Mehta was not dismissive of the harm. He acknowledged the consequences for journalists, educators and online creators “whose content Google takes and repurposes without compensation.” Digital Content Next CEO Jason Kint put it more bluntly: “Google is using its dominance to fundamentally undermine the open web.”
What to do about it
Marketers should treat AI Overviews like an algorithm shift, not a contract breach. That means measuring your exposure and diversifying acquisition instead of waiting for a court to restore clicks.
Publishers are trying to build the missing measurement layer. The SPUR coalition released version 1.0 of a content telemetry standard on October 2, designed to record when content is retrieved, cited, presented and engaged with inside AI systems. If adoption grows, those records could support future licensing negotiations rather than antitrust claims.
The practical takeaway
For performance and SEO teams, the lesson is not that Google wins. It is that nobody wrote the web’s central economic relationship down. That gap is now a planning risk: if you treat referral traffic as guaranteed, you are building on an expectation, not an agreement. The teams that will weather this are those that measure AI Overview visibility, test alternative traffic sources, and keep their content strategy tied to business outcomes rather than rankings alone.
