- Five claim types failed: reciprocal dealing, tying, monopoly maintenance, attempted monopolization and leveraging, and California unjust enrichment.
- The court declined jurisdiction over the unjust enrichment claims, so it did not rule on their merits.
- Mehta wrote that he is not unsympathetic to creators whose content Google takes and repurposes without compensation.
US District Judge Amit P. Mehta has dismissed the amended antitrust complaints that Penske Media Corporation and Chegg brought against Google over AI Overviews, in rulings reported on 1 October 2026. The court found that the publishers had not pleaded claims that meet the requirements of federal antitrust law, and in the Penske case the dismissal was granted without prejudice. The judge also wrote that he does not treat the publishers' alleged harms lightly.
What Judge Mehta decided in the Penske and Chegg cases
Penske Media, which owns Rolling Stone, The Hollywood Reporter, Billboard and Variety, sued Google over AI Overviews about a year before the ruling. Chegg, the education company, brought a separate complaint on similar grounds. Both cases were before Judge Mehta. Google moved to dismiss the amended complaints, and the court granted the motions.
According to Search Engine Journal, the order in the Penske case states that Google's motion to dismiss was granted without prejudice and that the order is final and appealable. The court rejected five categories of claims across the two cases: reciprocal dealing, tying, unlawful monopoly maintenance, attempted monopolization and monopoly leveraging, and unjust enrichment.
The decision is a ruling on the pleadings. The judge did not hold a trial or find that publishers suffered no harm. He found that the complaints, as written, did not allege the facts that the Sherman Act claims require.
The five claims and why each failed
The table below summarises how the court dealt with each category of claim, based on Search Engine Journal's and Search Engine Roundtable's reporting of the memorandum opinion.
| Claim | Court's reason for dismissal |
|---|---|
| Reciprocal dealing | No plausible agreement alleged; "an expectation is not an agreement" |
| Tying (Penske) | Search and AI Overviews not shown to be separate products with separate demand |
| Monopoly maintenance | Publishers lack antitrust standing in the general search services market |
| Attempted monopolization and leveraging | No plausibly defined markets; Count V (Chegg) and Count VI (Penske) dismissed |
| Unjust enrichment (California law) | Court declined supplemental jurisdiction after dismissing all federal claims |
Reciprocal dealing: "an expectation is not an agreement"
The publishers' central theory was that Google effectively makes them hand over their content for free in exchange for visibility in Search, then uses that content to answer questions directly in AI Overviews. Reciprocal dealing requires an agreement between two parties to exchange business. Judge Mehta found no plausible agreement in the complaints. He wrote: "Plaintiffs have pleaded only that they have an 'expectation' that Google will send them search traffic if they make their content available for free. But an expectation is not an agreement."
Search Engine Roundtable reported that the court pointed to what was missing: negotiated terms, commitments, communications showing mutual assent, or other facts demonstrating a meeting of the minds. The court treated automated crawling and publishers' expectation of referral traffic as general search engine functionality, not as a coercive bargain.
Tying: no separate product
A tying claim requires two separate products, where power over one is used to force acceptance of the other. Penske did not plausibly establish that Google Search and AI Overviews are separate products with separate consumer demand, so the tying claim failed.
Monopoly maintenance: no antitrust standing
The publishers argued they had standing in the general search services market, either as "suppliers" of search index data and "purchasers" of search referral traffic, or because their injuries were "inextricably intertwined" with those of Google's new AI competitors. The judge wrote that "neither theory persuades." Standing here means the plaintiffs had not suffered the kind of injury that allows them to bring that particular antitrust claim.
Attempted monopolization and monopoly leveraging: markets not defined
These claims required the plaintiffs to define the markets Google was allegedly trying to monopolize and show a dangerous probability of success. The judge found that they did not define plausible markets. Of Penske's proposed online publishing market, he wrote that the plaintiffs did not "even attempt to quantify Google's market share" in it. For Chegg, he wrote that it had not plausibly pleaded a dangerous probability of monopolization in a market where it participates.
Unjust enrichment: left to state law
The unjust enrichment claims were brought under California law. Once all the federal claims were gone, the court used its discretion to decline supplemental jurisdiction over them. That means the court did not decide whether those state-law claims have merit.
What "without prejudice" does and does not mean
A dismissal without prejudice generally does not bar a plaintiff from bringing the claims again, for example with a new complaint that alleges the missing facts. The Penske order was also described as final and appealable, which means Penske can ask the appeals court to review it. These are general legal concepts, not predictions.
The reports did not say whether Penske or Chegg will appeal, refile, or pursue the state-law claims in another court. The reports also did not give the exact filing date of the order, and Search Engine Journal's description of "without prejudice" and "final and appealable" refers specifically to the Penske order. Readers should not assume either company has announced its next step.
The judge's comments on publisher harm
The opinion includes an unusual acknowledgement. Judge Mehta wrote that "the court does not treat Plaintiffs' alleged harms lightly. Nor is it unsympathetic to the situation publishers now find themselves in, and the knock-on consequences to journalists, educators, and other online creators whose content Google takes and repurposes without compensation."
That passage does not change the outcome, but it does clarify what the ruling is about. The court did not say that AI Overviews are harmless to publishers. It said that the specific antitrust theories in these complaints did not meet the legal tests.
Publisher groups responded critically. Search Engine Roundtable quoted Jason Kint, chief executive of Digital Content Next, a US publisher trade body, who argued that publishers have now lost both the route through the government's search case and the route through their own lawsuits, and that someone with authority still needs to address the problem.
A separate ruling that went the other way
Search Engine Roundtable also noted a different case. A 30 September 2026 ruling in the Google ad tech antitrust litigation allowed core claims by Gannett, Daily Mail and a class of digital publishers to proceed. That case concerns Google's advertising technology stack and programmatic ad marketplace. It has nothing to do with AI Overviews, so it should not be read as a counterweight to the Mehta dismissal on AI content.
What this means for AI Overviews and search visibility
The following is analysis, not something the court or Google said. With these two cases dismissed at the pleading stage, there is no court order in the Penske or Chegg cases that would force changes to how AI Overviews use publisher content. For the time being, brands and publishers should plan on the assumption that AI Overviews will keep working as they do now.
That shifts attention to what site owners can control. AI Overviews draw on pages Google has crawled, and they cite some of those pages as sources. Being one of the cited sources is now a visibility goal in its own right, separate from ranking a blue link. The work behind it, often called generative engine optimization, involves clear and extractable facts, well-structured pages, and content that answers the questions people actually ask. Our generative engine optimization service covers this, and our AI SEO service looks at how a site performs across AI search features.
It is also worth separating legal risk from traffic risk. The ruling changes nothing about publishers' traffic from AI Overviews. Any loss of clicks that existed before the decision still exists after it. What changed is the near-term likelihood that US litigation will alter Google's behaviour, which these dismissals reduce for now.
What this means for Thai marketers
The cases were filed and decided in a US federal court under US antitrust law, so the ruling has no direct legal effect in Thailand. Its practical effect is indirect: one route that could have forced Google to change AI Overviews globally has been closed at this stage. Thai publishers and brands that are losing clicks to AI Overviews should not expect US litigation to change the feature soon. Measuring whether your pages are cited in AI answers, and improving the pages that should be, is a more useful near-term focus than waiting for a court outcome.
FAQ
Did the court rule that Google's AI Overviews are legal?
No, the court ruled that the publishers' complaints did not plead valid federal antitrust claims. Judge Mehta dismissed the claims at the pleading stage and explicitly said he does not treat the publishers' alleged harms lightly.
Can Penske Media appeal or refile?
The Penske order was granted without prejudice and is described as final and appealable, which generally allows both an appeal and a future complaint. The reports did not say whether Penske plans to do either.
Why did the reciprocal dealing claim fail?
It failed because the publishers did not allege an actual agreement with Google. The judge wrote that they pleaded only an "expectation" of search traffic, "but an expectation is not an agreement."
Does this ruling affect websites in Thailand?
Not directly, because it is a US court decision under US law. It does mean AI Overviews are unlikely to change as a result of these two lawsuits in the near term.
What were the unjust enrichment claims, and were they rejected on the merits?
They were California state-law claims, and the court did not rule on their merits. After dismissing every federal claim, it declined to exercise supplemental jurisdiction over them.
The bottom line
Judge Mehta's ruling closes the main US antitrust route publishers had tried against AI Overviews, at least as these complaints were pleaded, while recognising the harm publishers describe. For marketers, AI Overviews stay as they are, and the practical task is to make sure your content is the kind those answers cite.
