Google's AI Overviews survived antitrust court. What can publishers do now?

If you publish anything on the open web, here is the question this week's ruling leaves you with: now that a federal judge has thrown out the antitrust cases against Google's AI Overviews, what can a publisher actually do about its content being summarised by Google's AI? The answer is less about courtrooms than about a settings toggle most site owners have not looked at yet.

The short answer

The antitrust route is closed for now, at least at the trial-court level. On September 30, 2026, U.S. District Judge Amit P. Mehta dismissed the federal antitrust claims brought by Penske Media and Chegg over AI Overviews, holding that publishers never had an enforceable bargain that traded content for traffic. The practical lever that remains is technical and voluntary: since August 31, 2026, Google says its Search Console opt-out for generative AI Search features is available to all websites worldwide. That control is real, but it is a trade-off, not a remedy. Opting out removes you from AI Overviews and AI Mode, and the traffic and impressions that come with them.

What the court actually decided

Penske Media, owner of titles such as Rolling Stone, Variety and The Hollywood Reporter, sued Google in September 2025; Chegg had brought a parallel case. Both argued that Google had long operated an implied deal: publishers let Googlebot crawl their pages for free, and Google sent back referral traffic. AI Overviews, they said, broke that deal by answering queries directly with their content.

Judge Mehta rejected that framing in a 41-page memorandum opinion, according to Forbes, which describes it as coming with a final, appealable order. As quoted by Press Gazette, the court 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."

The opinion continues, per Android Authority: "It is simply how a general search engine works." The court also wrote that "merely incanting the phrase 'historical course of dealing' cannot plausibly convert two parties' independently self-interested conduct into a contract."

Four theories, four rejections

Based on Forbes' summary of the opinion, the dismissal rested on several separate grounds:

• Reciprocal dealing: no plausible agreement was pleaded, only a pattern of independent behaviour.
• Tying (Penske only): the court treated AI Overviews as part of Google Search, not a separate product, because both meet the same demand: answering a search query.
• Monopoly maintenance and leveraging: the publishers' losses fell in publishing markets, not in general search, where the alleged restraint occurred. Forbes notes the court pointed to Google's search share of roughly 80% by 2009 and 89.2% by 2020, long before AI Overviews arrived in 2024.
• Market definition: Penske's "online publishing" market was found implausibly broad, and Chegg's educational publishing market insufficiently specified.

The court declined supplemental jurisdiction over the California unjust-enrichment claims rather than ruling on their merits. Notably, the judge did not dismiss the harm itself. He acknowledged "knock-on consequences to journalists, educators, and other online creators whose content Google takes and repurposes without compensation," as PPC Land reports, while writing, per Forbes, that antitrust law is not a substitute for a legislature dealing with "economic dislocation caused by new innovation."

A pattern, not a one-off

This is the same judge who found Google to be a search monopolist in the Justice Department case, and it is the second time this year he has dismissed a publisher's antitrust suit against Google. In March, he dismissed a suit by Helena World Chronicle and Emmerich Newspapers, finding they had "not plausibly established that Google has monopoly power in the online news market," MediaPost reported. The lesson for publishers: a search monopoly finding does not automatically translate into a claim for those downstream of it.

The lever that does exist: the opt-out toggle

While the lawsuits were pending, the regulatory picture moved in the UK. On June 3, 2026, the Competition and Markets Authority imposed conduct requirements on Google Search that let publishers prevent their content from powering AI features such as AI Overviews, require clear attribution links, and allow publishers to opt out of fine-tuning. Google has nine months to comply.

Google's response went beyond the UK. Its announcement introduced a Search Console toggle that lets site owners "decide if they want their site to appear in and help ground responses in our generative AI Search features (like AI Overviews, AI Mode or AI Overviews in Discover)." An update dated August 31, 2026 states: "we've rolled out these features to all websites worldwide." Google also says the control "will not be used as a ranking signal for search results outside of these generative AI Search features."

What each control does

1. The Search Console toggle: keeps your site out of AI Overviews, AI Mode and AI Overviews in Discover, while leaving classic results in place. Google states that sites that opt out will not get traffic or impressions from those features.
2. Snippet controls: Google's documentation for AI features says to use nosnippet, data-nosnippet, max-snippet or noindex to limit what is shown. These are blunter: they also change how your page looks in regular results.
3. Google-Extended: per the same page, this governs AI training and grounding "in some of Google's other systems". It is not the switch for AI Overviews.

How to decide

The ruling removes the hope that a court would force a content-for-traffic bargain. So the decision is commercial. A useful way to frame it: if AI Overviews mostly answer the question your page exists to answer (definitions, quick facts, homework help), the summary may be substituting for your visit, and opting out costs you little traffic that you were going to get anyway. If your pages are cited as sources in AI answers and those citations still send qualified visitors, staying in may be worth it. Measure before you flip the switch: compare clicks and impressions for the queries where AI features appear, then test on a section of the site where you can.

The opt-out also has limits that matter. By Google's description, it covers Search's generative features, not every Google AI product. And it is a choice to step away from a surface, not compensation for content that was used before.

What we know vs. what we're inferring

Known (sourced): the September 30, 2026 dismissal by Judge Mehta; the "expectation is not an agreement" reasoning; the grounds summarised above; the CMA's June 3, 2026 conduct requirements and nine-month compliance window; Google's toggle and its stated worldwide rollout as of August 31, 2026.

Inferred (our analysis): that the appeal clock runs to about October 30, 2026, assuming judgment was entered on September 30 and the standard 30-day federal rule applies; that the CMA's nine-month window ends around early March 2027; and that the opt-out is mainly useful to sites whose content AI answers substitute for. Neither plaintiff had announced an appeal in the coverage we reviewed. We could not read the full opinion directly, so its quotations here come from the outlets linked.

What to watch next

• By October 30, 2026 (Friday): whether Penske or Chegg files a notice of appeal to the D.C. Circuit. Federal filing days end at midnight in the court's time zone, which is 12:00 a.m. ET, or 1:00 a.m. UTC-3, on October 31 (our calculation).
• Around early December 2026: Google's first six-monthly compliance report to the CMA is due within the first year of the June 3 requirements (exact date not confirmed).
• Around March 3, 2027: the end of the CMA's nine-month implementation window (our calculation from June 3, 2026).
