AI Overviews Antitrust Suits Dismissed in Win for Google

A ruling that closes an antitrust path

Publishers who hoped antitrust law would rein in Google's AI-generated search summaries have run into a wall. US District Judge Amit Mehta of the District of Columbia dismissed separate lawsuits from education company Chegg and Penske Media Corporation, the owner of Rolling Stone, Billboard and Variety. Both accused Google of using its search dominance to power AI Overviews with their content.23 The ruling came down on Wednesday, September 30. Mehta wrote that the companies' legal theories "fail to get out of the starting gate."2

Chegg filed first, bringing an antitrust case last year over how AI Overviews were cutting into its website traffic and affiliate revenue. Penske followed with its own suit.3 Both made the same core argument: Google leaves content creators with a forced choice. Either let the AI feature absorb their material, or risk losing visibility in the search engine that sends them most of their audience.1

Expectation is not entitlement

The heart of Mehta's reasoning is a distinction between a contract and a hope. According to coverage of the decision, the judge found that the publishers' claims did not rest on any agreement with Google. They rested on an "expectation" of continued traffic.3 Android Headlines summarizes the takeaway as a finding that publishers have no legal right to search traffic. Reducing the clicks Google sends to outside sites does not, by itself, amount to an antitrust violation.1

This framing matters more than the outcome of two individual cases. Antitrust claims generally need some harm to competition, not just harm to a particular business. Mehta's ruling suggests that a drop in referrals, however painful, does not meet that bar when no one was ever promised those referrals. All three outlets covering the decision agree on the basic outcome. They differ mainly in emphasis. Android Headlines stresses the "no right to traffic" principle.1 Colombia One foregrounds the content-use allegations.2 Android Authority notes this is the second major legal setback for publishers fighting AI Overviews this year.3

There is an irony in who issued the ruling. Mehta is the same jurist who presided over the government's landmark search monopoly case against Google. A finding from him that this particular theory fails carries extra weight for anyone considering a similar suit.

The numbers behind the frustration

The publishers' grievance is not imaginary, and industry data shows why they went to court. Google held 89.9% of the global search market in September 2026, and it handles more than 5 trillion searches a year.4 Its advertising business brought in $294.7 billion in 2025.4

The traffic picture for websites is far less rosy:

• About 68% of US Google searches between January and April 2026 ended without a click to any site, per SparkToro data.4
• AI Overviews appeared on roughly 48% of tracked queries by February 2026, according to BrightEdge.4
• AI Overviews reach an estimated 2.5 billion users.4

When summaries answer the question directly on the results page, the incentive to click through shrinks. For businesses like Chegg, whose model depends on people landing on their pages, that is an existential concern.

There are signs of a shifting landscape, though they offer little immediate relief. Bing has grown to 5.3% of global search and 9.9% in the US, helped by its Copilot AI integration and Edge defaults.4 Users are also turning to chatbots like ChatGPT and Perplexity.4 But rival AI tools summarize content too. They may not restore the old traffic model so much as spread the same dynamic across more platforms.

Where publishers go from here

With antitrust looking like a dead end, the realistic options narrow. The court's reasoning points publishers toward commercial licensing deals with AI companies, or toward lobbying lawmakers for new protections.1 Neither is a quick fix:

• Licensing deals favor large media groups with leverage. Smaller sites have little bargaining power.
• Legislation moves slowly and faces heavy industry lobbying.

My reading is that this decision marks a strategic turning point rather than the end of the fight. Courts appear unwilling to treat search traffic as something Google owes the web. If publishers want compensation for the content that fuels AI answers, they will likely need to win it at the negotiating table or in Congress, not through antitrust claims premised on lost clicks.

Appeals or differently framed claims, such as copyright theories, remain possible. Still, this ruling establishes a clear signal: declining traffic alone is not a legal injury Google must answer for.
