Alphabet’s Google has filed an appeal against a US federal court ruling that found it illegally maintained a monopoly in online search and search advertising, while also asking the judge to pause an order forcing it to share key search data with rivals, including AI firms such as ChatGPT-maker OpenAI. The company argues that handing over this information before the appeal is decided would expose trade secrets, endanger user privacy, and unfairly benefit competitors.
The Google search monopoly appeal centers on a 2024 decision by US District Judge Amit Mehta in Washington, who concluded that Google used unlawful tactics to keep its dominant position in general search services and search text advertising. The court found that Google’s powerful market share—about 90 percent in general search and roughly 95 percent of search text ads on smartphones—was reinforced by multibillion‑dollar distribution deals that shut out rivals.
How the antitrust fight began
The search case began in 2020, when the US Justice Department and a group of states sued Google during Donald Trump’s first term, accusing the company of illegally monopolizing online search through restrictive contracts. The case went to trial in the fall of 2023, making it one of the most closely watched antitrust battles in the technology industry.
In August 2024, Judge Mehta ruled that Google had illegally locked up the search market by paying device makers and browser companies, including Apple and Android phone manufacturers such as Samsung, to set Google as the default search engine. The judge found that these exclusive or near‑exclusive default deals, which cost Google more than 20 billion dollars a year, made it “financially impractical” for partners to switch to competing search providers.
After a second, remedies-focused trial in spring 2025, the court rejected the government’s most aggressive proposals, including demands that Google be forced to sell its Chrome browser or stop all default search payments entirely. Instead, Judge Mehta opted for behavioral remedies designed to loosen Google’s grip on distribution while leaving the company structurally intact.
What the data-sharing order requires
The most controversial remedy requires Google to share some of its valuable search data and provide syndication services to qualified competitors, so they can display Google’s results under their own brands for a period of time. The order is aimed at helping smaller search engines and AI-driven services overcome what the court called a “scale gap” between their systems and Google’s enormous databases.
According to the ruling, the data-sharing mandates focus in particular on a “super query log” system known inside Google as Glue, which records detailed information about user searches and how people interact with the results. Regulators see access to this type of query and interaction data as crucial for allowing rivals to improve their own algorithms and products fast enough to compete.
At the same time, the court built in some limits to these requirements to address privacy and business concerns. Judge Mehta narrowed the information Google must share to what he viewed as most closely tied to its anticompetitive conduct and specifically excluded advertising data from the sharing obligations.
Beyond data, the ruling also changes how Google can buy and keep default positions on devices and browsers. Google can still pay to be the default search engine and to preload apps, including its Gemini AI chatbot, but those contracts must now be limited to one year and regularly rebid, giving other providers more chances to compete for those placements.
Why Google wants the order paused
Google’s latest filings do not ask the court to pause all the remedies; instead, the company is focused on blocking the immediate enforcement of data-sharing and syndication requirements while its appeal moves forward. Google has said it is prepared to comply with other parts of the order, such as the one‑year limit on certain contracts and new privacy and security safeguards.
In its arguments, Google contends that being forced to turn over data from its search systems to competitors now would risk exposing trade secrets, with no way to “unring the bell” if it later wins on appeal. The company also says that sharing this information “would risk Americans’ privacy and discourage competitors from building their own products,” ultimately threatening the kind of innovation that keeps US technology in a leading position.
Google further argues that Judge Mehta’s August 2024 liability decision misread how people use online search. In a public statement, Lee‑Anne Mulholland, Google’s vice president of regulatory affairs, said the ruling “ignored the reality that people use Google because they want to, not because they’re forced to,” and failed to recognize the “rapid pace of innovation and intense competition” the company faces from established firms and well-funded startups.
The company points to testimony from browser makers like Apple and Mozilla, who told the court that they choose Google as the default because they believe it delivers the best experience for users. Google also highlights growing competition from generative AI services and new search tools, including those run by companies such as OpenAI, which the data-sharing mandate is designed to benefit.
What comes next in the legal fight
Google has filed a formal notice of appeal to a federal appellate court, challenging both Judge Mehta’s finding that it holds illegal monopolies and the specific remedies he imposed. This step opens the door to what could be years of additional litigation over the future shape of the search market and the limits of antitrust remedies involving data.
While that appeal proceeds, Judge Mehta must decide whether to grant Google’s request to put the data-sharing and syndication requirements on hold. Google’s filings stress that once sensitive internal data is handed to rivals, the company cannot fully recover from the competitive and privacy harms if the order is later overturned.
US antitrust enforcers also face their own decision point. The Justice Department and the coalition of states that brought the case have until early February to decide whether they will appeal the judge’s refusal to impose stronger structural remedies, such as forcing Google to divest Chrome or more sharply limiting its default search payments.
For now, Google remains under a set of behavioral rules that restrict the length and design of its default search and app preload deals, even as it fights to avoid opening its data vaults to competitors. The coming months will determine whether the courts see data-sharing as a necessary tool to curb a search monopoly or an overreach that threatens privacy and innovation.
