A US judge has ruled that Google may keep its popular Chrome browser but ordered the tech giant to share data obtained through its services.

Google wonât have to sell its Chrome browser, a judge in Washington has ruled, handing a rare win to Big Tech in its battle with US antitrust enforcers, but ordering Google to share data with rivals to open up competition in online search.
Google parent Alphabetâs shares were up 7.2 per cent in extended trading on Tuesday as investors cheered the judgeâs ruling, which also allows Google to keep making lucrative payments to Apple that antitrust enforcers said froze out search rivals. Apple shares rose three per cent.
US District Judge Amit Mehta also ruled Google could keep its Android operating system, which together with Chrome help drive Googleâs market-dominating online advertising business.
The ruling results from a five-year legal battle between one of the worldâs most profitable companies and the US, where antitrust regulators and lawmakers have long questioned Big Techâs market domination. Mehta ruled last year that Google holds an illegal monopoly in online search and related advertising.
But the judge approached the job of imposing remedies on Google with âhumilityâ, he wrote, pointing to competition created by artificial intelligence companies since the case began.
âHere the court is asked to gaze into a crystal ball and look to the future. Not exactly a judgeâs forte,â Mehta wrote.
While sharing data with competitors will strengthen rivals to Googleâs advertising business, not having to sell off Chrome or Android removes a major concern for investors who view them as key pieces to Googleâs overall business.
Google faces a major threat from increasingly popular AI tools including OpenAIâs popular ChatGPT chatbot, which are already eroding Googleâs dominance. If allowed to access the data Google is required to share, AI companies could bolster their development of chatbots and, in some cases, AI search engines and web browsers.
âThe money flowing into this space, and how quickly it has arrived, is astonishing,â Mehta wrote, saying AI companies are already better placed to compete with Google than any search engine developer has been in decades.
Deepak Mathivanan, an analyst for Cantor Fitzgerald, said the data-sharing requirements pose a competitive risk to Google but not right away.
âIt will take a longer period of time for consumers to also embrace these new experiences,â he said.
US antitrust enforcers are considering their next steps, Assistant Attorney General Gail Slater said on X.
Google said in a blog post it was worried data sharing âwill impact our users and their privacy, and weâre reviewing the decision closelyâ.
Google has said previously that it plans to file an appeal, which means it could take years before the company is required to act on the ruling. The case is likely to end up in the Supreme Court.
âJudge Mehta is aware that the Supreme Court is the likely final destination for the case, and he has chosen remedies that stand a good chance of acceptance by the Court,â said William Kovacic, director of the competition law centre at George Washington University.
The ruling was also a relief for Apple and other device and Web browser makers, whom Mehta said can continue to receive advertising revenue-sharing payments from Google for searches on their devices. Google pays Apple $US20 billion ($A31 billion) annually, Morgan Stanley analysts said last year.
Banning the payments is even less necessary amid the rise of AI, Mehta wrote, where products such as OpenAIâs ChatGPT âpose a threat to the primacy of traditional internet searchâ.
The ruling also made it easier for device makers and others who set Google search as a default to load apps created by Googleâs rivals, by barring Google from entering exclusive contracts.
Google itself had proposed loosening those agreements, and its most recent deals with device makers Samsung Electronics and Motorola and wireless carriers AT&T and Verizon allow them to load rival search offerings.
