Under Judge Mehta’s ruling, Google is required to hand over some search results to rival companies. Sharing its data, which has been the backbone of its search engine, could help Microsoft, OpenAI, Perplexity and others improve their search products.

Alphabet’s Google does not have to sell its Chrome web browser but must share some of its search and other data with competitors, a federal judge decided in the Justice Department’s landmark case against the search giant.

Judge Amit Mehta found Google guilty of illegally monopolizing search, and then allowed the company to keep doing it.
