The US Department of Justice has ended its review of Google’s planned $32 billion purchase of cybersecurity firm Wiz, clearing a major obstacle for what will be the search giant's largest-ever acquisition.
The decision, made on October 24 through an “early termination” notice published by the Federal Trade Commission, effectively closes a probe that began in June into possible competition risks in the cloud security market.
Wiz chief executive Assaf Rappaport told the Wall Street Journal’s Tech Live conference that regulators had conducted a deep but efficient review, allowing the company to continue operating between the signing and closing phases.
The deal is expected to strengthen Google Cloud, led by Thomas Kurian, by adding Wiz’s artificial intelligence-driven platform for detecting and responding to cyber threats in real time.
Wiz’s technology already serves high-profile clients such as Amazon and Microsoft and will continue to support multi-cloud, on-premises and software-as-a-service environments.
A Google spokesperson said the acquisition would offer businesses and public bodies “more choice in how they protect themselves.” The transaction still requires approval in other jurisdictions, but Google anticipates completion in 2026.
The all-cash deal eclipses previous purchases by the tech giant and stands as the largest corporate acquisition announced in 2025, according to the Wall Street Journal.
Google’s parent company, Alphabet Inc (NASDAQ:GOOG), revived talks after a failed bid last year, raising its offer from $23 billion to $32 billion.
While a European Commission review remains possible, there has been no sign of formal proceedings, suggesting regulatory resistance may now be easing.
