Alphabet, Pichai and Ashkenazi named in proposed securities class action over Gemini 3.5 Pro

A proposed securities class action, Stewart v. Alphabet Inc., was filed on October 2, 2026 in the U.S. District Court for the Northern District of California. It names Alphabet, CEO Sundar Pichai and CFO Anat Ashkenazi, and alleges they signaled a June launch for Gemini 3.5 Pro while not disclosing disappointing training results and a likely delay. The class covers Class A and Class C buyers from May 19 to July 16, 2026, the period ending with the 4.4% share drop after Bloomberg reported Google was months behind schedule. The allegations are unproven, and no class has been certified.
