Alphabet Faces Securities Class Action Over Alleged Gemini 3.5 Pro AI Launch Delays

Law firms are reminding Alphabet Inc. investors of upcoming deadlines, cited as November 30 or December 1, 2026, to seek lead plaintiff status in a securities class action. The lawsuit alleges Alphabet misled investors by promising a June 2026 launch for its Gemini 3.5 Pro AI model while concealing disappointing training outcomes and coding challenges. Disclosures began July 16, 2026, when reports revealed the model was months behind schedule, sending Class A shares down 4.4%, or $16.46, to $354.46. Subsequent July 22 disclosures of $5.9 billion in negative free cash flow and increased capital expenditure triggered a further 7.13% drop.
