Alphabet shares fall 4% as Gemini 3.5 Pro delay cools AI expectations
Alphabet shares hit an all-time high on May 13 after rising more than 150% over the prior 12 months, but AI competition and product timing concerns have weighed on momentum. Gemini 3.5 Pro is behind schedule, and Google released Gemini 3.7 Flash without updating the timetable. After peers’ hiring and model progress chatter intensified, shares dropped about 4% on Aug. 5, erasing $186 billion in market value in a session.
