Alphabet shares faced mild pressure during the regular session as investors weighed a newly filed securities class action lawsuit alleging the company misled shareholders regarding the training results of its Gemini 3.5 Pro AI model. This negative sentiment was compounded by broader tech sector weakness, as investors remain cautious regarding high artificial intelligence capital expenditures and the potential for slowing growth. While the company continues to see robust search volumes and maintains a strong competitive position in cloud infrastructure, the stock's performance reflected these mounting legal and industry-wide headwinds.
