On September 14, 2026, multiple national shareholder rights law firms announced ongoing investigations into Alphabet Inc. for possible violations of federal securities laws. The firms seek investors who may have incurred losses.

The investigations follow events from July 2026. Reports indicated Google was months behind schedule on its flagship AI model, Gemini 3.5 Pro. A subsequent earnings report revealed a significant increase in planned capital expenditures. The report also showed negative free cash flow for the quarter. These July events led to notable drops in Alphabet's stock price.
