- The lawsuit was filed on October 2, 2026, in federal court in San Jose.

What the lawsuit alleges
The case, Stewart v. Alphabet Inc. et al., was filed on October 2, 2026, in the U.S. District Court for the Northern District of California, San Jose. It covers investors who purchased or otherwise acquired Alphabet securities between May 19, 2026 and July 16, 2026.
According to the complaint, defendants made materially false or misleading statements and failed to disclose adverse facts about Alphabet’s business, operations and prospects. The allegations include that Gemini 3.5 Pro was producing disappointing training results, that its launch would therefore be significantly delayed, and that positive statements about Alphabet lacked a reasonable basis.
The complaint’s claims have not been established in court, and Glancy said that no class has been certified in the case.
Share price moves cited in the complaint
The complaint points to two market reactions. On July 16, 2026, Bloomberg reported that Google was months behind schedule on delivering Gemini 3.5 Pro, described in the release as its most powerful flagship AI model. Alphabet’s stock price fell $16.40, or 4.4%, to close at $353.81 that day.
On July 22, Alphabet released its second quarter 2026 financial results. The company announced expected full year 2026 capital expenditures of $195 billion to $205 billion and reported negative free cash flow of $5.9 billion for the quarter. It also said that supply constraints would lead it to expand its use of third-party capacity in the third quarter as a bridging strategy, creating modest near-term margin pressure.
Alphabet’s stock price fell another $24.40, or 7.13%, to close at $317.69 on July 23, according to the release.
What investors can do
Investors who want to serve as lead plaintiff must move the court by December 1, 2026. The lead plaintiff is the investor, or group of investors, appointed to represent class members and oversee the case. Under the Private Securities Litigation Reform Act, courts generally presume that the movant with the largest financial interest is the most adequate lead plaintiff.
Investors do not have to become lead plaintiff to potentially share in a future recovery. They may take no action and remain absent class members, and they may retain counsel of their choice. Glancy said it represents investors on a contingency fee basis, with fees and litigation expenses paid only from a recovery, if one is obtained, and subject to court approval.
The firm said eligible investors can submit loss information through its Alphabet case page, email [email protected], or call 310-201-9150, with a toll-free number of 888-773-9224. Prior results do not guarantee a similar outcome.
