What Is the Alphabet Gemini Securities Lawsuit?
An Alphabet shareholder filed a proposed securities class action on October 2, 2026, alleging that
Google’s parent company told investors its next flagship AI model would launch in June 2026 without
disclosing that the model was struggling in training. The case is Stewart v. Alphabet Inc.,
No. 3:26-cv-11290, in the U.S. District Court for the Northern District of California. It names
Alphabet, CEO Sundar Pichai and CFO Anat Ashkenazi.
The complaint covers anyone who bought Alphabet securities from May 19 through July 16, 2026, the day
Bloomberg reported that Google was months behind on Gemini 3.5 Pro. The defendants have not yet
responded, and none of the claims has been proven.

The Statements the Complaint Challenges
The complaint focuses on two statements by Pichai:
May 19, 2026, Google I/O. Announcing Gemini 3.5 Pro for June, Pichai allegedly said, “Give us until next month to get it to you,” and that the model was “showing great improvements” over earlier versions.
June 3, 2026, special investor call. Pichai allegedly said, “Gemini 3.5 Flash is now available, and we expect Gemini 3.5 Pro will be coming in June.”
The plaintiff alleges these statements were misleading because Alphabet did not disclose that Gemini
3.5 Pro was producing disappointing training results and that its launch would be significantly
delayed. The complaint argues the statements described then-existing facts, so the legal safe harbor
for forward-looking statements should not protect them, and alternatively that they were made with
knowledge they were false. Those are the plaintiff’s arguments; a court has not ruled on them.
The Stock Drop and What Came After
According to the complaint, Bloomberg reported at about 2 p.m. Eastern on July 16, 2026 that Google
was “months behind schedule” on Gemini 3.5 Pro, and that a late-June change to the model’s training
data had produced disappointing results. That day:
Class A shares (GOOGL) fell $16.46, or 4.4%, to close at $354.46, on unusually heavy volume.
Class C shares (GOOG) fell $16.39, or 4.4%, to close at $353.58.
The complaint says the stock hit its class-period high of $390.13 on May 28, 2026. It also describes
two later events that it does not treat as part of the class period: on Alphabet’s July 22 earnings
call, Pichai said Gemini 3.5 Pro was “currently in testing” and that Alphabet had begun its largest
pretraining run yet for Gemini 4; and on September 30, the complaint says, Reuters reported that Google
no longer planned to release Gemini 3.5 Pro, the same day Google announced a limited rollout of a model
called Gemini 4 Argon.
Who Could Be Covered
The proposed class is all persons and entities that purchased or otherwise acquired Alphabet
securities between May 19, 2026 and July 16, 2026, inclusive, and were damaged by it. That includes
buyers of both share classes. Alphabet, Pichai, Ashkenazi, the company’s officers and directors, their
immediate families and entities they control are excluded. No class has been certified.
The complaint brings two claims: violations of Section 10(b) of the Securities Exchange Act and Rule
10b-5 against all defendants, and control-person liability under Section 20(a) against Pichai and
Ashkenazi. It seeks damages for class members, plus interest, costs and fees.
Lead Plaintiff Deadline and What Happens Next
Securities class actions follow the Private Securities Litigation Reform Act. Under that law, notice of
the case is published, and investors who want to serve as lead plaintiff have 60 days from that
notice to ask the court. The exact date is set by the published notice; if it ran on the October 2
filing date, the window would close around the start of December 2026. The court then appoints a lead
plaintiff and lead counsel, who usually file an amended complaint, and the defendants typically move
to dismiss. Class members do not have to seek the lead role to remain part of the proposed class.
As of October 2, the docket showed only the complaint, a proposed summons and a corporate disclosure
statement; no judge had yet been listed. This is a separate case from the
Gemini
subscription pricing lawsuit brought by consumers and the
Gemini
Gmail privacy lawsuit; this one is brought on behalf of shareholders.

Questions
Who is covered by the Alphabet Gemini securities class action?
The complaint proposes a class of all persons and entities that purchased or otherwise acquired Alphabet securities between May 19, 2026 and July 16, 2026, inclusive, and were damaged, which includes Class A shares (GOOGL) and Class C shares (GOOG). Alphabet, the individual defendants, company officers and directors and their families are excluded. No class has been certified.
What does the lawsuit say Alphabet got wrong about Gemini 3.5 Pro?
It alleges that CEO Sundar Pichai said at Google I/O on May 19, 2026, and again on a June 3 investor call, that Gemini 3.5 Pro would arrive in June, while not disclosing that its training results were disappointing and the launch would be significantly delayed. Alphabet has not responded in court, and the claims have not been proven.
How much did Alphabet stock fall?
According to the complaint, Class A shares (GOOGL) fell $16.46, or 4.4%, to close at $354.46 on July 16, 2026, after Bloomberg reported that Google was months behind schedule on Gemini 3.5 Pro. Class C shares (GOOG) fell $16.39, or 4.4%, to $353.58.
Is there an Alphabet settlement or claim form?
No. The complaint was filed October 2, 2026. There is no settlement, no certified class and no claim form. Securities class actions usually take years to resolve, and many are dismissed before any money is paid.
What is the lead plaintiff deadline?
Under the Private Securities Litigation Reform Act, investors who want to serve as lead plaintiff must ask the court within 60 days after notice of the case is first published. The exact date is set by that published notice; if it ran on the October 2, 2026 filing date, the window closes around the start of December 2026. Class members do not need to seek lead plaintiff status to remain in the class.
