Alphabet Faces Securities Class Action Over Gemini 3.5 Pro Delay
Levi & Korsinsky, LLP has filed a securities class action lawsuit against Alphabet Inc. on behalf of investors who purchased Alphabet securities between May 19, 2026 and July 16, 2026. The lawsuit alleges that Alphabet made materially false or misleading statements regarding the development progress and expected June 2026 launch timeline of its flagship AI model, Gemini 3.5 Pro. Specifically, the complaint claims that management failed to disclose that the model was delivering disappointing training results, leading to a significant delay. When Bloomberg reported on July 16, 2026 that the model was months behind schedule, Alphabet's stock price fell approximately 4.4%. The lead plaintiff deadline is December 1, 2026.
This securities class action against Alphabet, a major tech and advertising platform, could impact investor confidence and the company's AI product roadmap, which is increasingly intertwined with advertising technology, potentially affecting the broader AdTech ecosystem.

Alphabet Stock Falls as Gemini 3.5 Pro Delayed
Alphabet shares dropped after reports that the company has delayed the release of its flagship AI model, Gemini 3.5 Pro, which is now said to be months behind schedule. Bloomberg reported the delay, citing sources who said the model’s coding capabilities fell short of internal expectations. The model had been announced in May at Google I/O and was being used internally, but broader rollout has been postponed. Competitors including OpenAI and Meta have recently released AI models that outperform Google’s current offerings on code-generation tasks. Alphabet said it is testing 3.5 Pro and other upgraded models with partners and engaging with the U.S. government.
Gemini 3.5 Pro Delays Cause Frustration at Google
Google has repeatedly delayed the planned July release of its Gemini 3.5 Pro model after announcing new AI models at Google I/O in May 2026. Bloomberg and anonymous internal sources say the Pro build falls short of Google's internal goals, particularly on coding performance versus Anthropic and OpenAI. Google updated Gemini 3.5 Pro's training data in late June and is testing the model with selected partners while coordinating model tests and AI policies with the U.S. government. Employees cite internal governance disputes, competing teams, restricted external tool access and compute limits for slow progress and frustration. Google says roughly 75% of its code is now generated by AI and reviewed by humans, and Chief AI Architect Koray Kavukcuoglu is consolidating coding tools and loosening some internal rules.

Investors who purchased Alibaba securities during the class period may be entitled to compensation. The lead plaintiff deadline is October 5, 2026.
