Alphabet Inc., the parent company of Google, is facing scrutiny over potential violations of U.S. securities laws after reports that delays in the development of its advanced artificial intelligence model, Gemini 3.5 Pro, contributed to a sharp decline in the company’s share price. The Law Offices of Howard G. Smith has announced an investigation to determine whether Alphabet failed to disclose material information to investors in a timely manner, potentially causing financial losses.
The investigation follows a media report alleging that Gemini 3.5 Pro had fallen several months behind schedule due to coding challenges and weaker-than-expected training results. After the report became public, Alphabet’s shares fell approximately 4.4% on July 16, 2026, resulting in significant losses for investors and a substantial decline in the company’s market value.
According to the Law Offices of Howard G. Smith, the investigation aims to determine whether Alphabet violated federal securities laws by failing to adequately inform investors about material developments that could have influenced their investment decisions. The firm has invited investors who purchased Alphabet shares during the relevant period and suffered financial losses to contact it regarding potential legal claims. At this stage, the investigation is preliminary, and no court has determined that the company engaged in any wrongdoing.
Several other U.S. law firms have also announced similar investigations into possible securities fraud claims arising from the same reports. These firms are examining whether Alphabet provided investors with sufficient and timely disclosures regarding the project’s progress, technical challenges and potential business risks.
Gemini 3.5 Pro is regarded as one of Google’s next-generation artificial intelligence models and is being developed at a time when competition among major technology companies in generative AI and large language models (LLMs) is intensifying. As AI has become a key driver of growth and valuation across the technology sector, delays involving major AI projects are closely monitored by investors and financial analysts.
Market analysts note that companies investing heavily in artificial intelligence are expected to provide transparent updates on development timelines, technical progress and execution risks. Significant delays or performance issues involving flagship AI initiatives can directly affect investor confidence, stock performance and broader market sentiment.
Legal experts point out that U.S. securities laws require publicly listed companies to disclose material information accurately and in a timely manner. If a company is found to have withheld significant information or made misleading statements that affected investors, it may face class-action lawsuits or other legal proceedings. However, any determination of liability depends on the outcome of regulatory investigations and judicial proceedings.
Alphabet has not issued a detailed public response regarding the ongoing investigations. Should any formal legal action be initiated, the company will have an opportunity to present its position before the appropriate legal authorities. Analysts believe the matter extends beyond Alphabet alone and highlights the growing importance of corporate governance, transparency and risk disclosure for technology companies operating in the rapidly evolving artificial intelligence sector.
