New York | A securities fraud class action lawsuit has been filed against Microsoft Corporation and certain of its senior executives on behalf of investors, alleging that the company made misleading statements regarding its AI chatbot Copilot and cloud computing platform Azure, resulting in investor losses after a sharp decline in Microsoft’s share price.
The lawsuit has been filed in the U.S. District Court for the Western District of Washington. According to the complaint, Microsoft allegedly promoted Copilot’s capabilities and widespread adoption during the relevant period, leading investors to believe that the product was driving strong growth in Azure-related revenue.

The plaintiffs allege that, in reality, Copilot suffered from significant functionality issues that negatively affected user adoption and posed risks to Azure’s growth. The lawsuit claims that these alleged problems were not disclosed to investors in a timely manner.
According to the complaint, Microsoft announced its second-quarter fiscal 2026 financial results on January 28, 2026, revealing that Azure’s growth had slowed more than expected. The company also disclosed that Microsoft 365 Copilot had approximately 15 million premium customers, a figure that was reportedly below analysts’ expectations. Following the announcement, Microsoft’s share price declined by approximately 10% in a single trading session.
The lawsuit further cites a subsequent media report that allegedly highlighted Copilot’s functionality challenges, brand positioning issues and interoperability problems, which were said to have affected the product’s market share.
The case has been brought under the relevant provisions of the U.S. Securities Exchange Act of 1934. Eligible investors have until August 11, 2026, to apply to the court for appointment as the lead plaintiff in the class action.
The matter is currently pending before the court. The allegations contained in the lawsuit represent the claims of the plaintiffs, and no court has reached a final determination on their merits. Any legal liability of Microsoft or its executives will be determined only after the judicial process is completed.
