Why is Microsoft Being Sued for Securities Fraud?
Microsoft has been sued for securities fraud following a significant stock drop resulting from potential violations of the federal securities laws. The decline in Microsoft’s stock price caused significant losses to investors.
Microsoft is a multinational technology company that develops software, cloud services, and devices. In recent years, Microsoft’s cloud computing platform named Azure has been Microsoft’s main growth driver. A key reason for Azure’s recent growth is Microsoft’s multi-billion-dollar investment into AI, including the development of its own generative AI chatbot named Copilot.
According to the complaint, during the relevant period, Microsoft consistently touted Copilot’s best-in-class capabilities, which purportedly drove widespread and growing user adoption. For instance, Microsoft told investors “innovation is driving our momentum,” “[a]doption is accelerating rapidly,” and that Microsoft’s Windows operating system had “best in class AI capabilities.” Copilot’s apparent success allowed Microsoft to report surging Azure-related revenue.
As alleged, in truth, Copilot suffered from severe functionality issues that caused user adoption to decline and put Microsoft’s Azure revenue at risk.
Why did Microsoft’s Stock Drop?
On January 28, 2026, Microsoft announced disappointing 2Q 2026 financial results and that Azure growth had slowed suddenly. According to Microsoft, the reason for the slower growth was computational capacity constraints as Microsoft had diverted central processing unit and graphics processing unit capacity to Copilot applications. Microsoft also allegedly revealed for the first time that the number of Microsoft 365 Copilot premium customers totaled only 15 million, materially below analyst estimates.
This news caused the price of Microsoft common stock to decline $48.13 per share, or 10%, from $481.63 per share on January 28, 2026, to $433.50 per share on January 29, 2026.
On February 3, 2026, The Wall Street Journal reported in an article titled “Microsoft’s Pivotal AI Product Is Running Into Big Problems” that severe challenges and functionality issues had plagued Copilot, causing the application to lose market share. Specifically, The Wall Street Journal reported that “[c]onfusing brand positioning and interoperability problems have frustrated users.”
