A class action lawsuit has been filed against Microsoft Corporation and certain senior executives for securities fraud, alleging the company misled investors about the functionality and adoption of its AI chatbot Copilot. The suit, brought by Bleichmar Fonti & Auld LLP, claims that Microsoft touted Copilot's best-in-class capabilities and surging Azure-related revenue while the product actually suffered from severe functionality issues that caused user adoption to decline. On January 28, 2026, Microsoft announced disappointing second-quarter 2026 financial results and revealed that Microsoft 365 Copilot premium customers totaled only 15 million, materially below analyst estimates, causing the stock to drop 10% from $481.63 to $433.50 per share. The complaint further cites a February 3, 2026 Wall Street Journal report detailing challenges and interoperability problems that frustrated users and led to market share losses. Investors have until August 11, 2026 to seek lead plaintiff appointment in the case pending in the U.S. District Court for the Western District of Washington.
