Microsoft Faces Class-Action Lawsuit Over Alleged Copilot Misstatements

A class-action lawsuit has been filed against Microsoft Corporation (NASDAQ: MSFT) over alleged misstatements about its Copilot family of products. The suit claims that Microsoft made false and/or misleading statements throughout a certain period, which led to investors suffering damages.

The Rosen Law Firm reminds purchasers of common stock between May 1, 2025 and January 28, 2026, inclusive (the “Class Period”), of the important August 11, 2026 lead plaintiff deadline. Investors who purchased Microsoft common stock during this period may be entitled to compensation without payment of any out-of-pocket fees or costs through a contingency fee arrangement.

The lawsuit alleges that defendants made false and/or misleading statements and/or failed to disclose several issues with the Copilot family of products, including brand positioning, user experience, usage, data siloing, computational capacity, organizational, and interoperability problems. The suit also claims that Microsoft's flagship proprietary AI model ranked well below competitors on benchmark tests.
