MSFT's $450B glow-up makes its own AI lawsuit look like yesterday's bug report 🤖

Microsoft investors have until August 11 to petition a federal court in Washington state to lead a securities fraud lawsuit alleging the company concealed flaws in its Copilot artificial intelligence product while publicly praising its performance. The proposed class action covers purchasers of Microsoft stock between May 1, 2025 and January 28, 2026, with the Michigan-based police and fire pension fund listed as the lead plaintiff. The complaint cites confusing Copilot branding, tools that did not work well together, and customers who tried the product and never paid for it, according to court filings.

The lawsuit tracks the January 28 fiscal second quarter report, when Microsoft posted revenue of $81.3 billion, up 17%, and Azure growth of 39%. The complaint characterises Azure growth as slowing suddenly and notes Microsoft placed Copilot at just over 15 million paid seats, below analyst models. The stock dropped from $481.63 to $433.50 the next trading day, a 10% decline of $48.13 per share.

Microsoft's fiscal fourth quarter results, reported Wednesday, showed revenue of $90 billion and Azure growth of 43%, with Copilot paid seats more than doubling to over 30 million. "This year, Azure revenue surpassed $100 billion for the first time, and Microsoft 365 Copilot reached over 30 million paid seats, reflecting the confidence customers are placing in us to power their AI transformation," Chief Executive Satya Nadella said in the earnings release. Shares rose more than 16% on Thursday, adding approximately $450 billion in market value, the largest single-day gain recorded by a U.S. company. Microsoft traded at $462.52 on Friday, up 2.53% on the day, still below the pre-January close of $481.63.

August 11 is the deadline for investors to file a motion to serve as lead plaintiff, not a payout date, and no sign-up, lawyer or fee is required to preserve the right to future recovery. Notices circulating by email are advertisements from law firms, a routine follow-up to significant share price declines. Microsoft is expected to move to dismiss the case, and securities class actions of this type are frequently dismissed at that stage, with the remainder often settling for a fraction of claimed damages after three or more years.
