Microsoft investors have 11 days to take control of a fraud lawsuit. It says the company hid trouble inside Copilot, its main artificial intelligence product.

The timing is odd. Microsoft just set a US record for market value gained in a single day. The engine behind that gain was the same product the lawsuit attacks.

The case covers anyone who bought Microsoft stock between May 1, 2025 and January 28, 2026.

Investors say Microsoft praised Copilot in public while hiding its flaws. They argue the stock traded far above what it was worth.

The suit sits in a federal court in Washington state. A police and fire pension fund from Michigan is named first.

The alleged flaws are simple ones. Confusing branding. Tools that did not work well together. Customers who tried Copilot and never paid for it.

Microsoft reported fiscal second quarter results on January 28. Revenue rose 17% to $81.3 billion. Azure grew 39%.

Investors looked past those numbers. Record capital spending worried them, and Microsoft put Copilot at just over 15 million paid seats.

The complaint puts it harder. It says Azure growth slowed suddenly and the Copilot figure landed well below what analysts had modelled.

The stock fell the next day from $481.63 to $433.50. That is $48.13 gone, or 10%.

Similar suits have followed big tech AI spending letdowns all year.

On Wednesday, Microsoft posted $90 billion in fiscal fourth quarter revenue. Azure grew 43%. Copilot seats doubled to more than 30 million.

Shares jumped over 16% on Thursday. Microsoft gained roughly $450 billion in value, the biggest one-day rise any US company has ever posted.

“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,” Nadella said in the earnings release.

The stock traded at $462.52 on Friday, up 2.53%. That is still under the $481.63 close before the January fall. The losses are real. So is the comeback, and Microsoft’s lawyers will say so loudly.

Most will not, and the few who do will likely wait years for a small cheque. August 11 is not a payday. It is the last day to ask the court to lead the case.

Anyone who bought in that window keeps the right to money later. No sign-up, no lawyer, and no fee.

The notices filling inboxes this week are adverts. Law firms send them after every big stock drop.

Microsoft will now ask a judge to throw the case out. Most suits like this die right there. The ones that survive tend to settle for a small share of the losses claimed, and that takes three years or more.

The rally makes the climb steeper. It is harder to argue investors are still out of pocket when the stock has clawed back most of the fall.

The lesson for traders is short. AI promises now carry legal risk, and that risk sits in the market’s biggest names. That matters while shares still move as one giant AI trade, and it belongs in any list of US stocks to watch in August.
