Microsoft shareholder sues to obtain internal records over alleged Copilot AI-training misconduct

What happened: A Microsoft shareholder from Washington filed a lawsuit seeking internal records related to alleged executive misconduct, including claims of insider trading, stock buybacks at inflated prices, and the use of copyrighted works to train Microsoft's AI models, specifically the Copilot coding assistant, according to Legal News Feed (22 September 2026, citing Reuters reporting on shareholder scrutiny of AI practices).

Why it matters to creators: The suit puts Microsoft's Copilot training-data practices — and their copyright implications — into a corporate-governance record fight, echoing the separate Apple shareholder derivative suit over AI-training copyright claims; investors are now treating AI data-sourcing as a material liability question.

What is not yet known: this is a records-demand suit, not a merits ruling on the copyright claims; no court has decided whether Copilot's training was infringing.
