Nvidia Falls Again, Shedding $430B in Market Value Over Two Days

The scale of the drawdown matters less than the company-specific turn: a shareholder suit and a board-initiated independent investigation shift the story from AI demand to governance and disclosure risk. That affects Nvidia's own investor base and, by extension, the wider AI-linked complex that has traded on its momentum, since Microsoft's brief move into second place shows how quickly relative rankings can reprice. The open question is whether the legal and board scrutiny stays contained or becomes the narrative that outlasts the selloff.
