Nvidia board reportedly preparing to remove CEO Jensen Huang; shares fall 8% after hours

The significance here is governance risk, not the after-hours move itself: a reported board push against a founder-CEO at the center of the AI trade tests how much of Nvidia's valuation rests on leadership continuity. The sequence — investigation, class action, then reports of removal — matters because it suggests a process already underway rather than a single headline shock. What's worth watching is whether the board formalizes anything, since Nvidia has declined to comment and no decision has been announced; until then, the reported move remains unconfirmed and the market is pricing speculation.
