Nvidia shares fell 13 per cent in opening Wall Street trading on Thursday, 12 November 2026, after co-founder Jensen Huang resigned as chief executive. The sell-off pushed the chipmaker’s valuation below $4 trillion for the first time since July 2025, wiping roughly $800 billion off its market worth this week. Investors quickly priced in severe leadership risk at the heart of the global artificial intelligence boom, pushing rival chipmakers like AMD and Broadcom sharply higher.
Personal indiscretions turned into an acute corporate governance and national security crisis that even a near-monopoly on artificial intelligence processors could not survive. American intelligence officials recently flagged Huang’s extramarital relationship with Alice Huang, an executive at Singapore-based Megaspeed linked to China’s Ministry of State Security. A second revelation detailing an affair with Kimberly Powell, a senior vice-president reporting directly to him, shattered remaining boardroom support.
Nvidia’s directors moved swiftly to contain the fallout by naming longtime chief financial officer Colette Kress as interim boss. The board also appointed former Synopsys head Harvey Jones as its first-ever independent chair to overhaul corporate oversight. Yet handing daily control to a finance chief highlights a glaring lack of technical succession planning at a company where Huang famously managed sixty direct reports himself.

Washington’s strict semiconductor export controls now face intense scrutiny from lawmakers and trade officials. Federal investigators suspect Megaspeed, which bought billions of dollars in Nvidia hardware, of diverting restricted processors straight to Chinese entities. Beijing flatly denied the espionage claims, while Megaspeed pledged full cooperation with American authorities to clear its name.
Market reaction shows how tightly Nvidia’s towering valuation depended on its founder’s personal authority and engineering vision. The share price drop compressed the firm’s forward earnings multiple to roughly twelve times, marking its lowest valuation level since 2012. Traders clearly fear that an abrupt leadership vacuum could slow product execution just as competitors race to chip away at Nvidia’s market share.
Demand for artificial intelligence computing power still exceeds global supply, meaning the underlying business remains fundamentally profitable. Even so, an independent investigation led by law firm Wachtell, Lipton, Rosen & Katz continues to probe whether company secrets or national security suffered real harm. Restoring investor confidence will require finding a permanent technical leader capable of navigating both fierce market competition and Washington’s geopolitical minefields.
