Nvidia shares plunge as chipmaker investigates CEO over espionage allegations

Nvidia's shares tumbled more than 6% during Frankfurt trading, continuing a steep selloff that began last week and pushing the stock to its lowest levels in several months. The latest decline reflects growing investor concerns following reports that the company has initiated an internal probe into Chief Executive Officer Jensen Huang related to espionage allegations.

The investigation represents a significant development for the world's most valuable chipmaker, which has faced intense scrutiny in recent months over geopolitical tensions and export regulations affecting its semiconductor business. The nature of the specific allegations against Huang remains unclear, though the probe underscores mounting pressures on Nvidia as governments worldwide tighten oversight of advanced chip exports and foreign investments in the technology sector.

The stock's weakness also reflects broader market anxiety about the artificial intelligence sector, where Nvidia has been a dominant player. Investors have grown increasingly concerned about regulatory risks and competitive threats to the company's market position. The multi-month lows suggest that confidence among shareholders has been substantially shaken by recent developments surrounding the company's leadership and governance.
