Microsoft overtakes Nvidia as the world’s second-most valuable firm as investors react to a reported investigation involving Nvidia CEO Jensen Huang. Multiple outlets say Nvidia shares drop more than 6%, while Microsoft’s market position improves.

The coverage links Nvidia’s fall to both AI-related concerns and uncertainty around the CEO probe. NDTV reports that AI fears and allegations about a possible foreign intelligence effort targeting Huang contribute to the rout, and notes Nvidia’s valuation slips below Microsoft’s at about $4.03 trillion. Other outlets also tie the move to the Huang probe, with Economic Times stating Microsoft’s market cap is higher than Nvidia’s for the first time since June 2025.

Financial figures highlighted across reports include Microsoft trading down about 0.4% at roughly $543.25 and Nvidia last around $167.11 after falling more than 6%. Overall, outlets largely agree on the market-cap ranking shift and the share-price direction, while differing on what details they emphasize about the probe and the specific comparison window.
