Microsoft passes Nvidia in market value for first time since June 2025

Microsoft overtook Nvidia as the world's second-most valuable company on Tuesday, Reuters reported, as Nvidia shares fell more than 6% to about $167 on uncertainty over the AI outlook and an investigation into whether CEO Jensen Huang was the target of a foreign intelligence effort. Microsoft slipped 0.4% to $543.25, leaving its market cap at roughly $4.035 trillion versus Nvidia's $4.032 trillion. Nvidia has shed more than $400 billion in value since the weekend's revelations about Huang, and now trails both Apple and Microsoft.
