Microsoft top Nvidia's market cap for first time since June 2025

Microsoft overtook Nvidia on Tuesday to become the world’s most valuable company, for the first time since June 2025, according to the headline. Microsoft shares fell 0.4% to $543.25, while Nvidia shares dropped more than 6% to around $167.11 amid concerns about AI’s outlook and an investigation involving Nvidia CEO Jensen Huang.

What happened

Reports give conflicting rankings after Tuesday trading. One says Microsoft briefly passed Nvidia and reached $4.035 trillion in market value, versus Nvidia’s $4.03 trillion. Another says Nvidia fell more than 6% and Microsoft fell 0.4%. A corrected headline says the earlier ranking was misstated.

Global impact / market context

The reports do not agree on which company ranked higher, so the comparison is uncertain. They connect Nvidia’s share drop to concerns about AI’s outlook and an investigation involving its CEO, but give no further details. The ranking alone does not show what happens next.

What to watch

  1. Check for a clear, corrected account of the companies’ closing market values; this would settle the reported ranking.
  2. Check whether later reports describe Nvidia’s share move and the concerns about AI’s outlook; this would clarify the reported pressure on its shares.
  3. Check for further information about the investigation involving Nvidia’s CEO; the supplied report gives no details, so its significance is unclear.
