Nov. 10, 2026 — Microsoft overtook Nvidia as the world’s second-most valuable company on Tuesday, as the artificial intelligence chipmaker’s shares continued to decline amid uncertainty surrounding the AI market and an investigation into whether CEO Jensen Huang was targeted by a foreign intelligence operation.
The shift marks the first time Microsoft has held the second-place ranking since June 2025, highlighting the growing pressure on Nvidia as investors reassess the outlook for artificial intelligence investments and the company’s leadership risks.
Microsoft shares were down 0.4% at $543.25, while Nvidia fell more than 6% to approximately $167.11.
Nvidia Shares Come Under Pressure
Nvidia’s latest decline reflects growing investor concerns about the company’s exposure to the rapidly changing AI market.
The chipmaker has faced increasing uncertainty following an investigation into allegations involving CEO Jensen Huang and a Chinese businesswoman reportedly connected to foreign intelligence activities.
The investigation has raised questions about Nvidia’s corporate governance, potential regulatory exposure and dependence on Huang’s leadership.
Nvidia’s position at the center of the global AI boom has made its stock particularly sensitive to changes in investor confidence.
AI Investment Uncertainty Weighs on Nvidia
Beyond the investigation, investors are also reassessing whether the enormous investments being made in artificial intelligence infrastructure will generate sufficient long-term returns.
Nvidia has benefited significantly from demand for advanced processors used in AI data centers, making it one of the biggest winners of the technology investment boom.
However, growing concerns about infrastructure spending, regulatory restrictions and geopolitical risks have increased uncertainty surrounding the sector.
The latest developments have raised questions about whether the pressure will remain specific to Nvidia or extend across the broader AI infrastructure industry.
Microsoft Regains Second-Place Market Ranking
Microsoft’s move ahead of Nvidia reflects the contrasting performance of the two technology giants as investors navigate uncertainty in the AI market.
Although Microsoft shares also declined slightly on Tuesday, Nvidia’s sharper losses were enough to change their positions in the global market capitalization rankings.
The development marks a notable shift in the technology sector, where Nvidia’s rapid rise during the AI boom had made it one of the world’s most valuable companies.
Investors will now be watching whether Nvidia can stabilize its share price as the company addresses the concerns surrounding its leadership and the broader outlook for AI spending.
For Microsoft, the change represents a return to the second position among the world’s most valuable companies, while Nvidia faces a more challenging period as questions about its business risks and market expectations continue to grow.
