Microsoft overtakes Nvidia in market value, first time since June 2025

Microsoft's market value has climbed back above Nvidia's for the first time since June 2025. The two had been trading places all year at the very top of the tech pile: a November 9-10, 2026 snapshot put Nvidia at roughly $4.09 trillion and Microsoft at roughly $4.03 trillion — a gap narrow enough that one strong session flips the order. Neither is actually No. 1. Apple led that same snapshot at approximately $5.07 trillion, leaving Microsoft and Nvidia scrapping over second place.

Microsoft's recent ride has been wild. On July 30, 2026 it added about $450 billion in market value in a single day, its largest one-day gain on record, after upbeat guidance on its Azure cloud business. It then slipped below the $4 trillion mark in June 2026, clawed its way back above it in October 2026, and still trailed Nvidia — until now.

Nvidia's turn at the front started in June 2025, powered by surging demand for its AI accelerators, the specialized chips that train and run large AI models. Hyperscalers — the giant cloud providers running massive data center networks — are its most important buyers. Microsoft is one of them, which makes the rivalry a touch awkward: Nvidia built part of its lead on contracts with the very company that just edged past it.

Microsoft isn't standing still. It has been pouring money into custom silicon, designing its own chips to lean less on outside suppliers — a strategy aimed squarely at companies like Nvidia. So the tie runs both ways: Microsoft is a major Nvidia customer and, increasingly, a company trying to need Nvidia a little less.

The next moves hinge on two variables. Azure guidance has already shown it can swing Microsoft's stock by hundreds of billions of dollars in a day, so cloud updates carry real weight. On Nvidia's side, hyperscaler budgets drive a large share of its growth — and if Microsoft's in-house chips let it buy less hardware over time, that supports Microsoft's margins while squeezing the vendors it buys from today.
