Microsoft’s market value passes Nvidia for the first time since June 2025

Microsoft is worth more than Nvidia again. The software giant’s market value has passed the chipmaker’s for the first time since June 2025.

The swap matters because these two companies are the most closely watched measures of how Wall Street feels about artificial intelligence. When their positions change, investors are revising their view of who profits most from the AI boom.

A rivalry measured in trillions

The gap between the two companies has been narrow for months. Data from November 9-10, 2026 put Nvidia’s market capitalization at roughly $4.09 trillion, with Microsoft close behind at roughly $4.03 trillion.

At that scale, a single strong trading session can flip the order. A sliver of a percentage point is worth tens of billions of dollars when you’re sitting on a $4 trillion valuation.

Neither company holds the top spot overall. Apple led the pack in that same snapshot, valued at approximately $5.07 trillion. Microsoft and Nvidia are effectively fighting over the silver medal, which is still a medal worth about four trillion dollars.

Microsoft’s stock has swung hard over the past several months, posting record highs and sharp pullbacks in turn.

The biggest high came on July 30, 2026. That day, Microsoft added about $450 billion in market value in a single session, its largest one-day gain on record. The jump followed upbeat guidance on Azure, the company’s cloud computing business.

The momentum didn’t last in a straight line. Microsoft slipped below the $4 trillion mark in June 2026 and only reclaimed it in October 2026. Even after getting back above that threshold, it still trailed Nvidia, until now.

How Nvidia got ahead in the first place

Nvidia’s climb past Microsoft in June 2025 came on the back of surging demand for its AI accelerators. These are the specialized chips that train and run large AI models, and Nvidia has been the dominant supplier.

Many of those buyers are hyperscalers, the giant cloud providers that operate enormous data center networks. Microsoft is one of them, which makes this rivalry a little awkward. Nvidia’s lead was built partly on contracts with the very company that just passed it.

Since June 2025, Nvidia has mostly stayed in front. There were occasional reversals tied to broader swings in tech stocks and shifts in market mood, but the general pattern held.

Microsoft has not been sitting still. It has been investing heavily in custom silicon, designing its own chips to reduce reliance on outside suppliers. That strategy is aimed squarely at cutting dependence on companies like Nvidia.

So the relationship runs in both directions. Microsoft is a major Nvidia customer and, increasingly, a company trying to need Nvidia a bit less.

What the flip says about the AI trade

Microsoft’s case rests on monetization. It sells cloud capacity through Azure, and its July rally showed how strongly investors respond when that business looks healthy.

Azure guidance has already proven it can move Microsoft’s stock by hundreds of billions of dollars in a day, so future cloud updates carry real weight.

On Nvidia’s side, demand from hyperscalers is the key variable. Those big cloud spenders are its most important customers, and their budgets drive a large share of its growth.

Microsoft’s custom chip effort is the wild card linking both stories. If in-house silicon lets Microsoft lean less on outside suppliers over time, that could support its margins while pressuring the hardware vendors it buys from today.

Microsoft’s past several months included a record single-day gain, a drop below $4 trillion, and a recovery above it. A lead built in that environment can be fragile.

Apple, meanwhile, holds a comfortable cushion at the top. Whichever of Microsoft or Nvidia ends up in second place, both still have significant ground to make up before challenging for first.
