Guess which US stock just joined Nvidia in hitting a US$4 trillion market cap

It becomes only the second company to do so after Nvidia. Here's what's powering its historic ascent.

After a blockbuster earnings report, shares in Microsoft Corp (NASDAQ: MSFT) surged 8% in after-hours trading, pushing its market capitalisation above US$4 trillion.

Joining the US$4 trillion club is a massive feat, which makes Microsoft the second company to join this club, alongside Nvidia Corp (NASDAQ: NVDA).

US$4 trillion is approximately A$6.22 trillion, making Microsoft worth almost twice as much as all the companies listed on the ASX!

What could possibly make one company worth so much? Relentless execution and growth at scale in cloud computing and artificial intelligence.

Microsoft's AI engine hits overdrive

For the June quarter, Microsoft delivered:

  • Revenue of US$76.4 billion (up 18%)
  • Net income of US$27.2 billion (up 24%)
  • Diluted EPS of US$3.65 (up 24%)

Azure cloud revenue surged 39%, as Microsoft revealed that Azure alone generated over US$75 billion in annual revenue. Its broader cloud business brought in US$46.7 billion for the quarter and a record US$168 billion for the year.

CEO Satya Nadella captured the moment on the earnings call:

We are going through a generational tech shift with AI… and we continue to scale our own datacenter capacity faster than any other competitor.

AI adoption is showing up across Microsoft's ecosystem with GitHub Copilot now being used by 90% of the Fortune 100, and the overall family of Copilot Apps surpassing 100 million monthly active users.

To support surging demand, Microsoft spent US$24.2 billion in capital expenditures this quarter, and the company plans to spend over US$30 billion next quarter to expand its infrastructure.

Foolish Takeaway

You've got to hand it to Satya Nadella. What we are witnessing here is superb execution and growth at scale. It doesn't happen by luck or chance.

Microsoft's rise to a US$4 trillion valuation isn't about hype; it's about decades of platform-building and seizing the moment when generational technologies like cloud computing and AI rise.

From the desktop to the data centre, Microsoft has positioned itself at the centre of the AI economy, and it's being valued accordingly.

In a world increasingly shaped by intelligent systems, Microsoft isn't just along for the ride. It's building the rails.
