The $4 trillion club has a second member.
Microsoft shares climbed more than 5% Thursday following a better-than-expected earnings report, lifting the software giant’s market cap above the $4 trillion mark.
The company joined chipmaker Nvidia, which hit $4 trillion for the first time earlier this month.
Microsoft reported 18% revenue growth, its fastest rate of expansion in over three years, driven by its Azure cloud computing business. Microsoft disclosed Azure revenue in dollars for the first time, and said sales from Azure and other cloud services exceeded $75 billion in fiscal 2025, up 34% from the prior year.
Nvidia and Microsoft, two of the biggest beneficiaries of the artificial intelligence boom, have zoomed past Apple on the market cap leaderboard.
Apple is third at about $3.2 trillion, with its stock having fallen 17% this year as investors worry that the iPhone maker is getting left behind in AI. Apple reports quarterly results after the bell on Thursday.
Among tech’s megacaps, Nvidia has been the best performer in 2025, up 33%. The chipmaker’s graphics processing units (GPUs) are the backbone of the large language models being developed by Microsoft, OpenAI, Google, Meta and others, and they’re filling up data centers being built by those same companies.
Nvidia is scheduled to report results in late August.
