Microsoft hits $4 trillion market cap, second after Nvidia
Microsoft's stock surged after reporting better-than-expected earnings, pushing its market valuation above $4 trillion for the first time in its 50-year history. The company disclosed that its Azure cloud business generated over $75 billion in revenue in fiscal year 2025, driving the stock up by about 4% in after-hours trading. Microsoft becomes the second company to reach this milestone, following Nvidia, which achieved a $4 trillion valuation in early July. The earnings also highlighted Microsoft's aggressive investment in AI infrastructure, with plans to spend $30 billion in the next quarter, potentially totaling over $120 billion in the next fiscal year. CEO Satya Nadella defended prior $80 billion cloud and AI data center spending, and CFO Amy Hood confirmed the upcoming expenditure. Azure remains second to Amazon Web Services but ahead of Google Cloud in market share.
Microsoft's market cap milestone reflects strong cloud and AI infrastructure growth, underpinning the digital advertising ecosystem's reliance on Azure and AI investments.

US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
