| Key Points: – Microsoft surpasses $4 trillion in market cap after strong earnings and $75B Azure revenue. – Azure’s 34% growth highlights Microsoft’s central role in cloud and AI. – Tech rally continues as Nvidia, Meta, and Microsoft drive markets to new highs. |
Microsoft has officially joined Nvidia in the exclusive $4 trillion market cap club, marking a historic milestone for the software giant and underlining the tech sector’s relentless momentum in 2025. Shares surged over 5% following a robust earnings report, which included impressive revenue growth and a major new disclosure: Azure, Microsoft’s cloud platform, generated more than $75 billion in annual revenue—a 34% jump year-over-year.
This leap not only reflects the growing dominance of cloud computing, but also Microsoft’s deepening foothold in artificial intelligence. Azure has become the backbone for countless AI tools and large language models developed by Microsoft, OpenAI, and other industry titans. It’s the first time Microsoft has reported Azure’s revenue in dollar terms, a move that underscores confidence in its scale and transparency.
Microsoft now joins Nvidia, which crossed the $4 trillion threshold earlier this month, as the top two performers on the tech leaderboard. The rise of both companies has displaced Apple from its long-standing top spot. Apple currently holds a market cap around $3.2 trillion, weighed down by concerns that it’s lagging in AI innovation—a stark contrast to the explosive growth seen at Microsoft and Nvidia.
The earnings report revealed Microsoft’s fastest revenue growth in over three years, up 18%, fueled largely by AI-integrated services across its ecosystem—from Azure to Copilot. This momentum helped push the Nasdaq and S&P 500 to fresh record highs, with Microsoft and Meta among the day’s biggest gainers.
Investor confidence in Microsoft is also riding high as the broader AI boom reshapes the market. Microsoft’s strategic investments and partnerships in generative AI, including its alliance with OpenAI, continue to pay dividends. The company is widely seen as a foundational player in AI infrastructure, not just through its software, but via the massive cloud computing power needed to support this new wave of intelligence-driven applications.
Meanwhile, Nvidia remains the biggest hardware beneficiary of the AI surge. Its GPUs power the vast majority of AI models and cloud-based inference engines, including those used by Microsoft. The synergy between the two companies has made them central pillars of this new technological era, where compute power and software intelligence go hand-in-hand.
The broader tech rally was also fueled by Meta, which saw its shares jump over 11% on strong earnings and guidance. The “Magnificent Seven” mega-cap tech firms continue to dominate market headlines and investor portfolios, with Microsoft and Nvidia at the forefront of this reshaping.
Looking ahead, Microsoft’s strong positioning in AI, continued cloud growth, and investor optimism could drive further gains. With tech still attracting the bulk of growth capital, and AI becoming more embedded in daily life and business, Microsoft’s $4 trillion valuation may just be the beginning of a new market era.
