Tech giant Microsoft hits $4 trillion market capitalization following stellar earnings report
Microsoft's Azure cloud computing business is reporting booming sales, with the company's stock more than doubling since ChatGPT's late-2022 debut. This growth can be attributed to Microsoft's strategic investments in AI and cloud infrastructure.
In 2025, Microsoft's capital expenditure (capex) reached around $20 billion in the second quarter, with expectations to hold elevated levels between $16 billion and $17 billion in Q4 to support AI data center expansion and cloud infrastructure growth. For the full fiscal year 2025, capital expenditures rose sharply by 45% from $44.48 billion to $64.55 billion. Analysts project some moderation in capex growth in FY 2026, though spending remains high given the strategic focus on AI and cloud.
This massive capex aligns with Microsoft's broader AI investments, including a $13 billion stake in OpenAI (not yet directly generating revenue). The company saw strong cloud revenue growth of 20% year-over-year to $42.4 billion and 33% growth in Azure revenue. The high demand for AI and cloud services has driven gross profits up 14% year-on-year to $49.8 billion, underscoring AI's key role in growth.
Microsoft's AI investments and cloud infrastructure spending contribute to several growth drivers:
- Cloud and AI revenue momentum: Cloud revenue up 20% year-over-year, driven by Azure and AI services.
- Operating income of $32 billion despite a 5% increase in operating expenses due to AI R&D.
- Expansion of gaming and enterprise offerings augmenting revenue diversification.
- Analysts forecast FY 2026 revenue growth of about 14.3% to $322 billion, supported by robust operating cash flow expected around $170 billion thanks to these investments.
Microsoft's strategic focus on AI and cloud is part of a broader industry trend. Top hyperscale cloud providers (Amazon, Alphabet, Meta, and Microsoft) are collectively driving 77% of global cloud capex growth, spending $359 billion in 2025 (57% increase) and expected $454 billion in 2026 (26% increase).
The stock's rally for Microsoft has been further boosted by its focus on AI investments and workforce trimming. Microsoft's strong earnings have demonstrated resilience against sweeping US tariffs, suggesting its books have not yet been affected by the levies.
Wall Street's confidence in Microsoft has grown following back-to-back record revenues since September 2022. Shares of Microsoft were up 4.5% at $536.47, surpassing $4 trillion in market valuation on Thursday.
As Microsoft continues to invest in AI and cloud infrastructure, it is poised to maintain its competitive positioning and leadership in the cloud and AI markets.
