Microsoft Stock Soars as $190 Billion AI Capex Plan Takes Shape

Microsoft's stock price has broken out above its 0.618 Fibonacci retracement at $433.53, fueled by strong bullish candles and a Relative Strength Index (RSI) nearing 79. The company's Q3 FY2026 earnings report already provides the fundamental context: revenue of $61.9 billion increased 13% year-over-year, with Azure revenue rising 31%. This growth is largely driven by the popularity of AI-based services, with over 80% of Fortune 500 companies adopting Azure AI services.

The company's capital expenditures for calendar year 2026 are expected to reach $190 billion, mostly spent on data centers, GPUs, and AI infrastructure. While this may seem like a risky bet, Microsoft's management is confident that demand for AI services will continue to grow. In fact, they claim that current AI demand exceeds Azure's ability to supply AI services on GPU-backed compute.

One of the key drivers of Azure's growth is its Copilot monetization layer. Copilot is an AI assistant integrated into Microsoft 365, GitHub, and other areas of the Microsoft ecosystem. The commercial version adds about $30 per user per month to enterprise MSFT 365 software, with hundreds of millions of commercial Office users providing a potential revenue stream.

Microsoft's Build 2026 conference today is expected to announce the next generation of Copilot agents, which will be capable of taking autonomous multi-step actions rather than just answering questions. This represents higher-end products with a higher price point, and could potentially add billions of high-margin revenue per year to Microsoft's top line.

From a technical perspective, MSFT has broken out above the 0.236 Fibonacci level at $457.49, with price targets set at $472.29 and $479.97. A sustained close below $448.32 would invalidate the short-term bullish structure.
