On Friday, Microsoft (MSFT) posted its biggest single-day gain in over a year: the stock jumped 5.71% on 186 million shares traded, nearly double the daily average. The catalyst: Michael Burry, the "Big Short" investor who became a symbol of institutional skepticism, disclosed on his Substack that he had purchased long-dated LEAP call options on Microsoft with strike prices in the low $700s for December 2028. His timing was precise: the disclosure landed as MSFT touched its 52-week low, down nearly 35% from the May 2025 all-time high.
Friday's surge was dramatic, but it doesn't change the big picture. Microsoft is still down ~22% year-to-date, and June is shaping up as its worst month since 2000 (down ~21.6% month-to-date even after the bounce). The stock trades below its 50-day moving average (~$411) and its 200-day MA (~$448). Yet Burry is not alone in his optimism. Of the 56 analysts covering MSFT, 55 rate it a "Strong Buy," with a mean price target of $561, 50% above Friday's close of $372.97.
Why It Matters
The Microsoft dilemma may be the most consequential market story of 2026. On one side sits a world-class business: 18% revenue growth, powerful margins, and a cloud platform (Azure) growing at 40% annually with a quarterly run rate that crossed $54.5 billion. Commercial remaining performance obligations (RPO) surged 99% to $627 billion, a level of contracted visibility unmatched on Wall Street.
On the other side, Microsoft is now spending more than it generates. In fiscal Q3, capex hit $31.9 billion while free cash flow was just $15.8 billion, a 10% year-over-year decline. The full-year FY2026 capex guide of roughly $190 billion (up over 60% YoY, including an estimated $25 billion from memory component inflation alone) has forced a fundamental repricing of the stock.
"Investors who held Microsoft thinking it was a free-cash-flow compounder are now being asked to underwrite a capital-intensity cycle they didn't sign up for," Morningstar noted over the weekend.
What Burry's Bet Really Says
Burry, famous for betting against subprime mortgages in 2008, is not the investor you'd expect to find on the bullish side of Microsoft. He is known for chronic pessimism, large bearish positions, and a willingness to wait for extreme dislocations.
His trade: December 2028 LEAP calls with strikes in the low $700s, purchased when the stock was around $350. Because these are options rather than shares, the upfront cost was relatively low for the potential payoff. Burry told subscribers he viewed the price as making the options cheap relative to his long-term thesis.
His message is straightforward: Microsoft is cheap. At a trailing P/E of 22.2x and a forward P/E of 19.3x, the stock trades at roughly a 30% discount to its own multi-year average of 31-33x. That isn't just cheap for Microsoft, it's cheap for any high-quality technology business of this scale.
Azure and AI: The Engine and Its Risks
The real story is Azure. Microsoft's cloud platform grew 40% year-over-year in fiscal Q3, outpacing AWS (28% market share, mid-20s growth) and trailing only Google Cloud's 63% growth from a far smaller base. Microsoft Cloud as a whole posted quarterly revenue of $54.5 billion. The global cloud market crossed a $500 billion annual run rate in Q1, with the Big Three (AWS, Azure, GCP) holding a combined 63% share.
Microsoft's AI business reached a $37 billion annual run rate, up 123% year-over-year. The company is shifting its Copilot pricing model from pure per-seat licensing to consumption-based pricing, structurally expanding the addressable market beyond enterprise headcount limits.
But there's a less rosy side. Paid M365 Copilot seats reached 20 million, just 4.4% penetration of the 450 million commercial M365 base. Analysts estimate annual Copilot revenue at roughly $2.5-3.5 billion, meaningful, but a rounding error against the $190 billion capex bill. The critical question: will AI demand justify the infrastructure spend?
The $190 Billion Debate
This is the core of the story, and the reason the stock dropped 35%. Microsoft's fiscal Q2 capex guidance stunned the Street: roughly $190 billion for FY2026. The sharp increase, partially driven by memory component inflation (HBM and related), shifts Microsoft from the "cash-flow queen" category into the "infrastructure gambler" category.
Investor concerns span several dimensions:
- Industry-wide overcapacity risk: Big Tech is collectively spending $600-700 billion on AI infrastructure in 2026. If demand doesn't absorb the capacity, pricing power and margins compress.
- OpenAI concentration: Roughly 45% of the $627 billion RPO is tied to OpenAI workloads. Any disruption to that relationship, regulatory, competitive, or strategic, creates a single-point-of-failure risk.
- Securities class actions: Multiple lawsuits filed in late June allege Microsoft overstated Copilot adoption and growth prospects. Still early, but adds a legal overhang.
- Regulatory probes: An EU antitrust investigation into Azure and an Italian probe into Copilot pricing add uncertainty.
Bulls counter that the investment is strategic. "Any per user business will become a per user and usage business," CEO Satya Nadella recently said, previewing a structural expansion in how Microsoft monetizes its enterprise base.
The Bottom Line
Microsoft sits at a critical crossroads. The valuation signals, 22x trailing earnings, 15.3x EV/EBITDA, a 30% discount to its own historical average, flash green for value investors. The $627 billion RPO is an unprecedented revenue moat. Azure is growing at 40%, and the AI engine is running at full throttle.
But free cash flow is compressing, ~45% of future revenue depends on a single partnership, and the entire AI industry is playing a massive bet on demand that hasn't yet been fully proven.
As Monday's pre-market trading points to an open above $380, adding to Friday's surge, the market appears to be voting with renewed confidence. The date to watch: Microsoft's Q4 FY2026 earnings on July 29. That report, particularly the free cash flow trajectory and FY2027 capex guidance, will determine whether Burry's bet looks visionary or whether the $190 billion question has a much darker answer than today's price suggests.
