Microsoft Loses Over $570 Billion in Market Cap in June, Worst Single Month Since 2000
0xBroomberg
Microsoft fell 17% in June, erasing more than $570 billion in market value — its worst month since December 2000 — as the market priced in twin risks: AI spending burning cash too fast, and AI potentially disrupting Microsoft's own products.
How far did it fall, and where does it sit now?
Microsoft dropped 17% in June, shedding over $570 billion in market cap and briefly hitting its lowest closing price since 2023.
On a forward-12-month earnings basis, its P/E ratio fell to roughly 19× — below the S&P 500's 20× and far under its own ten-year average of 27×.
This means → the market is now valuing Microsoft below the broad index average, something almost unheard of for a company that has traded at a premium for a decade.
What exactly is the market worried about?
Two pressures are squeezing at once: AI capex is too high (projected at $190 billion through December, above Wall Street estimates) + AI may cannibalize Microsoft's own products (whether Word, Excel, and other legacy software will be displaced by AI remains unresolved).
Azure cloud growth missed expectations. Stifel analyst Brad Reback cut his target from $415 to $400, citing accelerating capex compressing Azure gross margins — the profit Microsoft keeps on each dollar of cloud revenue.
In plain terms = Microsoft is spending aggressively to build AI infrastructure but hasn't yet proven these investments will pay back fast enough. The market's patience is running out.
Why does the debt-funded buildout add extra unease?
Cresset chief strategist Jack Ablin noted that Microsoft is borrowing heavily to fund infrastructure. This reflects a cash reserve that can't cover the full buildout cycle on its own.
This means → if AI monetization lags, Microsoft faces a double squeeze: profits eroded by capex *and* rising debt-servicing costs.
Ablin summed up the market's mood: "Valuations are quite low, but investors are in sell first, ask questions later mode."
Michael Burry stepped in — how strong a signal is that?
"Big Short" investor Michael Burry disclosed on Substack that he bought Microsoft call options struck just above $700, expiring in 2028 — an extremely bullish bet, effectively wagering the stock nearly doubles within three years.
The news drove a 5.7% Friday rally to $372.97, Microsoft's biggest single-day gain since May 2025.
In plain terms = Burry's fame moved short-term sentiment, but one options trade is not a fundamental reversal. The real test still lies ahead.
Why are valuation and growth expectations at odds?
Analysts on average expect Microsoft's current-fiscal-year revenue growth at 17% — the fastest since 2022 — accelerating to 18% in FY2028 and 20% in FY2029.
Yet the P/E sits at 19×, far below the ten-year mean of 27×. Growth expectations are accelerating while the valuation is compressing — a clear divergence.
This means → whether the next quarterly report (due imminently) can prove AI spending is converting into profit will determine if the buy-the-dip thesis holds. That is the single most critical checkpoint right now.
