Microsoft Heads for Worst Month Since 2000 as AI Capex Worries Drive $570 Billion Rout
- Microsoft has lost more than $570B of market value in June 2026, putting the stock on track for a monthly decline exceeding 21% — its worst since the dot-com bust (Bloomberg).
- Investors are repricing MSFT around roughly $190B of 2026 AI-infrastructure capex and the uncertain timeline for returns, accelerating the rotation out of megacap tech.
- The slide is the largest single-stock drag in this month's tech-led selloff, even as the Nasdaq staged a relief rally on June 29.
