Microsoft Shares Fall Roughly 17% in June on AI Spending Worries

Microsoft (MSFT) shares fell roughly 17% in June 2026 alone, wiping out about $570 billion in market value. The stock is down more than 24% year-to-date, approaching its worst year-to-date performance since the dot-com era of 2000. The selloff stems mainly from investor anxiety over massive AI-related capital expenditures (capex). While Azure-driven AI demand remains robust, concerns over the lag before that spending generates revenue, and over margin pressure, have spread; at one point the stock fell more than 23% from a 52-week high near $555.
