rgin. – Chang warns hyperscaler moats are weakening as SpaceX enters cloud services, while MSFT investor sentiment collapsed from very bullish to bearish in four days. – Jimmy Chang, Chief Investment Officer at Rockefeller Global Family Office, used CNBC’s Closing Bell Overtime to deliver a pointed warning ahead of Big Tech earnings: the record AI CapEx cycle may already be masking an overbuild that markets have not yet learned to see. Chang argued that strong earnings are already priced in and the real risk lies in CapEx guidance tone, flagging Microsoft (NASDAQ: MSFT) as the pivotal earnings report. “Any sign of caution could lead to a rotation of money out of some of these CapEx beneficiaries,” he said
The numbers behind the concern are staggering. Microsoft told analysts on its most recent call that Q4 2026 CapEx will exceed $40 billion, with calendar-year spending pointed toward roughly $190 billion. CFO Amy Hood disclosed that roughly two-thirds of CapEx is for short-lived assets, primarily GPUs and CPUs.
That mix is what worries Chang: the depreciation clock on AI silicon runs fast, and revenue conversion lags the spend. Microsoft’s Q3 FY26 CapEx of $30.88 billion was up 84.39% year over year, funding an AI business now at a $37 billion annual run rate. Alphabet (NASDAQ: GOOGL) has guided 2026 CapEx to $180 billion to $190 billion, with Q1 spend alone hitting $35.67 billion, up 107%.
