Microsoft stock slides as data-center power costs, Trump pressure rattle AI trade
NEW YORK, Jan 14, 2026, 16:04 EST — After-hours Microsoft (MSFT.O) shares dropped 2.6% on Wednesday, deepening a retreat in mega-cap tech amid investor concerns over the escalating expenses — and political hurdles — tied to building new AI data centers. The stock lost $12.17 to close at $458.50 in late U.S. trading. Meanwhile, the Invesco QQQ fell 1.3%, and the SPDR S&P 500 ETF slipped 0.7%. Just a day earlier, Microsoft announced it would pay utility rates high enough to cover its own power costs at U.S. data centers and collaborate with local utilities to boost supply as needed.
