The split that opened the morning widened by the close. Microsoft closed up 6.5% at a record $554.88 and Apple rose about 6% to an all-time high. Amazon gained about 7% and Alphabet more than 4%. During the session Bloomberg had those four and Meta on pace to add nearly $1 trillion of market value; we did not find a closing total. The Dow rose 3.03% to 53,356.12, its best day since April 9th 2025, the S&P 500 gained 1.58% to 7,688.62 and the Nasdaq 1.44% to 25,736.51.
Everything that sells into the buildout fell. Nvidia closed down 2.41% and Micron 6.41%. At midday CNBC had Iren down 11%, Nebius about 6%, Sandisk 7%, the power producer Vistra 13% and the data center contractor Comfort Systems 17%. SpaceX ended about 4% lower.
Investors are paying the spenders to spend less. One portfolio manager told Bloomberg the brakes on their spending are now being applied by the government, and analysts called Apple a defensive pick for having skipped the buildout. Goldman Sachs's AI basket had already dropped 15% in October and sat more than 24% below its peak going into the session.
The bet has a weak point: any Democratic bill still needs President Trump's signature, and the state-level limits that did pass bind the companies that need new sites far more than the ones with sites already built.
Big Tech's rally approaches $1 trillion on a bet that Democrats will restrain AI spending
