Wall Street is trying to figure out if the AI spending reported over the last couple of days by Meta, Microsoft, Alphabet, and Amazon is a good thing or a bad thing. Amazon was up 13% post-market after it reported strong cloud revenues. But Meta lost 11.33% yesterday after it announced it would issue $30 billion in bonds to fund its plan to spend $72 billion in capital expenditures, mostly on AI and data centers. Microsoft was down another 2.9%, also because its AI spending was greater than investors had expected. Nvidia lost 2%, also.
