Meta gets the love, Microsoft gets smacked


Good morning. Regular readers of this newsletter will be familiar with the term “circular deals,” and the debate about whether AI market demand is being artificially inflated by AI firms investing in each other and buying each other’s goods (take Nvidia’s investment in cloud provider CoreWeave, which buys Nvidia chips; Or Microsoft’s investment in OpenAI, which uses Microsoft’s cloud services).

Leave it to Elon Musk to take it to the next level. As Tesla revealed in its earnings on Wednesday (discussed in more detail below), the Musk-led company has purchased a $2 billion stake in xAI, the artificial intelligence startup owned by Musk. Now that’s some extreme circularity. Or is it corporate inbreeding?

Today’s news below.

Microsoft and Meta earnings get different reactions



Call it a tale of two Ms. 

Meta and Microsoft both reported earnings on Wednesday, talking up their AI businesses and vowing to pump ever more astounding sums into the data centers and infrastructure that powers the technology. 

Investors loved Meta, which grew revenue an impressive 24% year-over-year, to $59.89 billion in the last three months of the year. The credit, the company said, goes to AI, which is helping Meta target users with content and ads more effectively than ever before. Meta forecast its AI-focused capital expenditures could rise to as much as $135 billion this year, nearly double the $72 billion it reported in 2025. Shares of Meta jumped 7.5% in response.

No such luck for Microsoft, which posted $81.3 billion in revenue, up 17% year-over-year and ahead of analyst expectations. Like Meta, Microsoft is investing aggressively in AI infrastructure: cap-ex was $37.5 billion in its fiscal second quarter, up from $34.9 billion in the preceding quarter. Investors were pickier with Microsoft though, finding fault with its Azure cloud business growing at a slightly slower pace than in previous quarters (despite the fact that it still grew a healthy 39%). Microsoft shares fell more than 5% in after-hours trading.—AO

Tesla swaps 'sustainable energy' for 'amazing abundance'

Tesla's Q4 earnings report was full of surprises, none of which had much to do with its actual results (revenue of $24.9 billion was down 3% year-on-year, but ahead of Wall Street targets).

The real news, as Fortune's Jessica Mathews reports, was the basket of surprises that CEO Elon Musk unveiled. Among them, a $2 billion Tesla investment in one of his own companies (the artificial intelligence firm xAI), the elimination of the Model S and the Model X vehicles from its lineup to make room in the factory for building Optimus robots, and a new mission statement that replaces "sustainable energy" with "amazing abundance."

The moves underscore the profound transformation underway at the car maker as it loses ground in the EV market to Chinese rivals. “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy,” Musk said. —AO
