A lot of comments praising this summary, but I'll criticize it: it's still too verbose, and misses the point.
Meta wants to fund this project, but doesn't want the debt on own its books (because it would impact its vanity AA credit rating). Debt investors are happy to finance a special purpose vehicle guaranteed (in a non debt way) by Meta at a credit rating almost as good as Meta's (say, A). No one is confused this is Meta getting financing for their own project; they've just put it in a wrapper for vanity credit score reasons.
Levine wrote about it and his writing is better than ChatGPT, this snarky website, and obviously mine: https://www.bloomberg.com/opinion/newsletters/2025-10-29/put... .
Still too verbose. Here's a TL;DR.
Meta is borrowing a whole lot of money and they're lying about it to investors.
So… ‘vanity’ ratings… what’s the point of them then.
