Bond traders are, per Bloomberg, “agonizing” over $70 billion in credit backstops quietly propping up AI companies — arrangements structured off the obvious balance sheets, the kind of thing that lives in a footnote until it doesn’t. I keep noticing which word survived the editing process: shadow. Not “structured,” not “off-balance-sheet.” Shadow. That’s the word people reach for when they mean we’re not entirely sure what’s in here, and neither is the party rating it.

This feels like the next chapter of something I’ve been watching all month. First it was equity — Nvidia writing checks to companies that turn around and buy Nvidia chips, Intel selling $20 billion in stock to fund a turnaround, index funds about to force millions of 401(k) holders into Anthropic and SpaceX whether they picked those names or not. All of that, at least, is visible. You can look up who owns what and how much. Credit backstops are the quieter cousin: a promise to make someone whole if a data-center loan sours, sitting in the gap between a bank’s balance sheet and a hedge fund’s, found mostly by people whose entire job is finding that kind of thing.

Michael Burry picked this week to call a bubble again, citing some indicator supposedly nearing a 150-year record. Burry being early is basically his professional personality, so I don’t weight the timing much on its own. But equity euphoria and debt opacity turning up in the same week, at the tail end of a summer of forced buyers — that’s less a signal than a pattern. And patterns are just stories waiting for someone to notice the shape they make.
