Every potluck has the moment where you survey the table and realize all forty guests brought potato salad. Nobody planned it. Everyone just heard potato salad was popular. Carlyle, one of the biggest names in private credit, just published a white paper pointing at the table and politely asking whether anyone brought anything else.

The paper, out October 1, warns that private credit firms rushing to finance the AI buildout risk the same concentration problems that have plagued lenders exposed to software companies. The industry may need to supply roughly $1 trillion for AI computing infrastructure, more than half of all the private credit assets currently under management, in a buildout expected to top $5 trillion through 2030. Carlyle says failing to put clear limits on concentration could be "the biggest mistake of all," though its Mark Jenkins stresses the firm wants to take the risk, just in a balanced way.

Here's the jargon, served on a paper plate. Concentration risk means a few borrowers, mostly giant tech companies, account for most of the loans, so everyone's fortunes ride on the same few bets. If one dish turns, the whole table goes home sick. Carlyle's paper adds that data center credit is more speculative than software lending and more tied to the broader economy, and that many of the financing structures are still largely untested, which is a polite way of saying nobody has seen what happens to this casserole after a bad quarter. Our own contribution, not Carlyle's: new chip generations keep arriving, and old ones do not age like wine.

The irony is almost too neat. The last trade everyone crowded into was software, which made up about half of private equity deals between 2020 and 2022. Then generative AI showed up and introduced obsolescence risk for software lenders, and now many of the same lenders are crowding into financing AI. The thing that disrupted the last potluck is catering the next one.

Back in August, we covered Nvidia lining up six financial giants and more than $500 billion to treat graphics cards like real estate. Carlyle's paper is, in effect, the home inspection that arrived after everybody put in an offer.

Carlyle isn't telling anyone to leave the party. It's just suggesting the next round of dishes include something besides potato salad.
