Behind every boom, at some point, are the people who have to pay for it. In AI right now, that’s the lenders — and they’re getting more cautious. A Bloomberg report this week shows how the mood is shifting.
What happened
At least four borrowers had to sweeten their loan terms this week to entice investors, according to Bloomberg — among them AI cloud provider CoreWeave and security firm Proofpoint. CoreWeave raised the yield on a $2.6 billion loan to 5.5 percentage points over the benchmark and offered the paper at a discount of 96 to 97 cents on the dollar.
What’s the money for? GPUs and compute capacity that CoreWeave provides under long-term take-or-pay contracts — for customers like Anthropic, Jane Street, Midjourney, Hudson River Trading and Anysphere.
The signal underneath
More interesting than any single number is the trend. The cost of insuring against a CoreWeave default over five years jumped more than 50% this month — to its highest level since December. In other words, the credit market is starting to price in the risk of a possible AI bubble. Not with panic, but with a sharper pencil.
My take
This is one of those moments where AI euphoria meets hard financial math. Models keep getting better, demand keeps growing, data centers keep going up — but someone finances those GPUs, and they want to be paid for the risk. For Anthropic this isn’t an acute danger: the capacity still arrives, it just gets a bit more expensive somewhere in the chain. The question I find fascinating is the one underneath: how long does a market carry investments whose payoff still lies in the future? I’m not a financial advisor, and this isn’t investment advice. But as an observer, I notice the part of the AI story that runs on debt is being told more soberly right now. That’s healthy.
