Broadcom Inc.

(NASDAQ:AVGO) traded down more than 5% Friday as a new estimate put an enormous number on the debt machine behind the chipmaker's AI expansion.

BofA analyst Tom Curcuruto estimates Broadcom's chip-financing vehicle could reach $370 billion of senior debt by mid-2029 at a 20-gigawatt scale, including roughly $150 billion of new issuance in 2027 alone, Reuters reported Friday.

That does not mean Broadcom itself would owe $370 billion.

The financing vehicle would raise the debt, but Broadcom has agreed to backstop some of the customer lease obligations.
