The mad scramble by Silicon Valley to build data centers for artificial intelligence is spilling over into debt markets with a slew of public and private mega deals since September. So-called hyperscalers would have to spend 94% of operating cash flow to pay for their AI buildout themselves and are turning to debt investors to help defray some of that cost, according to research from Bank of America.

Deals so far this year have raised almost as much money as all debt financings done between 2020 and 2024, the BofA research said.

Borrowing since September includes:

-- An $18 billion public corporate bond sale from Oracle

-- A $27 billion private bond for Meta's Hyperion data center

-- A $30 billion public corporate bond sale by Meta

-- A $38 billion private loan sale for Oracle/OpenAI data centers.
