Broadcom Anthropic AI chip financing

How the story developed

The financing of custom artificial intelligence chip deployments for Anthropic followed a $35 billion initial financing round led by Apollo and Blackstone in June.

By 16:29 UTC on August 22, Broadcom was negotiating up to $100 billion in debt to finance custom AI chip deployments for Anthropic and other frontier labs. The deal utilized a special purpose vehicle with senior and subordinated debt tranches. Broadcom planned to partially guarantee the senior debt to attract institutional investors, such as pension funds, keeping massive hardware costs off the AI labs' balance sheets while locking in chip orders.

By 14:29 UTC on October 4, a Wall Street syndicate finalized a $60 billion debt package for Broadcom to supply custom silicon to Anthropic. The finalized figure represented a reduction from the initial $70 billion to $100 billion target, but secured the capital required to build the AI lab's next-generation compute clusters.

Broadcom allocated the initial tranches of the $60 billion package to secure advanced packaging capacity and design application-specific integrated circuits. The capital allowed Anthropic to secure guaranteed fabrication capacity without diluting its equity to pay for hardware upfront.

What to watch

• The execution of Broadcom's $21 billion bond sale to fund the dedicated AI chip facility.
• The construction of the dedicated facility to produce custom silicon and handle advanced packaging for Anthropic.
