Bank of America, Blackstone, Citi and Morgan Stanley announced a $63 billion transaction on October 26 to pay for Broadcom AI chips that Anthropic will lease. The joint press release, posted on Broadcom's newsroom, says deliveries are expected to start in calendar 2027.

How the structure works

A newly formed special purpose vehicle (SPV) will use committed financing from the four firms to buy Broadcom XPU AI accelerators and networking products. The SPV then leases them to Anthropic, per the release. Anthropic does not buy the hardware outright under this structure.

The financing has two layers:

  • First lien: Bank of America, Citi and Morgan Stanley are arranging this portion.
  • Second lien: Blackstone is the sole provider of the committed portion.

Broadcom is providing "residual value support" to the SPV for an amount equivalent to the first-lien portion. The release does not define that term, so how the support works in practice is not public.

The deal is part of the compute capacity agreement Broadcom announced earlier, the release says.

What the release does not say

The release gives no split between first and second lien, so the size of Broadcom's support is unknown. It does not say who owns the SPV's equity, the lease length or rent, the interest rate, or how much hardware the money buys.

It also contains no statement from Anthropic. Its quotes come from Blackstone, Morgan Stanley, Citi, Bank of America and Broadcom CEO Hock Tan. Tan says the transaction "validates that there is capital available to finance such growth."

Bloomberg also reported the deal. Its article is paywalled, so we relied on the release for every detail here.

Why it matters

Anthropic filed its IPO paperwork the same day. Our S-1 breakdown notes that the filing leaves the dollar total of its compute commitments blank, so this announcement gives a fuller picture of how some of that capacity gets paid for. It is not a substitute for the numbers Anthropic has yet to publish.

Debt-funded AI hardware is becoming a pattern. Our story on SpaceX's GPU lease financing with Apollo describes a similar lease structure for a different buyer.

What this means for you

Nothing changes for Claude users today. The release announces no pricing or product change, and it does not say how the chips will be used.

The practical signal is about supply. Money for Broadcom-built chips is now lined up, but deliveries do not begin until 2027. If you follow Anthropic's stock or the AI chip trade, watch for the loan sizes and lease terms in later filings. This is not investment advice.
