Key Notes
- Anthropic is reportedly offering Blackstone funds a yield above 10% on junior debt backed by five years of chip lease payments.
- The proposed $9 billion investment would form part of an $18 billion junior tranche within a broader $60 billion financing.
- The reported terms highlight funding costs and repayment risk as the Claude developer expands computing capacity ahead of a possible IPO.
Anthropic is offering Blackstone Inc. (NYSE: BX) a yield above 10% to help finance a proposed $60 billion AI-chip transaction, according to the Financial Times, putting a steep price on part of the Claude developer’s computing expansion.
Blackstone-managed funds would invest $9 billion in junior debt backed by five years of Anthropic’s lease payments for specialized Google chips, the FT reported, citing people familiar with the matter. That investment would cover half of an $18 billion subordinated tranche, rather than the entire financing.
The reported coupon is 10%, with discounts and fees lifting the yield above that level. The proposed terms are not a completed placement or a guaranteed investment return. Reuters’ separate dispatch said it could not immediately verify the FT report.
A Higher Price for Junior Chip Debt
The FT compared the offer with roughly 7% yields for similarly rated borrowers in public bond markets. It also reported that a similar $4.4 billion Anthropic financing four months earlier carried an 8.5% rate. Those comparisons point to a higher price for this proposed junior funding, although instruments with different seniority, liquidity and contractual protections are not interchangeable.
Junior debt sits behind senior claims in the repayment hierarchy. The SEC’s bond guidance explains that priority depends on the terms of the security, and subordinated creditors generally have lower-ranking claims than senior creditors.
That helps explain why a large headline yield cannot be assessed in isolation. Investors need to know which cash flows support repayment, what protection exists if payments stop and where their claims sit relative to other lenders. A contractual promise to make lease payments provides a source of repayment; it does not remove the risk that those payments are disrupted.
The coupon and yield also measure different things. A fixed coupon sets scheduled interest relative to principal, while the price paid for the debt affects the investor’s yield. Issue discounts and fees can therefore push the effective return above the stated coupon, assuming payments arrive as agreed.
The Buildout Already Has a Financing Framework
The latest reporting follows a publicly announced partnership between Broadcom Inc. (NASDAQ: AVGO), Apollo Global Management Inc. (NYSE: APO) and Blackstone’s credit and insurance business.
The companies’ June 9 announcement introduced the AI XPV Platform with an initial $35 billion transaction led by Apollo alongside Blackstone. That transaction was intended to support more than one gigawatt of Anthropic computing infrastructure, with deployment at Fluidstack-based sites expected to begin in mid-2026.
The broader platform targeted more than 20 gigawatts of capacity for frontier AI developers through 2028. Those figures describe announced financing and deployment plans, not proof that every planned facility is already operating.
The June announcement establishes the existing business relationship. It does not independently confirm the pricing, final allocation or closing of the newer $60 billion package described by the FT.
Google Chips Underpin Anthropic’s Expansion
Google, part of Alphabet Inc. (NASDAQ: GOOGL), develops tensor processing units, or TPUs, for AI workloads. Anthropic’s April 6 compute agreement with Google and Broadcom covered multiple gigawatts of next-generation TPU capacity expected to start coming online in 2027.
Anthropic said most of that capacity would be in the United States. It also described a diversified hardware strategy using Google TPUs, Trainium processors from Amazon.com Inc. (NASDAQ: AMZN) and GPUs from Nvidia Corp. (NASDAQ: NVDA), allowing it to allocate workloads across different systems.
Blackstone’s involvement in Google’s computing ecosystem extends beyond chip-lease debt. Google announced a separate TPU-cloud joint venture in May, backed by an initial $5 billion Blackstone equity commitment and targeting 500 megawatts in 2027.
As we reported, that venture expands access to Google’s AI infrastructure. Its equity commitment is distinct from the $9 billion junior-debt investment now being reported.
Revenue Growth Faces a Funding Test
Anthropic’s expanding business provides the commercial backdrop. As we previously reported, the company told investors that third-quarter revenue reached $16.8 billion, roughly 45% above the previous quarter, while reporting positive adjusted earnings and cash flow ahead of a possible IPO.
Rapid sales growth nevertheless leaves a separate financing question: whether future cash generation can support long-term infrastructure commitments on the terms investors require. Adjusted profitability does not by itself establish the cash available after all investment and financing obligations.
That concern reaches beyond Anthropic. Intel Corp. (NASDAQ: INTC) and Broadcom executives recently warned that capital availability could constrain AI expansion, as we reported. The proposed Blackstone terms give that debate a concrete focus: the cost and repayment priority of the funding, alongside the amount being raised.
