Anthropic pays 10% interest: Wall Street's fear premium on the AI boom
Anthropic is reportedly offering a 10% yield to secure billions in chip debt, revealing exactly how risky Wall Street thinks the AI boom is.

What happened
Anthropic is reportedly offering Blackstone a yield above 10 percent to anchor a massive chip financing deal. The Financial Times reports this is part of a 60 billion dollar debt package arranged by Broadcom. Blackstone would put up 9 billion dollars of its own capital for a junior slice of the debt. The remaining half of that 18 billion dollar junior tranche would be syndicated.
The money is earmarked for a massive compute scale up. It underwrites Anthropic's five year lease for Google tensor processing units. The total commitment on that lease is a staggering 125.2 billion dollars. That buys 3.5 gigawatts of Google TPU capacity expected to come online starting in 2027. A 42 billion dollar senior secured tranche led by banks covers about a third of that lease.
The deal structure is complex and internally dubbed Project North Star. Anthropic's own prospectus flags potential conflicts of interest since Broadcom is acting as both the chip supplier and the lender. The prospectus warns that triggering certain defaults could accelerate lease obligations and cut off access to the credit line. The debt instruments also include an option to convert into Anthropic shares. This structure extends a massive AI partnership that Broadcom, Apollo, and Blackstone struck in June.
Key facts
- 10% — Coupon rate offered to Blackstone
- $60 billion — Total Broadcom-arranged debt package
- $125.2 billion — Total commitment on the five-year Google TPU lease
- 3.5 gigawatts — Google-TPU capacity expected by 2027
- 7% — Typical rate for similar public credits
Why it matters
The pricing is the real story here. Similar borrowers in public bond markets pay around 7 percent. Offering a 10 percent coupon plus potential equity conversion shows that private capital is demanding a massive risk premium for lease backed AI debt. Wall Street is funding the AI boom. But they are pricing in the very real possibility that these massive compute investments do not generate returns on schedule. The syndication of the remaining junior debt will test if the broader market accepts this risk.
This sets a new baseline for AI infrastructure costs. If a top tier lab like Anthropic has to pay double digit yields to finance its compute, the cost of capital for everyone else just went up. The market demands a high price for single name exposure to Anthropic. This debt burden will inevitably trickle down. The developers and enterprises paying for API access will ultimately foot the bill for these massive interest payments.
For builders
API costs will stay high
Anthropic has to service massive debt on a 125 billion dollar compute lease. They cannot afford a race to the bottom on model pricing. Builders should expect premium models to maintain premium API costs.
Compute is a financial instrument
Broadcom is acting as both vendor and lender. The hardware supply chain is now deeply entangled with private credit. Startups negotiating large compute contracts are dealing with Wall Street debt structures.
My take
Wall Street loves the AI hype. But their money tells a different story. Charging a 10 percent yield to one of the most important AI labs in the world is a blunt admission of fear. They are betting on the future while making absolutely sure they get paid first if the bubble pops.
