Anthropic Offers Blackstone 10%+ Yield on Record $60B Chip Financing

TREE NEWS reports: Anthropic is offering Blackstone a yield of more than 10% to participate in a record-breaking $60 billion debt financing package, code-named “Project North Star,” aimed at funding the purchase of custom AI chips. Blackstone’s funds will subscribe to $9 billion of an $18 billion subordinated loan tranche, earning a 10% coupon plus additional returns from issuance discounts and fees. The deal, which will fund approximately 1.5 gigawatts of Google-developed Tensor Processing Units (TPUs), is expected to be the largest chip financing in history and serves as a critical test of investor appetite for AI-related debt.

Financing Structure and Cost Escalation

The debt is split into two tiers: roughly $42 billion in senior debt guaranteed by Broadcom, which co-develops the chips, and $18 billion in subordinated loans. Blackstone is taking half of the subordinated tranche, with the remainder to be sold to a broader group of investors in the coming months, potentially at lower rates. The financing is expected to be drawn by 2027 and then circulated in the institutional 144A bond market.

The 10% coupon represents a premium of over 300 basis points compared to the roughly 7% yield typically paid by borrowers with similar credit profiles in the public high-yield market. When discounts and fees are included, the effective yield gap is even wider. This premium reflects growing investor caution toward the concentrated financing demands of AI companies and the extra compensation required to anchor large, complex deals.

Just four months ago, Anthropic completed a $4.4 billion financing—code-named “Project Big Sky”—at an 8.5% interest rate. The rapid rise in borrowing costs underscores mounting wariness about the sector’s insatiable capital needs.

Market Implications

The deal has significant implications across asset classes:

• Credit Markets: The 10% yield on Anthropic’s subordinated debt signals that AI-related issuance is facing rising risk premiums. If more AI firms flood the bond market with large deals, high-yield spreads could widen further, particularly for technology issuers. The successful placement of the remaining $9 billion will be closely watched as a barometer of demand.
• Equities: Higher financing costs for AI infrastructure could pressure valuations of chipmakers and AI-focused companies. However, Broadcom’s role as guarantor of the senior tranche reinforces its strategic position in the AI supply chain. Investors will weigh whether rising capital costs slow the pace of AI capex or are absorbed by strong revenue growth.
• Crypto and Commodities: There is an indirect link: AI data centers compete for energy resources, and rising power demand could support natural gas and uranium prices. Crypto miners that have pivoted to AI hosting may also see competitive dynamics shift as financing costs rise.
• Currencies: The dollar-denominated nature of the deal reinforces demand for USD funding in the technology sector, though the macro impact is limited.

Strategic Context: A Time Arbitrage

Despite the high cost, Anthropic is pressing ahead with a clear strategic rationale. Blackstone has reportedly told its investors that this is a rare opportunity to invest in Anthropic-linked debt at high-yield levels before the company completes an IPO, which is expected to bring an investment-grade rating and significantly lower borrowing costs. In essence, Anthropic is paying up for compute capacity now while betting that a post-IPO rating upgrade will allow it to refinance at cheaper rates, smoothing its long-term capital costs. For early investors like Blackstone, the deal locks in above-market yields during a period of elevated risk.

Key Takeaways for Investors

• AI debt is repricing: The jump from 8.5% to over 10% in four months shows investors are demanding greater compensation for AI-related credit risk. Monitor high-yield tech spreads for contagion.
• Watch the remaining $9 billion: How the rest of the subordinated tranche is sold will indicate whether demand for AI debt is holding up or cracking.
• Broadcom’s guarantee matters: The senior tranche’s backing by Broadcom reduces risk for that layer, but the subordinated debt remains exposed to Anthropic’s execution and eventual IPO.
• IPO timing is critical: Anthropic’s path to investment-grade status hinges on a successful public listing. Any delay could strain its ability to refinance at lower costs.
• Energy and infrastructure plays: The 1.5 GW TPU buildout highlights the physical footprint of AI—power and cooling suppliers may benefit regardless of financing terms.
