Anthropic Secures BB+ Rating Amid AI Debt Concerns
Anthropic has received a BB+ credit rating from Kroll Bond Rating Agency (KBRA), placing the artificial intelligence developer one notch below investment grade as it seeks access to billions of dollars in financing for its expanding computing infrastructure.
The assessment was issued in June 2026 but has only now become public, offering fresh insight into how lenders are evaluating one of the world’s fastest-growing AI businesses. BB+ is the highest speculative-grade rating, commonly described as junk status, and indicates that Anthropic could potentially secure cheaper borrowing if its financial position strengthens sufficiently to qualify for investment-grade credit.
The rating preceded a $35 billion financing arrangement led by Apollo Global Management to support the acquisition and deployment of advanced computing chips through Broadcom’s AI infrastructure platform. The transaction illustrates how private credit and structured financing are becoming increasingly important as AI developers seek computing capacity without funding every investment directly from their own balance sheets.
Approximately $4.4 billion of junior debt within the financing package was directly exposed to Anthropic’s creditworthiness and received a BB+ rating with a stable outlook. The remaining financing benefited from Broadcom’s guarantee, creating a distinction between the risks assumed by different groups of lenders.
The junior debt was issued at a yield of approximately 8.5%, compared with an interest rate of 5.75% on the senior financing. The 2.75-percentage-point difference demonstrates the financial importance of credit protection and repayment priority, although the two debt tranches also carry different contractual terms.
Anthropic reportedly had no debt on its own balance sheet in late June, relying instead on financing arrangements involving business partners and special-purpose vehicles. Nevertheless, its future financial performance remains important because infrastructure financing ultimately depends on the company’s ability to generate sufficient revenue to support its computing commitments.
KBRA’s assessment was based on limited financial disclosures, including revenue figures, adjusted operating income and internal forecasts. The agency was not provided with certain important measures, including free cash flow and earnings before interest, tax, depreciation and amortisation, requiring analysts to develop estimates and use a credit risk scoring approach rather than a complete conventional financial model.
The limitations are significant because strong revenue growth does not necessarily translate into cash available to meet long-term obligations. Anthropic reported a third-quarter annualised revenue run rate of approximately $16.8 billion, representing growth of nearly 50% from the preceding quarter, and told investors it had achieved adjusted operating profitability for two consecutive quarters. The company expects to spend more than $500 billion on computing resources and infrastructure over the next decade. Further financing options reportedly under consideration include convertible notes worth up to $42 billion and a separate package of approximately $60 billion to fund additional custom AI processors developed through relationships involving Google and Broadcom.
For investors, an eventual investment-grade rating could broaden Anthropic’s access to pension funds, insurance companies and other institutions whose investment mandates restrict speculative-grade debt. Lower borrowing costs would become increasingly valuable as the company expands its computing requirements and considers a potential stock market listing. However, the wider market is becoming more cautious about debt-funded AI expansion, with investors questioning whether future revenues will justify the scale of infrastructure spending. The rapid pace of technological development also creates uncertainty about how long expensive processors will retain their commercial value.
Anthropic’s BB+ rating is therefore an important credit benchmark rather than a guarantee of investment-grade status. Its ability to obtain affordable long-term financing will depend on sustained commercial growth, stronger financial disclosure and convincing lenders that its infrastructure commitments can generate reliable cash returns.
