• Anthropic already holds a BB+ speculative-grade rating from Kroll, with concerns mounting over its long-term creditworthiness despite a massive IPO filing.
  • The company's $63 billion Project North Star financing relies on Broadcom (AVGO)'s investment-grade support, but a junk issuer rating could raise borrowing costs and limit access to high-grade investors.
  • With over $131 billion in cash and short-term investments, near-term liquidity is strong, but hundreds of billions in computing commitments through 2045 raise questions about future cash generation.

A Rating Already in the Books

Anthropic's credit risk is not a future possibility—it's a present reality. The Financial Times reported on October 16 that Kroll Bond Rating Agency assigned the AI developer a rating one notch below investment grade in June, later identified as BB+, the highest speculative-grade category. The disclosure predates the company's October 26 IPO filing, which exposed the central tension: exceptional revenue growth and substantial liquidity alongside hundreds of billions of dollars in long-term computing commitments.

The distinction between liquidity and long-term creditworthiness is crucial. A large cash balance can support near-term operations without guaranteeing that future cash generation will cover decades of contractual obligations. Portfolio manager Tony Trzcinka of Impax (IPX.L) summarized Anthropic's position as "very strong liquidity and extraordinary future obligations."

The IPO and Financing Framework

Anthropic filed publicly on October 26, with a listing reportedly targeted for November. Reports suggest proceeds of approximately $100 billion and a valuation potentially reaching $2 trillion, though final terms have not been set. On the same day, Broadcom announced a $63 billion financing arrangement involving Bank of America (BAC), Citi (C), Morgan Stanley (MS), and Blackstone (BX). A special-purpose vehicle will purchase chips and networking equipment and lease them to Anthropic, with deliveries expected to start in 2027. Broadcom supplies residual-value support to senior lenders.

The cash figures require careful reading. AP reported $131.7 billion available at June 30; other filing-based coverage describes this as cash, cash equivalents, and short-term investments—broader than a narrower cash-only figure such as the headline's $112 billion. The numbers should not be treated as directly interchangeable.

Why the Rating Matters

A speculative-grade issuer rating could restrict access to the deeper pool of high-grade bond investors, including many insurance companies and pension funds. It could also increase financing costs or preserve collateral requirements, and prolong dependence on partners such as Broadcom to support infrastructure financing.

The distinction between issuer and transaction ratings is crucial. Broadcom-supported financing can receive investment-grade treatment even when Anthropic itself does not. The earlier $35 billion Big Sky transaction illustrates this; Broadcom supported most of that financing. A guarantee for senior lenders does not necessarily protect every participant equally, particularly subordinated lenders.

Financial Performance and Governance

Anthropic's scale is now substantial: approximately 250 customers each generated at least $10 million of revenue over the preceding year, while its top five customers represented about 25% of revenue this year. First-half 2026 revenue reached $16.3 billion, versus approximately $1.16 billion a year earlier—roughly fourteenfold growth. The net loss of $80.7 billion includes a $72.4 billion one-time financing-related accounting adjustment and should not be interpreted as equivalent cash burn.

The accounting distinction matters. PitchBook (MORN) analyst Harrison Rolfes argues that including computing costs used to train future models leaves roughly 45 cents of each revenue dollar, rather than the 85 cents implied by the reported gross margin. That is an analyst's economic adjustment, not the company's reported measure.

Governance is another factor. The seven founders will collectively retain 50.1% of shareholder voting power through a special Class F share. The Long-Term Benefit Trust separately retains a central role in selecting the board.

Industry and Economic Context

Anthropic's expansion illustrates an industry shift: leading AI developers increasingly require financing structures associated with large physical infrastructure, not just software businesses. Banks, private-credit managers, cloud providers, and chip suppliers now share the funding burden through leases, special-purpose vehicles, and contractual support.

That creates connected risks. Several companies are simultaneously Anthropic's suppliers, investors, or prospective lenders. Trzcinka says rating agencies must assess these "circular counterparty relationships," along with the company's short operating history and commitment schedule. Financial strength at one participant therefore does not eliminate exposure elsewhere in the chain.

The build-out supports demand for chips, networking equipment, data centers, and electricity. However, Anthropic's prospectus warns that inadequate power availability and growing opposition to data centers could constrain expansion. Competition also threatens the revenue assumptions underlying the spending, with customers potentially choosing cheaper or open-source models when incremental improvements in frontier models do not justify their cost.

Political and International Risks

The IPO filing describes government policy as a material business risk. Anthropic warns that its AI-safety positions and executive statements could lead to disproportionate scrutiny or enforcement. Reporting on the prospectus describes export restrictions imposed over the summer that temporarily interrupted access to certain models; reimposed controls could constrain international sales, model availability, and data-center expansion.

Relationships with Amazon (AMZN), Google (GOOG), Microsoft (MSFT), and Broadcom could attract antitrust attention—relevant because those same relationships support infrastructure access and financing. The filing also highlights competition from Chinese models and geopolitical exposure associated with advanced-chip manufacturing in Taiwan.

What to Watch

The decisive developments will be final IPO terms, any ratings from Moody's (MCO), S&P (SPGI), and Fitch, and financing conditions. Anthropic's revolving facility provides a concrete incentive to obtain investment-grade ratings: certain guarantees and security interests would be released if at least two of the three major agencies award that status.

A successful $100 billion equity raise would strengthen funding capacity, but it would not automatically resolve how agencies assess long-term commitments, demand uncertainty, or counterparty concentration. The favorable scenario is that enterprise adoption and operating efficiency grow quickly enough to support the capacity already contracted. The adverse scenario is that slower demand growth, cheaper competing models, or power constraints leave Anthropic paying for underused infrastructure. Its prospectus warns that many payments remain payable regardless of actual capacity use.

Expert assessments remain divided. Impax's Trzcinka sees today's balance sheet as potentially supporting investment grade, subject to the agencies' treatment of future obligations. Reuters Breakingviews (TRI) is more skeptical of the apparent profitability, arguing that maintaining margins could require tripling sales as growth slows. Neither view is an announced rating decision or a certain forecast.

Correction: An earlier version of this article misstated the timing of Anthropic's credit rating. The BB+ rating was assigned in June, not after the IPO filing.
