• Anthropic's upcoming IPO may not guarantee an investment-grade credit rating, according to a warning from Blackstone (BX) to investors reported by the Financial Times.
  • The AI developer filed for a Nasdaq (NDAQ) listing under the ticker ANT on October 26, but rating agencies have yet to publish formal assessments.
  • The caution underscores concerns over whether future earnings can support roughly $637 billion in computing commitments, even as the company holds about $132 billion in cash.

A Creditworthiness Question, Not a Demand Problem

The headline lands less than a week after Anthropic filed for an IPO under the proposed Nasdaq ticker ANT. The central question, as framed by the reported Blackstone warning, is not whether investors will buy the shares but whether Anthropic's future earnings can carry the weight of enormous computing obligations. People familiar with the matter said the private credit giant conveyed the caution to investors in recent days. Blackstone declined to comment. Anthropic did not respond to a request for comment by publication time.

The distinction matters. An investment-grade rating would open a deeper pool of institutional funding and potentially lower borrowing costs. Anthropic's $15 billion revolving credit facility provides for guarantees and collateral protections to be released if at least two major agencies award investment-grade ratings. As of this week, Moody's (MCO), S&P (SPGI) and Fitch had not yet published ratings on the company, so the Blackstone warning should not be read as a formal rating decision.

The Financing Backdrop

The caution follows a burst of financing activity. On October 26, Broadcom (AVGO) announced a $63 billion financing arrangement involving Bank of America (BAC), Citi (C), Morgan Stanley (MS) and Blackstone. A special-purpose vehicle will buy chips and networking equipment and lease them to Anthropic, with deliveries expected from 2027. Blackstone is providing the committed portion of the junior, second-lien financing. Earlier in October, reports said Anthropic offered Blackstone a yield exceeding 10% on $9 billion of debt backed by five-year chip-lease payments. That figure applies to a particular financing tranche, not to all Anthropic borrowing.

It is a structure that increasingly defines the AI buildout: banks, private-credit funds and public investors sharing the financing burden as development shifts from venture funding toward large-scale infrastructure borrowing. Major technology companies' combined AI infrastructure spending is on pace to exceed $730 billion this year, according to Reuters.

Growth Amid Heavy Commitments

Anthropic, founded in 2021 by former OpenAI researchers, sells the Claude family of models, chatbot and coding services to consumers and enterprises. Its latest private funding round valued it at $965 billion, and more than half of Fortune 500 companies are customers, according to recent reporting. First-half 2026 revenue reached approximately $16.3 billion, roughly 14 times the year-earlier level. The company posted a first-half net loss of $80.7 billion, including a $72.4 billion non-cash convertible-financing valuation charge—a figure not equivalent to cash burn. Its first-half operating loss was $693 million, but the second quarter alone delivered $974 million in operating profit. Liquidity stands at roughly $132 billion in cash, and first-half operating cash flow was positive at $3.9 billion.

Against that, future commitments loom large: approximately $637 billion in computing contracts spanning signed and expected deals—not all current debt or equally firm obligations. Separately, uncommenced leases totaled $321 billion at June 30. Those figures should not be added together without reconciling their scope.

The company's interconnected model adds a wrinkle for analysts. Major cloud providers are simultaneously investors, computing suppliers and distribution partners; Amazon (AMZN), Google (GOOGL) and Microsoft (MSFT) accounted for 48% of first-half revenue through their platforms. Around 80% of revenue depends on usage rather than flat subscriptions, making pricing and consumption central to cash-flow predictability. Impax (IPX.L) portfolio manager Tony Trzcinka said current leverage supports investment grade, but the agencies must weigh Anthropic's commitment schedule, short operating history and circular counterparty relationships.

Governance and the Road Ahead

Dario Amodei remains CEO and Daniela Amodei remains president and board chair. The IPO-related changes concern governance rather than a reported executive replacement: Reed Hastings is lead independent director, founders retain 50.1% voting power through a special share, and the Long-Term Benefit Trust can elect a board majority. Anthropic will remain a public benefit corporation.

Near term, the key developments are agency rating decisions, final IPO terms, updated revenue growth and the treatment of lease commitments. A useful precedent is SpaceX (SPCX), which obtained investment-grade ratings around its 2026 listing and subsequently issued $25 billion of investment-grade bonds—a possible route, not an assurance Anthropic will follow it. The earlier $35 billion "Big Sky" chip-financing transaction received investment-grade treatment largely with Broadcom support, a reminder that transaction-level and corporate ratings must remain distinct. For now, the headline points to financing uncertainty rather than a settled rejection by rating agencies or an imminent liquidity crisis.
