Anthropic expects to spend at least $518 billion on AI infrastructure over a decade, according to a confidential prospectus cited by Reuters on September 29. The arrangements cover six partners and include cloud services, equipment leases and computing capacity. The company said about 80% of the amount is non-cancelable or must be paid regardless of actual usage. This gives infrastructure suppliers greater visibility into demand tied to the company, but does not guarantee them revenue or profits. The figure in the prospectus is a spending forecast over several years, not an amount Anthropic has already paid or a new announcement issued on October 27.

Commitments to Google total at least $111.1 billion between April 2026 and July 2033, while commitments to Amazon amount to about $110 billion between May 2026 and April 2036. The company also plans to spend $31.4 billion on Microsoft services between November 2026 and May 2033. The Microsoft arrangements include an exception allowing cancellation if the company materially fails to perform and does not remedy the failure. These dates show commitments extending across years, with terms that vary by supplier. Contract values therefore do not necessarily represent equal or guaranteed cash flows in every period.

The figure includes about $161.2 billion in equipment lease commitments tied to Broadcom, which the report described as largely non-cancelable. Anthropic also expects the value of computing capacity to be provided by AMD to exceed $20 billion. AMD has pledged to buy up to $5 billion of the company’s shares. Separately, Anthropic’s agreement with xAI could involve spending $84.5 billion on Nvidia-based computing capacity through 2029. Most of that agreement can be canceled with 90 days’ notice, showing that some capacity arrangements offer more flexibility than long-term service and leasing contracts.

Anthropic said in its prospectus that future demand for advanced systems could exceed available supply, and that computing availability may be the main constraint. In this context, it said it is gradually moving from relying solely on the cloud toward building its own infrastructure and dedicated data centers and renting chips directly. The shift reflects the range of commitments listed in the prospectus, from purchasing services to securing equipment and operating capacity. But it alone does not establish that the investments will generate returns commensurate with their cost. An investor told Reuters that “enthusiasm remains high” for AI’s potential, but investors “have become more selective” in assessing whether spending will justify high valuations.

In a separate disclosure, Anthropic reported a net loss of $80.7 billion in the first half of 2026. The company attributed $72.4 billion of the loss to a one-time accounting adjustment related to financing agreements. This places the scale of projected infrastructure spending alongside financial figures reflecting the impact of those agreements in its accounts. The reported loss does not mean that the full $518 billion in commitments was recorded as an expense or paid in cash. Contract details and terms remain important to understanding the difference between future commitments and realized spending.

The rise in AI stocks on October 26 was linked to Anthropic filing its IPO papers the previous day, according to Reuters, amid investor concern about debt-funded infrastructure spending. The Philadelphia Semiconductor Index rose more than 3% in the session, and Nvidia shares gained about 3%. Microsoft and Amazon shares also rose about 1% each. Shares of cloud computing companies CoreWeave and Nebius rose 5.7% and 2.3%, respectively, after the filing, recouping earlier losses. The move is not attributed solely to the commitments report published in September; coverage linked the session’s gains to the IPO filing.

The IPO filing puts the company on track for a potential stock market debut next month, according to an Associated Press report, while the final offering size, company valuation and share price remained undecided. It comes during a busy week for investors, with the Federal Reserve’s policy statement scheduled for Wednesday and growth and inflation readings due Thursday. More than a third of S&P 500 companies were also preparing to report results, including Alphabet, Microsoft and Amazon. These milestones bring together investor assessments of AI spending, monetary policy, economic data and corporate earnings. Anthropic’s market debut remains targeted for next month, with offering terms still undecided.
