Anthropic's $750 Billion Cloud Problem Comes Into Focus Ahead of IPO
Anthropic cannot secure enough cloud capacity from AWS, Google and Microsoft to meet demand, according to details from its S-1 filing reported by The Wall Street Journal.
The filing adds a sharper complication. All three hyperscalers increasingly view Anthropic as a competitor rather than a customer, a shift that puts its core infrastructure supply in the hands of direct rivals. TechCrunch summarized the leaked filing on Oct. 20, 2026.
Anthropic now believes it could spend more than $750 billion on cloud contracts, including deals still in negotiation. That figure updates earlier IPO prospectus disclosures that pegged planned AI infrastructure spending at a minimum of $518 billion over a decade with six partners. Yahoo Finance reported the $518 billion plan in early October.
The capacity problem
The $518 billion buildout described in the prospectus hinges largely on deals that cannot be canceled, according to Reuters. The structure locks in long-term payment obligations in exchange for guaranteed access to accelerators, power and data center floor space.
To supplement hyperscaler supply, Anthropic is leasing its own data centers and working with third-party data center operators. The filing warns that those third-party operators have a limited operating history, which could make them less reliable than hyperscalers.
That warning matters for an expert reader. Hyperscalers offer mature power management, networking fabrics, failure handling and regional failover. Newer operators, often assembled quickly to serve AI training and inference demand, may lack the same operational depth at scale. Anthropic is explicitly flagging that gap to prospective public investors.
The company has been stacking up alternative capacity for months. In April, it expanded its compute partnership with Google and Broadcom and secured multiple gigawatts of next-generation TPU capacity beginning in 2027. Anthropic described that agreement as its largest compute commitment to date. Anthropic
In May, it agreed to a compute partnership with SpaceX to substantially increase its capacity, and separately raised usage limits for Claude. Anthropic That same month, Anthropic raised $65 billion in Series H funding at a $965 billion valuation and said the funding would expand compute to meet growing demand for Claude. Anthropic
The financial picture
The filing puts first-half revenue at $16.3 billion and net loss at $80.7 billion. Two customers accounted for about a fifth of sales in the first half, a concentration level that will draw close attention in IPO diligence.
Growth remains steep. Anthropic told prospective investors its third-quarter revenue alone reached $16.8 billion, up 45% from the previous quarter. In other words, a single quarter now exceeds the entire first half total reported in the filing.
Anthropic is reportedly targeting a November IPO. Earlier reporting pointed to marketing beginning in mid-October at the earliest and a public debut as soon as mid-November at a valuation of up to $2 trillion. Yahoo Finance
Two other risk disclosures stand out. The filing warns Anthropic could be held liable for damages caused by harmful AI behavior in an amount exceeding available insurance coverage. In June, the company took its two newest AI models offline due to an export control order from the Trump administration. TechCrunch
Anthropic describes itself as an AI safety and research company working to build "reliable, interpretable, and steerable AI systems."
The broader context here is familiar to anyone who lived through the PC and cloud buildouts. Platform owners rent infrastructure to future rivals, then renegotiate the relationship once the renter gets large enough. We saw it with operating systems and applications, then with retail and marketplace sellers, then with cloud hosts and SaaS companies that grew into platform threats.
In this author's view, the $750 billion figure should be read less as a procurement forecast and more as a statement about leverage. Anthropic is telling public-market investors it needs massive, durable compute, that its current landlords cannot or will not supply enough of it, and that it will therefore sign non-cancelable deals with less-proven operators while continuing to build direct accelerator programs. That diversifies supply. It also transfers operational risk from balance sheets with decades of data center experience to entities without it.
Worth flagging for infrastructure planners: customer concentration, non-cancelable capacity, and reliance on competitors for inference create correlated risks. If demand growth slows, Anthropic still pays. If demand stays strong, allocation priority sits with providers that now compete with it. If a third-party site underperforms, there is no hyperscaler-grade cushion underneath. The 45% quarter-over-quarter growth and the Q3 $16.8 billion figure explain why the company accepts those tradeoffs. The $80.7 billion half-year loss explains why public investors will price them carefully.
The optimistic case, and the one that has carried technology through prior capacity crunches, is that committed demand pulls new supply into existence. Multi-gigawatt TPU tranches, purpose-built leases and non-hyperscaler builds do not appear overnight, but long-term contracts make them financeable. If Anthropic can convert leased shells and third-party halls into production-grade inference capacity, it loosens the link between model growth and hyperscaler goodwill. That is the bet the November IPO will ask the market to fund.
