Anthropic IPO Reveals the $518B Cost of Frontier AI

Revenue grew 11x as compute commitments reached at least US$518B
On September 28, 2026, Reuters revealed new details from Anthropic's confidential IPO filing, showing 2025 revenue rose to about US$4.6 billion while compute and infrastructure costs reached US$7.33 billion. Anthropic has committed at least US$518 billion to cloud, compute and other AI infrastructure over roughly a decade.
Anthropic confidentially submitted its draft Form S-1 to the U.S. Securities and Exchange Commission on June 1. The filing isn't public yet, so the financial details come from journalists who reviewed the prospectus rather than an SEC document investors can inspect themselves. Anthropic also hasn't set the number of shares, IPO price or offering size yet.
The filing gives public market investors something private AI companies rarely provide. Anthropic's revenue is growing at extraordinary speed, but so are the costs and commitments needed to keep Claude running and improving. The question isn't simply whether demand for AI keeps rising. It is whether that demand can grow fast enough to absorb infrastructure contracted years before the customers arrive.
Anthropic Revenue Rose 11x As Compute Costs Tripled
Anthropic generated about US$400 million of revenue in 2024 and nearly US$4.6 billion in 2025, an increase of roughly 11.5 times in one year. Compute and infrastructure spending moved just as aggressively, rising to US$7.33 billion in 2025, about three times the prior year level. That one expense represented roughly 58% of Anthropic's US$12.65 billion of operating expenses and about 1.6 times annual revenue.
| 2025 metric | Amount | What it tells investors |
|---|---|---|
| Revenue | ~US$4.6B | About 11.5 times 2024 revenue |
| Compute and infrastructure | US$7.33B | About 159% of revenue and 58% of operating expenses |
| Operating loss | US$8.06B | Operating costs still exceeded the rapidly growing revenue base |
| Net loss | ~US$42B | Includes a large financing related accounting charge |
| Cash and short term investments | US$20.28B | Year end liquidity before later financing |
| Future infrastructure commitments | At least US$518B | Multi year cloud, compute and infrastructure contracts |
The US$42 billion net loss needs a bit of context. Roughly US$34 billion came from an accounting charge tied to financing instruments that can convert into Anthropic shares. That doesn't mean Anthropic spent US$42 billion in cash operating Claude. The operating number is US$8.06 billion loss generated after revenue and operating costs are compared.
Does that mean the economics are getting worse as Anthropic grows? The current 2026 numbers make that difficult to conclude. Preliminary second quarter revenue exceeded US$11.5 billion, up from US$4.73 billion in the first quarter, and Anthropic reported positive adjusted operating income for the quarter. Those aren't audited full year results, but they show how quickly the picture is changing.
Rapid revenue growth doesn't remove the infrastructure problem, and it makes securing enough compute more urgent.
Anthropic Has Committed At Least US$518B To Compute
Anthropic expects to spend at least US$518 billion over roughly a decade across six infrastructure partners. Reuters reports that about 80% of those commitments are noncancelable or require payment regardless of how much capacity Anthropic actually uses. The known agreements include at least US$111.1 billion with Google, US$110 billion with Amazon, US$31.4 billion with Microsoft and about US$161.2 billion of Broadcom related equipment lease obligations.
Is US$518 billion debt?
No. The figure combines different cloud, compute, equipment and infrastructure contracts spread across years. Some arrangements can also be cancelled. Anthropic's agreements with xAI, for example, could involve up to US$84.5 billion of Nvidia based capacity through 2029 but are largely cancelable with 90 days notice.
The less flexible contracts create the bigger financial issue. Anthropic is reserving enormous amounts of future capacity before it knows exactly how quickly model efficiency, compute prices, customer demand and competition will change. Its filing reportedly warns that access to compute could constrain growth before customer demand does. If Anthropic is right, securing capacity early protects revenue growth. If demand, pricing or technology changes faster than expected, fixed infrastructure commitments become much harder to absorb.
BGC's compute infrastructure markets are creating price discovery and risk management around compute and memory capacity. When capacity is scarce, expensive and contracted years ahead, compute becomes something Anthropic has to finance and manage like major infrastructure, not just pay for as a cloud service.
The supplier relationships are unusual too. Amazon and Google are major Anthropic investors as well as infrastructure providers, and their platforms help distribute Claude. Microsoft also supplies infrastructure while competing across AI. These relationships give Anthropic capital, compute and distribution, but they also make a small group of large technology companies important to several parts of the business at once.
Demand is also concentrated. Nearly one quarter of 2025 revenue came from two customers, while many larger customers are not locked into long term contracts. Anthropic therefore has substantial fixed commitments on the infrastructure side while parts of its customer base remain comparatively flexible. That mismatch deserves your attention.
A US$2T Anthropic IPO Would Price Growth Years Ahead
Reports that Anthropic may seek a valuation above US$2 trillion doesn't make the company worth US$2 trillion today. The firms last reported private valuation was about US$965 billion in May, so US$2 trillion remains a target until shares are actually priced.
Anthropic could also reach public markets before its closest frontier AI rival. OpenAI CEO Sam Altman said in September that OpenAI's public market timeline now extends beyond 2026, pushing any listing to at least 2027. Anthropic could therefore become the first major frontier model company to give public investors a direct look at the economics of building and operating AI at this scale.

Preliminary second quarter 2026 revenue exceeded US$11.5 billion, while Anthropic's annualized revenue run rate reportedly passed US$65 billion by the end of July. Investors will have to decide how much of that acceleration can persist and how much compute, capital and fixed infrastructure Anthropic must secure to support it.
Reuters reports that roughly 80 of the prospectus's 261 main pages cover risks, including the possibility that more capable AI could resist shutdown, conceal information, facilitate cyber or biological misuse and cause catastrophic harm.
Talking Point
Revenue can multiply in a year while infrastructure contracts extend for a decade. The market now has to decide whether that growth can remain fast and profitable enough to justify committing hundreds of billions of dollars to compute before future demand is known.
