Anthropic's IPO filing reveals a cloud compute squeeze by its own partners

The News

Anthropic is finding it harder to buy the computing power it needs from the very cloud giants that once courted it, according to an S-1 filing leaked to The Wall Street Journal and covered by TechCrunch on 20 October 2026. The filing reportedly says Amazon Web Services, Google and Microsoft increasingly treat the Claude developer as a rival rather than simply a large customer.

The scale of the appetite is striking. Reuters and the Financial Times reported in late September that Anthropic believes it could spend more than $750 billion on cloud contracts, with some of those deals still under negotiation. To diversify, the company is leasing its own data centres and signing up third-party operators, though the filing flags that those operators have a "limited operating history" and may prove less dependable than the hyperscalers.

The numbers behind the IPO story are equally large. Per the Journal, Anthropic posted an $80.7 billion net loss in the first half of the year on $16.3 billion in revenue, with two customers making up roughly a fifth of sales. Reuters separately reported that the company told prospective investors last week that third-quarter revenue alone reached $16.8 billion. The listing is reportedly targeted for November. Anthropic did not immediately respond to TechCrunch's request for comment.

Why It Matters

The filing exposes an awkward truth about frontier AI: the companies that rent out the chips are also building competing models. Netflix lived with a similar tension for years, running on AWS while Amazon built Prime Video. The difference now is cost: a single GPU squeeze can delay a model launch by months.

Customer concentration is the second red flag investors will weigh. When two clients account for about a fifth of revenue, the loss or renegotiation of one contract moves the whole business. When Uber filed its S-1 in April 2019, loss disclosures rather than growth dominated the debate; Anthropic's revenue jump will be read the same way, against the cost of compute.

Indian Angle

For Indian companies building on Claude, compute scarcity at the model maker is not an abstract problem. Most Indian enterprises access Anthropic's models through AWS Bedrock or Google Cloud's Vertex AI, both of which run regions in India. If hyperscalers prioritise their own models, Indian developers could face tighter rate limits or slower local rollouts, and any price rise hits rupee budgets.

The leaked filing's caution about third-party data-centre operators is also relevant to India's own infrastructure push. The IndiaAI Mission, approved in March 2024 with an outlay of Rs 10,372 crore, has relied heavily on private operators to supply subsidised GPU capacity, and has backed Sarvam AI to build a sovereign foundation model. Anthropic's experience suggests that control over compute, not just model talent, is what decides who can scale, which strengthens the case for domestic capacity that does not depend on a competitor's goodwill.

For Indian retail investors, a US listing of this size will be tempting. Resident individuals can invest abroad under the RBI's Liberalised Remittance Scheme, capped at $250,000 per financial year. The loss figures and customer concentration deserve more attention than the brand name.

FAQ

When is Anthropic expected to list?

According to The Wall Street Journal, Anthropic is targeting an initial public offering in November 2026. The company has not publicly confirmed a date, so the November window should be treated as a reported target until a final prospectus is filed.

Why are cloud providers reluctant to supply Anthropic?

The leaked S-1 reportedly says AWS, Google and Microsoft increasingly see Anthropic as a competitor. Each builds or backs its own models, so GPUs allocated to Anthropic are GPUs not used for their own products. That conflict is pushing Anthropic towards leased data centres and third-party operators.

Can Indian investors buy Anthropic shares after the IPO?

Yes, indirectly. Resident Indians can open accounts with brokers offering US stocks and remit money under the Liberalised Remittance Scheme, which allows up to $250,000 per financial year. Gains are taxable in India, and rupee-dollar movements affect returns.

Does this affect Indian businesses using Claude today?

Not immediately. Access through Anthropic's platform, AWS Bedrock and Google Vertex AI continues. The risk is medium term: constrained compute could delay new models in Indian regions or tighten limits and prices, so firms relying on one provider may want a fallback.
