Anthropic is racing to secure cloud computing capacity for its AI models but finding major cloud providers increasingly see it as a rival, according to a leaked regulatory filing reported by The Wall Street Journal. The company, targeting a November initial public offering, reported $80.7 billion in net losses on $16.3 billion in revenue in the first half of the year, and warned it could spend over $750 billion on cloud contracts, some still being negotiated.

The leaked S-1 filing, reported by The Wall Street Journal, provides new detail on Anthropic's challenges. The company relies heavily on cloud services from Amazon Web Services, Google Cloud, and Microsoft, but those hyperscalers are becoming more reluctant to partner with a competitor. As a result, Anthropic is leasing its own data centers and working with third-party operators, though it worries about their reliability and limited operating history.

The filing also highlights Anthropic's financial position. The company brought in $16.3 billion in revenue in the first six months of the year but posted a net loss of $80.7 billion. Two customers accounted for about a fifth of sales, raising concentration risk. However, third-quarter revenue alone has already reached $16.8 billion, up 45% from the prior quarter, suggesting momentum. Anthropic is reportedly aiming for a November IPO and has been briefing potential investors on these metrics.

On the risk front, the S-1 warns that Anthropic could face liability for damages caused by harmful AI behavior that exceeds its insurance coverage, building on earlier disclosures about catastrophic risks.

Anthropic did not immediately respond to a request for comment.

Analysis

Why This Matters

Anthropic's ability to scale its AI models depends on cloud capacity; a shortfall could slow development and affect customers reliant on Claude.
The company's financial losses and customer concentration raise questions about its path to profitability as it pursues a public listing.
The liability warning underscores the unresolved question of who is responsible when AI systems cause harm, a central issue for the industry.

Background

Anthropic is a leading AI safety company founded by former OpenAI employees, known for its Claude family of language models. Like many AI firms, it relies on cloud computing from major providers to train and run its systems. The company has long emphasized safe development, including a focus on constitutional AI and responsible scaling. Its upcoming IPO is seen as a key test of investor appetite for pure-play AI companies with significant operating costs.

Key Perspectives

Anthropic: The company is pursuing aggressive expansion, with $16.8 billion in Q3 revenue and growing, but faces structural challenges in securing compute capacity from competitors while managing large losses and liability exposure. Cloud providers (AWS, Google, Microsoft): As the market for AI cloud services grows, they must balance being suppliers to AI startups while developing their own models and platforms that compete with companies like Anthropic. Investors: The IPO candidate offers high growth but with substantial risk, including single-customer concentration and unresolved liability frameworks that could lead to unpredictable costs. Critics/Skeptics: The $750 billion cloud spending projection and $80.7 billion loss raise questions about the business model's sustainability. Liability concerns may deter some investors, and reliance on a few large customers poses a risk if those relationships sour.

What to Watch

Whether Anthropic meets its November IPO timeline and the valuation it commands.
Progress on securing cloud capacity through its own data centers or new partnerships with non-hyperscaler operators.
Any developments in legal or regulatory frameworks for AI liability, which could directly impact Anthropic's risk profile.
