Anthropic reportedly struggles to secure cloud capacity ahead of IPO

Anthropic is reportedly struggling to secure cloud capacity from AWS, Google, and Microsoft, which increasingly see it as a competitor, according to a leaked S-1 filing cited by The Wall Street Journal. The filing indicates the company could spend more than $750 billion on cloud contracts, including deals still under negotiation, while also leasing its own data centers and working with third-party operators. Anthropic is concerned those operators may be less reliable because of their limited operating history.

According to the leaked filing, the company posted an $80.7 billion net loss and $16.3 billion in revenue in the first half of the year, with two customers accounting for about one-fifth of sales. Anthropic told prospective investors that third-quarter revenue had reached $16.8 billion, up 45% from the previous quarter. The filing also warns that the company could face liability for damages caused by harmful AI behavior that exceeds its insurance coverage. Anthropic is reportedly targeting a November IPO.

Why it matters · editorial interpretation

The case may indicate that Anthropic’s expansion is constrained not only by costs but also by access to cloud providers that view it as a competitor. For potential investors, customer concentration and the warning about liabilities for damages beyond insurance coverage add material risks to a possible IPO, according to the leaked filing cited by The Wall Street Journal.
