Anthropic's 407 page IPO prospectus has two positives Wall Street is zeroing in on

Many people on Wall Street admit that they have not yet read all 407 pages of the IPO prospectus that Anthropic (ANTH.PVT) filed on Monday. An IPO prospectus is a document that explains a company's finances and plans before it sells shares to the public.

But investors are starting to agree on two things they like in the document: Anthropic gets money from a wider range of customers, and its revenue is growing faster than the cost of running its computing systems.

The prospectus shows that Anthropic's sales came from a wider range of customers this year. Customers outside its five biggest customers now account for about 79% of sales, up from 64% in the first quarter. In simple terms, this suggests that more customers are using Anthropic's technology.

Anthropic spent $8.9 billion on computing power and infrastructure in the first half of this year. That is more than it spent during all of 2025. However, these costs fell to 55% of sales, down from 201% of sales in the first half of 2025.

"Because revenue is growing faster than computing costs, and the company has used a relatively small amount of cash so far this year, we believe investors will likely see these as early signs that Anthropic could become profitable," said KeyBanc analyst Justin Patterson.

The prospectus shows that Anthropic's revenue in the first half of 2026 jumped to $16.3 billion, up from $1.1 billion a year earlier. The filing also reports a net loss of $80.7 billion in the first half of the year, pointing to heavy AI spending in the years ahead.

Investment bankers are reportedly aiming to value Anthropic at an enormous $1.5 trillion to $2 trillion when it goes public.

Anthropic could start trading on the public stock market before the end of November.

"I was in the boardroom when we kept having to approve spending on Amazon AWS, with almost no profit in the short term. There was a lot of spending," said Bing Gordon, co-founder of Electronic Arts and a former Amazon board member, on Sozzi Unleashed. "And there was one year when we said, 'Oh my God, it's $75 billion in spending on equipment and infrastructure.' That would be like the world's 10th-largest country ... The board was worried early on because we weren't generating more cash than we were spending. We were investing in the future. And Anthropic's story is similar. Invest in the future. The market is usually not very good at predicting the returns three or four years from now. So the bet is that this spending will pay off over those three or four years, just as it did with AWS."
