Anthropic's Large Spending Commitments
Anthropic made its S-1 filing public on Monday. It reported revenue of $16.3 billion for the first half of the year, up from $1.16 billion in the first half of 2025. The company reported a net loss of $80.7 billion, mainly because of a $72.4 billion accounting charge related to convertible notes.
However, investors paid close attention to Anthropic's long-term spending commitments. These payments will also benefit companies that provide cloud services and AI computing equipment.
According to The Wall Street Journal, which cited the filing, Anthropic plans to spend $450 billion on cloud computing agreements over the next seven to ten years. It plans to spend $111 billion on Google cloud computing contracts, $110 billion with Amazon Web Services, and $31 billion with Microsoft, "regardless of actual usage."
The Journal also reported that Anthropic plans to spend up to $86 billion to rent Nvidia chips from smaller AI cloud providers Nscale and Lambda through 2033 and 2034, respectively. These deals would be in addition to its other cloud agreements.
Investors and Analysts React Positively to Anthropic's S-1
Analysts and investors generally responded positively to Anthropic's financial results. Some praised how quickly the company was growing and how widely its customers were spread across different businesses.
Anthropic's S-1 filing says the company will list its shares on the Nasdaq stock exchange under the ticker symbol "ANT." The Journal separately reported, citing people familiar with the matter, that the company plans to list its shares during the week of November 16.
