This price range suggests the company aims to raise between $57 billion and $64 billion from the public offering itself. However, the total capital raise could reach approximately $90 billion. This figure includes an agreement with strategic investors—including Broadcom, Google, and Nvidia—to purchase an additional $26 billion in shares at the IPO price. If successful, this would eclipse the $75 billion initially raised by Elon Musk’s SpaceX in June, which ultimately sold over $85 billion worth of shares.
The scale of the raise is designed to support an implied valuation of up to $1 trillion. This marks a rapid ascent for the company, which was valued at $965 billion following a $65 billion funding round in May. Reports had previously indicated that Anthropic’s valuation had already soared to $1.2 trillion on the secondary market due to surging demand for its shares. The company, founded in 2021 by CEO Dario Amodei and former OpenAI members, is targeting a launch date for mid-November, though the exact date will be announced “as soon as practicable.”
The filing provides a stark financial picture of the company’s trajectory, highlighting both explosive revenue growth and the immense costs associated with training and operating frontier AI models. In its original S-1 filing, Anthropic reported a total net loss of approximately $42 billion in 2025 against revenue of $4.6 billion. However, an amended filing submitted earlier this month revealed a significant shift in the third quarter of 2025, where the company generated nearly $17 billion in revenue.
Despite this revenue surge, the company remains in the red, reporting a $567 million operating loss in the same quarter. The primary driver of these costs is infrastructure. Anthropic has disclosed $895 billion in committed spending on compute and infrastructure, with nearly half of that expenditure expected to occur by the end of 2030. This heavy capital requirement is central to the company’s strategy, as it seeks to secure the massive computing power necessary to train and serve its models.
The financial structure of the IPO is complicated by what industry observers term “circular financing.” Major cloud providers, including Amazon, Google, and Microsoft, are not only selling the compute resources Anthropic needs but are also significant investors in the company. According to the filing, Anthropic has committed to purchasing over $600 billion in infrastructure services from these partners over the next decade. Specifically, the company plans to buy at least $110 billion in cloud computing services from Amazon, $114.5 billion from Google, and $44.9 billion from Microsoft. This interdependence raises questions about market dynamics and the concentration of power in the AI infrastructure sector.
Despite the public nature of the offering, Anthropic intends to retain control in the hands of its founders. The company is structured as a Public Benefit Corporation (PBC), a legal form that allows it to prioritize social and environmental goals alongside shareholder profits. In this structure, the seven founding partners hold a single “Class F” share that represents 50.1% of the total voting power. This arrangement ensures that the founders retain full authority over critical corporate decisions, even as the company lists on the public stock market.
The IPO sets a new benchmark for the valuation of AI companies, reflecting both the high demand for generative AI technology and the unprecedented capital requirements of the sector. For investors, the offering presents a high-risk, high-reward opportunity tied to the future of artificial intelligence. For the broader technology industry, the sheer scale of the raise underscores the intensifying competition among AI labs, which are now competing not just on model performance, but on financial endurance and infrastructure scale.
The next major milestone for Anthropic will be the confirmation of its specific trading date, which is expected to be announced in the coming weeks. The market will be watching closely to see if the company can sustain its revenue growth pace and how the public markets will react to the massive infrastructure commitments that define its business model.
