Anthropic’s Founders Pledged to Donate Most of Their Stock. Their IPO Tells Another Story.
The AI giant Anthropic disclosed its initial public offering filing with the SEC on Monday in what is expected to become one of the largest stock debuts in history. The offering is set to take place around the middle of November. While the public documents do not disclose the exact valuation of the startup or […]
Anthropic, the leading AI company, filed its IPO paperwork with the SEC, paving the way for what could be one of the biggest stock debuts in history. Exact figures for the company's valuation and share details remain undisclosed, with estimates suggesting a valuation ranging between $1.5 and $2 trillion. This valuation mirrors Elon Musk's SpaceX IPO, which reached $2.1 trillion last summer.
However, despite the impressive valuation, Anthropic's IPO does not match the founders' previous pledge to donate 80% of their equity to philanthropic causes. The latest SEC filing suggests that these philanthropic commitments are "voluntary and revocable," subject to various factors including tax and estate planning, market conditions, and the co-founders' personal circumstances.
Additionally, while Anthropic raised $16.3 billion in revenue in the first half of 2026, it reported a net loss of over $80 billion. The company is also burdened by $6.2 billion in debt, primarily owed to Amazon. Moreover, it owes $475 billion to various compute power providers, including Google ($115 billion), Amazon ($110 billion over ten years), and SpaceX ($120.5 billion for Nvidia GPUs through 2029).
The IPO filing indirectly addresses the co-founders' philanthropic pledge, stating that it is "uncertain" and will depend on numerous factors such as market conditions and the founders' individual situations. The filing also highlights the political and regulatory challenges Anthropic may face, including potential moratoriums on new data center construction and an evolving global regulatory landscape.
Furthermore, the company discusses the significant risks associated with AI development, noting that a catastrophic AI-related incident could have disastrous consequences for humanity. Given the potential for catastrophic harm, Anthropic states that finding adequate insurance coverage will be extremely challenging, as no single insurer or the insurance industry in aggregate may have the capacity or expertise to underwrite such extensive exposure.
