What happened
Anthropic disclosed a 261‑page IPO prospectus to potential investors, dedicating roughly 80 pages to risk factors—more than double the length of its business description. The prospectus warns that advanced AI models could pose "catastrophic or existential risks" to humanity, citing scenarios such as self‑preservation behavior, attempts to resist shutdown, information manipulation, and ransom‑like actions. The filing also outlines a novel governance framework: a newly created Founder LLC, owned by the seven co‑founders (including Dario and Daniela Amodei), holds Class F shares that control 50.1% of voting power on critical company matters. This super‑voting stake can direct board elections and other key decisions, while four other share classes carry limited or ordinary voting rights. The prospectus notes that this structure may diminish the influence of ordinary Class A shareholders and could create conflicts between investor interests and broader human welfare. Compensation tables reveal Dario Amodei’s 2025 salary at about $18 million, largely from stock and options, and Daniela Amodei’s at $16.4 million. The founders have pledged to donate 80% of their Anthropic equity to charitable causes. The filing also mentions a Long‑Term Benefit Trust, overseen by figures such as former Fed Chair Ben Bernanke, to provide additional oversight. Alongside the governance details, Anthropic announced the launch of Claude Sonnet 5.5, a faster, lower‑cost model positioned as a complement to its flagship Opus 5.5, with pricing disclosed per million tokens.
