Anthropic S Corporate Structure
Short summary
A breakdown of Anthropic's pre-IPO governance, focusing on board composition and the Long Term Benefit Trust that controls voting power independent of typical shareholder structures. The author argues Anthropic should publicly disclose the trust agreement and voting agreement since the company claims to serve humanity's long-term interests with AI development.
- The board has 7 seats: 2 for common shareholders (the Amodeis), 1 for preferred shareholders, and 4 controlled by the Long Term Benefit Trust—meaning the LTBT effectively controls the company despite owning just one special class T share
- The LTBT trustees elect themselves and operate under a non-public trust agreement; there's no public mechanism for shareholders to dissolve or override the trust without its consent
- Anthropic's certificate of incorporation gives the Electing Preferred Director veto power over certain stock issuances and likely grants additional powers through non-public investor agreements, but most governance details remain opaque
Full summary
Anthropic recently amended its incorporation documents ahead of a planned IPO, and the author breaks down how the company is actually structured. The board has seven seats: two held by founders Dario and Daniela Amodei (elected by common shareholders), one by Yasmin Razavi representing preferred shareholders, and four by the Long Term Benefit Trust—a mysterious entity that holds special class T shares. The CEO gets tiebreaker votes when the board splits. What makes this setup unusual is that the Electing Preferred Director can block certain stock issuances, but the real power appears to concentrate in the LTBT, which controls four board seats and can't be dismantled without its own consent.
The Long Term Benefit Trust is the structural linchpin here. It owns one class T share that gives it disproportionate control, and its governance happens entirely behind closed doors—the trust agreement isn't public, and there are no disclosure requirements. The trustees apparently elect themselves annually, though additional selection rules might exist in unpublished documents. The LTBT's stated purpose is to prevent Anthropic from transferring sufficiently capable AI models or having a majority of shares transferred without its approval. This gives it veto power over major decisions about the company's most valuable assets.
The author criticizes this opacity directly. Given that Anthropic is a public benefit corporation claiming to develop AI "for the long term benefit of humanity," there's a case that shareholders and the public deserve to know who actually controls it and under what terms. The trust agreement and voting agreement remain confidential, which makes it impossible to assess what constraints actually govern the LTBT's power or how transparent its decision-making really is. The author expects these documents might surface during the IPO process, but argues they should be published now.
