Robert Armstrong and Hakyung Kim Published October 27 2026. Anthropic’s S-1 filing reveals lots of interesting things about the economics of its business, including $800bn in spending commitments. We’ll write about the money soon; for now we confine ourselves to the company’s elaborate governance structure, which is built around a delicate balance of powers, like the constitution of a country.
The two power centres are the company’s seven founders and the five trustees of its Long-Term Benefit Trust. The trustees’ job is to preserve the balance between the financial interests of shareholders and the company’s non-financial “purpose” (having AI be good for humanity, basically). The LTBT has the right to nominate four of the seven-member board of directors; the board in turn makes the big corporate decisions. Voting shareholders decide who gets the remaining three seats.
“Voting shareholders”, in effect, means the founders, who maintain 50.1 per cent voting control through a special class of stock. To a first approximation, then, the LTBT’s trustees pick a majority of the people with final say on what matters. But the first approximation is not where the action is. The action is in the nominating committee of the board. The nominating committee has three members and takes decisions by majority vote. Crucially, two of its members must be minority board directors — those chosen by the founders.
The author dislikes Anthropic’s structure but likes its counterbalanced approach better than Meta’s founder control. So, in sum: it could be worse.
