Analysis
The IPO has no price range and no share count, but the control math is already fixed. Anthropic, PBC filed its registration statement on Form S-1 for a Nasdaq listing under the symbol ANT, with Goldman Sachs and Morgan Stanley named as prospectus contacts, according to the company. The number of Class A shares and the price range had not been determined at filing, and the statement was not yet effective.
What is determined is who runs the place afterward. Before the offering, Anthropic will issue a single Class F share to an LLC owned by its seven co-founders, Fortune reported. One share, 50.1% of the vote on nearly all shareholder matters, zero economic rights, in Fortune’s reading of the S-1. Class A shares—the ones sold to the public—get one vote each, but all Class A shares together are capped at 49.9% of the vote. Class N shares, held mainly by strategic partners including Amazon and Google, share the economics but cannot vote except where law requires. A single Class T share held by the Long-Term Benefit Trust elects a majority of the board and has no expiration date.
The filing itself warns that the structure "may effectively eliminate" Class A holders' ability to influence major decisions, including a sale of the company, according to Fortune. The co-founders' control lasts until fewer than three of the seven remain in the LLC for 90 days—a sunset clause measured in careers, not quarters.

Why it matters
Class A buyers get a stake in the business, but the filing itself warns the structure may effectively eliminate their say over major decisions, including a sale.
