7 founders keep 50.1 percent of Anthropic

Anthropic's 7 co-founders will keep 50.1 percent of shareholder votes after the company lists its shares, its filing showed on the 26th of October 2026. The votes sit in 1 special share held by a company the 7 own together.

That share, called Class F, carries no claim on profits. The group is led by chief executive Dario Amodei and president Daniela Amodei.

Who is in the group

The other members are Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah, the filing says. Benjamin Mann, often called a co-founder, is left out of the group, Inc reported.

Who picks the board

A trust of 5 outside trustees picks most of Anthropic's board, Fortune reported. One seat is empty, and former Federal Reserve chair Ben Bernanke is one of the 4 members.

Public buyers get Class A shares. Together those can never hold more than 49.9 percent of the vote.

When it ends

The special share ends if fewer than 3 of the 7 founders stay in the group for 90 days, Fortune reported. A founder stays in by keeping 2 percent of their shares from the time of the listing.

Each co-founder has pledged to give away 80 percent of their Anthropic shares. Each owns about 240 million shares, Fortune reported.

Below we break down the vote

A founder could give away 98 percent of their shares and keep a seat, by our arithmetic. That would leave about 4.8 million shares each.

What is confirmed and what is not

The pledges are voluntary and can be withdrawn, the filing says. If most founders disagree on a vote, the share votes the way public shareholders split.

Key facts

7 co-founders hold 50.1 percent of votes through 1 share.
