What did we learn from the filings about
the company's founders, so the Amodei siblings,
and how they control Anthropic at this point?
Anthropic has seven co-founders,
all of which are still there, including, as you mentioned,
Dario and Daniela Amodei.
They're going to collectively hold a single special share,
carrying about 50.1% of shareholder
voting power.
So that means that public shareholders,
although they get a vote, the filing actually says
that the structure may effectively eliminate
their ability to influence major decisions.
Anthropic is also a public benefit corporation
so directors are sort of instructed to balance
profits against developing AI for this broader good of humanity.
Each co-founder has also pledged
to donate 80% of their equity to philanthropy
and the company's put about 5% of shares into
its public benefit fund as well.
And you said that right now the price range on the valuation of
the company is blank. When can we expect to get a sense of that?
Obviously before the listing itself
but we're expecting that before Thanksgiving
so hopefully shouldn't have to wait for too
But there has been a bit of speculation recently.
Originally, Anthropic was reported
to be targeting this $2 trillion valuation.
There have been some reports recently they might
be scaling this back to $1.5 trillion.
Still a lot of money, but a significant markdown.
