Indirect exposure
Calculate your indirect Anthropic exposure
A $1,000 investment in Amazon or Alphabet carries an estimated indirect Anthropic exposure that this calculator computes from reported stakes and current market caps, with every assumption shown.
How does indirect exposure work?
You cannot buy Anthropic shares, but you can own a listed company that holds them, and your share of that stake is your indirect exposure. It is the holder's Anthropic stake, valued at the last priced round, divided by the holder's own market capitalisation, multiplied by what you have invested. Nothing about it is a claim on Anthropic itself: it is a fraction of a fraction of a private position that the market may already price differently.

What are the assumptions?
Three inputs drive the result: the holder's reported stake, Anthropic's last priced post-money valuation, and the holder's market capitalisation as of the date you supply it.

- Market capitalisation is the figure you type in, as of the moment you read it. We do not store it and we do not date it for you.
- Dilution: every round after the last priced one reduces the stake, and the stake percentages in circulation are reported, not filed.
- Liquidation preferences and share class terms are not public, so the stake is valued as if it were common equity. It may not be.
- Tax inside the holding company, and any holding-company discount, are ignored.
Why is the exposure so small?
Because the stake is small relative to the holder: a 14 percent stake in a $965 billion company is about $135 billion, and set against a multi-trillion-dollar market capitalisation that is a few percent of what you own.
The arithmetic is the same in every case: the stake's implied value divided by the holder's market capitalisation is a low single-digit percentage, so most of what you buy is the holder's own business, not Anthropic. Enter a market capitalisation above to see the exact percentage.
