Anthropic’s founders’ 80% giving pledge could be worth nearly $80 billion

Anthropic's seven founders have pledged to donate 80% of their personal stakes in the AI company, potentially totaling nearly $80 billion. CEO Dario Amodei discussed the commitment in a January essay, highlighting the responsibility of wealth generated by the technology. The pledge was reaffirmed in the company's IPO filing, confirming that the founders "have each pledged to dedicate 80% of their personal equity in Anthropic to philanthropic causes."

The seven founders collectively own around 1.69 billion shares, which, based on the latest private funding-round price, could be worth approximately $99.3 billion. When 80% of this value is calculated, it amounts to about $79.4 billion, or roughly $11 billion per founder. Anthropic's revenue grew to $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier.

The company plans to list on the Nasdaq under the ticker "ANT," with a potential IPO value ranging from $1.5 trillion to $2 trillion. The money could be directed through various philanthropic vehicles, and while the founders would relinquish most of their personal stake, they would still retain 50.1% of voting power through a special share held by their Founder LLC.
