Anthropic IPO gives employees $216 B in equity and reserves $160 B for future hires

Anthropic’s amended S-1, filed with the SEC, reveals that employees own roughly $216 billion in net equity at the top of the $78 price range, while a $160 billion pool is earmarked for future grants Jason Lemkin, SaaStr. The filing lists 1.77 billion employee options (average strike $2.91) and 1.07 billion unvested RSUs, together representing the $216 billion figure.

With about 5,300 employees as of 30 September 2026, the equity translates to roughly $41 million per person, though distribution is uneven; early hires hold the bulk of option value, while later hires mainly hold RSUs averaging $20 million each.

The IPO will sell $64.4 billion of stock, with founders collectively selling $1.85 billion. The secondary portion is 3 % of the deal, leaving 97 % as primary capital for the company.

Anthropic’s filing notes a revenue run rate of $81 billion as of 31 October 2026 and cites intense competition for talent in the Bay Area. The $160 billion reserve, representing 2.05 billion shares at $78, is intended to match or exceed offers from other B2B-AI startups, potentially redefining hiring and retention dynamics across the sector.
