HOW THIS IS CALCULATED
We take the shares Alex Karp reports owning in their most recent SEC Form 4 and multiply by the latest share price. That gives a stake value you can check against the filing itself. Everything beyond that stake — real estate, private holdings, cash, past compensation — is estimated or simply not public, and we say so rather than roll it into one number.
BIOGRAPHY
Alex Karp was born in New York in 1967 and raised in Philadelphia by a pediatrician father and an artist mother, both social-justice activists. He collected degrees far from Silicon Valley: philosophy at Haverford, a law degree from Stanford, and a doctorate in social theory from Goethe University in Frankfurt, written in German.
He met Peter Thiel at Stanford Law, and in 2003 the two co-founded Palantir, the secretive data-analysis company that works with governments and large enterprises. Karp has been its chief executive since the start and took it public in 2020, becoming an unlikely tech-founder billionaire.
Karp is a co-founder, so his wealth is dominated by a founding stake in Palantir, which is the equity this page measures.

*Estimated net worth is a third-party figure from Forbes (2026), not our own calculation; it is an estimate that changes with the market.

Share counts are the latest reported on SEC filings and change as the executive trades; the price is the last close, so the stake value moves with the market.
