Person profile
Co-founder and chief executive of Palantir Technologies
"Valued as of" is the effective date of the market closes, exchange rates, and filings inside the estimate. "Sources checked" is when the pipeline last verified those sources successfully. A weekend check can confirm a Friday valuation without inventing weekend movement.
As of September 4, 2026, Alex Karp's estimated net worth is about $10.2B(10.2 billion US dollars). That places Alex Karp at #21 among the people Net Worth Leader currently tracks.
This is an estimate of assets minus documented liabilities. It is not a cash balance, and many holdings may be restricted, pledged, illiquid, or difficult to value.
Alex Karp co-founded Palantir in 2003 and has been its only chief executive, taking the data-analytics company public by direct listing in 2020. His estimate values the Class A and Class B shares he reports in Form 4 filings, which he updates frequently because restricted stock units vest and are sold under prearranged plans.
Karp, a philosophy PhD with no engineering background, built Palantir around government and defense analytics before expanding into commercial software. Founder control rests on a special voting structure that does not affect the economic share count used here.
The estimate moves with Palantir's share price. Vesting awards add Class B shares while scheduled sales remove Class A shares, so the count drifts slowly.
Alex Karp's estimate declined mainly because Palantir Technologies Inc. shares decreased from the prior comparable close.
A one-day estimate change is not the same as income, profit, or a realized gain or loss.

Liabilities without a documented value are never shown as zero; they are simply not included, and that limitation is part of source coverage below.
100.0% of this profile's modeled gross value is supported by Tier 1 or Tier 2 evidence (primary filings, official documents, licensed market data, or audited accounts). The profile carries a strong coverage label.
No meaningful range beyond the central estimate is supported for this profile, so only the central value is published. Unknown liabilities are not evidence that no liabilities exist. No personal liability is documented for this profile, so none is deducted.
The timeline runs from June 12, 2026 to September 4, 2026; the latest estimate is higher than the first point. Points before August 20, 2026 are labeled modeled reconstructions: today's reviewed ownership records applied to the closing prices of each earlier market date. Published history begins August 20, 2026 and grows one point per completed market date.
