Why two dates?
"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, Mark Zuckerberg's estimated net worth is about $210.5B(210.5 billion US dollars). That places Mark Zuckerberg at #6 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.
Summary
Mark Zuckerberg founded Facebook in 2004 and controls Meta Platforms through high-vote Class B shares held in entities he reports as beneficially owned. The estimate values those shares at the Class A market price because each converts one-for-one, so it tracks Meta's share price closely.
How the fortune was built
Zuckerberg launched the service from a college dormitory, kept voting control through the 2012 initial public offering with a dual-class structure, and has sold shares gradually through the Chan Zuckerberg Initiative under prearranged plans while retaining the large majority of his original stake.
What drives the estimate
Meta's Class A share price drives the estimate. Scheduled sales through CZI Holdings trim the count in small increments that appear in Form 4 filings within two business days.
Why the estimate changed
Mark Zuckerberg's estimate rose mainly because Meta Platforms, Inc. shares increased 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.
Source coverage and uncertainty
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.
Documented assumptions applied to this profile
Trust and holding-company shares reported as beneficially owned are counted. Shares held through revocable trusts, grantor retained annuity trusts, family partnerships, and holding companies are counted when the person reports them as beneficially owned with sole voting and dispositive power. Shares held by independent charitable foundations or explicitly disclaimed by the person are excluded.
