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, Stephen Schwarzman's estimated net worth is about $31.1B(31.1 billion US dollars). That places Stephen Schwarzman at #14 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
Stephen Schwarzman co-founded Blackstone in 1985 and has led it into the largest alternative asset manager in the world. His estimate values the Blackstone Holdings partnership units he reports as owned, which exchange one-for-one for listed common stock, at Blackstone's share price.
How the fortune was built
Schwarzman and Peter Peterson started Blackstone as a merger advisory boutique, raised their first buyout fund in 1987, and expanded into real estate, credit, and hedge-fund solutions before the 2007 listing. He has kept most of his founder economics in partnership units rather than selling.
What drives the estimate
The estimate tracks Blackstone's share price. The unit count changes rarely because he does not sell; distributions and carried interest are not accumulated into the estimate.
Why the estimate changed
Stephen Schwarzman's estimate declined mainly because Blackstone Inc. shares decreased from the prior comparable close.

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.
Estimate history
Stephen Schwarzman: published estimate history
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.
The same history as an accessible table (50 points)
Uses the Census Bureau and HUD median sales price of houses sold in the second quarter of 2026, as published on FRED. The figure is revised and excludes closing costs and financing.
The count of 228,238,527 units comes from his August 28, 2023 Form 4, the most recent filing to state it; 3,686,266 units held in trusts for family members are excluded. He has filed no later Form 4 for Blackstone, so no reportable change has occurred, but the evidence date is shown as 2023. Cash distributions, art, and real estate are not modeled.
