Count the company once
A company's equity value contributes to one claim in an index version. Multiple people may share credit inside that claim.
Methodology · company-claim-v1
One company. One claim. Every assumption visible.
The index measures current company equity held beyond the credited builders. It does not measure moral worth, consumer surplus, taxes, wages, or lifetime investment returns.
The core calculation
Wealth for others=Total company equity−Builder equity retained
Six operating rules
Designed to resist easy inflation.
Subtract company equity
Only the credited builders' holdings in the claimed companies are subtracted—not unrelated assets or total personal net worth.
Group real eras
Founder and later operator eras can share a claim when the current company clearly spans both. The attribution rationale must be explicit.
Aggregate distinct companies
One builder may aggregate multiple companies, but those companies are then unavailable to any overlapping claim.
Expose uncertainty
Confidence reflects ownership-source quality, share-class complexity, private valuations, and unresolved attribution questions.
Version every snapshot
Market prices move continuously. Published values remain tied to a timestamp and methodology version so changes can be reconstructed.
What this is
A narrow ownership measure.
It asks how much current equity attached to a company-building claim is owned by somebody else.
It does not prove that one person created that value alone. Employees, cofounders, investors, suppliers, public infrastructure, market power, and luck all matter.
Confidence rubric
What the labels mean.
Specific recent ownership filings and a directly reconcilable equity-value basis.
Credible ownership evidence with share-class, award, depositary-share, or timing complexity.
A useful directional estimate that still requires a full holdings or attribution audit.
