Published net-worth figures are estimates assembled from ownership assumptions, company valuations, debt, market inputs, and reporting. They are snapshots—not audited personal balance sheets.

Real-time estimate as of August 29, 2026
Forbes says fortunes substantially tied to private companies are updated daily and adjusted using industry- or region-specific market indexes when available. Its annual methodology also considers private-company stakes, known debt, and charitable giving.
Bloomberg’s subject analysis used an almost-25% ownership assumption, valued Cox Communications and Cox Automotive with enterprise-value-to-EBITDA multiples from identified public peers, and allocated a share of corporate-level debt as a liability.
The two figures above were published four months apart. They may use different operating results, comparable-company multiples, debt assumptions, liquidity discounts, transaction information, and update schedules. The August 20, 2026 completion of the Charter–Cox Communications transaction also postdates Bloomberg’s displayed April snapshot.
Even when two publishers begin with a similar ownership percentage, small changes in the assumed value of a large private enterprise can produce large differences in an owner’s estimated wealth.
02 / How to read the figures
Use the date and source every time
Say “Forbes estimated,” not “is worth.”
Keep the as-of date attached to the number.
Do not equate an ownership interest with spendable cash.
Expect the estimate to change as publishers update their models.
Do not infer a current personal stake from transaction consideration paid to a company subsidiary.
