Correction (10 Oct 2026): this page previously showed undated or unsourced net-worth figures. We replaced them with one dated, named estimate and the holdings disclosed in filings, and we now tag every input as filing, reported or estimate.
How we source: figures on this page come from the company’s own filings (SEC 10-K, 10-Q, prospectus and earnings releases, or its annual report), with the period stated next to each number; outside estimates appear only labelled, with their source and date. Last refreshed October 2026. Our methodology.
An estimate is only as good as its date: it moves with share prices.

The Business Engineer view
What Parker’s fortune really measures
None of his stakes are in a filing, so every figure is an outside estimate. When the share count is not public, two of the three inputs are guesses, so treat any single figure with caution.
Read any net-worth figure with three questions: who estimated it, on what date, and at what share price. For the company behind the fortune, see Facebook and Spotify on FourWeekMBA.
