Forbes estimates Pierre Omidyar’s net worth at $13.7B (real-time, 10 Oct 2026, #228 in the world). Most of it is eBay and PayPal shares (size reported, not filed). It is an outside estimate that moves with the share price, not a disclosed figure.
Sources: Forbes (10 Oct 2026). Analysis by The Business Engineer.
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.
The most widely cited figure is Forbes’s: $13.7B on 10 Oct 2026, #228 in the world. It is an outside estimate, not a figure Omidyar or any company has disclosed.
Other outlets publish different figures, and each changes with share prices. Use one source consistently, and always note its date.

What drives the number

The Business Engineer view
What Omidyar’s fortune really measures
He is no longer an eBay director, so his holdings are not in current filings. 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 eBay on FourWeekMBA.
