No verifiable current net worth. Forbes profile pages for him returned 404, and aggregator sites gave conflicting figures ($1.2 to $3.1 billion) with no checkable source. The only hard number is an SEC Form 4 holding of 746,209 Costco shares as of January 17, 2018, which InsiderTrades.com values at about $698 million at that date. Magnitude 4 rests on that stake and could be a band low if he held more or the price has risen enough.

A 2018 Form 4 holding of 746,209 shares is the only figure found; later sales or gifts were not checked.
