Estimate

Current Assessment

Ferdowsi co-founded Dropbox and held a large founder stake before the company's 2018 IPO. Dropbox's S-1 listed 51.4 million Class B shares held through Ferdowsi trusts and 6.6 million Class A restricted stock awards. At a recent Dropbox share price near $27.47, that full historical position would be worth about $1.6 billion before taxes. The estimate is discounted because current public sources do not show how many shares he still owns or how much he has sold since the IPO.

Key caveats

The strongest evidence is historical, not a verified current ownership table.
The full share-value calculation is gross and does not account for taxes, sales, or vesting conditions.
No reliable public evidence was found for personal real estate, private investments, or liabilities.

Evidence gaps

Current Dropbox shareholding directly attributable to Ferdowsi.
Post-IPO stock sale history after he stopped appearing as a current company insider.
Non-Dropbox assets and liabilities.

Confidence

Low confidence

55/100

Important source, ownership, or liability gaps materially limit the estimate reliability.

Key Evidence Gaps

Verified current Dropbox shareholding directly attributable to Arash Ferdowsi.
Ferdowsi-specific Form 4, Form 144, Schedule 13D/G, proxy, or other ownership history after the IPO.
Evidence of actual post-IPO sale proceeds and tax treatment.
Direct current exchange or Nasdaq closing price for the exact valuation date.
Direct reputable wealth reporting from Forbes, Bloomberg, or a comparable source.

Public Caveats

This is a modeled estimate, not a verified real-time billionaire ranking.
The strongest evidence is Dropbox's 2018 S-1, which supports historical founder ownership but not current holdings.
Current public sources reviewed did not verify how many Dropbox shares Ferdowsi still owns or how much he has sold since the IPO.
The full-retention Dropbox share value is gross before taxes, sales timing, vesting conditions, and diversification outcomes.

Uncertainty Drivers

No current public beneficial ownership figure for Ferdowsi was located.
Post-IPO sales, 10b5-1 plans, private transfers, and tax payments are not fully observable after he left current listed Dropbox roles.
The 6.6 million Class A RSA component was subject to service and stock-price vesting conditions, and current personal allocation was not verified.
No reliable public record of private investments, real estate, philanthropy, or liabilities was found in this run.
Market price is from a secondary quote page rather than a direct Nasdaq feed.
