Person profile
Co-founder and chief executive of Coinbase
"Valued as of" is the effective date of the market closes, exchange rates, and filings inside the estimate. "Sources checked" is when the pipeline last verified those sources successfully. A weekend check can confirm a Friday valuation without inventing weekend movement.
As of September 4, 2026, Brian Armstrong's estimated net worth is about $4.6B(4.6 billion US dollars). That places Brian Armstrong at #29 among the people Net Worth Leader currently tracks.
This is an estimate of assets minus documented liabilities. It is not a cash balance, and many holdings may be restricted, pledged, illiquid, or difficult to value.
Brian Armstrong co-founded Coinbase in 2012 and leads the largest US cryptocurrency exchange, which listed by direct listing in 2021. His estimate counts the Class B shares held by his living trust and an in-the-money option grant, both valued at the Class A share price; personal cryptocurrency holdings are not included because no filing documents them.
Armstrong, a former Airbnb engineer, built Coinbase as a regulated on-ramp for buying bitcoin and later other digital assets. He has sold Class A shares under prearranged plans after converting Class B shares, which his filings show tranche by tranche.
Coinbase's share price drives the estimate. The option component adds leverage: a dollar move in the share price changes the intrinsic value of each option by a dollar.
Brian Armstrong's estimate declined mainly because Coinbase Global, Inc. shares decreased from the prior comparable close.
A one-day estimate change is not the same as income, profit, or a realized gain or loss.

Liabilities without a documented value are never shown as zero; they are simply not included, and that limitation is part of source coverage below.
100.0% of this profile's modeled gross value is supported by Tier 1 or Tier 2 evidence (primary filings, official documents, licensed market data, or audited accounts). The profile carries a strong coverage label.
The supported range shown in the header reflects documented uncertainty in privately valued components. Priced listed holdings carry no modeled range of their own. Unknown liabilities are not evidence that no liabilities exist. No personal liability is documented for this profile, so none is deducted.
The timeline runs from June 12, 2026 to September 4, 2026; the latest estimate is higher than the first point. Points before August 20, 2026 are labeled modeled reconstructions: today's reviewed ownership records applied to the closing prices of each earlier market date. Published history begins August 20, 2026 and grows one point per completed market date.
