Estimate

Current Assessment

Armstrong's fortune is concentrated in Coinbase, the public crypto exchange he co-founded and leads. Bloomberg listed him at $8.57 billion in May 2026 and calculated that he held a 14% Coinbase stake directly and through trusts. A smaller piece of the estimate comes from his reported NewLimit stake and cash from prior Coinbase stock sales. The estimate is sensitive to Coinbase's share price, so it should be read as a market-linked range rather than a fixed balance sheet.

Key caveats

The best wealth snapshot found was dated May 18, 2026, not July 1, 2026.
Gross stock-sale proceeds are not added separately because taxes and reinvestment are unknown.
No reliable public evidence was found for personal crypto wallets, real estate, or liabilities.

Evidence gaps

Latest SEC proxy ownership table and post-January 2026 Form 4 reconciliation.
Exact COIN closing price and diluted share treatment for July 1, 2026.
Detailed cash, debt, and private-asset disclosures.

Confidence

Medium confidence

78/100

The estimate is supported by available evidence, with meaningful assumptions and caveats.

Key Evidence Gaps

Exact July 1, 2026 COIN closing price tied to Armstrong's verified current share count.
Latest Coinbase proxy ownership table and all relevant 2026 Form 4 filings for Armstrong and The Brian Armstrong Living Trust.
Execution status of the August 2024 Rule 10b5-1 plan after the June 2025 Barron's report.
Bloomberg cash amount and tax assumptions underlying the May 18, 2026 benchmark.
Independent support for NewLimit valuation/stake beyond Bloomberg/PitchBook-derived funding-round treatment and NewLimit role/investor confirmation.

Public Caveats

Estimate is anchored to Bloomberg's May 18, 2026 wealth profile, not a fully refreshed July 1, 2026 holdings calculation.
Coinbase stock volatility and any later insider sales could materially change the estimate.
Gross stock-sale proceeds are liquidity context and are not added separately because taxes, reinvestment, and Bloomberg's modeled cash treatment are not fully visible.
No reliable public evidence was supplied for personal liabilities, real estate, or private crypto wallet balances.

Uncertainty Drivers

Coinbase stock is highly volatile and the strongest located wealth snapshot is May 18, 2026, not exactly July 1, 2026.
Accessible sources did not provide the full 2026 proxy ownership table or exact current share count in a directly quotable form.
Bloomberg's cash balance and tax assumptions are not fully visible in the accessible page.
The NewLimit stake is private, illiquid, and based on funding-round valuation data rather than a realized transaction.
Potential personal crypto holdings, liabilities, pledged shares, gifts, charitable transfers, and real estate were not verified.
