Coinbase CEO Sold $550M in Stock Over 9 Months, Data Shows, as public records reveal that Brian Armstrong reduced his stake between April 2025 and January 2026.

The reported transactions total more than 1.5 million shares and come as COIN stock trades near the lower end of its 52-week range. The disclosures surfaced ahead of the company’s upcoming earnings report.

Armstrong Disposed of Over 1.5 Million Shares

Matthew Sigel, Head of Digital Assets Research at VanEck, shared data showing Armstrong sold about $545.7 million in Coinbase stock. The transactions occurred over a nine-month period and were based on Bloomberg pricing data. The cumulative total exceeded 1.5 million shares.

The largest single-day sale took place on June 25, 2025. Armstrong sold 336,265 shares at $355.37 per share. The value of that transaction exceeded $119 million based on the reported price.

Selling activity continued into early 2026. On Jan. 5, Armstrong sold 40,000 shares at $254.92 per share. Sigel’s post indicated that this was the most recent disclosed transaction.

COIN Shares Trade Near Lower End of 52-Week Range

Coinbase shares dropped 13.3% to $146.12 during the latest trading session, reflecting continued pressure on crypto-related equities. At the same time, Bullish shares declined 8.5% to $24.90, as broader market weakness weighed on digital asset exchange stocks.

Earlier this year, COIN traded as high as $262 on Jan. 14. The shares have since moved lower as broader crypto prices softened. The company is scheduled to report fourth-quarter and full-year earnings on Thursday.

Goldman Sachs upgraded COIN to a buy rating on Jan. 5. The bank set a price target of $303 and cited growth in non-trading revenue. In contrast, JPMorgan reduced its price target by 27% and pointed to lower trading volumes and slower stablecoin growth.

Net Worth Falls as Product Expansion Continues

A Bloomberg report stated that Armstrong fell from the Bloomberg Billionaires Index. His net worth declined from a July 2025 peak of $17.7 billion. The index estimates his current wealth at about $7.5 billion.

Most of Armstrong’s remaining fortune is tied to his 14% stake in Coinbase. The valuation of that stake has moved in line with the company’s stock price. The changes reflect public market pricing.

Cathie Wood’s Ark Invest sold more than $19 million worth of Coinbase shares as Bitcoin fell toward the $60,000 level. The firm reduced its position by 119,236 COIN shares across its exchange-traded funds, according to reported trade data. The move came during a period of broader market volatility that affected both crypto assets and related equities.

Coinbase continues to expand its product offerings despite market volatility. The company introduced “Agentic Wallets” designed for autonomous AI agents. According to Coinbase, the wallets allow AI systems to hold funds, send payments, trade tokens, and transact onchain.
