Brian Armstrong sold about $550 million in Coinbase stock
coinbase ceo brian armstrong sold approximately $550 million worth of Coinbase Global (COIN) shares over the past year, according to Coinpedia. The disposals occurred across multiple transactions during 2025–2026.
The sales were executed under a pre-established Rule 10b5-1 trading plan adopted in August 2025, as reported by MEXC. Such plans allow executives to schedule trades ahead of time to help avoid conflicts with material nonpublic information.
Why it matters: Rule 10b5-1 trading plan and perception risk
Rule 10b5-1 is an SEC framework that permits insiders to set up pre-planned, formulaic trade instructions when they are not in possession of material nonpublic information. Properly designed plans aim to separate personal liquidity needs from day-to-day company developments.
Even so, investor perception can still be sensitive when a founder-CEO sells large amounts during periods of volatility. Executives often cite diversification to manage concentrated wealth risk, which may reassure some shareholders but not eliminate scrutiny.
“It would be crazy after 13 years of building Coinbase to still have 99.999% of your net worth in one stock,” said Brian Armstrong, CEO of Coinbase.
Immediate impact: COIN stock performance and investor sentiment signals
At the time of this writing, COIN recently closed at $165.12 and traded at $165.86 after hours, with year-to-date performance down 26.98%, based on data from Nasdaq. The stock remains volatile alongside broader crypto market moves.
Investor focus has turned to upcoming earnings and target cuts from some banks, with bitcoin’s swings shaping trading sentiment, as reported by The Cryptonomist. Insider selling headlines can amplify these signals, though causation is difficult to isolate.
Institutional positioning shows mixed signals. For example, Caisse des Dépôts et Consignations disclosed purchasing 6,251 COIN shares, according to DefenseWorld, a single data point that does not establish a trend.
What Rule 10b5-1 means for insider sales scrutiny
How Rule 10b5-1 plans work in practice
Under Rule 10b5-1, insiders can adopt written instructions that specify trade dates, prices, or quantity formulas. Once active, trades execute according to the plan regardless of subsequent corporate developments.
These plans are intended to demonstrate that sales are not timed around undisclosed events. Companies commonly disclose adoption dates to show when instructions were set relative to later trades.
Why pre-planned trades can reduce, not remove, concerns
Pre-planned sales can lower legal risk by evidencing advance intent, but they do not eliminate market skepticism. Large, repeated insider sales during drawdowns often pressure sentiment, as reported by Coingape.
