Coinbase Insiders Set 10b5-1 Plans to Sell Up to 13.6 Million COIN Shares

On August 12, while most of crypto was still arguing about where Bitcoin would settle, Brian Armstrong signed a document that fixed, in advance, how much of his Coinbase stake he could sell. The arrangement sat inside a routine filing until October 29, when Coinbase’s third-quarter 10-Q report landed with the Securities and Exchange Commission. Item 5 of that filing discloses three pre-arranged trading plans covering up to 13,594,519 shares of Class A common stock across three of the company’s most senior figures: Chief Executive Officer Armstrong, co-founder and director Fred Ehrsam, and President and Chief Operating Officer Emilie Choi.
