Coinbase CEO Brian Armstrong has sold more than $550 million worth of company shares over the past year, according to publicly available data.
Figures highlighted by VanEck’s Head of Digital Assets Research, Matthew Sigel, show Armstrong sold over 1.5 million Coinbase (COIN) shares between April 2025 and January 2026.
Key Share Sales Details

Despite the sales, Armstrong still holds an estimated $14 billion worth of Coinbase stock, keeping him one of the company’s largest shareholders.
Why Is Brian Armstrong Selling Coinbase Stock?
The sales were made under a Rule 10b5-1 trading plan. This is a legal framework that allows company executives to schedule stock sales in advance. The purpose of this plan is to reduce insider trading concerns by setting up automatic transactions ahead of time.
Armstrong adopted the trading plan in August 2025. Because the sales were pre-arranged, they were not necessarily based on short-term market movements. However, large insider sales can still create negative sentiment, especially when they happen during periods of stock price weakness.
Coinbase Stock Under Pressure
Armstrong’s stock sales come at a time when Coinbase shares have pulled back from earlier highs. On February 12, major banks, including JPMorgan and Citi lowered their price targets on COIN ahead of the company’s earnings report. Analysts pointed to softer crypto trading volumes and cautious revenue expectations.
The decline in Coinbase stock has also affected Armstrong’s personal net worth, reportedly pushing him off Bloomberg’s list of the world’s 500 richest individuals.
