Coinbase Stock Slides as CEO Brian Armstrong Sells $550M in Shares

Brian Armstrong, CEO of Coinbase, has sold more than $550 million worth of Coinbase (COIN) stock between April 2025 and January 2026, totaling approximately 1.5 million shares across 88 transactions.

The sales were conducted under a pre-arranged Rule 10b5-1 trading plan, a mechanism designed to avoid insider trading concerns.

The transactions coincide with renewed pressure on Coinbase shares, which have declined roughly 28% in early 2026 amid softer crypto trading volumes and cautious revenue expectations.

Insider Sales Overview

Across the reporting period, Armstrong executed 88 separate trades under the structured plan. The most recent notable transaction occurred on January 5, 2026, when he sold 40,000 shares at an average price near $249, generating proceeds of approximately $10 million.

Despite the divestitures, Armstrong remains one of Coinbase’s largest shareholders, retaining an estimated $14 billion stake in company stock.

The trading plan was reportedly established in August 2025, well before the early 2026 downturn, suggesting the sales were pre-scheduled rather than reactive to recent market weakness.

COIN Stock Under Pressure

Coinbase shares are currently trading near $153.2, down significantly from a 52-week high of $444.65. The decline reflects multiple overlapping headwinds.

On February 12, both JPMorgan and Citigroup lowered their price targets on COIN, citing a less constructive crypto environment and modeling revenue below prior company guidance.

Investor caution has intensified ahead of Coinbase’s Q4 2025 earnings report scheduled for February 12, with consensus forecasts pointing to an approximately 20% year-over-year revenue decline.

Broader Market Context

The stock’s weakness also mirrors broader crypto volatility. A recent decline in Bitcoin prices has contributed to net withdrawals from spot Bitcoin ETFs, dampening sentiment across exchange operators whose revenues remain closely tied to trading activity.

While Armstrong’s sales were structured and pre-planned, their scale has drawn attention amid the stock’s decline. The near-term trajectory for COIN will likely depend on trading volume recovery, earnings performance, and broader digital asset market stabilization.
