Coinbase Director Marc Andreessen Sells $2.48 Million in Company Stock

Coinbase director Marc Andreessen sold 13,676 shares of Class A common stock on September 8, 2026, for a total of approximately $2.48 million. The transaction took place at a weighted average price of $181.14 per share and was conducted under a pre-established trading plan, according to a regulatory filing.

Understanding Rule 10b5-1 Trading Plans

The sale occurred pursuant to a Rule 10b5-1 trading plan that Andreessen adopted on June 5, 2026. These plans allow company insiders to set up predetermined schedules for selling stock. This process helps them avoid accusations of insider trading based on nonpublic information.

By establishing these parameters during an open trading window, executives liquidate portions of their holdings without requiring manual approval or specific timing decisions that regulators might otherwise scrutinize, as noted in previous market reports.

Andreessen’s Remaining Stake

Following the September 8 transaction, Andreessen retains an interest in the company through various entities. He continues to indirectly beneficially own 1,136,324 shares through the LAMA Community Trust and holds an additional 2,568 shares of record via AD Holdings, LLC.

This sale represents a planned reduction in his holdings, consistent with the structured nature of 10b5-1 agreements. The mechanism ensures that the divestment occurs regardless of market volatility or the release of internal corporate information, providing legal protection for both the director and the company.
