Consider a situation where a company’s CEO decides to sell part of their stock holdings, while other senior executives make similar arrangements. This decision may come into the limelight among other shareholders, especially if the transactions are worth millions of dollars of the firms’ stocks.
Nevertheless, the time, terms, and circumstances that govern these plans are equally important as the amount. This was evident after a recent revelation by Coinbase, in which three of its top officials might be selling their stocks.
Coinbase CEO Brian Armstrong, along with co-founder Frederick Ernest Ehrsam III and President Emilie Choi, has developed trading plans for a maximum of 13,594,519 shares of Coinbase, with an approximate value of $2.2 billion at the closing price of COIN on October 29.

These trading plans were developed in the quarter ended on September 30, 2026, and implementation of the same is scheduled to begin from November 2026 to 2027. Nonetheless, these are hypothetical trades and not executed trades, which makes it very important for us to understand what Rule 10b5-1 permits.
What a Rule 10b5-1 Plan Means?
A Rule 10b5-1 plan is a prearranged trading arrangement that establishes instructions for transactions in a company’s securities. Those instructions are set before transactions take place and can specify the shares, timing and conditions for sales. Coinbase’s filing describes the plans as frameworks for potential transactions by Armstrong, Ehrsam, and Choi.
Coinbase says its directors and officers must conduct trades in company securities through these plans. Their adoption therefore reflects the company’s stated trading procedure. The filing indicates that there was no indication from the executives that this arrangement was adopted in response to a stock price movement or a business development event.
A deal is not a sale yet. Its adoption does not mean every share covered will be sold. The filing provides estimated periods and conditions and says those periods may end earlier if specified transactions are completed or certain events occur.
How Many Shares Could Coinbase Executives Sell?
The Armstrong plan relates to up to 8,167,446 shares related to the exercise of vested stock options. The plan’s estimated sale period is from November 16, 2026, until October 22, 2027. The sale will be made if COIN attains certain price levels.
The Ehrsam plan concerns up to 3,866,620 Class A shares that are issuable after conversion of Class B shares owned by his living trust. This particular plan has the estimated time frame of December 7, 2026, to June 7, 2027.
Choi’s plan includes 1,560,453 shares with the estimated period of January 4, to December 31, 2027. It also covers an undetermined number of shares tied to future restricted stock unit awards. Coinbase’s combined 13,594,519-share figure excludes those additional shares.
The plans cover different types of equity: vested options for Armstrong, shares issuable through conversion of trust-held Class B stock for Ehrsam, and an arrangement that includes future restricted stock unit awards for Choi. That distinction matters when interpreting the combined amount.
Why the Timing and Conditions Matter?
The plans were adopted during the quarter ended September 30, 2026, while an open trading window was in effect. Their estimated execution periods begin later: November for Armstrong, December for Ehrsam and January 2027 for Choi. The timeline is disclosed, but it does not establish the executives’ individual reasons for adopting the plans.
Price conditions also limit what can be inferred. Armstrong’s and Ehrsam’s sales depend on COIN reaching predetermined thresholds. Choi’s plan includes an undetermined number of shares associated with future awards. Readers should not assume that all the maximum amounts will be sold.
Coinbase’s requirement that directors and officers use Rule 10b5-1 plans explains the mechanism through which these insiders are required to trade company securities. It does not reveal their personal motivations. The filing does not attribute the plans to a bearish view, a need for liquidity or any other specific reason.
What the $2.2 Billion Estimate Represents?
The approximately $2.2 billion valuation applies COIN’s October 29 closing price to the combined maximum of 13,594,519 shares. It is an estimate based on that reference price, not a confirmed amount of proceeds. The value of any completed transactions would depend on the prices and number of shares actually sold.
The filing of such information does not mean that the number of 13.6 million shares have been sold. It outlines potential transactions over estimated periods extending into 2027, subject to price conditions and other qualifications. Choi’s additional, undetermined future-award shares are not included in the combined figure.
