Coinbase Global Inc. executives and board members have adopted Rule 10b5-1 trading plans that permit the future sale of up to 13.59 million Class A shares, carrying an estimated notional value of $2.18 billion based on the October 29 closing price of $160.59.
Insider Sales Schedules and Share Distributions
According to documents deposited with the SEC, Chief Executive Officer Brian Armstrong adopted his trading arrangement on August 12. His plan permits the sale of up to 8.1 million shares tied to the exercise of vested stock options, with transactions scheduled to kick off around November 16, 2026, and continue through October 22, 2027, subject to price thresholds in the arrangement.
Board member Frederick Ernest Ehrsam III entered into his trading plan on September 4. It covers up to 3.8 million Class A shares issuable when Class B shares held by his living trust are converted, with sales expected to run from December 7, 2026, to June 7, 2027. Coinbase President and Chief Operating Officer Emilie Choi adopted her arrangement a few days after Ehrsam. Her plan covers just over 1.5 million shares, including owned stock, equity awards, and assets in a trust co-managed by her spouse, with sales scheduled between January 4, 2027, and December 31, 2027.
Q3 Earnings and COIN Stock Movement
The insider filings coincided with Coinbase releasing its Q3 2026 financial report, which showed net income of $719 million ($2.51 per share), up from $432.6 million ($1.50 per share) in the same period a year earlier. Total operating expenses between July and September dropped 17% to $1.15 billion from $1.39 billion in Q3 2025.
However, transaction revenue fell 43% to just over $590 million, down from $1.05 billion a year prior. Growth in prediction markets provided a partial offset, generating over $200 million in revenue. Together with derivatives, prediction markets made up at least 25% of total transaction revenue, while subscriptions and services accounted for 49%. The surge in prediction activity reflects broader industry shifts, as platforms like DraftKings launch prediction apps across the market.
Coinbase stock (COIN) closed at $160.59 before falling almost 5% to $152.98 in after-hours trading. The stock remains down at least 56% from its recent peak.
Key Takeaways
- Brian Armstrong, Frederick Ernest Ehrsam III, and Emilie Choi filed plans to sell up to 13.59 million Class A shares worth $2.18 billion.
- Execution dates span from November 2026 through December 2027 under pre-scheduled SEC Rule 10b5-1 plans.
- Coinbase Q3 2026 net income grew to $719 million, though transaction revenue plunged 43% to $590 million.

Why It Matters
Rule 10b5-1 trading plans allow corporate insiders to schedule equity sales years in advance, protecting executives from potential insider trading allegations. While these scheduled liquidations do not signal immediate market panic, the long execution window extending into late 2027 highlights how top leadership is managing personal equity liquidity. As core transaction fees shrink and non-trading segments like prediction markets expand, investors will carefully watch whether Coinbase's diversification can stabilize earnings before these heavy insider share liquidations begin.
