Coinbase chief executive Brian Armstrong speaks at the White House launch of the CFTC's innovation advisory committee, 19 August 2026. His Rule 10b5-1 plan filed in August lets him sell up to 8.17 million shares from 16 November 2026.

Brian Armstrong printed the best earnings headline of the quarter, then filed to sell about $1.3 billion of stock 23. Coinbase's−13.84% — Coinbase, down 13.84 percent today chief executive adopted a Rule 10b5-1 plan on August 12 to sell up to 8.17 million shares between November 16 and October 2027 23. That is the pre-set trading schedule an executive locks in while holding no inside information, which is why it can be disclosed weeks before the first sale. It is 2.2 times the 3.75 million shares his year-ago plan covered 2.

Co-founder Fred Ehrsam filed for up to 3.87 million shares and President Emilie Choi for up to 1.56 million 23. Together the three plans cover 13.6 million shares, about 6% of Coinbase's 223.7 million Class A shares, roughly $2.2 billion at Thursday's $160.59 close 2.

The $719 million is mostly a bitcoin mark

The same filing shows why the timing matters. Net income was $719 million, $2.51 a share, against forecasts of a loss 12. Under GAAP, the accounting standard whose rules let unrealized crypto gains into net income, about $715 million of that is a mark on the crypto Coinbase holds as an investment, worth whatever the tokens trade at next quarter 15. Adjusted net income was $78 million 1. Operating income, the profit from actually running the exchange, was $61.7 million, down from $480.5 million a year ago 2. Revenue fell 35% to $1.22 billion 1.

Those gains come from coins Coinbase owns, not fees from customers, and the coins' price answers to the Fed. Bitcoin rose 39% during the quarter 7. But the Fed held rates at 3.75% to 4% on October 28 in a 10-2 vote, with Governor Lisa Cook and Cleveland Fed President Beth Hammack dissenting for another hike, and traders put 82.6% odds on a December hike 6.

A hawkish Fed drains appetite for risky assets, the force that left COIN down 4.6% at $153.28 premarket on October 30, 57.6% below its $361.40 high, as the Binance breach hit the sector 5.

A $1.96 billion buyback is the only backstop for 13.6 million new shares

Each plan sells only above undisclosed price thresholds, and Coinbase permits insider trading only through these schedules 2. Armstrong himself says the market is turning, pointing to prediction markets that have passed $200 million in annualized revenue 1. Fair enough.

The proof is dated. Coinbase's $1.96 billion of buyback authorization is the only standing buyer of the supply, and the Form 4 filings, the SEC documents that reveal each insider sale after it happens, will show from November 16 whether the sellers clear their undisclosed price thresholds before the mark erodes 2.

Armstrong's new sale plan is 2.2 times the one he filed a year ago
