Coinbase insider sales face encore as shareholders sue again

Coinbase’s board may have thought Thanksgiving was for turkey, but a group of shareholders decided to serve up a derivative lawsuit instead.

Filed in Delaware, the complaint accuses CEO Brian Armstrong, board member Marc Andreessen, and other insiders of selling $4.2 billion in stock at allegedly inflated prices while keeping the market in the dark about internal issues ranging from weak anti-money-laundering controls to ongoing regulatory investigations.

Not Coinbase’s first brush with derivative drama

Coinbase is no stranger to lawsuits.

An earlier suit in claimed Armstrong, Andreessen, and others dodged roughly $1 billion in losses by offloading $2.9 billion of stock after the company’s 2021 direct listing.

In the latest filing, plaintiffs argue insiders prioritized their own wallets over the company’s future, using the direct listing structure — which allows immediate open-market sales — to maximize personal gain rather than raise capital for Coinbase.

Coinbase’s board disagrees, calling the sales “normal attempts to monetize long-held investments” and noting the company was “exceptionally well-capitalized” at the time. Still, plaintiffs are pushing back, citing conflicts of interest in the internal review, including a special committee member who’s an angel investor in more than 50 Andreessen Horowitz-backed startups.

In their 72-page rebuttal, plaintiffs argued the “insularity and patronage” of Silicon Valley made impartial evaluation of claims against Andreessen unlikely.

Whether this is another Silicon Valley soap opera or a serious call for accountability, Coinbase insiders are about to get a second helping of legal scrutiny — and shareholders are keeping the lights on.
