On September 28, Coinbase Global, Inc. fell 3.04% in pre-market trading, trading at 190.23 USD/share, with turnover of approximately $8.38 million.

On the news front, SEC filings revealed that Coinbase CFO Alesia J Haas sold 39,030 shares on September 21 at an average price of $205.24, totaling approximately $8.01 million, while Director Marc L Andreessen sold 6,838 shares at an average price of $205.05, totaling approximately $1.40 million. The combined insider sales exceeded $9.41 million. Following the transactions, Haas retained 345,376 shares and Andreessen held 1,132,054 shares.

Adding to the bearish pressure, the options market recently saw a notable bear put spread — buying $187.50 puts and selling $180.00 puts — signaling directional downside conviction. Separately, a $3.31 million bear call spread and dual call-selling combinations indicated institutional positioning for capped upside potential. Operational headwinds, including a platform service outage and a third-party security incident affecting the Wmtx-USD trading pair, have further eroded market confidence.
