Brock Lawrence J, Chief People Officer at Coinbase Global (COIN), has filed 70 Form 4 transactions across the company’s stock, with a pronounced sell-side bias. Over the tracked period, his open-market sales totaled approximately $58.1 million, while he recorded zero purchases and zero acquisitions. The most recent cluster of activity came on May 22, 2026, when he executed seven separate "S" trades ranging from roughly $57,000 to $415,000, aggregating about $1.1 million in a single day. That followed a pattern established in February and November 2025, where he also sold in multi-tranche batches—for instance, four sales on February 24, 2026, totaling roughly $744,000, and six sales on November 24, 2025, worth about $812,000.
The transaction mix also includes mechanical and compensatory elements that do not reflect discretionary selling. On May 20, 2026, Brock exercised options (coded "M") at zero value and had shares withheld to cover taxes (coded "F") worth approximately $983,500. Similar option exercises and tax-withholding events occurred on February 20, 2026, alongside a grant (coded "A") on February 14, 2026. These are routine, non-market actions tied to equity compensation, not open-market decisions.
Within the open-market sales, the dollar values vary widely, from roughly $50,000 to over $415,000 per transaction, suggesting a systematic liquidation of vested shares rather than a single large disposition. The absence of any "P" purchases—the only code indicating conviction buying—reinforces a consistent one-way flow: Brock has been a net seller of COIN throughout the filing window, with no recent buying activity to offset the sell pressure.
