Page Tyler, chief executive officer of Cipher Mining (CIFR), has filed 39 Form 4 transactions in the trailing period, all tied to a single company. The pattern is overwhelmingly one of disposition rather than accumulation: total open-market sales reached approximately $5.54 million, with zero open-market purchases or acquisitions reported. The most recent activity, a pair of sales on July 8 and July 9, 2026, accounted for the bulk of that figure—$2.38 million and $2.55 million, respectively—marking the only outright sales in the past several months.
The broader filing history is dominated by mechanical and non-discretionary events. A cluster of option exercises (coded M) on June 30, June 22, and June 16, 2026, were paired with large share withholdings (coded F) to cover tax obligations, including a $20.39 million withholding on June 22. Similar tax-related withholdings appeared on March 31, December 19, and December 15, 2025. These transactions, along with compensation grants (coded A) in February and December 2025 and a gift (coded G) in May 2026, do not reflect a directional bet by the executive. The only discretionary signal—the two July sales—shows a clear selling bias, though the dollar values are modest relative to the total value of shares handled through automatic withholdings.
