Insider buying on May 4, 2026

On May 4, 2026, 72 insiders at 48 companies filed 81 purchases reported on Form 4, worth $1.1B in all, with a median purchase of $83.9K. The largest was Volkswagen US-Holding, Inc., 10% owner of Rivian Automotive, Inc. / DE (RIVN), who reported buying 62,889,522 shares worth $999.9M. Officers accounted for 38 purchases, directors who are not officers for 30, and 10% owners with no board or officer role for 13. Chief executives and chief financial officers filed 21 purchases: Ackman William A, CEO & Chairman, Director, 10% owner of Pershing Square Inc. (PS); Cohen Jonathan H, Chief Executive Officer, Director of CIK 1959353; Florance Andrew C, President and CEO, Director of Costar Group, Inc. (CSGP) among others. 19 companies showed cluster buying, two or more insiders buying within 7 days, among them PSUS (8 insiders), SRAD (7 insiders), EPAM (6 insiders), CCFN (4 insiders). For 28 insiders of 72, this was the first purchase of that company's stock on our record. That is fewer than the 88 purchases filed on May 1, 2026. A Form 4 is due within two business days of the trade, so most of these purchases were made earlier in the week. Code P also covers shares bought privately from the company, so one large figure can be a negotiated placement rather than buying on the exchange.
