Insiders at 9 AI-related companies disposed of $7.39 billion in stock from May to October

Insiders at nine U.S.-listed AI-linked companies sold $7.39 billion in stock between May and October 2026, according to a Protos analysis of 282 Form 4 filings with the SEC. The companies include Nvidia ($NVDA), Oracle ($ORCL), Micron ($MU), Broadcom ($AVGO), AMD ($AMD), SanDisk ($SNDK), CoreWeave ($CRWV), Arista Networks ($ANET) and Astera Labs ($ALAB), spanning chip, networking and data-center names as well as AI model developers. The figure reflects aggregate insider dispositions rather than net selling, and because Protos did not disclose its selection criteria or a filing-by-filing list, the total and transaction count should be attributed to its tally. The scale of selling is notable given how concentrated AI-related equities have become in U.S. indexes and portfolios. What to watch next is whether the pace of disposals continues into the following reporting window and whether other data providers corroborate the aggregate.
