Insider buying across the market

As of 2026-09-21, these are the largest open-market purchases by company insiders filed with the SEC, over the last 7 and 30 days.

Open-market purchases only, at the companies somebody has looked at recently.

Insider filings are ingested when somebody views a company’s own page, and nothing sweeps the rest of the market in the background, so this covers the companies that have been checked rather than every filer. Only transaction code P, an open-market purchase paid for, counts here: an award, an option exercise and shares withheld for tax all increase what somebody holds without being a decision to buy, and are not included.
