Tempus AI, Inc. Class A Common Stock

Every open-market purchase and sale reported by TEM officers, directors and 10%+ beneficial owners on SEC Form 4, which must be filed within two business days of the transaction. Sales often reflect scheduled 10b5-1 plans or tax withholding rather than a directional view, so read counts alongside the size and the filer.

TEM Insider Trading FAQ
Who are the insiders at TEM?

Are TEM insiders buying or selling?
Across the 50 most recent Form 4 filings for TEM, 0 were open-market purchases (code P) and 38 were sales (code S). Sales frequently reflect scheduled 10b5-1 plans or tax withholding rather than a view on the stock.
How current is TEM insider data?
Form 4 must be filed within two business days of the transaction, so this is close to real time. The most recent TEM filing is dated 2026-09-29.
How to read Form 4 activity

Form 4 reports a change in beneficial ownership by an officer, director or 10%+ holder, and must be filed within two business days of the transaction — so this is close to real time, unlike the 45-day-lagged 13F institutional data.

Transaction codes matter more than the raw buy/sell count. Code P is an open-market purchase — an insider choosing to buy with their own money, which is the signal most research treats as informative. Code S is a sale, but sales are frequently pre-scheduled under a 10b5-1 plan or cover tax withholding on vesting equity, so a run of sales often says nothing directional. Codes A and M are grants and option exercises rather than open-market decisions.

Full filing history and per-insider positions are on the TEM quote page; the site-wide leaderboard is on the insider transactions hub.
