Common questions

Is the Alumis Inc. CEO selling stock?

No. Martin Babler reported no open-market sales in the past 12 months.

Why are Alumis Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 25% were to cover taxes and 75% had no disclosed plan. A trading plan schedules sales in advance.

Are any Alumis Inc. insiders buying?

Yes. 1 officer or director reported 18 purchases in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

Sources and methodology108 filings on record, 41 filed in the 12-month period, and how we read them

All 108 Forms 3, 4 and 5 on record for Alumis Inc. (SEC CIK 1847367), filed from Jun 27, 2024 to Sep 9, 2026; 41 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
