GOOGLAlphabet Inc. · Insider ownership research

Alphabet Inc. insiders sold $141M. How much of their stake is that?

Less than 0.1% overall. As a group they still hold 99% of their starting shares. The biggest individual seller, Sundar Pichai, sold shares equal to 10% of starting holdings, but more vested, so the stake grew.

What stands out

  1. Amie O'Toole sold 29% of vested holdings: 13K shares for $3.7M, all under a disclosed plan.Largest sale, Dec 15, 2025
  2. Tax withholding outweighed market sales: the company withheld $295M of officers' and directors' shares for taxes, against $141M sold on the open market. The largest was Sundar Pichai ($226M withheld).Largest withholding, Feb 6, 2026
  3. Two insiders sold shares but ended with larger stakes, because more shares came in than were sold: Sundar Pichai (sold 358K, 10% of starting holdings; 1.42M added) and Frances Arnold (sold 1.2K, 6.9% of starting holdings; 3K added).Sundar Pichai: largest sale, Mar 4, 2026 · Frances Arnold: largest sale, Jun 30, 2026

11 of 15 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (3 exactly, 8 with a minor or footnoted difference). For 4 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 10 of 15 officers and directors. Left out: John Doerr, John Hennessy, Marsida Saraci and Martin Chavez (holdings couldn't be fully reconciled); John Walker (most of their shares vested during the period, so a percentage would mislead). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$141M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $141M across 462,934 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Taxes

884,982 shares ($295M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 724 shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

Sources and methodology1,811 filings from SEC EDGAR, and how we read them

All 1,811 Forms 3, 4 and 5 filed for Alphabet Inc. (SEC CIK 1652044) from Oct 8, 2015 to Oct 2, 2026, retrieved from SEC EDGAR on Oct 7, 2026. Prices are the ones reported in each filing, often weighted averages. 104 filings were left out because Alphabet Inc. filed them as an owner of another company's stock.

Probable 20-for-1 stock split on or before Jul 15, 2022 (split date stated in a footnote). Splits aren't reported as transactions; 24 holding lines changed by exactly this ratio, so earlier share counts are restated.

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".
