No officer or director trades were reported for the past 30 days. The most recent before that:

Aug 15, 20263 executives had 29K shares ($415K) withheld by the company for taxes (not a market sale). That is between 2.9% and 3.8% of each person's total stake held that day.

"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? Less than usual: about one-fifteenth of the 5-year average. 2 insiders sold; the average is 7 a year. Year by year

Common questions

Is the Trade Desk, Inc. CEO selling stock?

No. Jeffrey Green reported no open-market sales in the past 12 months.

Why are Trade Desk, 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 and 100% had no disclosed plan. A trading plan schedules sales in advance.

Are any Trade Desk, Inc. insiders buying?

Yes. 1 officer or director reported 4 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Trade Desk, Inc. insiders sell?

About 0.1% overall. As a group they ended with more shares than they started with. The biggest seller whose stake can be measured, Samantha Jacobson, gave up 33% of starting holdings. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

17 of 17 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (13 exactly, 4 with a minor or footnoted difference). Percentages cover 12 of 17 officers and directors. Left out: Kathryn Falberg (most holdings were last confirmed in 2021); Andrew Vollero, David Haddad, Nathan Olmstead and Penry Price (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$5.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $5.8M across 206,509 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $5.8M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.7M of it is Kathryn Falberg. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Kathryn Falberg, Mar 5, 2026

Taxes

94,168 shares ($2.2M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (4 trades)

1 officer or director bought shares in this period, in 4 trades(Form 4 code P). Across all their filings on record there are 11 purchase trades.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertaintyEvery officer and director reconciles

Every officer and director reconciles for this period.

Jay Grant: minor difference of 621 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Samantha Jacobson: minor difference of 622 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Tahnil Davis: minor difference of 622 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Inferred rename: "Fund" is treated as the same holder as "IAVS Fund I. The reporting person may be deemed to indirectly beneficially own the securities held by IAVS Fund I, but disclaims such ownership except to the extent of his pecuniary interest therein", because the old name was never reported again and the new one opened with the same balance (65,752,720 shares). Old name, new name

Inferred rename: "IAVS Fund I. The reporting person may be deemed to indirectly beneficially own the securities held by IAVS Fund I, but disclaims such ownership except to the extent of his pecuniary interest therein" is treated as the same holder as "IA Venture Strategies Fund I, LP", because the old name was never reported again and the new one opened with the same balance (40,752,720 shares). Old name, new name

Inferred rename: "Trust" is treated as the same holder as "Green Irrevocable Trust of 2015", because the old name was never reported again and the new one opened with the same balance (12,666,670 shares). Old name, new name

Inferred rename: "Green Irrevocable Trust of 2015" is treated as the same holder as "various family trusts", because the old name was never reported again and the new one opened with the same balance (12,666,670 shares). Old name, new name

Inferred rename: "of IA Venture Strategies Fund I, LP" is treated as the same holder as "IAVS Fund I. The reporting person may be deemed to indirectly beneficially own the securities held by IAVS Fund I, but disclaims such ownership except to the extent of his pecuniary interest therein", because the old name was never reported again and the new one opened with the same balance (65,752,720 shares). Old name, new name

Inferred typo: the share class "Class B Comon Stock" is treated as the same class as "Class B Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Paul Ross, 13,720 shares): old title, new title

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology742 filings from SEC EDGAR, and how we read them

All 742 Forms 3, 4 and 5 filed for Trade Desk, Inc. (SEC CIK 1671933) from Sep 20, 2016 to Sep 16, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 3-for-1 stock split on or before Sep 23, 2016 (first filing that shows post-split balances). Splits aren't reported as transactions; 28 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 10-for-1 stock split on or before Jun 16, 2021 (split date stated in a footnote). Splits aren't reported as transactions; 6 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".
