"% 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.

Sep 10, 2026John Raymond sold 2.4K shares ($90K) under a disclosed trading plan. That is 3.0% of the total stake held that day.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.

Common questions

Is the IonQ, Inc. CEO selling stock?

No. Niccolo de Masi reported no open-market sales in the past 12 months.

Why are IonQ, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 99% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 1% had no disclosed plan. A trading plan schedules sales in advance.

Are any IonQ, Inc. insiders buying?

Yes. 1 officer or director reported 2 purchases in the past 12 months (Form 4 code P, which includes private purchases).

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

About 3.8% overall. As a group they ended with more shares than they started with. The biggest individual seller, Rima Alameddine, gave up 19% 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 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (17 exactly, 0 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 16 of 18 officers and directors. Left out: Robert Cardillo (holdings couldn't be fully reconciled); John Raymond (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$7.1M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $7.1M across 149,090 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($93K), including tax-related sales outside a plan.

No plan disclosed · $93K

Sales with no 10b5-1 plan and no tax reference in the filing. $93K of it is John Raymond. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: John Raymond, Mar 12, 2026

Taxes

148,509 shares ($6.7M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (2 trades)

1 officer or director bought shares in this period, in 2 trades(Form 4 code P). Across all their filings on record there are 4 purchase trades.

5 years earlier · filings don't cover the whole year
n/an/an/a

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 uncertainty1 insider whose holdings couldn't be fully reconciled

Robert Cardillo: holdings couldn't be fully reconciled (difference of 72,520 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +77,520 shares on Feb 26, 2026 (Direct). Filing, Feb 26, 2026

Footnote: "The transactions reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on March 12, 2025 and amended on June 13, 2025."

Inferred rename: "See Note 2" is treated as the same holder as "Bernal Trust", because the old name was never reported again and the new one opened with the same balance (4,453 shares). Old name, new name

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

Sources and methodology245 filings from SEC EDGAR, and how we read them

All 245 Forms 3, 4 and 5 filed for IonQ, Inc. (SEC CIK 1824920) from Nov 13, 2020 to Sep 15, 2026, retrieved from SEC EDGAR on Oct 8, 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".
