What stands out

Three officers sold more than 25% of vested holdings: Mark Reinstra (36% of holdings, $13.3M, 19% under a disclosed plan), Arvind Chakravarthy (57% of holdings, $10.0M, none under a disclosed plan) and Matthew Kaufman (44% of holdings, $8.4M, 39% under a disclosed plan).Mark Reinstra: largest sale, Feb 13, 2026 · Arvind Chakravarthy: largest sale, Feb 11, 2026 · Matthew Kaufman: largest sale, Feb 10, 2026

Five insiders sold shares but ended with larger stakes, because more shares came in than were sold: David Baszucki (sold 598K, 1.7% of starting holdings; 995K added), Naveen Chopra (sold 67K, 19% of starting holdings; 73K added) and Sean Buckley (sold 20K, 97% of starting holdings; 87K added), plus 2 more.David Baszucki: largest sale, Feb 10, 2026 · Naveen Chopra: largest sale, May 20, 2026 · Sean Buckley: largest sale, May 22, 2026

Percentages cover 14 of 16 officers and directors. Left out: Dennis Durkin and Jason Kilar (holdings couldn't be fully reconciled). Disclosed company stock is not an insider's whole wealth.

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 Roblox Corp CEO selling stock?

Yes. David Baszucki sold 598K shares ($43.5M, 1.7% of starting holdings) in the past 12 months, 41% of it under a trading plan disclosed in the filings.

Why are Roblox Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 46% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 46% were to cover taxes and 8% had no disclosed plan. A trading plan schedules sales in advance.

Are any Roblox Corp insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Roblox Corp insiders sell?

About 2.3% overall. As a group they ended with more shares than they started with. 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.

14 of 16 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (10 exactly, 4 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 14 of 16 officers and directors. Left out: Dennis Durkin and Jason Kilar (holdings couldn't be fully reconciled). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$106M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $106M across 1,508,055 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $48.9M · 46%

54%

The lighter segment is sales with no plan disclosed in the filing ($56.9M), including tax-related sales outside a plan.

No plan disclosed · $8.0M

Sales with no 10b5-1 plan and no tax reference in the filing. $4.1M of it is Arvind Chakravarthy. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Mark Reinstra, Feb 13, 2026

Taxes

$51.1M of sales (48.3%) cite tax obligations in their footnotes, $2.2M of them also under a plan. Example: Sean Buckley, Aug 20, 2026

Charitable gifts · 112K shares

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

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 uncertainty2 insiders whose holdings couldn't be fully reconciled

Dennis Durkin: holdings couldn't be fully reconciled (difference of 3,524 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +3,524 shares on May 28, 2026 (Direct). Filing, May 28, 2026

Footnote: "These securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock. 1/4th of the RSUs shall vest on each of August 20, 2026, November 20, 2026 and February 20, 2027, and the remaining 1/4th of the RSUs shall vest on the earlier of (i) the day before the annual meeting of stockholders held in 2027 or (ii) May 28, 2027, subject to the Reporting Person continuing as a service provider through each vest date. | A portion of these securities are Restricted Stock Units ("RSUs").

Footnote: "In connection with the vesting on February 20, 2026, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,125 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,125 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,125 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock. | A portion of these securities are Restricted Stock Units ("RSUs"). Each RSU represe"

Sources and methodology670 filings from SEC EDGAR, and how we read them

All 670 Forms 3, 4 and 5 filed for Roblox Corp (SEC CIK 1315098) from Mar 2, 2021 to Oct 6, 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".
