Has David Baszucki bought RBLX stock?
No open-market purchase of RBLX by David Baszucki appears in SEC's Form 4 data for trades between Jul 01, 2024 and Jun 30, 2026. Share grants and option exercises are not counted as purchases.
Are David Baszucki's stock sales planned in advance?
84% of the sales on record (127 of 152) were marked on the Form 4 as made under a Rule 10b5-1 plan, which fixes dates or amounts months ahead so the sale is not a reaction to that day's news. The rest were timed without one. Neither kind says where the stock is going.

From SEC's quarterly Form 3, 4 and 5 data sets. Company insiders like David Baszucki — SEC lists the filer as "Baszucki David", role President & CEO — must report a trade in their company's stock within two business days. Only open-market purchases (code P) and sales (code S) are counted; grants, option exercises and gifts are not.
