13F stock ownership research
RBLX institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with RBLX and shows every matching position in SnowballHare's tracked 13F manager universe. It connects holder-level changes with four-quarter history and company research without presenting delayed filings as live ownership.
Deterministic analysis from filing data
RBLX holder activity in the latest 13F cycle
Institutional positioning in RBLX is visible through the named holders. 1 active managers reported $333.5M in aggregate value. ARK Invest is the largest tracked holder. The sample is too small for a broad concentration reading.
New, increased, reduced, and exited positions separate the moving pieces. Soros Fund Management made the largest measured share-count move at -100.0%. 1 manager exited, including Soros Fund Management. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
RBLX's ownership trend is more informative than one filing alone. Holder count is below the trailing average of 1.3. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
The final cross-check is to compare RBLX with similar company pages. Related ownership pages include AAPL, AXP, KO. Return to RBLX stock research for financial statements, earnings, and company risks.

Holder type breakdown
