RBLX institutional ownership: what the Q2 2026 13F filings show
None of the 59 funds tracked here holds ROBLOX Corp (RBLX) at 5% or more of its reported 13F portfolio. In these filings RBLX shows up as a smaller position, which is why this page has reported adds and trims but no table of high-conviction holders.
On the buying side, 2 tracked funds increased their RBLX position in Q2 2026. Ranked by the size of the position they now report, the list is led by Two Sigma Investments ($731 m) and ARK Investment Management ($352 m). On the selling side, 4 funds cut their position, led by Renaissance Technologies ($371 m), ValueAct ($171 m) and Sands Capital ($0). Sands Capital and Whale Rock Capital sold out of RBLX entirely. The dollar figures are the positions as reported at quarter end, not the amounts bought or sold — a 13F gives share counts on two dates, not the trades in between. Each list stops at 10 funds, so a count of 10 means 10 or more.
RBLX 13F: questions and answers
Which hedge funds own RBLX?
No tracked fund holds RBLX at 5% or more of its portfolio. The funds reporting the largest RBLX positions after adding in Q2 2026 are Two Sigma Investments and ARK Investment Management.
Which funds bought RBLX in Q2 2026?
Two Sigma Investments and ARK Investment Management. “Bought” here means the share count in the Q2 2026 filing is higher than in the one before.
Which funds sold RBLX in Q2 2026?
Renaissance Technologies, ValueAct, Sands Capital (sold out) and Whale Rock Capital (sold out). A fund marked as sold out reported no RBLX at all at the end of Q2 2026; the others still hold a reduced position.
How current is this RBLX 13F data?
It reflects positions on 2026-06-30, the end of Q2 2026. Managers have 45 days after quarter end to file, so the holdings shown are always between six weeks and four and a half months old; filings for the quarter ending 2026-09-30 are due by 2026-11-14. The page is rebuilt daily, so a late or amended filing is picked up when it reaches the SEC.
Is this every institution that holds RBLX?
No. It covers the 59 funds tracked on this site, and within those only positions of 5% or more in the holders table and the 10 largest moves on each side. Index funds, pension plans and thousands of other 13F filers hold RBLX too; a fund with a position between 0.5% and 5% of its portfolio appears in the adds and trims only if it changed its share count.

It is neither the total number of institutions holding the stock nor every fund we track that holds it — smaller positions, down to the 0.5% reporting floor, do not appear here. 13F carries up to a 45-day reporting delay and options are excluded. Values are as reported in the filing, not current market value. Insiders are counted, never named. The company name is EDGAR's own spelling.
