RBLX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Roblox (RBLX) put out its Q2 2026 shareholder letter on July 30, covering financial results for the quarter ended June 30, 2026, plus guidance for Q3 2026. This 8-K is essentially the formal filing that attaches that letter as Exhibit 99.1, with supplemental materials also posted on the investor relations site. One thing to flag: the filing itself doesn't include the actual numbers — revenue, user metrics, and so on are all inside the letter.
