Across its top 20 institutional holders, ARKK's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 8/100, avg. turnover score 50/100).
ARKK ranks #837 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
ARKK is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
ARKK is a top-conviction position for Ascension Capital Advisors, Inc. — at 8.6% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ARKK belongs to Susquehanna International Group, LLP, but the position matters far more to Ascension Capital Advisors, Inc., who has 8.6% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.
Venture Visionary Partners LLC has added to its ARKK position for two straight quarters, increasing it by $5.7M to reach $23.2M today.
NFSG Corp has trimmed its ARKK position for two straight quarters, cutting it by $676.2K while still holding $33.9K.

ARKK 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 2026-09-30 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.
