View all 460 holding institutions

Across its top 20 institutional holders, RIOT's holder base skews toward low-concentration, high-turnover investors on average (avg. concentration score 15/100, avg. turnover score 51/100).

Notable Holders

RIOT ranks #1306 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

RIOT is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.

RIOT is a top-conviction position for Starboard Value LP — at 6.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in RIOT belongs to BlackRock, Inc., but the position matters far more to Starboard Value LP, who has 6.2% 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.

GAMMA Investing LLC has added to its RIOT position for two straight quarters, increasing it by $82.4K to reach $141.9K today.

Bison Wealth, LLC has trimmed its RIOT position for two straight quarters, cutting it by $3.0M while still holding $747.6K.

RIOT is down 2.5% today, but institutions show net buying of $1.8B this quarter — a divergence between today's price move and the underlying institutional flow.

Smart Money Convergence

RIOT 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.
