Notable Holders

MARA ranks #1404 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

MARA is a top-conviction position for Bitwise Funds Trust — at 5.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in MARA belongs to BlackRock, Inc., but the position matters far more to Bitwise Funds Trust, who has 5.5% 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.

California State Teachers Retirement System has added to its MARA position for two straight quarters, increasing it by $402.3M to reach $405.3M today.

Parallax Volatility Advisers, L.P. has trimmed its MARA position for two straight quarters, cutting it by $15.6M while still holding $31.2M.

Smart Money Convergence

MARA 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.
