Is MARA heavily shorted?

By share count, yes: 100,753,792 shares on 30 September 2026, the 42nd largest position among actively traded US stocks. By days to cover, 2.21, it was below the 3.79-day median.

Has MARA short interest changed much?

Very little for a stock this widely shorted. The count has stayed between about 94 million and 114 million shares in every report since August 2025, and no single report moved it by more than 8.69%.

Is 22% short interest high?

Percentages such as 22% are calculated against the float, and FINRA reports no float figure, so the percentages quoted for MARA cannot be checked against the filing. FINRA’s own numbers for 30 September 2026 are 100,753,792 shares and 2.21 days to cover.

MARA Holdings (MARA) short interest: large and unusually steady

Few heavily shorted stocks move as little as MARA. In all 27 FINRA reports since August 2025, between 94,030,357 and 114,372,561 MARA Holdings shares were held short. The latest, for 30 September 2026, is 100,753,792, after two reports in a row of small declines.

That steadiness makes MARA a big but stable short position: the 42nd largest on this site’s high short interest list on 30 September. The low point came on 31 October 2025 and the high on 30 January 2026, when the count rose 8.69% in one report.

Days to cover has stayed in a narrow band too, from 1.30 to 3.06 days, because MARA trades heavily. In the latest report 45,611,745 shares changed hands a day, so the position equalled 2.21 days of trading, 3,256th of 4,468 by that measure.
