The share of each day’s reported trading that was a short sale. This is not short interest: most of it is market makers selling short to fill buy orders and buying back within the day, so a ratio of 30–50% is ordinary for a heavily traded stock and says little about how many shares are held short overnight.
Figures describe Biogen shares, not any token. As of Sep 15, 2026, from exchange short-interest reports and FINRA short-sale volume, via Massive. Short sellers borrow and sell the shares themselves; token holders are not lending theirs.
