Is Inhibrx Biosciences Heavily Shorted?

Inhibrx Biosciences Short Interest: Frequently Asked Questions
Inhibrx Biosciences has 3,393,511 shares short — about 23.06% of its shares outstanding as of Sep 15, 2026. This figure is the official biweekly short interest report, which lags the settlement date by about two weeks — the same convention every short-interest tracker uses. (Note: "% of shares outstanding" runs slightly below the "% of float" you may see on MarketBeat or Fintel, since float excludes insider-held and restricted shares.)
At 3,393,511 shares short and 408,480 shares of average daily volume, INBX’s days-to-cover is 8.31. Days to cover above 5 is elevated and worth watching — a sustained upside move could put visible pressure on the short side.
Short squeezes happen when heavily shorted stocks rally sharply, forcing shorts to buy back at higher prices. The classic warning signs are days-to-cover above ~5, rising short interest, and a catalyst that pushes price up. INBX currently meets the days-to-cover threshold. AltIndex tracks short interest alongside insider activity and sentiment — the same number reads very differently depending on what those other signals say.
The biweekly short interest figures come from NASDAQ’s official short interest report — the same source used by MarketBeat, Fintel, and Benzinga. The data is settlement-date-based, published twice a month, and lags about two weeks. For daily short-selling activity (a higher-frequency complement), see the short squeeze tracker.
