Changes are versus the prior saved settlement shown with each comparison. Short interest measures open short positions at a settlement date, not daily short-sale volume. Missing values are not reported; zero is a valid reported value.

Source and measurement context
SI % uses shares outstanding available at enrichment time, not historical shares-outstanding counts. It is not a percentage of float. Missing percentages remain not reported; no shares-outstanding lookup is performed on page render.
Settlement dates are not publication dates. Saved coverage is not exhaustive history. Short interest and days to cover do not establish intent or predict returns.
At settlement Sep 30, 2026, ONDS had 228,545,414 shares of reported short interest. SI % of shares outstanding is 39.2486%, using shares outstanding available at enrichment time, not historical outstanding counts or float. Compared with settlement Sep 15, 2026, the change was -8,559,284 shares and -3.6099%. Source: FINRA via Polygon; data updated Oct 13, 2026.
What is ONDS's days to cover?
At settlement Sep 30, 2026, ONDS's days to cover was 3.44 days. Days to cover compares short-interest shares with average daily trading volume. It is a reported ratio, not a prediction of how long positions will remain open. Source: FINRA via Polygon; data updated Oct 13, 2026.
When does ONDS’s short interest update next?
FINRA short interest follows a bi-monthly settlement cycle, meaning twice per month rather than daily. Reports are published after the settlement date, and this page updates after the reported data is collected and processed. Weekends, holidays, and publication or provider delays can affect availability. A specific next update date is not promised.
