Exchange-Wide Data Update
Nasdaq has released its official mid-month short interest report for the settlement date of September 15, 2025. The data shows that short interest in Nasdaq-listed securities totaled approximately 17.15 billion shares, an increase from the previous reporting period. The average days to cover for these securities has also seen a slight uptick, moving to 2.01 days from 1.97 days.
Market Context
This official exchange data provides a comprehensive, albeit lagging, view of the market's bearish positioning. While this report is published twice monthly, it remains the gold standard for verifying the total open short interest across the Nasdaq exchange. Investors should use this as a baseline to compare against more frequent, real-time estimates from platforms like Ortex or S3 Partners to identify where shorting activity has accelerated since the mid-month cutoff.
