About this data
What it is
Short interest is the number of shares investors have sold short and not yet bought back. FINRA, which oversees US brokers, publishes it for every US-listed stock twice a month.
Who files it
Brokers report their customers' short positions to FINRA, which publishes the totals.
How current
Positions are counted twice a month, and FINRA publishes them about a week later, so the latest report never includes today's short selling.
Worth knowing
A high number can reflect bets that the price will fall, or hedges against other positions. Days to cover is shares short divided by average daily volume: roughly how many days of normal trading it would take to buy them all back.
Not to be confused with
Fails to deliver: shares that were sold but not delivered by the settlement date, from the SEC. The tables on this page have a Fails outstanding column with the balance on each report date.

All of this comes from public filings.

Most shorted in the latest report
Shares that brokers had failed to deliver and not yet delivered at the end of this settlement date, from the SEC. The figure is a running balance: all the shares that were still undelivered at the end of that settlement date, including fails carried over from earlier days. It is not the number of new fails that day, and the file does not say how old they are. The same fail is counted again on every day it stays open. The SEC says these numbers are not evidence of abusive or "naked" short selling, and are not necessarily the result of short selling. Fails have many causes, and most are cleared within days. A large balance in one stock is a reason to look closer, not a conclusion.Source
