Updated September 9, 2026. US stocks with the highest short interest — the share of freely traded stock that has been borrowed and sold by investors betting on a decline. 644 US stocks carry a known figure.
High short interest is not a sell signal. It shows that others are betting on a fall — not that they are right. If the stock rises, the short positions have to buy back, and those purchases can push the price up further. That is a short squeeze.

This is how shorting works: whoever shorts has borrowed the stock and sold it — and to close the position again they must buy it back. So when short interest falls, shares are genuinely being bought back. Every stock page carries a chart of short interest day by day, along with the peak, the date of the peak, and the change over the last month.
Short selling is borrowing a stock, selling it, and hoping to buy it back cheaper. The half that matters most is the other one: to close the position you MUST buy the stock back. So when short interest falls, shares are genuinely being bought back.
Short interest is the share of a stock's free float that has been borrowed and sold by investors betting on a decline. At 9%, nine out of every hundred freely traded shares are sold short. Below 2% counts as low, above 10% as high, and above 20% is unusual.
As of September 9, 2026, 644 US stocks in the TradeDesk database carry a known short interest. The most shorted is Ramaco Resources, Inc at 66.68%.
No. High short interest means other investors are betting on a fall — not that they are right. In some cases it leads to a short squeeze, where the price rises sharply because the short positions are forced to buy back. Treat it as one data point among several, not a sell signal on its own.
Today's figure shows how many are betting against the stock right now. The trend shows which way it is going. Short interest that has been high and starts falling back means the professionals are buying shares back and closing their positions. Every stock page carries a chart of that trend.
Short interest comes from official filings via our data provider and is refreshed regularly. TradeDesk has stored the day-by-day trend since May 30, 2026, so the charts cover that period and grow longer each day. Figures above 100% of free float are filtered out as data errors.
