Highest yearly fee firstHow it is measured
Each fee is Interactive Brokers’ own: the yearly rate it charges to borrow the stock and the shares it has available to lend, from the file it publishes about every 15 minutes. It is one broker’s figure, the one published free; another broker’s can differ, and a fee can change within the day. Listed stocks are exchange-listed operating companies; funds and over-the-counter securities are left out.
Which stocks are hardest to borrow? At 6:39 PM ET on Nov 11, 2026, PicoCELA (PCLA) cost the most to borrow among exchange-listed stocks: 1,054% a year, with 10,000 shares left to lend. 891 listed stocks cost 10% a year or more.
What is the cost to borrow a stock? A short seller borrows the shares it sells and pays the lender a fee for as long as the loan is open, quoted as a yearly percentage of the shares' value and charged daily. At 10% a year, keeping $10,000 of stock borrowed for a year costs about $1,000. Most large stocks cost a fraction of a percent; a stock that many want to short and few lend can cost hundreds of percent.
What does a negative rebate mean? The rebate is the interest a short seller earns on the cash from the sale, less the borrow fee. When the fee is higher than that interest, the rebate is negative and the short seller pays the difference.
Each stock’s fee, day by day, is on its short-interest page. The most shorted stocks are the ones with the most shares sold short.
