Highest Borrow-Fee Stocks Today: September 11, 2026 — Hard-to-Borrow Rates

TL;DR: As of 10:50 PM ET on September 11, 2026, BIAF carries the highest borrow fee in Tapeboard's market-wide ranking at 1035.8% annualized. ATPC ranks second at 640.3% and JZ third at 615.4% annualized.
The costliest name to borrow on a market-wide basis is BIAF at 1035.8% annualized as of September 11, 2026. Fees on today's list span 1.6% to 1035.8% annualized; the median is 11.4%. The borrow fee is the annualized cost a short seller pays to maintain a borrowed position, and ultra-high rates in the triple-digit range typically flag distressed, very-low-float, post-reverse-split, or recently listed names where shares are nearly impossible to locate in the lending pool — not conventional short squeeze setups. Today's top three, BIAF (1035.8%), ATPC (640.3%), and JZ (615.4%) as of September 11, 2026, all sit in that scarcity-driven category, where the fee reflects how hard the shares are to borrow rather than any directional signal.

Borrow-Fee Tiers
Tapeboard categorizes annualized borrow fees as normal (under 2%), elevated (2-10%), hard-to-borrow (10-50%), and extreme (above 50%). On September 11, 2026, 14 names on today's market-wide list fell in the hard-to-borrow or extreme tier. Seven of those — TC, RGC, GCTK, XPON, and the top three — carry fees above 100% annualized as of September 11, 2026, a range where holding a short position for even a few weeks becomes prohibitively expensive.
What a High Borrow Fee Signals
An annualized borrow fee is the stock-loan cost a short seller pays to keep a position open. A high fee reflects scarcity in the lendable pool — when few shares are available to borrow, the loan rate rises until supply and demand clear. It does not, by itself, predict a squeeze. Names with triple-digit fees are often distressed, very-low-float, post-reverse-split, or recently IPO'd stocks where shares are almost impossible to locate; high cost-to-short is not the same as squeeze potential. That is why the borrow fee is weighted 25% in Tapeboard's composite squeeze score, which also incorporates short interest, price momentum, and volume — see the methodology for the full breakdown.
