Highest Borrow Fees on October 15, 2026
Fees are low across most of the board. GRRR at 14.0% and CHPT at 4.0% are the only two names above 2%. ASTS at 1.9%, USAR at 1.6% and TE at 1.3% follow. The remaining names sit at 0.5% or below, so cost of carry is not the main pressure on shorts today.
Top 5 Short Squeeze Names
1. RXRX — Squeeze Score 93.6
RXRX shows 30.8% short interest of float, and its float utilization reads the same 30.8%. The borrow fee is 0.5%, days to cover is 4.9, and the stock is on the threshold list at $4.16. Its 5-day momentum is +5.3%, so shorts are not sitting on a fresh gain. This is a threshold-flagged, high-short-interest setup in a low-priced stock. A positive catalyst would force covering against nearly five days of average volume.
2. CIFR — Squeeze Score 91.8
CIFR has 21.7% short interest of float, a 0.5% borrow fee and just 1.8 days to cover at $9.76. It is not on the threshold list, and 5-day momentum is -25.6%. The setup is a short base that can unwind quickly. With under two days of volume needed to cover, a reversal after the drop would push shorts out fast.
3. ASTS — Squeeze Score 90.7
ASTS combines 24.3% short interest of float with a 1.9% borrow fee, the highest fee among the top five. Days to cover is 3.9, 5-day momentum is -21.9%, and the stock is threshold-flagged at $43.37. This is a higher-priced name where fee pressure and sustained short volume overlap. If borrow availability tightens further or a positive catalyst arrives, the 3.9-day cover window is where pressure would show first.
4. HUT — Squeeze Score 90.3
HUT has the lowest short interest of the top five at 18.5% of float, with a 0.4% borrow fee and 3.1 days to cover. It trades at $76.09, is threshold-flagged, and has a 5-day move of -4.4%. The score here leans on how quickly the short base can be covered rather than on its size. A positive catalyst would need only about three days of volume to clear the shorts.
5. PRME — Squeeze Score 87.3
PRME shows 27.9% short interest of float, a 0.4% borrow fee and the longest cover time in the top five at 6.3 days. It is threshold-flagged at $3.61, with 5-day momentum of +0.8%. This is a slow-to-cover, low-priced setup with flat price action. If a positive catalyst forces covering, 6.3 days of volume means the exit stays crowded for longer than in the faster-cover names above it.
Stocks Flagged on the FINRA Threshold List
A T in the table marks a symbol with sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file, meaning more than 50% of recent volume was short-side within the last 7 trading days. Twenty of the 25 names carry the flag today. The five without it are CIFR at 91.8, TE at 85.6, BTDR at 81.5, IREN at 79.4 and CRBP at 75.9.
