AIIO cost to borrow hit 223.5% on May 8. That is up 642% from 28.7% just one day earlier. The borrow market for this micro-cap robotics name effectively repriced overnight.
Availability has collapsed to near zero. With utilization at 93.28% — approaching its 52-week peak of 100% — almost every share in the lending pool is already out on loan. Only roughly one share remains available for every fourteen already borrowed.
Short shares jumped 81% in a single session to 514,514 on May 8. That follows a week-over-week gain of 69%. New short demand flooded in just as the lending pool ran dry. The result: a cost-to-borrow spike that wiped out months of stable pricing in one day.
For context, CTB had traded in a tight 24–45% band since late March. That corridor held for over six weeks. Thursday's jump to 223.5% is nearly 8x the top of that range.
The price action is the other side of this story. AIIO closed at $0.86 on May 8, up 46% on the day and 40% on the week. Short sellers caught in the rally needed to cover — or new bears pressed in expecting a reversal. Either way, borrow demand spiked.
The ORTEX short score sits at 59.9, with a combined score of 67.0. The utilization rank is in the 7th percentile across the market — meaning availability is tighter than 93% of tracked stocks.
Earnings are due May 27. Prior prints have moved the stock sharply: +28% and -21% in consecutive quarters last year.
