Rezolve AI heads into the week with its most expensive borrow market in over a month — and a short position that has now grown for ten consecutive sessions since the September 1 earnings shock.
The borrow story is the sharpest development of the past week. Cost to borrow jumped from 13.7% annualised on September 7 to 65.9% by September 10 — a 450% move in five sessions. That brings it back to levels last seen in early August, before the pre-earnings normalization cycle ran its course. Availability has tightened in parallel, dropping to 19.5% of shares borrowed — meaning fewer than one share remains available for every five already lent out. That's 39% tighter than a week ago. The ORTEX short score now reads 78.6, up from 73.1 at the end of August and the highest level in the trailing 30-day window. Short interest itself has climbed to 41.4 million shares, or 13.8% of the free float — up 10.7% on the week and continuing the unbroken ascent that began when the earnings drop triggered a rapid re-accumulation. Every previous note in this series flagged the structural nature of the short overhang; the data since September 1 has only confirmed that view.
What's changed from the September 7 note is the cost signal. At that point, borrow had normalised to roughly 13-14% and was framed as elevated but not extreme. That framing no longer holds. The near-quintupling of borrow costs in five days, while short interest continues rising, points to a market where demand for new short positions is outpacing supply of lendable shares. Availability at 19.5% is tight but not at its 52-week floor — the lending pool reached near-zero earlier this year, so there is room for further deterioration. The combination of rising SI, rising cost, and tightening availability is the most charged the borrow setup has looked since early August.
Options traders tell a different story. The put/call ratio has drifted lower over recent weeks, reading 0.25 against a 20-day mean of 0.28 — slightly below average rather than defensively positioned. The z-score of -1.0 puts options sentiment modestly more bullish than normal. That sits in direct contrast to the borrow market: short sellers are paying significantly more to maintain and build positions, while the options market is not pricing additional downside protection. When those two signals diverge, the contrast itself is worth watching.
On ownership, CEO Daniel Wagner holds a 13.8% stake on his most recent Schedule 13D/A amendment, filed August 28 — down from 15.6% previously. That modest trim is worth noting: Wagner's institutional filing has now been amended four times, the most recent one moving in the same direction as short sellers. Alejandro Gonzalez, by contrast, raised his disclosed stake to 7.5% as of July 20, up from 5.7%. Neither position has moved since those filing dates. The activist register also shows Alyeska Investment Group cutting from 7.6% to 4.4%, and Citadel falling from 5.5% to 0.5% — both as of February 2026, so those exits are stale but structurally significant as a record of institutional departure from a larger stake. The disclosure caveat applies throughout: positions are as-last-filed around the 5% threshold and holders can exit without a subsequent filing.
The next earnings event is scheduled for October 6. The most recent print delivered a 19.4% single-day decline and a 20.1% five-day loss — the largest negative reaction in the available history. With short interest near its post-earnings peak, borrow costs re-spiking, and the October print now less than a month away, the question is whether the borrow market continues to tighten as the calendar compresses — or whether rising costs eventually force some covering ahead of the event.
