Why this matters — Three distinct ORTEX data signals have converged simultaneously on KITT (Nauticus Robotics). Short interest has collapsed 83% in a week, yet utilisation hit 100% and cost to borrow has nearly doubled — a rare and contradictory alignment.
Short Interest Collapse Estimated short interest in KITT fell 83.4% over the past week to 619,056 shares as of April 24. That is just 4.5% of free float — down from roughly 28% seven days prior. In raw terms, short positions dropped from around 4 million shares to just over 600,000. The one-month decline stands at 86%.
Utilisation at Peak Despite the sharp reduction in shares short, utilisation hit 100% on April 23 — matching its 52-week high. It stood at just 87% one day earlier. As of April 24, utilisation remains at 97.1%. Every available share to borrow is effectively lent out.
Cost to Borrow Surging The cost to borrow rose to 49.4% APR on April 24. That is up 82% over the past week and 91% over the past month. A week ago, CTB sat near 27%. The acceleration is sharp and recent — the move from ~27% to ~49% occurred almost entirely between April 21 and April 24.
The ORTEX short score stands at 80.1 as of April 23 — a high reading. The utilisation rank sits at 0th percentile, flagging extreme tightness in available borrow. On the insider side, the most notable recent activity was a series of sells by Transocean Ltd., a 10% owner, in late November and December 2025 at prices well below current levels. Vanguard added 38,124 shares in its most recent filing (as of March 31, 2026), a modest but directional build.
The short interest history shows KITT carried 4–5 million shares short consistently from mid-March through April 20. The drop to sub-700,000 shares occurred almost overnight — between April 20 and April 21. That step-change pattern, combined with borrow costs rising simultaneously, suggests a covering event rather than a gradual unwind.
