Xanadu Quantum Technologies has reversed course sharply this week — the same shorts that piled in after earnings are now covering, and the stock has jumped 54% as they do.
The price move is the starting point. XNDU closed at CAD 24.78 on May 26, up 13.4% in a single session and 54% on the week. That follows a brutal month — the stock is still down 41% over the past 30 days — but the pace of the rebound is notable. The May 14 earnings release knocked the stock 7.9% and triggered a wave of short-building. That wave is now unwinding.
The short data tells the story clearly. Estimated short interest has collapsed 65% on the week, falling from around 1.8 million shares in mid-May to roughly 584,000 shares as of May 26. The prior note from May 20 captured the peak of that bearish build — shorts had risen nearly 20-fold from the 232,000-share level seen on May 8. The reversal since then has been just as swift. As a frame of reference, the ORTEX short score has dropped from 57–58 in mid-May to 52.3 now, signalling the squeeze pressure has meaningfully eased since the shorts were most crowded.
The borrow market has also normalised dramatically. Cost to borrow now runs at 10.6% — still elevated, but a fraction of the 940% peak recorded in late April and the 200–327% range seen in early May. That earlier extreme reflected a genuinely dislocated lending market, where almost every share in the pool was committed. Availability has loosened as well, running at 17.8% of short interest — still tight on an absolute basis, but well above the 1.86% floor hit in mid-April. For context, the 52-week peak availability was 98.2%, so the borrow market remains far from easy; the squeeze conditions that existed in late April and early May are not present today, but plenty of demand relative to supply persists.
The ownership picture adds texture. Christian Weedbrook holds 15.6% of shares, OMERS Administration Corporation 13.5%, and Georgian Partners 10%. Together the top three investors control nearly 40% of the stock. That structural tightness in the float — combined with a relatively small free float for a quantum computing name — helps explain why short squeezes can be violent and fast when they do materialise. The Lockheed Martin retirement trust appearing among holders is also a notable signal of institutional interest in the photonics approach.
What to watch next is the durability of the short covering. Shares short are back near the low end of the range seen through April (~500,000 shares), and availability has moved back into the tight-but-not-extreme zone. If the stock holds these gains without a fresh catalyst, the covering impulse fades — and any renewed attempt to rebuild short positions into a tighter float will again face the borrow constraints that made April so punishing.
