Sky Quarry Inc. is emerging from one of the most dramatic short-interest spikes in its brief public life, with shorts unwinding at speed even as the stock trades down 67% from a month ago and an earnings date lands in less than a week.
Short sellers built an extraordinary position here. At the peak on May 1st, estimated short interest hit 53% of the free float — a level that is extreme by almost any measure for a micro-cap oil sands developer. That surge began around April 24th, when SI jumped from roughly 4.5% to over 30% of float in a single session. ORTEX flagged the spike in real time, with cost to borrow simultaneously running above 350–400% APR through late April and early May. The borrow market was deeply stressed. Over the past week that position has been aggressively unwound: SI now stands near 14% of float, down 68% from the week prior. Cost to borrow has eased to 259% APR — still extremely elevated by any normal standard, but well off the 502% peak logged on April 16th. The ORTEX short score, which peaked above 80 in the days when short interest was most extreme, has retreated to 76.9 — still in the top quartile of the universe, but directionally moving lower alongside the covering.
The borrow market has loosened alongside the covering, though it remains far from easy. Availability is tracking below its 52-week tightest levels — the 52-week peak utilization was 94.5%, hit on April 3rd; the current reading of 47% indicates roughly half the lending pool that was extended is still out on loan. That means shares remain scarce relative to normal, and any renewed short-selling interest would face friction to rebuild the position quickly. The combination of a still-elevated short score, a cost to borrow still north of 250%, and a float that saw 50%-plus short interest just two weeks ago means the covering dynamic has not fully resolved.
The fundamental catalyst for all of this activity is not hard to find. On May 4th, Sky Quarry issued a Request for Proposals seeking development partners for its ~180 million barrel oil sands resource at the PR Spring facility in Utah. That announcement, which the company had also flagged on April 29th, appears to have been the spark that lit the short squeeze — and also the initial driver of short interest, as traders debated whether the RFP reflected genuine commercial momentum or a speculative overhang on an unproven asset. Q1 results filed on May 15th showed EPS of -$0.65, an improvement from -$1.25 a year earlier, but revenue of just $383,000 against $6.3 million in the prior year period — a sharp decline that adds complexity to the development-partner pitch.
The earnings history underlines how volatile this stock can be around corporate events. The last two announcements produced a +18.9% one-day move and a +165% five-day move in November 2025 and March 2026 respectively, before the April print delivered a -27.8% one-day drawdown and a -36.3% five-day loss. The next scheduled event is May 22nd. Whether yesterday's Q1 release is treated as the catalyst for that date or whether a separate event follows, the stock's track record of large post-announcement swings in both directions is the essential context.
The ownership picture is thin. JPMorgan is the largest reported institutional holder at 7.5% of shares, though that filing dates to December 2025. Vanguard and Geode Capital hold positions of under 0.5% each. Jane Street added 37,298 shares as of March 31st. The holder count in the data totals just 18 registered institutions — confirming this is a retail-driven name where positioning flows tend to be fast-moving and amplified. With the May 22nd event approaching, the short score still elevated at 76.9, cost to borrow stubbornly high, and Q1 revenue well below year-ago levels, the key question is whether the covering of the past week represents a clean exit or a pause before the next positioning decision.
