Fermi Inc. finds itself in an unusual position this week: short interest is jumping sharply while the borrow market is simultaneously opening up — a combination that tells a story of growing bearish conviction meeting little resistance.
The most striking data point this week is the speed of the short build. Short interest climbed 35% in a single week to reach 4.8% of free float, adding roughly 7 million shares in just two sessions. That takes the position to around 29.7 million shares — notable, but the direction of travel is what matters here. For context, shorts were twice as heavy in mid-May, when SI topped 43 million shares, before unwinding sharply through late May. The current rebuild is fast, but it is retracing from a low, not breaking new ground.
What makes the short build more striking is that borrow conditions have stopped being a constraint. Through most of May, availability was near fully exhausted — hitting as low as 0.19% on May 14, meaning barely one share was available for every 500 already borrowed. That lending squeeze has now unwound completely. Availability has loosened to 145%, suggesting there are roughly 33 million shares freely available in the lending pool today versus almost none a month ago. Borrowing costs reflect the same relaxation: cost to borrow has fallen from above 2% in early May to under 0.7% now, the lowest level in six weeks. Options positioning offers no particular conviction either way — the put/call ratio of 0.49 is essentially flat on its 20-day average, with a z-score close to zero. Shorts are rebuilding into easy conditions, with no hedging urgency visible in the derivatives market.
The Street's view on Fermi has deteriorated meaningfully in recent months. The most notable move came from Evercore ISI on May 15, when the firm downgraded to In-Line from Outperform and cut its target from $20 to $11. That downgrade carries extra weight because FRMI closed Tuesday at $5.62 — well below even the revised Evercore target. The mean analyst price target of $20.75 is a significant data-consistency flag: with the stock trading below $6, this figure almost certainly reflects stale inputs from initiations in late 2025, when targets were set in the $27–$35 range. The more recent, actionable anchors are Evercore's $11 and UBS's April 1 cut to $8 from $30, which give a more realistic picture of where informed Street thinking has landed. All five remaining analysts still technically hold buy-equivalent ratings, but target compression from $30+ to single digits in the space of two months is a meaningful directional signal. Bears cite cash burn extending into at least 2027, no current revenue, and heavy reliance on third-party nuclear and natural gas infrastructure. Bulls point to long-term data center infrastructure upside and the company's secured power and water supply partnerships — though the bull case is explicitly a multi-year execution story.
On ownership and insider flows, the 90-day net is heavily skewed toward selling. The founder, Perry, sold 11 million shares in late March for over $56 million. The CFO and COO each sold close to $4 million worth across two days in early April. A second chief-level officer added fresh sales on June 3, albeit at a much smaller scale. The net insider position over 90 days comes to around $68.8 million of net selling. That is a material outflow by any measure, though it is worth noting that institutional holders James Perry (no relation declared to the founder in available data) and Miles Everson each added shares in the period, bringing some offset to the headline selling figure.
The next scheduled earnings event is August 14. The most recent print on May 21 produced a modest 1.6% day-one decline, followed by an 11.5% recovery over the subsequent five sessions — a pattern that fits the company's binary setup, where a weak immediate reaction gave way to a relief rally. With shorts now rebuilding quickly, borrow conditions fully open, and the stock down 15% on the week to $5.62, the key tension into the August print is whether the current short build continues to accelerate or whether, as in mid-May, it exhausts itself before the catalyst arrives.
