C3.ai reports fiscal Q1 results on September 2 against one of the most hostile short-selling setups in the software sector — with more than a third of the free float bet against the stock.
Short interest is the dominant story here. Bears hold 35.4% of the free float — a figure that has climbed roughly 8% over the past month and now sits near its highest level this year. That's not a crowded-but-fading trade; it's an active, growing one, with short positions adding through August even as the stock recovered 13% from its July lows. Yet the borrow market tells a subtler story: availability runs at roughly 203%, meaning shares to lend comfortably exceed those already borrowed, and the cost to borrow is just 0.53% — near the lowest level in three months. Bears are aggressive in size but face no squeeze pressure whatsoever heading into the print.
Options traders have reached the opposite conclusion from short sellers. The put/call ratio has dropped to 0.44, nearly two standard deviations below its 20-day average of 0.50 — making this one of the most call-skewed readings of the past year. That positioning reflects speculative demand for upside, not downside hedging. The divergence is sharp: short sellers are heavily net-short, while options flow leans bullish. Something has to give after the close.
The fundamental debate is equally fractured. Bulls point to federal business momentum — bookings in the defense and aerospace vertical reportedly grew 139% — alongside a restructuring plan targeting $135 million in annualised cost savings. The bear case is harder to dismiss: subscription revenue is contracting, the company slashed full-year guidance by roughly $51 million at the last print, and the stock fell 5.4% the following day, extending losses to 3.4% over the subsequent week. Most analysts remain cautious. DA Davidson and Morgan Stanley both carry Underperform and Underweight ratings respectively, with $7 targets well below the current $10.34. UBS holds a $12 Neutral and Wedbush remains the outlier bull at Outperform with a $15 target. The mean analyst target of $8.82 sits roughly 15% below where the stock last traded — a consensus that is structurally bearish even before accounting for the earnings risk. The ORTEX short score of 72 ranks in the 4th percentile for short positioning intensity across the universe, underlining just how bearish the data aggregate looks.
Price action has been constructive in the near term — up 5.6% on the week and 12.6% over the past month — while correlated peers like NOW gained 15.6% and PATH rose 12.7% over the same stretch, suggesting the move is more sector tailwind than company-specific re-rating. Thomas Siebel sold 139,500 shares at $9.61 on August 3, a discretionary open-market sale worth approximately $1.3 million, offering no obvious conviction signal on the upside. The print will test whether federal bookings growth is enough to bend the revenue trajectory — and whether that answer is sufficient to move 35% of the float off its short positions.
