QuantumScape heads into its Q2 earnings release — due after the close today — with short sellers rebuilding positions at the fastest pace in months and the borrow market tightening to its most constrained level of the past year.
The short side of this trade has been active all month. Short interest has climbed to 18.1% of free float, up roughly 16% over the past 30 days and adding another 3.6% in just the last week. That brings the absolute share count above 102 million — a new high for the 30-day window in the data. The ORTEX short score has ticked higher every session this week, reaching 71.2, a reading that places QS in the bottom 4th percentile of stocks by short positioning rank. What makes the week's move more notable is the simultaneity: short interest and borrow conditions tightened together, rather than one leading the other.
The borrow market tells a particularly pointed story going into today's print. Availability has dropped to just 49% — meaning there is roughly one share still available for every two already lent out — down sharply from 94% at the start of July. That is the tightest the lending pool has been all year, matching almost exactly the 52-week low of 48.6% hit Monday. Cost to borrow has risen 46% over the week to 0.84%, still a modest rate in absolute terms, but the directional move confirms demand for borrows is picking up. Taken together, this is a lending market that has quietly shifted from accommodative to tight in under three weeks.
Options traders are telling a different story. Call interest has overwhelmed put positioning — the put/call ratio has dropped to 0.25, near the 52-week low of 0.25 set Monday, and almost a full standard deviation below its 20-day average of 0.28. That skew toward calls implies a segment of the market is positioned for an upside move on the print, or at minimum is not hedging for the downside. The divergence between a crowded short book and call-heavy options flow is the week's central tension: both cannot be fully right.
The Street has gone quiet on QS — the most recent analyst actions on record date from February, when Morgan Stanley and Evercore both trimmed targets while holding neutral-equivalent ratings, and HSBC upgraded from Reduce to Hold while also cutting its target. The mean price target from that vintage was around $8.60, well above the current $6.05 close but reflecting a pre-selloff view. The stock has fallen 25% over the past month alone, so those targets carry limited informational value without a refresh. On valuation, the price-to-book has compressed to 3.5x, down roughly a full turn over the past 30 days, as the share price has eroded. With negative earnings, EV/EBITDA, and no revenue, conventional multiples offer little anchor — the story remains entirely about technology progress and cash runway.
Insider activity adds a quiet but consistent note of caution. The company's co-founder and CTO Timothy Holme sold shares on three separate occasions since mid-May — at prices of $8.23, $9.30, and $7.28 — with CFO Kevin Hettrich selling alongside him in May, June, and again on July 2. Net insider sales over the 90-day window total roughly $8.1 million. These look like scheduled sales rather than a single large block disposal, but the pattern of consistent selling into any price strength is worth noting context heading into a catalyst event. Most recently Holme sold at $7.28 — around 20% above the current price — which frames how much the stock has given back since those transactions.
Close peer SLDP held up relatively well this week, down just 0.4%, while MBLY fell nearly 11% — the contrast underscoring that automotive technology names are trading on idiosyncratic factors rather than a common sector bid. What to watch after today's release: whether the lending market loosens as short sellers take profits on a beat, or whether availability tightens further if the print disappoints — the current setup, with availability near its annual floor and call positioning unusually elevated, makes the post-earnings move in borrow conditions at least as interesting as the price reaction itself.
