Klarna Borrow Market Tightens as Shorts Build Ahead of November Print

KLAR heads into its November 18 earnings date with short sellers rebuilding positions, borrow availability drying up fast, and options traders turning more defensive than they have been in months.

The clearest tension in the lending market is availability. With every share in the pool now lent out, availability has dropped to 12.6%, down from 24.4% a week ago and a sharp reversal from the 45% range seen in late September. That is close to the tightest level on record for the past year, with the 52-week low availability hitting 1.4% at its most extreme. The move has come despite cost to borrow remaining subdued at 0.91%, down 55% over the past month. Borrowing KLAR is cheap for now, but the pool of available shares is shrinking rapidly, creating a squeeze risk if demand for new shorts continues.

Short interest reinforces the cautious read. At 9.5% of free float, the short position has grown roughly 6% over the past month, adding about 2.3 million net short shares. The pace has been steady rather than explosive, which suggests a methodical re-building of bearish positioning rather than a panic-driven pile-in. Options confirm the tilt. The put/call ratio has jumped to 0.91, more than two standard deviations above its 20-day average of 0.73, putting it among the more defensive readings of the past year. That combination, more shorts, tighter borrow, and heavier put demand, is the clearest sign yet that the market is bracing for November's results.

The Street's direction of travel has been downward since the August print. After the Q2 results, nearly every firm that weighed in trimmed its target. Morgan Stanley cut to $17 from $21 while holding Equal-Weight. Barclays moved to $16 from $20. UBS downgraded from Buy to Neutral and cut from $23 to $16. TD Cowen lowered again more recently, to $16 from $18, still carrying a Hold. The mean target across the panel is $19.25, which implies meaningful upside from the $13.15 close, but that gap reflects a consensus that has been walking targets lower rather than buying the dip. The bull case centres on the economics of Fair Financing, with GMV up 138% year-on-year and an implied $40 to $50 million uplift to transaction margin. The bear case points to rising provisioning costs, a FY guide that implies a second-half slowdown, and a business that has only recently approached GAAP profitability. The factor scores add some texture: KLAR ranks in the 96th percentile on 30-day EPS momentum and 94th on forward EPS growth, suggesting analysts have been revising estimates sharply higher even as targets come down. The short score rank sits in the bottom 3rd percentile, flagging it as a heavily shorted name on a relative basis.

One ownership note is worth flagging. CEO Sebastian Siemiatkowski bought 692,506 shares on the open market on August 26 at $14.37 per share, a $9.9 million discretionary purchase with no 10b5-1 plan attached. That filing is the most significant insider transaction in the past 90 days, and it came at a price above where the stock trades today. Sequoia holds 15.9% of shares and BlackRock added roughly 2.7 million shares through the end of September, so institutional demand at lower levels has been real. The CEO's buy has not yet stabilised the price.

The earnings history is the final piece of context. The August 2026 print produced a 24.5% one-day decline and a 26.9% five-day loss. The print before that delivered a 5.7% one-day drop followed by a 30.7% loss over five days. Every reported event in the data has seen the stock fall, and fall hard over the subsequent week. With November 18 now less than four weeks away, that track record is the backdrop against which the tightening borrow market and rising put demand should be read.

What to watch next: whether borrow availability continues its current trajectory toward the single-digit levels seen earlier in the year, and whether the CEO's August open-market buy attracts any follow-on insider activity ahead of the November print.
