Xometry Options Spike on Eve of Q3 Print

XMTR carries a put/call ratio four standard deviations above its 20-day average into Tuesday's Q3 results, making it one of the most unusual options setups in its recent history.

The options market is flashing its most defensive reading in months. The PCR jumped to 0.30 on Monday against a 20-day mean of 0.13, a z-score of 4.27 that stands well above anything seen in recent weeks. For context, the ratio spent most of October below 0.13, barely registering demand for downside protection. The single-session shift is notable, and it stands out against a backdrop where short sellers have been retreating. Short interest has fallen roughly 13% over the past week to 7.6% of the free float, a meaningful unwind that began the week of October 20. Borrow costs remain low at 0.51%, and availability is ample at 243%, far from any squeeze pressure. The lending market is relaxed; the options market is not.

The stock's own trajectory adds context to that divergence. XMTR has gained 6% over the past week, against a median gain of roughly 1.9% for its closest correlated peers, a spread that reflects genuine momentum rather than sector drift. Over the past month the stock is down about 7% to $95.49, so the week's rebound has recovered some of that ground without fully closing the gap. The analyst community broadly remains constructive. JPMorgan assumed coverage in August with an Overweight and a $120 target, and Rosenblatt lifted its target to $120 in September, both sitting well above the current price. The mean consensus target of $112 implies around 17% upside from Monday's close. The dissenting note comes from Goldman Sachs and UBS, both Neutral, with Goldman at $104 and UBS at $95, essentially flat to the current price. The core disagreement is not about whether Xometry's marketplace model works but about whether the valuation already prices in execution. Bulls point to the 45% year-over-year Q2 marketplace revenue growth, the Siemens partnership embedding the platform into CAD workflows, and a path to 40%-45% marketplace gross margins. Bears emphasise macro exposure: tariffs, volatile manufacturing demand, and the risk that customer concentration in the top-200 account cohort pressures the long tail if enterprise spending tightens.

Ownership is worth noting on one specific point. Siemens itself appears in the top-15 holder list with just under 1.05 million shares added as a new position, reflecting the strategic dimension of that partnership beyond a commercial agreement. CEO Sanjeev Singh and CTO Raghavan Vaidyanathan both sold shares in early October under pre-arranged 10b5-1 plans, small in aggregate value (under $200,000 combined for the disclosed transactions) and structured well in advance, so the signal is limited. PRIMECAP remains the dominant external holder at roughly 11.6% of shares.

The Q3 print will test whether Xometry's marketplace growth rate held its trajectory after Q2's standout, and whether gross margin moved closer to the 40% milestone that underpins the bull case at current multiples.
