Xometry's AI-Native Marketplace Hits Inflection: Physical AI and Siemens Catalyze Record Growth

Record Results and a Fourth Quarter of Acceleration

Xometry reported a record Q2 2026, with revenue up 41% year-over-year to $229M and marketplace revenue accelerating to 45% growth. The company has now delivered four consecutive quarters of accelerating growth, driven by its AI-native marketplace. As CEO Sanjeev Sahni noted, “Our AI models are effectively optimizing conversion, buyer growth and market share gains.” — Sanjeev Sahni, Chief Executive Officer · 2026-08-04 The company also raised full-year guidance, expecting 33-34% revenue growth and adjusted EBITDA of $60-62M. This acceleration builds on the trajectory management flagged earlier this year: “Q4 was a great quarter seeing marketplace growth accelerate to 33% year-over-year.” — James Miln, Chief Financial Officer · 2026-02-24

This momentum is visible in the fundamentals: Total revenue has climbed 432% over five years, with Q1 2026 at $205M and the Q2 print of $229M representing a new high. Gross margin has held near 38%. The stock has responded powerfully, up 107% over the last 90 trading days, and even after pulling back from its July peak, remains far above its spring range.

AI Models: The Engine of Growth

The quarter featured significant AI model upgrades, including a new cost prediction model, an adaptive sourcing model, and a context-aware process recommender. These interconnected models span the entire manufacturing journey, from geometry to certifications to production outcomes. Sanjeev explained in Q&A: “We are actually more extensively mining that data to find behavior patterns... every part that gets produced helps make the next quote stronger.” — Sanjeev Sahni, Chief Executive Officer · 2026-08-04 This intelligence engine is improving conversion rates, driving active buyer net adds to a 10-quarter high (3,976), and expanding the number of accounts with $50K+ spend to a record 2,039.

We are in the opening innings of a digital transformation and our ability to capture this massive untapped opportunity gives us strong confidence in our long-term growth trajectory.

Physical AI: A New Demand Tailwind

Beyond the shift from offline to online, Xometry sees a new long-term catalyst in physical AI. In prepared remarks, Sanjeev highlighted: “The rapid growth of robotics, autonomous systems and defense platforms creates a new category of customers needing fast on-demand parts.” — Sanjeev Sahni, Chief Executive Officer · 2026-08-04 This theme is reinforced by the company's own keyword trajectory, where physical AI and related terms like autonomous systems and defense platforms have emerged as new high-momentum themes. Unlike some sectors, these are not boilerplate—they are directly tied to enterprise wins, including the robotics leader order involving 200 complex parts across 40 suppliers.

Siemens Integration: Infrastructure for the Future

The Siemens partnership, announced in May, is progressing as planned. The two teams are building a native integration that brings Xometry's manufacturability and pricing insights directly into Siemens Design Center. In the prior quarter's Q&A, Sanjeev described the opportunity: “we are truly integrating directly into the Siemens software as a native embedded solution... real-time data connectivity to the engineer who is designing their product and being able to price it right there in their flow.” — Sanjeev Sahni, President and incoming CEO · 2026-05-08 Management confirmed on this call that they expect the partnership to positively impact 2027 operating results, and already see customer curiosity driving conversations. This aligns with the broader market trend of product led growth as a strategy across industrial marketplaces.

Financial Discipline and a Path to Profitability

Despite intense growth investment, Xometry delivered record adjusted EBITDA of $14.1M in Q2, a $10.2M improvement year-over-year. CFO James Miln noted, “Our record results for the second quarter underscore the continued scaling and increasing efficiency of our marketplace.” — James Miln, Chief Financial Officer · 2026-08-04 Operating expense leverage continues to improve, with sales & marketing down 320bps as a percentage of revenue. The company ended the quarter with $517M in cash, bolstered by a June equity raise and the Siemens investment, providing ample firepower for "selective disciplined tuck-in M&A." The asset-light model is converting to cash flow: operating cash flow was positive $17M in the first half of 2026.

Why It Matters

Xometry is demonstrating that a digital marketplace can not only scale but also re-accelerate growth by embedding AI across every part of the funnel. The combination of a proprietary data moat, a rising physical AI tailwind, and a high-profile technology partnership position the company for an inflection in both revenue and profitability. The 107% stock surge in 90 days reflects growing investor conviction that this is not a cyclical blip but a structural shift. As the company approaches a $1 billion run rate, the next question is whether the buyer growth and self-service expansion in Injection Molding can sustain this pace into 2027.
