Marketplace growth accelerates, but GAAP profits stay out of reach

01 Running thesis

Fast growth, not cheap

Xometry continues to gain momentum after a record Q2 2026. Revenue reached $229 million, up 41% year over year, marking the fourth straight quarter of accelerating revenue growth. The clearest win remains the Marketplace business, which grew 45% and pushed adjusted EBITDA to $14.1 million.

The bull case is simple. Xometry uses AI to price custom parts quickly, then matches buyers with suppliers that can make them. Recent AI upgrades improved cost prediction accuracy by 15%. As more buyers and suppliers join, the data gets better, quotes get sharper, and the marketplace scales with less cost added each time.

The Siemens collaboration adds a large possible channel. Siemens plans to embed Xometry's quoting and manufacturability tools into Siemens Xcelerator. This could put Xometry in front of many engineers at the point when they design parts.

The bear case still matters. The company continues to deal with the structural decline of its legacy Thomasnet services segment. Xometry acquired GoBRANDgo to help stabilize this unit, but integration brings execution risk. The founder CEO moving to Executive Chair adds transition risk. The stock also needs growth to stay high, because valuation remains a major pressure point.

Aug 2026Q2 2026 delivered a fourth straight quarter of accelerating revenue growth. Total revenue hit $229 million, adjusted EBITDA reached $14.1 million, and the company acquired GoBRANDgo to support its Services segment.
May 2026Q1 2026 strengthened the growth and operating leverage case. Revenue grew 36%, Marketplace revenue grew 40%, and adjusted EBITDA reached $10.5 million.
May 2026The Siemens collaboration added a major possible growth channel, but the page treats it as unproven until Xometry shares adoption metrics. The planned CEO transition also adds a new watch item.
Feb 2026The 2025 Form 10-K showed Xometry's first full year of positive adjusted EBITDA at $18.5 million. The same filing kept the bear case alive with a $61.7 million GAAP net loss.
Nov 2025Q3 2025 showed Marketplace revenue growth of 31% and adjusted EBITDA of $6.1 million. The quarter gave more support to the view that the marketplace can gain leverage as it grows.
May 2025Q1 2025 marked Xometry's first positive adjusted EBITDA quarter at $0.1 million. It also showed that Services revenue was still declining, which remains a key risk.
02 Business model

A marketplace spread on custom parts

Xometry makes most of its money from transactions in its manufacturing marketplace. A buyer asks for a custom part, Xometry gives a fast quote, and then Xometry finds a supplier to make the part. The company earns the gap between what the buyer pays and what it pays the supplier.

That model can scale well, but it carries pricing risk. Xometry often commits to a buyer price before it secures the final supplier cost. If its quote is wrong, or if supply costs jump, gross margin can fall. New AI models aim to reduce this risk by predicting costs more accurately.

The smaller Services segment includes Thomasnet advertising and marketing, supplier financial services, and software like Workcenter. This business has useful supplier relationships, but revenue has been shrinking. Xometry recently bought GoBRANDgo to add AI automation to its marketing services and reverse this decline.

Tools for buyers and suppliers

Growth engine

Instant Quoting Engine

This core AI tool gives buyers fast pricing, lead times, and manufacturability feedback. Recent upgrades improved CNC cost prediction accuracy by 15%.

Growth engine

Manufacturing marketplace

Buyers can source CNC machining, injection molding, 3D printing, sheet metal fabrication, and urethane casting. This segment is the primary growth engine.

Option

Siemens Xcelerator integration

The Siemens collaboration aims to place Xometry quoting tools directly inside Siemens engineering software to create a low-cost customer channel.

Cash cow

Thomasnet and GoBRANDgo

Thomasnet offers supplier advertising and digital marketing. The July 2026 acquisition of GoBRANDgo brings new automation tools to help stabilize this legacy business.

Steady

Teamspace

Teamspace gives enterprise buyers collaboration tools for sourcing custom parts. It helps Xometry serve larger teams and procurement workflows.

Steady

Workcenter and financial services

Workcenter is cloud software for manufacturers, while financial services can help suppliers get paid faster. These tools help keep suppliers close to Xometry's marketplace.

Services6%declining

Based on Q2 2026 trends, the Marketplace segment drives approximately 94% of total revenue, while the legacy Services business makes up the remainder.

05 Risk factors

What could break the story

GAAP losses linger

High impact · Medium odds

Xometry is improving on adjusted EBITDA, but it still has an accumulated deficit. If GAAP profits stay out of reach, investors may lose patience with the growth story.

We watchWatch for a full quarter of GAAP net income, not only adjusted EBITDA.

Bad quotes squeeze margins

High impact · Medium odds

Xometry gives buyers prices before it always knows the final supplier cost. That creates a real spread risk. If the AI quote is too low, or if suppliers demand more, Marketplace gross margin can fall.

We watchWatch Marketplace gross margin to see if AI cost prediction upgrades protect profitability.

Acquisition integration stumbles

Medium impact · Medium odds

The company acquired GoBRANDgo to fix its shrinking Services segment. Buying companies brings integration challenges, and if the new assets fail to spark growth, it could drag down margins.

We watchWatch whether Services revenue returns to growth or continues its structural decline.

CEO transition slows execution

Medium impact · Medium odds

Founder Randy Altschuler is moving to Executive Chair, and a new CEO will take over. Leadership changes can shift priorities or slow decisions while the new executive learns the business.

We watchWatch the first full-quarter commentary from the incoming CEO and any change in growth targets.

Trade policy raises costs

Medium impact · Medium odds

Xometry faces uncertainty from global tariffs. Tariffs can raise supplier costs, disrupt supply chains, or make customers delay orders. That could hurt both demand and margins.

We watchWatch management comments on tariffs, supplier costs, and customer order delays.
06 Quick answers

In one breath

What does Xometry actually do?

Xometry helps companies buy custom manufactured parts online. Its AI quoting tool estimates price and lead time, then the company matches the order with suppliers in its manufacturing network.

How does Xometry make money?

Most revenue comes from the Marketplace segment. Xometry charges the buyer for a part and pays a supplier to make it, keeping the spread between the two prices.

Is Xometry profitable?

Xometry reached positive adjusted EBITDA of $14.1 million in Q2 2026. However, it still carries historical net losses, so the company has not fully crossed into standard accounting profit.

Why did Xometry buy GoBRANDgo?

The July 2026 acquisition adds AI and automation capabilities to Xometry's marketing services. The company hopes this will stabilize its legacy Thomasnet division.
