Robotics has been around for decades, but the field is progressing faster than ever thanks to recent technological advancements, including artificial intelligence (AI). The largest robotics companies are spread across four unique sub-markets: industrial robotics, surgical robotics, warehouse robotics, and humanoids.
Companies are organized by robotics sub-market and ranked within their sub-market by the most relevant available metric. Metrics used were robotics-segment revenue for industrial robotics, installed base and procedure volume for surgical robotics, systems deployed for warehouse robotics, and units sold for humanoids. Robotics companies in different sub-markets can't be directly compared, since the most appropriate metric depends on the sub-market.
The industrial robotics market is large and growing, but the biggest players are Japanese and European. The top five by brand share at the end of 2024 were ABB (ABLZF +0.72%), Epson (SEKEY +0.20%), FANUC (FANUY -3.53%), Kawasaki (KWHIY +1.27%), and Yaskawa (YASKY -2.50%), according to data from Statista at the end of 2024. U.S. investors have limited options for direct investments in robotics companies.
While ABB had the largest robotics brand share, it sold its robotics division to SoftBank (SFTBF +1.38%) in 2025. It's still included in Statista's brand share data below, as that was taken in 2024.
Company | Brand share |
|---|---|
ABB | 13% |
Epson | 13% |
FANUC | 11% |
Kawasaki | 8% |
Yaskawa | 8% |
KUKA | 6% |
Denso | 4% |
Universal Robots | 4% |
Comau | 1% |
Other | 32% |
Here's a closer look at the "Big Four" robotics companies: FANUC, ABB, Yaskawa, and KUKA, as well as Teradyne (TER +2.02%), the owner of Universal Robots. All these industrial stocks have publicly available robotics-segment financials. Epson, Kawasaki, and Denso are also top robotics companies with sizable brand shares, but they aren't covered here because they don't report robotics revenue separately.
Based in Oshino, Japan, FANUC is the largest manufacturer of industrial robots and computer numerical control (CNC) systems. Its robot division generated 378.6 billion Japanese yen (about $2.4 billion) in sales in its FY2025. That accounted for 44.1% of the company's full-year revenue of 857.8 billion yen.
A Swiss company headquartered in Zurich, ABB was the world's second-largest producer of industrial robots. It agreed to sell its robotics division to SoftBank for approximately $5.4 billion in October 2025. ABB reported $2.3 billion in revenue from its robotics and discrete automation segment in 2025, 7.0% of its total revenue that year of $33.2 billion.
Yaskawa is a Japanese robotics company with three business segments: motion control, robotics, and systems engineering. Its robotics segment, which includes sales of industrial robots, generated revenue of 247.0 billion yen (about $1.5 billion) in FY2025. That was 45.9% of its full-year revenue of 537.7 billion yen.
Founded in 1898, KUKA is one of the world's oldest robotics companies. It's based in Augsburg, Germany, and is now owned by China's Midea Group. KUKA's robotics segment generated revenue of about 1.0 billion euros (about $1.2 billion) in 2025, 25.9% of its total revenue of 3.9 billion euros.
Teradyne is an American semiconductor company based in Massachusetts, but it also became one of the leading robotics companies through a pair of acquisitions. It purchased Universal Robots in 2015 and Mobile Industrial Robots in 2018. Robotics makes up a smaller portion of Teradyne's sales. In 2025, its robotics segment generated $308.3 million in revenue, which was 9.7% of its total revenue of $3.2 billion.
The country at the top of the list for robot usage in manufacturing is South Korea, according to 2024 data on robot density in manufacturing from the International Federation of Robots (IFR). South Korea has 1,220 robots per 10,000 manufacturing employees. The U.S. ranks eighth by this metric, with 307 robots per 10,000 manufacturing employees.
China has significantly more annual robot installations than any other country. The IFR reports that China installs 295,000 units per year, more than twice as many as the next four countries combined (Japan, the U.S., Germany, and India).
The electrical/electronics and automotive industries have the most annual robot installations, but the numbers have been shifting recently. Both industries saw their annual robot installations decrease from 2022 to 2024, according to IFR data. General industries and metal and machinery, on the other hand, recorded growth in their annual industrial robot installations over the same time period.
Surgical robotics is the one sub-market where U.S. companies dominate, led by Intuitive Surgical (ISRG -1.69%), one of the top medical device stocks. It develops, manufactures, and markets the da Vinci surgical system, its flagship product, and the Ion robotic bronchoscopy platform.
In 2025, Intuitive Surgical reported that:
Intuitive Surgical has established a wide moat due to its installed base of systems and recurring revenue model. It has three segments: systems, instruments and accessories, and services.
Systems are product sales of its da Vinci and Ion systems. Instruments and accessories are consumable items used during every procedure, and services include maintenance, training, and support. The instruments and accessories segment and the services segment both generate recurring revenue, and, crucially, recurring revenue increases as the installed base grows. Here's how much revenue each segment contributed in 2025.
Segment | 2025 Revenue |
|---|---|
Instruments and accessories | $6.0B |
Systems | $2.5B |
Service | $1.6B |
Total | $10.1B |
Warehouse robotics is growing rapidly as retailers use robots to manage and distribute inventory at reduced costs. However, this sub-market offers few robotics companies to invest in.
The market leader is Amazon Robotics, formerly Kiva Systems, a subsidiary of Amazon (AMZN -0.94%). Investors can buy shares of Amazon, but because of its scale, robotics are a small part of its business, especially compared to retail sales and Amazon Web Services (AWS).
Symbotic (SYM +2.15%) is the top pure-play warehouse robotics company that's publicly traded. Revenue jumped 25.7% year over year to $2.2 billion in its FY2025, but Symbotic has customer concentration risk, as 85% of that revenue and a significant majority of its $22.5 billion backlog come from Walmart (WMT -0.39%).
Zebra Technologies (ZBRA -0.95%) previously had a warehouse robotics business, which it sold to Skild AI, a private company, in April 2026. While Zebra could still serve as a broader automation investment, it no longer provides warehouse robotics exposure, another indicator of the few publicly traded companies in this industry.
Humanoid robots, or "humanoids" for short, are an emerging technology with limited adoption and investability so far. Of 14,668 estimated humanoid shipments in 2025, 88% (12,686) were from Chinese companies. The only publicly traded U.S. company manufacturing humanoids is Tesla (TSLA +0.68%), which shipped 150 Tesla Optimus humanoids in 2025.
Morgan Stanley (MS -0.47%) forecasts that humanoid adoption will be relatively slow until the mid-2030s, then ramp up in the late 2030s and 2040s as technology advances and societal support grows. One potential accelerator is the convergence of physical AI and humanoids, with AI companies using LLMs as the brain for humanoids.
Although robotics stocks are often grouped together, robotics isn't one market. It's four distinct sub-markets, and no single company captures all four. All the sub-markets have different economics, timelines to widespread adoption, and leaders: FANUC and Yaskawa for industrial robotics, Intuitive Surgical for surgical robotics, and Amazon and Symbotic for warehouse robotics.
There's no clear market leader for humanoids yet, and the current leaders in terms of shipments are private Chinese companies. Investors who want early exposure could consider Tesla.
Here are the main robotics trends to watch going forward:
After a dip in 2024, global industrial robotics revenue rebounded in 2025, according to Statista. It's expected to make incremental gains through 2030.
Outside of Intuitive Surgical, Stryker (SYK -0.55%) is also established in surgical robotics, specifically orthopedic surgery, with its Mako system. However, Stryker doesn't report surgical robotics revenue separately, making it impossible to determine the size of this business segment. Medtronic (MDT +0.76%) is at the earliest commercial stage with its Hugo robotic-assisted surgery system, which received FDA clearance at the end of 2025.
