Meet the robot stocks, and why every Big Tech giant is racing into physical AI

If 2024 and 2025 were about AI that thinks, the next chapter is about AI that moves. The buzzword is "physical AI," sometimes called embodied AI, and the simple version is this: take the same kind of models that power chatbots and put them inside a body, a humanoid robot, a warehouse machine, a surgical arm, a self-driving car. It is the hottest theme in tech right now, and every giant you can name is racing into it. Here is what is going on, and the robot stocks you can actually buy.

Why robotics is being called the next AI trade

The case is mostly about size. Nvidia (NVDA) CEO Jensen Huang, who has been right about a few things lately, calls robotics the company's second-biggest opportunity after AI and has floated a $40 trillion total market for humanoid robots and labor automation. Wall Street's long-range numbers are smaller but still enormous, and they disagree wildly, which tells you how early this is. Goldman Sachs pegs the humanoid market at about $38 billion by 2035. Morgan Stanley sees roughly $5 trillion by 2050 with 63 million robots in use, and Citi goes further at about $7 trillion. Venture investors are already voting with their wallets: robotics startups raised a record roughly $15 billion in 2025, and 2026 is running higher still. Nobody knows the real number. The point is that the people who fund this stuff think it is the next big platform.

The Mag 7 are already all in

This is not a fringe bet for Big Tech. Every one of the Magnificent Seven has a robotics play, and they break into two camps: the ones building robots and the ones building the brains.

• Tesla (TSLA) is the most aggressive. It stopped making the Model S and Model X in 2026 and is converting its Fremont, California car factory to build its Optimus humanoid, with a long-term goal of up to a million robots a year. Elon Musk says Optimus will become Tesla's most important product.
• Nvidia (NVDA) is the brains. It sells the chips and the software (its Isaac and GR00T platforms) that run a huge share of the world's robots, which is why it wins no matter whose robot succeeds.
• Amazon (AMZN) is the biggest real-world user, with robots already moving goods in its warehouses, and it backs Agility Robotics, the maker of the Digit humanoid.
• Alphabet (GOOGL) builds robot AI through Google DeepMind (its Gemini Robotics models) and has partnered with humanoid startup Apptronik.
• Microsoft (MSFT) is an early backer of Figure AI, the buzziest humanoid startup, which hit a $39 billion valuation in 2025 with Nvidia among its newer investors.
• Meta (META) set up a robotics group inside Reality Labs and wants to build the software and sensors that power other companies' humanoids, a sort of "Android for robots."
• Apple (AAPL) is the outlier, reportedly working on a tabletop home robot rather than a humanoid.

The robot stocks you can actually buy today

Here is the catch that trips people up: the famous humanoids are not stocks yet. What you can buy on the public market today is mostly the established, profitable "picks and shovels" of robotics, the companies that make the arms, sensors, and systems that automation runs on. These are real businesses, not lottery tickets.

• Intuitive Surgical (ISRG), about $403, the dominant maker of surgical robots, with more than 8,000 of its da Vinci systems installed in hospitals.
• Teradyne (TER), about $434, owns Universal Robots and MiR, two leaders in the factory "cobots" that work next to people.
• Rockwell Automation (ROK) and Zebra (ZBRA), the backbone of factory and warehouse automation.
• Cognex (CGNX), which makes machine vision, the "eyes" nearly every robot needs.
• Symbotic (SYM), around $41, an AI warehouse-automation company backed by Walmart.

The small caps: the most upside, and the most risk

This is where the big gains and big losses live: small, mostly unprofitable companies that can double or halve on a single headline. Treat them as speculative. The cautionary tale is in the group itself, Vicarious Surgical (RBOT) fell about 91 percent in a year and was pushed off the NYSE to the over-the-counter market. The names people watch:

• Serve Robotics (SERV), around $6, the Nvidia-backed sidewalk delivery robots used by Uber Eats.
• Richtech Robotics (RR), around $2, service robots plus its own humanoid, Dex.
• Palladyne AI (PDYN), around $6, autonomy software for robots and drones.
• Ouster (OUST), around $42, lidar sensors (the laser "eyes" robots use), the biggest and steadiest here.
• Kraken Robotics (KRKNF), around $4.60, a Canadian underwater-robot maker that has been a standout.
• Micro-caps for the brave: Nauticus (KITT) and Microbot Medical (MBOT) near $1 to $2, plus Hong Kong-listed humanoid pure-play UBTech (UBTRF).

The best names are still private, but doors are opening

The robots grabbing all the headlines, Figure, Agility, Apptronik, Boston Dynamics, China's Unitree, are mostly still private, which is the same problem we wrote about with Chinese chipmaker CXMT in our DRAM ETF piece: the leaders you most want are the ones you cannot buy. That is starting to change. A new fund, RoboStrategy (BOT), around $32, is built to hold a basket of private and pre-IPO robotics companies (it lists Figure and Apptronik among its targets), so one ticker gets you a slice of the names that are otherwise off-limits. And Agility Robotics, the Amazon-backed Digit maker, is set to go public through a SPAC merger under the ticker AGLT, which would make it one of the first true humanoid pure-plays on a U.S. exchange.

The bottom line: physical AI is a real shift, not just a slogan, and the smart money is treating it as the next leg of the AI trade. But it is years earlier than the AI software boom was, the valuations already bake in a lot of hope, and the purest bets are either still private or tiny and speculative. If you want exposure, the calmest way in is the established automation names, the cheapest lottery tickets are the small caps, and the closest thing to owning the famous humanoids is a fund like BOT or, soon, Agility. Just size it like the early, unproven bet that it is. For a map of how this connects to the rest of the AI trade, see our AI stock map.

Nothing here is investment advice. Prices and market caps are approximate and as of late June 2026, and they change every day. Small-cap robot stocks are especially volatile and can move double digits in a session. Do your own research.
