Physical AI Stocks: The Companies Behind the Trend
Physical AI stocks are the companies whose products let artificial intelligence act in the real world: satellite constellations that connect devices anywhere, chips that link phones to orbit, sensors that let machines see, and robots that act on what they perceive. The term has been pushed into investor vocabulary by analysts including Josh Baylin, whose “Starphone” presentation for Stansberry Research argues that “Physical AI is going to be one of the defining wealth-building trends of the next few years.” This article maps the categories and names what is actually investable today. We break down that angle in our What Is Physical AI? Plain Terms, Real Examples piece.
The categories, and who plays in them
Satellite connectivity. The backbone of the device-side thesis. Starlink’s Direct to Cell service already lets ordinary phones text via satellite with T-Mobile, and SpaceX “bought exclusive-use, nationwide spectrum from EchoStar. For $17 billion.” The public-market plays are the chipmakers building satellite radios into phones: Qualcomm and MediaTek have both signed deals with SpaceX. Baylin’s free pick is Qualcomm (QCOM): “there’s a real chance it runs through Qualcomm’s satellite chip. I think the stock could easily double over the next few years.”
Orbital compute. SpaceX unveiled its AI1 compute satellite, “the wingspan of a Boeing 747,” generating “somewhere around 120 to 150 kilowatts of computing power” on sunlight alone. Google, per the presentation, “agreed to pay SpaceX $920 million a month for SpaceX computing capacity” through 2029, a contract worth more than $30 billion. Direct exposure is SpaceX itself, now going public through its IPO; indirect exposure runs through launch and component suppliers.
Satellite communications hardware. Baylin’s physical AI bonus report includes a “satellite-communications veteran” whose devices hikers, sailors, and pilots “have all relied on for years.” Companies with that profile include Garmin and Iridium; the report names its specific pick for subscribers.
Machine vision. The report also includes a company with “over twenty years allowing technology to ‘see’” - established vision specialists include Cognex; again, the specific name is subscriber content.
Robotics and autonomy. Tesla’s Optimus program and the broader humanoid push, which we have covered in our MAGI humanoid robots piece, plus autonomous vehicles, are the industrial expression of physical AI. The supplier chain here includes sensors, actuators, and the edge chips that run models on the device.
Edge semiconductors. The chips that run AI on the device rather than in a data center. Our Ambient AI edge stocks coverage from another publisher’s series maps this category in detail, including Lattice Semiconductor and QuickLogic.
Why supplier stocks are the vehicle
Baylin’s historical case is the smartphone: the device makers, Nokia, then Apple, made fortunes, but so did the supply chain. Motorola “quadrupled between 1991 and 1995”; Skyworks went “up as much as 491%”; Cirrus Logic “as high as 489%”; Amkor “as much as tripled.” His pitch applies the pattern to the physical AI wave: “I wouldn’t be surprised if early investors have the chance to make 50 times their money by the time Starphone launches, if you own the right stocks.” Those peak figures carry the standard disclaimer that they are maximum gains on best picks, which the presentation does include.
The logic has a real core: when a new device category ships, component suppliers get design wins years before the consumer brand captures the value, and their revenue scales with unit volume across every brand, not just the winner.
What to watch
Physical AI is not one catalyst but a staircase. Satellite messaging is live now; voice is rolling out; meaningful satellite data for phones is the next rung; a dedicated Starphone, Musk’s denials notwithstanding, would be the top rung. The FCC’s new rules making “satellite licensing faster and easier” and the roughly 15,000 next-generation Starlink satellites coming online each remove a constraint. Each rung that lands converts the theme from story to revenue for the suppliers above.
Considerations
The category is broad, which is both the appeal and the risk: “physical AI” can justify almost any tech holding, so discipline matters. Many of these businesses are cyclical semiconductors and industrials, not steady compounders. And the Starphone itself remains unconfirmed; Musk called the phone reports “utterly false,” while Baylin reads the trademark filings and spectrum purchase as the real signal. His framing: “a trillion-dollar company doesn’t jump over all these hurdles just for fun.”
