Nvidia Corp. (NASDAQ: NVDA) CEO Jensen Huang has projected a $50 trillion total addressable market for humanoid robots and physical AI. Huang has reiterated this figure across events such as Nvidia's GTC and the BG2 podcast, framing the automation of physical labor as an economic opportunity comparable to the impact of electric motors during the Industrial Revolution.
The article highlights that while GPUs serve as the brain of a robot, actuators function as the muscles. A single humanoid robot requires dozens of high-torque actuators for mobility and dexterity. As the industry scales from laboratory prototypes to factory floors, the focus is shifting to the specialized supply chain required to manufacture these physical components.
The article identifies four specific stocks that the author suggests are positioned to benefit from this hardware bottleneck:
- Moog Inc. (NYSE: MOG): The company provides actuation and precision motion control technologies for aerospace, defense, and industrial automation. Moog manufactures components such as fractional horsepower brushless DC motors and slip rings for advanced robotic systems.
- MP Materials Corp. (NYSE: MP): As a major supplier of rare earth elements, MP Materials provides the neodymium and praseodymium (NdPr) required to produce the high-performance NdFeB permanent magnets used in the traction motors and actuators of humanoid robots.
- Symbotic Inc. (NASDAQ: SYM): This company builds warehouse automation systems for major retailers like Walmart Inc. (NASDAQ: WMT). Symbotic utilizes autonomous mobile robots and integrated specialized actuators in its SymBot to actively pull heavy payloads into its center.
- KraneShares Global Humanoid Robotics and Physical AI Index ETF (NASDAQ: KOID): Launched to follow the MerQube Global Humanoid Robotics and Physical AI Index, the fund provides exposure to the entire ecosystem, including actuation systems and mechanical components. MP Materials is currently a top holding in this fund.
