Key Points Robotaxis are proliferating around the country, led by Waymo. Autonomous vehicles and robots could be a multi-trillion-dollar industry. Arm has earned significant market share thanks to its power-efficient CPUs. For nearly a decade, technologists and business titans have predicted that self-driving cars are on the verge of going mainstream. Tesla (NASDAQ: TSLA) CEO Elon Musk has been talking up his vision of a robotaxi network for more than a decade, despite relatively little to show for it. Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need. Continue ยป However, it now seems that the dream of self-driving cars is coming closer to reality. Alphabet's (NASDAQ: GOOG)(NASDAQ: GOOGL) Waymo, the industry leader, is now performing 500,000 fully autonomous rides per week in 11 cities. Tesla has begun offering a small-scale robotaxi network in Austin, Dallas, Houston, and the Bay Area, and has ambitions of rapidly expanding it. If robotaxis go mainstream, they could be a trillion-dollar industry as they threaten to upend the entire transportation industry. Tesla and Alphabet are the most obvious names in the space, but they're not the best choice to get exposure, in part because they are already huge companies, and Waymo or Tesla's robotaxis would have to grow exponentially to move the needle for their parent companies. However, there's one chip stock that's well-positioned to capitalize on the growth of robotaxis and the expected boom in robotics. That's Arm Holdings (NASDAQ: ARM), best known for its power-efficient CPUs, which make it a preferred choice in technologies such as autonomous vehicles and robots. What Arm is doing with Physical AI The vast majority of the semiconductor industry is focused on data-center chips, which
