Silicon Valley VCs Invest Billions in Robotics and AI

Silicon Valley investors are directing tens of billions of dollars into robotics and physical AI as they seek the next frontier beyond chatbots. Robotics and physical AI companies raised $33.4 billion globally in the first half of the year, exceeding last year's $28.7 billion total and up sharply from nearly $5 billion in 2020, PitchBook data showed. The surge reflects cheaper hardware, more capable AI models, labor shortages, and competitive pressure from China. Major deals illustrate the rush. Defense firm Anduril raised $5 billion in May, co-led by Thrive Capital and Andreessen Horowitz. Autonomous shipbuilder Saronic raised $1.75 billion in March, led by Kleiner Perkins. Software firm Skild AI, which builds control systems for multiple robot types, raised $1.4 billion in January led by SoftBank and said in June it had reached $100 million in annual recurring revenue from more than 60 customers. Physical Intelligence, developing AI models to command robots, raised about $1 billion in May, co-led by Situational Awareness and Lux Capital. Other founders driving activity include former Uber CEO Travis Kalanick, whose Atoms raised $1.7 billion in July; Rivian CEO RJ Scaringe's Mind Robotics, with $900 million this year; and former Cruise CEO Kyle Vogt's The Bot Company, which has raised at least $300 million. Large technology companies are also entering the sector. Nvidia has popularized physical AI, and OpenAI is advertising robotics roles with base salaries up to $500,000. Meta acquired robotics startup Assured Robot Intelligence and is testing robots in its data centers. Google has invested in humanoid maker Apptronik and is working with DeepMind. Tesla is pursuing its Optimus humanoid. Andreessen Horowitz raised a $1.1 billion Machine Age fund in August for AI infrastructure and robotics. The commercial prize is viewed as enormous because robots can address physical labor across manufacturing, logistics, construction, services and homes, a market Nvidia CEO Jensen Huang has described as a $50 trillion opportunity. Yet valuations have risen faster than deployment. Humanoid maker Figure AI was valued at $39 billion last year despite limited factory pilots, underscoring investor expectations that a general robot breakthrough is near. Veterans warn the hype may resemble the autonomous vehicle boom. Robots still face difficult challenges in collecting physical-world data, manufacturing durable hardware, maintaining machines and scaling reliability outside labs. Skild AI and Field AI have crossed $100 million in revenue, but many startups remain early-stage. Menlo Ventures partner Matt Murphy cautioned that abundant capital can create losses when companies grow without clear traction. The industry's central question is whether advances in dexterous manipulation and adaptable AI will arrive quickly enough to justify the billions now flowing into robotics.
