Catalyst Investors flags risks in physical AI funding surge toward robot software
XLK•Physical AI raised $47.4 billion in the first half of 2026, nearly four times the previous six months. Catalyst Investors favors revenue-generating robotics operators over robot-model developers, citing unproven competitive barriers and deployment challenges.
1. Funding and competitive risks
Catalyst Investors favors revenue-generating robotics operators over robot-model developers, warning that assumptions about winner-take-all investment lack proven competitive barriers. Hardware-agnostic robot-model developers attracted roughly $1 billion per company, about 13 times the approximately $75 million raised by operators. Catalyst says model developers face commoditization pressure, lack durable proprietary advantages and have yet to prove reliable deployment at scale.
2. Real-world data example
Elbit Systems bought Bluewhite in May for its autonomy technology and more than 100,000 hours of operating data, underscoring the value of real-world data.
