❯ Nvidia’s physical AI business runs at about $10 billion a year as Chinese robot makers lean on it

two factsPer Raffaele Huang at the Wall Street Journal, industry insiders say Chinese robot makers currently rely on Nvidia’s silicon and software, and the same report puts Nvidia’s physical AI business at roughly $10 billion in annual revenue. Jensen Huang has previously described that as a $10 billion annualized run rate, and sees it reaching $100 billion within a decade.

the other side of export controlsThe fact sits in tension with the current control regime: the U.S. restricts China’s access to advanced AI chips, yet the dependency holds on the robotics line — Nvidia’s humanoid-focused Isaac GR00T models and simulation systems are already the default toolchain, and the company picked Unitree as a humanoid platform partner this year. Huang has publicly called China “formidable” in robotics. The software ecosystem matters more durably than the silicon here, because migrating simulation and training tools is extremely costly.

who gets caughtTen billion dollars looks small next to Nvidia’s $96.2 billion quarter, but it marks where the next battleground sits. Chinese robot makers’ supply-chain assumptions take the pressure first: if physical-AI silicon comes under controls, the alternative is not just a different chip but rebuilding the whole simulation and training toolchain. On the same day, Tesla is still climbing toward a consumer Optimus launch while SoftBank moves to buy 1X at $6 billion — the money in this field and the dependency in this field are accelerating at once.

▪ SIGNALOn the robotics line, what Nvidia actually sells is the simulation toolchain; the chip is just its carrier.
