Fei-Fei Li’s World Labs Raises $1 Billion Series C — Spatial AI Becomes a Funded Frontier

World Labs — the spatial-AI startup founded by Stanford professor Fei-Fei Li, the “godmother of AI” — has closed a $1 billion Series C, formally elevating spatial intelligence into a separately-funded AI frontier. The round follows the company’s December 2024 $230M raise and its recent demos turning still images into navigable 3D worlds.

The Round

$1 billion Series C
Builds on the December 2024 $230M raise
Implied total raised: ~$1.4B+
Among the largest single-year fundraises in AI startups in 2026
Investor base broadened from the seed/Series-B cohort

What World Labs Does

Spatial intelligence AI — understanding the 3D physical world from 2D inputs
Recent demos: turning a single still image into a navigable 3D world
Foundational tech for embodied agents, robotics, AR/VR, gaming, simulation
Distinct from the language-model frontier (OpenAI/Anthropic) and the diffusion-image frontier (Midjourney/Stability)

Why Spatial AI Matters

Robotics — humanoids + industrial robots need real-world spatial models
AR/VR — Apple Vision Pro, Meta Quest, Google XR need on-device 3D world models
Simulation — training environments for agentic workflows
Gaming — procedurally-generated 3D content
Mapping — autonomous-driving HD-map alternatives

The Fei-Fei Li Profile

Stanford professor; established ImageNet — the dataset that enabled the 2012+ deep-learning era
“Godmother of AI” — widely-acknowledged contributor to the modern AI revolution
Founded World Labs with three colleagues in 2024
Vocal proponent of “AI democratisation”

The Wider Funding Wave

Inertia: $450M Series A for fusion-laser energy systems
Recursive Intelligence: $300M Series A for AI-driven chip design
“The AI race is now about model cost, compute access, search distribution, and device control — not just flashy demos“
Money chasing a narrower class of startups with real distribution + infrastructure access
