World Labs Valuation: What Fei-Fei Li's Spatial Intelligence Startup Is Worth at $5B

World Labs is reportedly worth $5 billion as of February 2026 — a 5x markup in 17 months on a company with no disclosed revenue, a 3D-world generator that costs $20 to $95 a month, and a robotics team it just acquired with part of the round.

Fei-Fei Li, the Stanford computer scientist who built the ImageNet dataset that helped kick off the current era of deep learning and now co-directs Stanford's Human-Centered AI Institute, started World Labs in Palo Alto, California in April 2024 with three co-founders: Justin Johnson, Christoph Lassner, and Ben Mildenhall. Less than two years later, the company has raised about $1.23 billion, shipped one commercial product, and used a chunk of its newest round to buy a robotics-simulation startup. None of that has come with a disclosed dollar of revenue.

World Labs Valuation in 2026: How a $1B Company Became a Reported $5B Company

World Labs came out of stealth on September 13, 2024 with $230 million at a $1 billion post-money valuation. Seventeen months later, a $1 billion round closed at what multiple outlets reported as a roughly $5 billion mark — though the company itself has never confirmed the number in public. That gap between reported and confirmed is the story: this is a valuation built almost entirely on syndicate confidence, not on disclosed usage or revenue.

The reported number first surfaced on January 23, 2026, when Bloomberg reported World Labs was in talks to raise up to $500 million at a $5 billion valuation. Three and a half weeks later, on February 18, 2026, the company announced it had closed $1 billion instead — twice the size Bloomberg had floated — with $200 million of it coming from Autodesk, according to TechCrunch. World Labs declined to say whether the closing valuation matched the $5 billion figure Bloomberg had reported weeks earlier, which is why every outlet since has described the mark as “reportedly” or “roughly” $5 billion rather than citing a confirmed post-money number.

The Funding Timeline: Founding to a $1B Round in 22 Months

Two priced rounds, one acquisition, and two product launches — all inside 27 months. The pace accelerated sharply after Marble, World Labs' first commercial product, went public in November 2025; every major event since then has landed within a ten-week window.

Who Actually Invested, and What Autodesk Bought With $200 Million

The September 2024 seed was led by Andreessen Horowitz, NEA, and Radical Ventures, with individual backers including Marc Benioff, Jeff Dean, Geoffrey Hinton, Reid Hoffman, and Eric Schmidt, per Forbes. The February 2026 round shifted the investor mix toward corporates with a direct commercial stake in 3D AI: Autodesk put in $200 million — the largest startup investment in the design-software company's history, according to Autodesk's own announcement — and secured an advisory role tying its CAD and 3D-content tools to World Labs' models. AMD, Nvidia, Fidelity Management & Research, Emerson Collective, and Sea rounded out the round.

Nvidia and AMD backing the same round is unusual — the two chipmakers are direct competitors everywhere else in AI infrastructure. One read on this: both companies want a stake in whichever lab ends up defining how 3D world models get trained, since that workload could eventually rival language-model training as a source of GPU demand. Neither company has said that publicly; it is inference from the cap table, not a stated strategy.

Autodesk's stake is easier to explain. The Manchester, New Hampshire-based maker of AutoCAD, Revit, and Maya sells software that professionals use to build 3D content by hand, and a model that can generate spatially accurate 3D environments from a photo or a sentence is either a productivity tool for that workflow or a threat to it. Putting $200 million behind World Labs, plus an advisory seat at the research level, is a bet on the first outcome — and a way to make sure Autodesk's file formats and workflows are built into whatever World Labs ships next, rather than discovering later that a rival design tool got there first.

Marble: The Only Product Behind the $5B Number

Marble, World Labs' flagship product, turns text, images, or video into persistent, downloadable 3D environments — a different approach from rivals that generate worlds on the fly as a user moves through them. It launched publicly on November 12, 2025 with a hybrid editor that lets users block out spatial structure before the model fills in visual detail, plus a “Chisel” editing tool added afterward.

Pricing runs on a credit-based subscription: a free tier with four generations, Standard at $20 a month for 12 generations plus multi-image input, Pro at $35 a month for 25 generations with commercial usage rights, and Max at $95 a month for 75 generations. A pay-per-use World API for developers followed on January 21, 2026. World Labs has not disclosed how many people pay for any tier, or what the products generate in revenue — the $5 billion mark is priced on team, technology, and investor conviction, not on a P&L anyone outside the company has seen.

The July 21, 2026 acquisition of SceniX points to where World Labs thinks the bigger opportunity sits. SceniX built simulation environments where robots practice skills before running on physical hardware, and its co-founders, Yunzhu Li — a Columbia University assistant professor with a PhD from MIT's Computer Science and Artificial Intelligence Laboratory — and Changxi Zheng, joined World Labs as part of the deal, per Tech Startups. Terms were not disclosed, and Dealroom described the deal as shaped like an acqui-hire of a small academic team rather than a purchase of an established commercial product. Read together with the Autodesk tie-up, the sequence looks like a company hedging between two markets — creative and design tools sold to people, and simulation infrastructure sold to robotics companies — rather than committing to either.

How the $5B Mark Compares to Runway, Decart, and Odyssey

World Labs is not the highest-valued company chasing world models, and it is not the one with the clearest revenue story either. Runway raised $315 million at a $5.3 billion valuation on February 10, 2026 — eight days before World Labs' own round closed — and had already crossed roughly $300 million in annualized recurring revenue on more than $860 million raised since founding. Decart, an Israeli lab building real-time world models, raised $300 million at a nearly $4 billion valuation in May 2026 with Nvidia again among the backers. Odyssey, building interactive world-model APIs, raised $310 million at a $1.45 billion valuation in June 2026.

World Labs has raised more total capital than any of its three closest peers, but its reported valuation is the second-lowest of the four — and the only one of the four with no disclosed revenue figure at all.

None of those four are the only ones building this technology — they are simply the only ones priced as standalone startups. Google DeepMind shipped Genie 3, a world model that generates interactive 3D environments at 24 frames per second and holds them consistent for several minutes, to the public on January 29, 2026, following an August 2025 research preview. Nvidia's Cosmos platform, aimed at generating synthetic training data for robots and self-driving systems, had logged roughly 2 million downloads by mid-2026. Neither has a standalone valuation because both sit inside a public company's balance sheet — but both compete directly for the same research talent and the same enterprise customers World Labs is chasing with Marble and the SceniX team.

What the headline misses

“$5 billion for a company with no revenue” sounds like the story, but it undersells how contested the entire world-model category is. VCs poured roughly $3 billion into world-model startups in the first half of 2026 alone, according to Forbes — meaning World Labs is one of four or five companies all being priced on the same bet that spatial and physical reasoning, not just language, is the next frontier. A $5 billion mark on a two-year-old company looks aggressive in isolation and roughly in line with the category once you set it next to Runway and Decart.

The real risk sits elsewhere: World Labs is now straddling three different businesses — a consumer-facing 3D generation tool, an enterprise design partnership with Autodesk, and a robotics-simulation unit bought through SceniX — without public evidence that any one of them is working commercially yet. Runway has an ARR figure to point to. World Labs, as of August 29, 2026, does not, and a company spreading a still-unproven product across three go-to-markets at once is a harder story to underwrite than one doing a single thing well.

What Would Reprice World Labs From Here

Three things would move the number next. The first is a disclosed revenue figure — World Labs is the only one of its four closest peers that has never put out an ARR estimate, and even a modest confirmed number would give the next round something other than team and demos to price against. The second is how the SceniX integration plays out: if World Labs starts landing named robotics customers for simulation, that reframes the company from a creative tool to infrastructure, which tends to command a different multiple entirely. The third is Autodesk's own read on the partnership — a design-software incumbent putting $200 million behind a two-year-old startup is a strong signal, but the value of that bet only shows up once Autodesk actually ships something built on World Labs' models into its own products.

Watch for a follow-on round or a priced secondary market quote as the earliest signal — companies at this stage in the world-model race have been getting remarked every few months, and World Labs has gone without a confirmed new number since the February close.

The Bottom Line

World Labs enters late August 2026 with $1.23 billion raised, a reported $5 billion valuation the company has never confirmed, a $20-to-$95-a-month product with no disclosed revenue, and a new robotics-simulation team bought through the SceniX acquisition. The mark is not an outlier against Runway and Decart, but World Labs is the only one of the three still without a public revenue number to defend it — which makes the next disclosed figure, whatever it is, the thing likely to move the price more than any new funding round.
