Anthropic has abandoned its pursuit of Decart AI in a deal valued at roughly $6 billion, Bloomberg reported. The Claude maker completed due diligence on the chip efficiency startup before walking away, though both companies may still explore other forms of collaboration as Anthropic prepares for what could be the largest IPO in history.

Anthropic Abandons $6bn Decart AI Acquisition

Anthropic has decided against acquiring Decart AI after completing due diligence, Bloomberg reported on September 8, citing people familiar with the matter who asked not to be identified

. The deal, valued at roughly $6 billion, would have been Anthropic's largest acquisition to date and represented a significant premium over Decart's nearly $4 billion valuation from its May funding round

. Representatives for both companies declined to comment to Bloomberg, though sources indicated the two may still find other ways to work together

Chip Efficiency Was the Target, Not World Models

What Anthropic wanted from Decart AI has been widely misread since the talks first surfaced. While Decart is publicly known for world models like its Lucy live-video editing model and Oasis simulation platform designed for autonomous driving and e-commerce applications

, the acquisition rationale centered on chip efficiency technology

1

. Decart's optimization stack is designed to make chips work harder across both AI training and inference workloads, with the company's website promising to "squeeze every ounce of performance from every chip"

1

. The idea was to let Anthropic's existing compute infrastructure absorb more demand and reduce computing costs without proportional expansion of resources

IPO Timing and Premium Pricing Complicate Deal

The collapsed deal comes as Anthropic prepares for a public listing expected to delay marketing its IPO prospectus to mid-October

2

. Investors hope the highly anticipated offering will make the largest debut in history, raising $75 billion or more at a $2 trillion valuation

2

. The company has signed some $517 billion in compute capacity leases over just the past 11 months, amounting to roughly 14.8GW of capacity

2

. Buying a way to make existing infrastructure go further is rational in that position, but paying a substantial premium weeks before a listing is harder to defend to incoming shareholders

1

. The $6 billion purchase would have represented roughly a 50% markup just four months after Decart's May valuation

Decart's Dual Business and Investor Backing

Decart raised $300 million in May in a round led by Radical Ventures, with NVIDIA, Adobe Ventures, Valor Equity Partners and Atreides Management joining, alongside earlier backers Sequoia Capital, Benchmark and Zeev Ventures

1

. Founded in 2023 by brothers Dean and Orian Leitersdorf with Moshe Shalev, former Israeli Defence Forces intelligence unit soldiers, Decart runs two businesses that sit unusually far apart

2

. One is the chip optimization layer Anthropic was interested in, while the other focuses on world models trained on text and millions of hours of video to internalize how physical objects behave

1

. Its Lucy model takes live video of a person and generates high-resolution video of them wearing something they are not, tackling the virtual try-on problem that has challenged fashion e-commerce for a decade, with eBay serving as both investor and customer

What to Watch: Commercial Agreement Over Ownership

Neither party has disclosed which consideration ended the talks, and reporting does not establish whether Anthropic balked at the price or at something due diligence turned up

1

. A company preparing to list has every reason to want its cost base looking efficient and its acquisition history looking disciplined, and those two impulses pointed in opposite directions here

1

. The decision preserves financial flexibility while keeping attention on infrastructure expansion before Anthropic's potential IPO

5

. Whether the collaboration the two sides are said to be still considering means a commercial agreement for that chip efficiency stack, rather than ownership of it, is the thing to watch—it would be the cheaper version of the same idea, and it would not need explaining in a prospectus

1

. For Decart, the collapsed deal could push the startup toward fresh buyers, investors, or strategic partnerships following Anthropic's withdrawal
