The company behind the Claude chatbot had been in early talks to buy Decart since at least August. It completed due diligence on the startup before deciding not to move forward.
Representatives for both companies declined to comment.
What Decart Does
Decart, which is backed by chipmaker Nvidia, builds software that helps AI systems run more efficiently across different types of chips. Its technology can reduce the cost of training and operating AI models.
For Anthropic, the acquisition could have helped lower infrastructure costs and handle growing demand for Claude. But despite walking away from the deal, the two companies may still collaborate in other ways.
Anthropic Eyes IPO
Anthropic is ramping up spending on computing power as it builds new products and prepares for a public listing. The company is expected to begin marketing its IPO as early as mid-October, with a potential listing before the U.S. midterm elections in November.
People familiar with the plans say Anthropic could seek to raise as much as SpaceX or more in its offering. That would make it one of the largest technology IPOs in recent years.
The company rarely makes large acquisitions. Its recent deal activity had been seen as part of a broader push to expand AI infrastructure ahead of going public.
Dropping the Decart deal does not appear to signal a slowdown in that spending. Anthropic has said it continues to invest heavily in computing capacity and AI model development.
Higher infrastructure spending could pressure near-term cash flow, but the company says the investment is aimed at supporting new and more advanced AI products.
The failed acquisition was notable given its size. For Anthropic, a $6 billion deal would have been its largest ever.
Whether the company pursues similar deals before its IPO remains to be seen. But the spending on infrastructure is expected to continue regardless.
Decart’s chip efficiency software remains relevant in an industry where AI compute costs are rising. Other companies may look to acquire or partner with the startup.
Anthropic’s IPO timeline is still on track, with mid-October seen as a potential start date for marketing the offering to investors.
