Anthropic has agreed to spend $517 billion on computing power over the eleven months through August, according to The Information, a figure that dwarfs the $180 billion in commitments the company had previously disclosed and arrives even as its chief executive calls for a slowdown in frontier AI development.
The spending dwarfs prior guidance
The new total represents nearly three times the capital the lab had acknowledged committing to infrastructure. The Information’s reporting covers agreements signed through the end of August, a period that coincides with Anthropic’s most aggressive build-out yet. The scale suggests the company is locking in capacity years ahead of when models would actually consume it, a bet that demand for training and inference will keep outpacing supply.
Nvidia and AMD split the GPU pie
Nvidia remains the default for model training, with most foundational code written on its CUDA platform, and the company has extended its reach into inference through its acquisition of Groq. Chief executive Jensen Huang has forecast AI infrastructure spending of $3 trillion to $4 trillion by 2030, and Nvidia may anchor Anthropic’s eventual initial public offering with up to $10 billion. Advanced Micro Devices, meanwhile, secured a commitment to deploy up to two gigawatts of its Helios rack-scale systems starting in 2027, backed by a $5 billion investment in the lab. The deal follows similar inference agreements AMD struck with OpenAI and Meta Platforms.
TPUs become a Broadcom and Alphabet windfall
Anthropic is on track to become Broadcom’s largest customer as it rolls out Tensor Processing Units co-designed with Alphabet. Broadcom will capture the bulk of revenue from chip delivery and networking services, while Alphabet collects a high-margin stream that flows largely to the bottom line. Broadcom has outlined a deployment schedule of one gigawatt of Ironwood TPUs this year, five gigawatts of TPU v8i in 2027, and another ten gigawatts in 2028.
Amazon’s dual role deepens
Amazon, an early backer that holds roughly a twenty percent stake, also serves as a primary cloud provider. The company brought a massive data center online last year to support the partnership, embedding itself on both the equity and infrastructure sides of Anthropic’s expansion.
