Anthropic commits $15 billion annually to SpaceX's Colossus data centers through 2029

SpaceX and Anthropic’s $15 billion annual compute deal

According to The Verge, SpaceX’s IPO filing revealed that Anthropic committed to paying $1.25 billion per month through May 2029 for access to the Colossus I and Colossus II data centers in Memphis, Tennessee. The agreement totals $15 billion annually—a sum nearly equivalent to SpaceX’s total 2025 revenue of $18.7 billion. The deal was announced earlier in May 2026 but lacked financial specifics until the IPO disclosure.

Contract flexibility and capacity ramp-up

The compute supply agreement includes a mutual exit clause permitting either party to terminate within 90 days. The Verge reports that Anthropic’s monthly fees will be reduced during the capacity ramp-up this month and next, reflecting the phased buildout of the facilities. This flexibility is likely necessary given the fast-moving nature of the AI industry, particularly because Anthropic’s Claude model competes directly with SpaceX’s Grok offering.

SpaceX’s AI spending and financial trajectory

SpaceX has dramatically shifted spending toward AI infrastructure following its merger with Elon Musk’s xAI earlier in 2026. The company spent $12.7 billion in capital expenditures on AI in 2025—representing 61 percent of its total capital spend. In the first quarter of 2026 alone, SpaceX allocated $7.7 billion to AI compared to just $1 billion for its space division. Despite this investment, SpaceX’s AI division posted a $6.3 billion operating loss on $3.2 billion in revenue in 2025, and a $2.5 billion loss on $818 million in revenue in Q1 2026.

Anthropic’s revenue acceleration

Anthropic is on track toward its first quarterly operating profit, with sales revenue expected to reach at least $10.9 billion in the coming quarter, according to Reuters reporting cited by The Verge. This represents more than double the company’s $4.8 billion in revenue for the quarter ended in March 2026.

SpaceX’s broader compute-as-a-service strategy

Musk signaled on X that SpaceX intends to market Colossus capacity beyond Anthropic, stating that SpaceX stands ready to offer similar deals to other AI companies seeking large-scale compute access. The move reflects both the scarcity of GPU capacity and the company’s confidence in the Colossus infrastructure.

Why This Matters

The $15 billion annual commitment underscores the acute scarcity of training compute in the AI industry. With data center buildouts facing local opposition across the country, established AI companies are bidding aggressively for access to newly completed facilities. For Anthropic, securing three years of dedicated capacity signals confidence in revenue growth and model development timelines—critical for a company approaching profitability. For SpaceX, the Anthropic contract validates its pivot into compute-as-a-service and demonstrates willingness to monetize xAI’s infrastructure investments. The 90-day termination clause, however, reveals mutual hedging: in an industry where model architectures and competitive dynamics shift rapidly, neither party is willing to lock in multiyear commitments without escape routes. Other AI labs will likely evaluate similar deals as SpaceX opens its capacity to additional customers.
