KEY HIGHLIGHTS

Anthropic accounted for 34.5% of SpaceX’s third-quarter revenue, making it the company’s largest customer.
Anthropic’s contract with SpaceX could involve spending up to $120.5B on computing through 2029, with monthly commitments of about $3.1B starting in December.
Anthropic retains the option to cancel the contract after early 2027 with 90 days’ notice.
SpaceX’s AI unit, Super Intelligence, turned a profit for the first time last quarter.
Google is another major customer, paying SpaceX approximately $920M monthly for computing power.

Anthropic’s contract and revenue impact

Anthropic has become SpaceX’s largest customer, contributing 34.5% of the company’s third-quarter revenue, according to reports. This surpasses revenue from the US government, previously SpaceX’s biggest client.

The contract between Anthropic and SpaceX could involve spending up to $120.5 billion on AI computing through 2029. Starting in December, Anthropic is expected to spend approximately $3.1 billion monthly on SpaceX’s infrastructure. However, the agreement includes a cancellation clause allowing Anthropic to exit after early 2027 with 90 days’ notice.

Anthropic is reportedly renting computing power at SpaceX’s data centers in Memphis, Tennessee, and other undisclosed locations.

SpaceX’s AI and financial growth

SpaceX’s AI division, Super Intelligence, turned a profit for the first time last quarter. The company’s overall revenue rose by 161% during the same period, reflecting its expansion into AI and cloud computing markets.

Google is another major customer, paying SpaceX about $920 million monthly for computing power. This highlights SpaceX’s increasing role in providing high-scale infrastructure for AI and cloud services.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

SpaceX’s pivot into AI infrastructure is now impossible to ignore. The $120.5 billion commitment from Anthropic—even with an exit option—validates SpaceX’s hardware as a viable alternative to incumbents like Nvidia, AWS, or Oracle for frontier AI workloads. For founders in AI, this is a signal to evaluate whether specialized hardware providers can offer cost or performance advantages over generic cloud offerings. The cancellation clause also underscores the risk of long-term commitments in a sector where hardware costs and capabilities change rapidly. Startups with smaller budgets may struggle to secure similar deals, reinforcing the advantage held by well-funded players like Anthropic.

Key takeaways

The contract signals SpaceX’s growing role in AI infrastructure, positioning it as a competitor to traditional cloud providers like AWS, Google Cloud, and Oracle.
Anthropic’s reliance on SpaceX for AI computing highlights the scale of infrastructure required for frontier AI models, which could pressure other AI startups to seek similar partnerships or hardware investments.
The cancellation clause after early 2027 suggests Anthropic is hedging against rapid shifts in AI hardware costs or performance, a risk other large-scale AI customers may also consider.
