Elon Musk transforms into a computing arms dealer! SpaceX signs a $6.3 billion deal with Reflection to lease Nvidia GB300 to support open-source AI

SpaceX has converted its massive computing power infrastructure into a commercial powerhouse, signing a compute leasing contract worth up to $6.3 billion with the open-source AI startup Reflection AI. Reflection will directly use top-tier Nvidia GB300 chips from the Colossus 2 data center to drive the development of “American open intelligence.” This move marks SpaceX’s official entry into the cloud computing power provider battlefield, opening up a brand-new revenue engine.

• Valued at $6.3 billion! Direct access to Nvidia GB300 top-tier computing power
• From in-house use to external leasing, SpaceX transforms into a cloud computing powerhouse
• Countering closed monopolies, open-source AI becomes a national-level strategy

The global AI computing power arms race has received a shock. According to CNBC’s latest report on June 22, 2026, SpaceX, led by Elon Musk, has turned its massive data center resources into a cash cow and has officially signed a large-scale computing agreement with the open-source AI startup Reflection AI, which has recently been valued at $25 billion. This deal not only establishes SpaceX’s ambition to become an AI infrastructure supplier, but also highlights the core position of top-tier compute resources in today’s technology strategy.

Valued at $6.3 billion! Direct access to Nvidia GB300 top-tier computing power

According to contract documents obtained by CNBC, Reflection will be able to immediately access Nvidia’s top-tier GB300 chips located in the Colossus 2 data center, specifically for training and running advanced AI models. The contract stipulates that, starting July 1, 2026, Reflection will pay SpaceX up to $150 million per month; if the agreement is carried out successfully through the end of 2029, the total transaction value will reach $6.3 billion.

To maintain commercial flexibility, the agreement also includes a termination clause: after the first three months of execution, both parties may terminate the contract with 90 days’ advance notice.

From in-house use to external leasing, SpaceX transforms into a cloud computing powerhouse

Looking back at SpaceX’s original purpose for building its super data center, Colossus (located in Memphis, Tennessee), it was initially developed to fully support the Grok chatbot built by its xAI. However, with the expansion of computing scale, SpaceX decided to sell excess capacity of Colossus and Colossus 2 (together totaling about 1 gigawatt) to the outside world, directly competing with traditional cloud providers.

In a market environment where top Nvidia chips are in severe short supply, compute power has become an extremely valuable strategic resource. Recently, SpaceX has signed compute contracts with major players such as Anthropic and Google, as well as the startup Cursor (rumor has it that SpaceX is in the process of acquiring Cursor). For SpaceX, which has just completed a record-breaking IPO, this undoubtedly proves to investors that, beyond rocket launches and Starlink satellite communications, AI infrastructure has become the company’s strongest new growth engine.

Countering closed monopolies, open-source AI becomes a national-level strategy

On the other hand, Reflection AI, which is splashing out large sums to lease compute power, is a startup that sticks to an “open-source” approach. Unlike companies such as OpenAI and Anthropic that adopt closed-model strategies, Reflection emphasizes that enterprises and governments should have the ability to inspect and customize the underlying models themselves. The recent controversial incident in which Anthropic abruptly cut off access to Fable and Mythos has further deepened outside concerns about over-reliance on closed systems.

A Reflection spokesperson said, “Recent events have highlighted the absolute importance of open source to the AI ecosystem. Countries and companies are gradually realizing that fully relying on closed models will come with enormous risks and costs.” With the powerful compute power provided by SpaceX, Reflection will accelerate the development of “American open intelligence.” At present, the company has successfully entered the national-level supply chain and is collaborating in depth with the U.S. Department of Energy’s Genesis Mission and the Pentagon’s military AI programs.
