📊 Full opportunity report: SpaceX Owns Every Layer of AI Now. The Model Is Still the Weak Link. on ThorstenMeyerAI.com — validation score, market gap, and execution plan.
TL;DR
SpaceX has purchased Cursor for $60 billion, gaining control over every layer of its AI stack, from hardware to applications. Despite this, the AI model itself remains a weak point, highlighting ongoing challenges in AI development.
SpaceX has finalized its $60 billion all-stock acquisition of Cursor, a profitable AI coding company, effectively owning every layer of its AI technology stack. This move places SpaceX in a unique position as the closest Western entity to a fully integrated AI conglomerate, controlling hardware, data centers, research, and applications. However, the core AI model remains a weak link, underscoring persistent challenges in AI performance.
On June 16, SpaceX announced it had exercised its option to acquire Cursor, a leading AI coding application, for $60 billion. The deal consolidates SpaceX’s control over the entire AI infrastructure, including its hardware, supercomputers, research labs, and applications. Founded in 2022, Cursor quickly became a profitable business, generating approximately $4 billion annually by June 2026, primarily through its AI coding tool, which is used by major tech companies and rivals.
By acquiring Cursor, SpaceX gains not only a profitable product but also a development team and a distribution channel, integrating these with its own compute resources, including the Colossus supercomputers in Memphis. The company owns the silicon, the power generation infrastructure, and the research teams behind the models, creating a vertically integrated AI ecosystem unmatched in the industry. The deal is expected to close in the third quarter of 2026, after which Cursor will become a wholly owned subsidiary.
Despite this comprehensive control, the core AI model—Grok—has shown performance limitations. Learn more about the challenges in AI models. Internal reports reveal that the model’s training utilizes only about 11% of the available FLOPs, far below the 35–45% efficiency typical of production-grade AI models. This inefficiency has led SpaceX to lease out its surplus compute capacity to rivals like Anthropic and Google, turning the Colossus supercomputers into lucrative rental properties. Musk has publicly stated that he reserves the right to reclaim this compute if the AI developed by rivals poses a threat to humanity.
SpaceX owns every layer
of AI now
The $60B Cursor buy completes the stack: power, compute, research, model, app, distribution. But owning every layer isn’t winning every layer — and the model is the weak one.

You can buy a coding app and a model team. You can’t buy the research lead that makes your foundation model the one everyone else builds on — which is why Anthropic pays Musk $1.25B/month, not the other way around. Owning every layer bought SpaceX the right to attempt the hard thing. It hasn’t done it yet.
Implications of SpaceX’s Complete AI Infrastructure Ownership
This acquisition positions SpaceX as a dominant force in AI infrastructure, controlling hardware, data centers, research, and application layers. Such vertical integration could reshape competitive dynamics, potentially giving SpaceX a strategic advantage in AI development and deployment. However, the persistent weakness of the core AI model highlights ongoing technical challenges that could limit the effectiveness of this control. The move also signals increased consolidation in the AI industry, with a few companies owning critical infrastructure and applications, raising questions about competition and innovation.

Background on SpaceX’s AI and Compute Expansion
Over recent years, SpaceX has built a formidable AI ecosystem, including the Colossus supercomputers capable of training massive models at unprecedented speeds. The initial buildout of Colossus 1 cost around $4 billion, with the expanded infrastructure reaching approximately 555,000 GPUs and a capacity of nearly 2 gigawatts. The company has integrated its AI research division, xAI, into its broader operations, with models like Grok and applications like Cursor generating significant revenue.
Prior to the acquisition, SpaceX was already a major player in AI compute, leasing out surplus capacity to competitors such as Anthropic and Google. The company’s strategy has involved owning silicon, power generation, and research, creating a tightly controlled ecosystem. The recent deal to acquire Cursor completes this vertical integration, making SpaceX arguably the most comprehensive AI infrastructure owner outside of China.

Unresolved Challenges in AI Model Performance
While SpaceX now controls the entire AI stack, the core model, Grok, exhibits low utilization rates and efficiency issues. It is unclear whether ongoing technical improvements will resolve these performance limitations or if they will persist, impacting the overall competitiveness of SpaceX’s AI offerings. Additionally, the strategic implications of leasing surplus compute to rivals and Musk’s safety reservations remain subject to further developments.

Next Steps in SpaceX’s AI Strategy
In the coming months, SpaceX is expected to finalize the Cursor acquisition, integrate the company fully into its ecosystem, and potentially address the model’s performance issues through further research and development. The company may also expand its compute leasing arrangements or reassert control over its AI infrastructure if technical or safety concerns escalate. Monitoring how SpaceX balances infrastructure dominance with model performance will be critical for industry watchers.
