📊 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 bought Cursor for $60 billion, gaining control of every AI layer except the model itself. While its infrastructure is extensive, the AI model continues to face performance challenges, highlighting ongoing issues.
SpaceX has completed its $60 billion all-stock acquisition of Cursor, a profitable AI coding application, consolidating control over every layer of the AI stack except the AI model itself. This move positions SpaceX as a significant player in AI infrastructure, but the weakness of the model remains a point of consideration.
On June 16, SpaceX announced it exercised its option to buy Cursor, a leading AI coding company, for $60 billion in all-stock. The deal, expected to close in the third quarter of 2026, makes Cursor a wholly owned subsidiary of SpaceX. Founded in 2022 by MIT graduates, Cursor had reached approximately $4 billion in annual revenue by June, primarily from AI coding tools that generate revenue reliably.
SpaceX’s acquisition encompasses not only Cursor’s profitable application but also its development team, distribution channels, and the AI models. The company now controls every layer of the AI stack: compute (via its Colossus supercomputers and ambitions for orbital data centers), power (built-in gas generation), research (through its xAI division), the model and application (Grok and Cursor), and distribution (via Tesla, X, and other platforms). This vertical integration is extensive.
However, despite owning the infrastructure and the application layer, the core AI model, which underpins these systems, continues to face performance issues. Recent reports indicate the model’s performance is below industry standards, with low utilization rates and challenges in parallelization, suggesting ongoing difficulties in training and deployment.
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 Full AI Stack Ownership for Market Power
Owning every layer of the AI stack provides SpaceX with comprehensive control over hardware, research, and applications. This level of integration could influence competitive dynamics, potentially affecting how rivals access or develop AI infrastructure. Nonetheless, the persistent performance issues of the AI model highlight that infrastructure control alone may not guarantee success in AI development, raising questions about the overall strategic advantage.

Background on SpaceX’s AI Infrastructure and Recent Developments
Prior to this acquisition, SpaceX had invested in developing its own AI compute infrastructure, notably the Colossus supercomputers in Memphis, which now operate with approximately 555,000 Nvidia GPUs. The company has also expressed interest in deploying AI satellites as orbital data centers, aiming to integrate AI processing into space infrastructure. Meanwhile, Cursor emerged as a profitable entity, specializing in AI coding tools, attracting interest from major tech companies like OpenAI and Microsoft, but choosing to remain independent.
The deal marks a step in SpaceX’s strategy of vertical integration, consolidating control over hardware, research, and applications, while the core model’s performance remains an area for potential improvement.
“We’re comfortable leasing our compute because the training has moved on, but we retain the option to reclaim it if necessary, including concerns about AI safety and performance.”
— Musk, SpaceX CEO

Unresolved Challenges in AI Model Performance
It remains uncertain how effectively SpaceX can enhance the performance and utilization of its AI models, particularly the core model that supports its systems. While infrastructure and applications are under control, the ongoing performance issues of the model could impact overall AI capabilities and competitive positioning. Details on specific efforts to improve the model are not yet publicly available, and progress remains to be seen.

Next Steps for Improving AI Model Capabilities
SpaceX is likely to focus on refining its AI models through further training, optimization, or development of new architectures. The company may also leverage its extensive compute resources and data to support these efforts. Monitoring the progress of these improvements will be important to assess whether the company can overcome current limitations and strengthen its AI offerings.
