A seismic shift is brewing in the AI industry as SpaceX prepares to finalize its $60 billion acquisition of the coding startup Cursor. The deal, announced last month, promises to supercharge Cursor with SpaceX’s immense computing resources. But a critical question now hangs over the tech world: Can Cursor remain an open platform for rival AI models from OpenAI and Anthropic once Elon Musk’s rocket company takes the helm?
Cursor has long built its success on being model-agnostic. While the startup recently began training its own proprietary models, its core product allows developers to choose from a menu of third-party offerings—including those from Anthropic and OpenAI—to power their coding tasks. This strategy has made Cursor a vital distribution channel for these AI labs, which feature the startup prominently in their marketing materials. However, the SpaceX acquisition, expected to close later this year, directly pits Cursor against these same labs. Both OpenAI’s Codex and Anthropic’s Claude Code have evolved into direct competitors to Cursor’s own coding assistant.
Insiders close to Cursor say the company hopes to maintain its platform model post-acquisition, continuing to serve Anthropic and OpenAI’s technologies alongside its own. But industry analysts are skeptical. “The tension is unavoidable,” says Eno Reyes, CTO of rival coding startup Factory. “When a platform is owned by a competing AI lab, the question isn’t just about technical access—it’s about trust and strategic alignment. The decision isn’t black and white, but it’s definitely murky.” Reyes notes that neither Anthropic nor OpenAI has publicly committed to continuing their partnership with a SpaceX-owned Cursor.
The stakes are enormous. For SpaceX, owning Cursor gives Musk a direct foothold in the developer tools market, a move that could accelerate his broader AI ambitions. For OpenAI and Anthropic, losing access to Cursor’s millions of users would be a significant blow to their market reach. Meanwhile, Cursor itself faces a delicate balancing act: If it prioritizes its own models or restricts third-party access, it risks alienating the very developer community that made it a unicorn. As the deal awaits regulatory approval, all parties remain tight-lipped. Cursor declined to comment; SpaceX, OpenAI, and Anthropic did not respond to requests. The outcome will likely define the next phase of the AI platform wars.
