July 5, 2026 – When SpaceX announced its blockbuster $60 billion acquisition of AI coding startup Cursor last month, industry watchers hailed it as a strategic win for both sides. Cursor gains access to SpaceX’s massive computing infrastructure for model training, while Elon Musk’s empire absorbs one of the most widely used developer tools in the market. But a critical question is now roiling the AI sector: Will rival labs like OpenAI and Anthropic continue to let Cursor distribute their models after the deal closes later this year?
Cursor’s entire business model has relied on being a neutral platform. Developers choose from a menu of models—including OpenAI’s GPT series, Anthropic’s Claude, and Cursor’s own in-house offerings—to power their coding assistants. This approach allowed Cursor to offer the best or cheapest option at any given moment, and it made the startup one of the largest customers for both OpenAI and Anthropic. Those labs have also prominently featured Cursor in their marketing materials, highlighting the symbiotic relationship.
However, the SpaceX acquisition transforms Cursor from a neutral partner into a direct competitor. Both OpenAI and Anthropic now run their own coding tools—Codex and Claude Code, respectively—that compete head-to-head with Cursor’s product. With SpaceX, a company led by Musk—who has publicly sparred with OpenAI’s leadership and pursued his own AI ambitions—the stakes are far higher. Industry insiders are watching closely to see whether Anthropic and OpenAI will pull their models from Cursor’s platform once the deal is finalized.
“I don’t know if the decision is as black and white,” said Eno Reyes, cofounder and CTO of Factory, a smaller AI coding rival. “It’s actually super unclear to us.” Reyes noted that cutting off Cursor could hurt the labs’ own revenues and market reach, but leaving their models on a Musk-owned platform might be politically untenable. Cursor declined to comment for this story. Anthropic, OpenAI, and SpaceX did not respond to requests for comment.
The outcome will shape the broader AI landscape. If Cursor retains open access to third-party models, it could set a precedent for how AI tools operate under conglomerate ownership. If the labs pull out, it would force Cursor to rely entirely on its own models—potentially weakening its competitive edge. With the deal still pending regulatory approval, the clock is ticking for all parties to decide whether this frenemy relationship can survive the SpaceX era.
