OpenAI recently estimated its partnership with the AI coding startup Cursor would generate more than $1 billion in annual revenue, according to WIRED. Despite this lucrative projection, OpenAI decided to terminate the collaboration after Elon Musk’s SpaceX acquired Cursor, highlighting the complex and personal stakes in the AI industry’s rivalries.
This decision by OpenAI reveals a willingness to forgo substantial income to avoid any association with a company controlled by Musk, who co-founded OpenAI before a contentious departure. The move highlights the intense rivalries that often overshadow typical business considerations, even when billions of dollars are on the table.
Cursor’s Rapid Ascent and Strategic Value
Cursor launched in August 2026, specifically targeting developers frustrated with existing platforms like GitHub. The startup positioned itself as a rival hosting platform, aiming to provide a more tailored experience for AI-assisted coding. Its rapid growth and reported engagement must have been significant for OpenAI to project such a high annual revenue from their collaboration in just a few months.
The company also announced plans to open its first India office by the end of 2026, a strategic move indicating its global ambitions and intent to tap into India’s vast developer talent pool. This expansion plan, revealed in December 2026, suggests Cursor was already on a fast track for growth and market penetration before the SpaceX acquisition and subsequent OpenAI split.
For SpaceX, acquiring Cursor means bringing a promising AI coding tool in-house, potentially to streamline its own vast software development needs for rockets, satellites, and other advanced projects. The acquisition also positions SpaceX, and by extension Elon Musk, as a direct player in the AI development tools sector, a field where OpenAI has a strong presence with its own developer offerings.
The Shadow of Elon Musk
Elon Musk co-founded OpenAI in 2015 but left its board in 2018. Since then, his relationship with the company has been marked by public criticism and the founding of his own AI venture, xAI. OpenAI’s choice to sever ties with a billion-dollar revenue stream suggests a clear boundary regarding any indirect association with Musk’s business interests. This is not simply a matter of competitive overlap; it points to a deep-seated desire by OpenAI to maintain independence from Musk’s influence, even at a high financial cost.
The timing of these events is crucial. Cursor launched in August 2026. By late 2026, it was already planning international expansion. Then, within what appears to be a very short span, it became a billion-dollar revenue generator for OpenAI and was acquired by SpaceX. This sequence demonstrates the rapid pace of consolidation and strategic maneuvering in the AI industry, where promising startups are quickly identified, valued, and sometimes become pawns in larger corporate and personal rivalries.
OpenAI’s decision to walk away from a projected $1 billion annual revenue from Cursor is a stark measure, revealing the company’s prioritization of strategic alignment and autonomy over immediate financial gain. It also highlights the premium placed on avoiding conflicts of interest with key figures like Elon Musk, whose movements in the AI space are closely watched.
Cursor’s journey, from a startup addressing developer frustrations to a valuable acquisition target caught between AI giants, reflects the volatile nature of the current market. The company, which aimed to open its first India office by the end of 2026, now finds its future intertwined with SpaceX and outside of OpenAI’s direct influence, despite its early success.
