SpaceXAI and Cursor: An Alliance Disrupting OpenAI

⚡

Key Takeaways

1SpaceX has acquired Cursor, strengthening its position in enterprise AI with a stock transaction.

2OpenAI, with a declining market share of ChatGPT, is facing increased competition from Meta and other players.

3Cursor's expansion, with an ARR of $4 billion, supports SpaceXAI's ambitions in AI.

💡Why it matters — This acquisition could redefine the balance of power in the AI sector, putting pressure on OpenAI to innovate.

SpaceXAI and Cursor: A Strategic Acquisition

SpaceX has recently completed the acquisition of Cursor, a company specializing in artificial intelligence, by settling the deal entirely in stock. This acquisition provides SpaceXAI with a viable future in the enterprise AI sector. Meanwhile, the newsletter "Good Morning, AI Supremacy" continues to closely monitor developments at the intersection of BigTech and BigAI, as well as promising startups looking to carve out a place in this rapidly expanding market. Among the already well-established giants, Microsoft, which supports OpenAI, finds itself in a historically leading position. However, OpenAI is considering creating a "super-application" by combining ChatGPT and Codex, an ambitious project just months away from a potential IPO. This initiative comes as ChatGPT's market share, which was over 50% until January 2026, has dropped to 46.4% in May, under pressure from competitors like Gemini (27.7%) and Claude (10.3%). With the rise of Meta's AI application, the future of ChatGPT remains uncertain.

OpenAI Facing Fierce Competition

Meta's AI application is experiencing rapid growth, supported by deep integration into an ecosystem of 3.5 billion daily active users. This expansion is facilitated by the development of standalone mobile applications and the addition of innovative features like the "AI mode" on Facebook. In the enterprise AI sector, Cursor stands out with an annual recurring revenue (ARR) of $4 billion as of June, and a growing run rate of 7x year-over-year. This puts OpenAI under pressure in both the B2C and B2B markets. The merger of ChatGPT with Codex represents a major challenge for OpenAI, and its success or failure could determine the company's future in an increasingly competitive market.

Cursor: An Asset for SpaceXAI

Cursor, with its rapidly growing revenue and expertise in AI agents, is an ideal partner for SpaceXAI, which seeks to expand its customer base in the enterprise AI sector. Although ChatGPT has reached one billion monthly active users, its market share is rapidly declining. The latest report on the state of AI in mid-2026 highlights several trends: ChatGPT's first-mover advantage is fading, consumer and business preferences are evolving, and users are increasingly willing to switch assistants. ChatGPT faces competition from Google with Gemini, Claude, SpaceXAI, Meta AI, as well as other well-funded companies like DeepSeek, Alibaba Qwen, Moonshot AI, Z.AI, and ByteDance.

The Impact of SpaceX's Acquisition of Cursor

SpaceX plans to finalize the merger with Cursor during the third quarter of this year. They are already collaborating quickly on new coding models, providing a new impetus to what was previously xAI, an entity struggling to generate revenue. SpaceXAI has jointly formed a model with Cursor, which will soon be launched in Cursor and Grok Build. This collaboration completely changes the landscape and puts even more pressure on OpenAI, given the soaring success of SpaceX's IPO. The rise of SpaceXAI and Meta AI through their AI application means that OpenAI is very likely to continue facing difficulties. Cursor, a startup spun out of MIT, represents a remarkable success in the history of technology.

Learning to Use Codex

For those looking to leverage Codex as an AI tool, the OpenAI Academy (unaffiliated) offers various workshops and live sessions. OpenAI has invested heavily in marketing and education to promote Codex, which could become an essential versatile tool. For OpenAI to achieve profitability, Codex must establish itself as a key player.

ChatGPT's market share is rapidly declining, while consumer and business preferences for AI are evolving quickly, with more options becoming available. The impact of Google Gemini and Claude continues to grow.

Recent Developments in Codex

Codex, initially designed as a tool for developers, is undergoing a transformation. OpenAI is expanding its scope to make it a versatile agent for various knowledge tasks. Once limited to automating coding tasks, Codex is now integrated into tools like Gmail, Calendar, PowerPoint, and even a planned merger with ChatGPT. OpenAI aims to make Codex a central tool for accomplishing a variety of tasks, beyond just software development.
