Cursor "sells itself" to Space X due to heavy pressure from Claude and computing power

AI programming assistant Cursor chooses to join SpaceX, driven by a multifaceted crisis including stalled fundraising, fierce competition, and high computational costs.

According to The Information, just weeks before SpaceX announced its intention to acquire Cursor at a potential $60 billion valuation, the high-profile AI programming startup was seeking billions of dollars in funding but was repeatedly rejected. Multiple leading investment institutions, usually capable of making large investments, declined Cursor, citing concerns about its competitive prospects due to the rapid rise of Claude Code under Anthropic. A fund manager who recently met with Cursor executives bluntly stated: “Investor fear of Anthropic is very pronounced right now.”

This acquisition is significant for Cursor: if the deal goes through, Cursor will gain access to SpaceX’s massive server resources; if SpaceX eventually backs out, Cursor will receive a $10 billion breakup fee. This deal not only resolves Cursor’s immediate computational power issues but also provides a strategic path out of its reliance on Anthropic and OpenAI models.

Fundraising Obstacles and the Shadow of Anthropic

Cursor’s fundraising dilemma reflects the delicate landscape of the current AI investment market.

According to sources, major late-stage technology investment institutions such as Iconiq have previously injected billions into OpenAI and Anthropic. Faced with Cursor’s anticipated $50 billion valuation, these groups are unwilling to further fund a competitor and are doubtful whether Cursor can consistently compete with better-funded rivals.

Financial data further heightens investor concerns. According to two people directly familiar with its finances, Cursor’s gross margin was negative 23% in the quarter ending January this year—a rare figure for a startup with such a large revenue base. However, another source indicated that the company’s gross margin has since turned positive.

Nevertheless, some investors remain attracted by Cursor’s growth momentum and its strong reputation among developers. Sources note that Cursor’s annualized revenue reached $2.7 billion last month, increasing roughly 14 times year-on-year; some investors expect annualized revenue could surpass $7 billion by year-end. Ultimately, Cursor raised $2 billion in new funds from institutions including Nvidia, Andreessen Horowitz, Thrive Capital, and Battery Ventures, with Nvidia taking the largest share. However, this funding round was halted immediately after the SpaceX acquisition announcement.

The Relentless Financial Pressure of Compute Costs

Compute costs are another sword hanging over Cursor’s head.

Cursor’s programming tools and intelligent agent products heavily rely on models from Anthropic and OpenAI, meaning the company pays high fees to its biggest competitors, which directly erodes profit margins. Accordingly, Cursor has begun developing its own models based on open-source alternatives to reduce dependence on external models and improve gross margins.

But in-house development also requires massive investment. Sources indicate that even after closing the aforementioned funding round, Cursor’s management still anticipates needing to raise billions more by year-end, specifically to support AI compute power. This ongoing funding gap makes strategic acquisitions a more attractive option.

SpaceX’s Plan: Boost Revenue and Enter the Enterprise Market

For SpaceX, acquiring Cursor likewise has clear strategic logic.

According to an earlier report by The Information, SpaceX’s xAI division had capital expenditures of $12.7 billion last year and carries significant debt, but the division’s annual revenue was just $3.2 billion, with most coming from the social media platform X. In comparison, Cursor achieved roughly $770 million in revenue in the last fiscal year ending January 2024, nearly 24 times the prior year’s $32 million—a figure equivalent to nearly one-quarter of xAI’s annual revenue.

Joining forces with Cursor would give xAI a substantial enterprise-focused AI application business—an area where xAI’s Grok product has yet to make significant inroads. In addition, both parties plan to jointly develop proprietary programming models to help Cursor gradually reduce its dependence on Anthropic and OpenAI.

However, this transaction would also weigh on SpaceX’s financial performance: Cursor lost nearly $900 million in the last fiscal year. If the acquisition is completed, early investors like Andreessen Horowitz and Thrive Capital would reap substantial returns—Cursor’s valuation reached $30 billion at the end of last year, up from less than $3 billion at the beginning of the year. SpaceX is now actively engaged in a series of investor roadshows to prepare for an IPO expected in June this year, with a potential valuation of $1.5 trillion.
