Why SpaceX is Willing To Pay $60B for Cursor, and Even Lock-in a Whopping $10B Collaboration Fee

Everything was in line for Cursor, the San-Francisco based AI-code editor startup to raise its §$2 billion round. With a valuation of $60 billion, the round was oversubscribed- a dream come true for any company. It also had the biggest venture capital names in Silicon Valley poised to sign the cheque - Andreessen Horowitz was co-leading, Thrive Capital, Nvidia, and Battery Ventures were all committed. But then SpaceX intervened with an offer that seems  - impossible to refuse.

Simply put SpaceX is set to acquire - Anysphere (Cursor’s parent company) for $60 billion post the former’s June IPO later this year. In any case if the deal and acquisition doesn’t go through, SpaceX is also willing to pay a $10 billion fee for collaboration working - making it one of the largest termination fee bills in history. The reason for such a high shopping bill is purely competitive. 

Cursor hit $100 million in annualised revenue in January 2025, $500 million by June, $1 billion by November 2025, and $2 billion by February 2026 — the fastest-growing SaaS company on record. It projects a $6 billion run rate by end of year, with 67% Fortune 500 penetration. 

Cursor still uses and sells access to Claude and GPT models even as both Anthropic and OpenAI roll out their own competing coding tools — an awkward arrangement this SpaceX partnership may be designed to eventually escape.  The SpaceX Colossus cluster, equivalent to one million H100 GPUs, provides the training compute to build independent models without dependence on rivals. This cluster is equivalent to one million H100 GPUs and is touted as the largest in the world.

Access to this massive infrastructure is transformational for Cursor, allowing it to dramatically scale up the intelligence of its proprietary model, Composer, at a scale it could not afford independently, thereby restructuring its entire unit economics. The newest version of Cursor's proprietary model, Composer, was built on top of an open-source model from the Chinese startup Moonshot AI.

The acquisition is part of Elon Musk's accelerating push to transform SpaceX into an AI conglomerate. The deal provides a strong "valuation anchor," which is expected to help transition SpaceX’s IPO narrative from a commercial aerospace company to a "tech empire" encompassing computing, data, and AI, thereby boosting its long-term valuation multiples.

The agreement is also a strategic move to block major competitors, such as Microsoft, which had previously explored a potential acquisition of Cursor but ultimately decided not to proceed. SpaceX also seeks to combine "Cursor's leading product and distribution to expert software engineers" with its own massive computing power. The deal gives SpaceX access to a commercially successful AI coding product to help reel in rivals. 

While not explicitly mentioned in the search results, the original text states the logic is competitive. The deal is considered strategically vital for xAI - which merged with SpaceX in February - as Cursor’s developer-tool status has amassed a vast repository of data on programming processes crucial for enhancing AI model capabilities, which xAI’s social media data from X cannot provide.

Cursor's AI assistant has been a central tool in what the technology industry refers to as the ‘vibe coding ‘ era—a shorthand for AI-assisted development workflows that have rapidly transformed how software is built.

The formal acquisition is being delayed until after SpaceX's June IPO. The flotation is expected to value the combined group at a whopping  $1.75 trillion, which would be the largest in history.

However, the merger of xAI with SpaceX has complicated the financial picture. xAI reportedly lost $6.4 billion in 2025 (up from $1.56 billion in 2024), while Starlink (SpaceX's satellite internet business) posted an operating profit of $4.42 billion last year.

Over the past year, Elon Musk has merged parts of his business empire, including his social media platform X and xAI, into a single entity under SpaceX.

For every other company in the AI coding market, the announcement is a signal that the consolidation phase has begun. The next deals in this space may not be fundraises, but maybe acquisitions.
