SpaceX、Cursorを9兆円買収も『まだ完了』していない理由SpaceX is in advanced talks to acquire AI code editor Cursor at a reported…

SpaceX is reportedly in advanced negotiations to acquire Cursor, the AI-powered code editor, in a deal said to value the company at roughly 9 trillion yen, or about 60 billion US dollars. Despite the scale of the talks, the transaction has not yet formally closed, with regulatory review and unresolved contractual terms cited as the main obstacles. If completed, a purchase of this size would rank among the largest technology acquisitions on record and would mark an unusual expansion for a company primarily known for rockets and satellite internet rather than developer software.

Cursor is an AI code editor developed by the startup Anysphere. Built as a fork of Microsoft's open-source Visual Studio Code, it embeds large language models directly into the editing workflow, allowing developers to generate, refactor, explain, and debug code through natural-language prompts. The product has gained rapid traction among individual programmers and engineering teams, and its rise reflects a broader shift toward "AI-native" development environments where the assistant is central to the interface rather than an add-on. That momentum is the most plausible reason a valuation in the tens of billions of dollars is being discussed at all.

The reported reasons the deal has not closed are consistent with how large acquisitions typically proceed. Being in "advanced talks" is not the same as signing, and even a signed agreement usually depends on closing conditions being met. Regulatory review is often the longest of these. Transactions of this magnitude generally attract scrutiny from competition authorities, and reviewers examine whether combining the companies would reduce competition or give the acquirer undue leverage over a strategic market. Contractual hurdles can include due diligence findings, financing arrangements, warranties, employee retention terms, and the treatment of existing partnerships, any of which can delay or reshape a final agreement.

A further complication that appears relevant here is the question of underlying technology dependencies. Because Cursor is built on Visual Studio Code and relies on frontier models to deliver its core features, its economics are tied to relationships with model providers such as OpenAI and Anthropic. An acquirer would likely want clarity on how those licensing and supply arrangements survive a change of ownership, since the value of the product depends heavily on continued access to capable models at predictable cost. Ownership by a company outside the traditional software industry could also prompt questions about data handling and how enterprise customers respond, factors that are typically weighed before a deal is finalized.

It is worth placing the reported talks in the context of recent industry activity around AI coding tools. The category has become intensely competitive, with GitHub Copilot from Microsoft, Amazon's developer assistants, and rivals such as Windsurf, Replit, and Tabnine all vying for developer mindshare. Consolidation and high-profile talent moves have been a recurring theme, as larger players seek to secure both the products and the engineering teams behind them. Against that backdrop, a very large bid for Cursor would fit the pattern of established companies paying premium valuations to enter or defend a position in AI-assisted software development, even if the specific pairing with SpaceX is unexpected.

Readers should note the provenance of this report. The item is presented as an explainer accompanying a Japanese-language YouTube video, and the details—including the valuation figure and the description of the deal as incomplete—are framed as reported rather than confirmed by the companies. As of the stated publishing date, there does not appear to be an official closing announcement, so the figures and terms should be treated as provisional and subject to change until confirmed by the parties or by regulatory filings.

For those following the space, the broader takeaway is more durable than any single transaction. The reported interest underscores how strategically important AI development tools have become, and how the gap between announcing advanced talks and completing a deal can be wide, especially when antitrust review, financing, and technology dependencies all have to align. Whether or not this particular acquisition closes, the episode illustrates both the premium valuations attached to leading AI editors and the practical friction that large, cross-industry deals must overcome before they are truly done.
