Fresh off a historic initial public offering, SpaceX announced Tuesday that it has entered a definitive agreement to acquire Anysphere Inc., the parent company of the popular artificial intelligence (AI) coding assistant Cursor, in an all-stock transaction valued at $60 billion.
The acquisition cements SpaceX’s sudden transformation into an AI powerhouse, following its merger with Elon Musk’s xAI venture in February. The deal is expected to close in the third quarter of 2026, subject to regulatory approvals.
Under the agreement, Cursor common and preferred stock will convert into SpaceX Class A common stock. The exchange ratio will be determined by the volume-weighted average closing price of SpaceX stock over the seven trading days prior to closing.
Neither SpaceX nor Cursor immediately responded to requests for comment.
The transaction materializes an option SpaceX unveiled in April, which gave the aerospace-and-AI giant the choice to either buy the San Francisco-based startup for $60 billion or pay $10 billion for a collaborative partnership. A regulatory filing revealed that SpaceX will face a $10 billion termination fee under specific circumstances, and a $4 billion fee if antitrust issues scuttle the deal.
The acquisition aims to supercharge SpaceX’s Grok AI business, which analysts note has lagged frontier market leaders like Anthropic, OpenAI, and Google. By absorbing Cursor, SpaceX gains an immediate foothold in the lucrative enterprise software market.
“An independent coding tool moving inside a frontier-model competitor’s stack converts a model-agnostic layer into a captive one. Cursor’s pull with enterprises rested on neutrality across models and clouds, and that neutrality is what the deal removes,” said Mitch Ashley, vice president and practice lead for Software Lifecycle Engineering and AI-Native Software Engineering at The Futurum Group. “Enterprise buyers now re-underwrite Cursor as a single-owner dependency. The procurement question moves from what the tool does to whether a newly public conglomerate with no enterprise software track record will steward a developer layer whose model partners it now competes against.”
Launched in 2022, Cursor has pioneered the vibe coding trend—allowing developers to autonomously generate software. The platform brings a prestigious enterprise client base, including Adobe Inc., Stripe Inc., and NVIDIA Corp., and boasts $2.6 billion in annualized business-to-business revenue.
Wall Street responded with euphoria. In the wake of the announcement, SpaceX shares — trading on the Nasdaq under the ticker SPCX.O — surged nearly 10% in premarket trading to $211.27. The rally represents a 56% climb from its $135 IPO price set just last Friday, pushing SpaceX’s market capitalization to a staggering $2.9 trillion.
With that jump, SpaceX has overtaken Amazon.com Inc. to become the world’s fifth-most valuable public company, a milestone that officially makes Musk the world’s first trillionaire.
The tie-up leverages immense infrastructure advantages. Cursor previously indicated that aligning with SpaceX would grant it access to xAI’s massive, million-H100-equivalent Colossus supercomputer cluster in Memphis, Tenn., solving the compute-shortage constraints that had previously hampered its growth.
While SpaceX has recently secured lucrative cloud-capacity rental deals with Google and Anthropic worth $26 billion annually, those contracts contain 90-day termination clauses. This gives SpaceX the flexibility to reclaim data center capacity to fuel Cursor’s growth if necessary.
Despite the market optimism, the $60 billion purchase underscores SpaceX’s aggressive, high-burn strategy. Financial filings show the company is not yet profitable, posting over $9 billion in losses across 2025 and 2026 due to capital-intensive investments in rocket manufacturing, Starlink infrastructure, and AI data centers.
