SpaceX is officially buying Cursor for $60 billion

SpaceX will acquire AI coding platform Cursor for $60 billion, the company announced, placing the tool under its xAI subsidiary as it moves to compete with OpenAI and Anthropic in enterprise artificial intelligence [1][8]. The deal, disclosed in an SEC filing, is expected to close during the third quarter of 2026 [1]. The takeover follows an unusual arrangement announced in April in which SpaceX agreed to either acquire the programming platform for $60 billion or pay a $10 billion breakup fee [1]. The company had delayed finalizing the transaction while completing its initial public offering [1]. That IPO, which raised $86 billion on June 12, 2026, was the largest in history and made Elon Musk the first U.S. dollar trillionaire [3]. Cursor, developed by San Francisco-based Anysphere, Inc., is an AI coding agent that allows users to edit code, search codebases, and complete programming tasks using natural-language instructions [8]. The startup, founded in 2022 by Michael Truell and others, achieved a $29.3 billion valuation and surpassed $3 billion in annual recurring revenue by early 2026 [8][9]. SpaceX will place Cursor under its xAI subsidiary, which already operates the Grok chatbot and the social network X [2][8]. The company has structured itself into three divisions: Space, Connectivity, and Artificial Intelligence [3]. Musk has expressed frustration with xAI's coding product, which trails tools like Anthropic's Claude Code and OpenAI's Codex [1]. Anthropic's Claude series, trained using a technique called "constitutional AI" to improve ethical compliance, has faced its own challenges — the Department of Defense designated the company a "supply chain risk" in 2026 after it refused to remove contractual prohibitions on mass domestic surveillance and fully autonomous weapons [7]. A federal judge issued a temporary injunction against that designation on March 26 [7]. SpaceX's acquisition of Cursor marks the latest consolidation in Musk's technology holdings. In February 2026, SpaceX acquired xAI, which had itself purchased X Corp. in March 2025 in an all-stock deal valuing the social media platform at $33 billion [4][3]. The social network, originally founded as Twitter in 2006, has changed ownership six times and three times under Musk alone [4]. The Cursor acquisition comes amid a broader push into enterprise AI tools as demand surges for automated coding platforms and "vibe coding" practices gain traction in the software industry [1].
