Musk intercepted Cursor from Anthropic for $60 billion in SpaceX stock: a strategic breakdown of the deal
In the world of high technology and artificial intelligence, an event has occurred that could radically change the balance of power ahead of one of the most anticipated IPOs of the year. Elon Musk acquired Anysphere, the developer of the popular AI tool for programmers, Cursor, for $60 billion. Key detail: the deal was paid for exclusively with SpaceX shares, and it was closed literally just days before Anthropic's stock market debut.
Cursor was not just another startup. This tool became the primary monetization channel for Anthropic's Claude model. Every engineer using Cursor to write code was, in essence, a paying customer of Anthropic "under the hood." The flagship Composer feature, powered by Claude Sonnet, spawned an entire phenomenon — "vibe coding," where a programmer describes a task in words, and the AI writes the code. A significant portion of Silicon Valley and engineering teams from the Fortune 500 were actively using Cursor.
How the deal went down and why it's a blow to Anthropic
The mechanics of the deal are striking in their audacity. Not a single dollar in cash changed hands. All $60 billion was paid for with SpaceX shares. Musk used the SpaceX IPO, which took place on June 12, as a "printing press": the company's shares rose from $135 to $211 apiece by the start of the following week. SpaceX investors faced dilution of approximately 3.4% due to the issuance of new shares, which were immediately directed towards the purchase of Cursor.
Why is this critical for Anthropic? Cursor was one of the largest external consumption channels for Claude. Anthropic's corporate revenue surged in 2025 largely thanks to every engineer who paid for Claude through a Cursor subscription. Now, this channel has been cut off by Musk. According to data from the service Ramp, Cursor's share among corporate clients was already declining from 41% in June 2025 to 26% in May 2026, losing ground to GitHub Copilot and Amazon Q. Musk bought a company that was starting to lose its position and paid 20% more than the $50 billion valuation that investors like Andreessen Horowitz considered aggressive.
Musk's motives and risks for Anthropic's IPO
Strategically, this looks like a direct attack on Anthropic's position. Musk's own AI division, xAI, is experiencing serious difficulties: by the end of March 2026, all 11 co-founders had left the company, and Musk himself admitted that xAI was "built incorrectly from the start." To give SpaceX a compelling AI story before its public market debut, the easiest path was to buy a brand that engineers already trust.
Now, Anthropic finds itself in a difficult situation. The lost revenue stream from Cursor must be urgently replaced to convince Wall Street of the business model's sustainability before the IPO. If the company cannot quickly demonstrate alternative sources of growth, one of the most anticipated AI listings this year could face a serious threat.
Expert opinion: This deal is a classic example of a "scorched earth strategy" in the tech war. Musk didn't just buy an asset; he deprived a key competitor of a major client and distribution channel just days before its stock market debut. For Anthropic, this is a moment of truth: can the company prove that its value lies not in one external partner, but in the fundamental superiority of the Claude model? Investors should closely watch how Anthropic restructures its monetization strategy in the coming quarters.
