Musk's Strategic Move: How the $60 Billion Cursor Acquisition in SpaceX Shares Reshaped the Landscape Ahead of Anthropic's IPO
The market for AI tools for developers has experienced a tectonic shift. Elon Musk, using SpaceX shares as currency, acquired Anysphere — the creator of the popular AI programming assistant Cursor. The deal was valued at $60 billion, and, most notably, not a single real dollar changed hands: payment was made exclusively in shares of the space giant.
The deal was formalized through a regulatory 8-K filing and closed just days before Anthropic's stock market debut. This is not just a routine acquisition — it is a powerful strategic move that directly struck one of Anthropic's key revenue sources.
Why Cursor Was So Important to Anthropic
Cursor had long been powered by Anthropic's Claude model. Essentially, every engineer using Cursor was a paying customer of Anthropic "under the hood." It was thanks to Claude that the flagship Composer feature became one of the most beloved AI products among programmers. Anthropic's corporate revenue surged in 2025, largely because Cursor became one of the largest external channels for Claude usage across the entire internet.
Moreover, it was with Cursor and Claude that the term "vibe coding" emerged — an approach where a programmer describes a task in plain language, and the AI writes the code. This term was introduced in early 2025 by a researcher experimenting with Composer based on Claude Sonnet.
Musk's Brilliant Financial Engineering
The most interesting aspect of the deal is the payment mechanism. SpaceX shares debuted on the stock exchange on June 12 at a price of $135 each, and by Tuesday were trading above $211. Musk used a few days of stock market frenzy to "print" $60 billion in fresh capital in the form of shares and immediately spent them on a pre-agreed purchase. SpaceX investors, meanwhile, faced dilution of approximately 3.4% — their stake in the company decreased due to the issuance of new shares. The IPO itself became the printing press for this acquisition.
Note the timing: the deal fell precisely in the interval between Anthropic filing its IPO application and setting the offering price. The connection is obvious.
xAI's Problems and the Need for a Quick Solution
Why did Musk take this step? His own AI division, xAI, was experiencing serious difficulties. By the end of March 2026, all 11 of its co-founders had left the company, and Musk himself admitted that xAI was "built incorrectly from the start." For SpaceX to have a compelling AI story ahead of its public market debut, the easiest path was to buy a brand that engineers already trust.
Cursor, according to data from the service Ramp, was losing ground in the race: its share among corporate clients fell from 41% in June 2025 to 26% in May 2026, trailing behind GitHub Copilot and Amazon Q. Investors like Andreessen Horowitz and Nvidia were preparing to invest in Cursor at a $50 billion valuation, considering it aggressive, and Musk paid 20% more — for a company that was, in essence, losing ground.
Market Implications
This is not just a purchase of a coding tool. It is a planned attack on Anthropic's upcoming IPO. Now, the success of one of the most anticipated AI IPOs this year depends on whether Anthropic can quickly convince Wall Street that the lost revenue from Cursor can be replaced.
My expert opinion: Musk played brilliantly, but riskily. Buying Cursor with SpaceX shares is a genius financial trick that simultaneously solves xAI's problem and strikes a blow against a competitor. However, if Cursor continues to lose market share, $60 billion could turn out to be an overpayment. For Anthropic, this is a wake-up call: dependence on a single major client is a fatal vulnerability on the eve of an IPO.
