Here's How SpaceX's $60 Billion Cursor Deal Really Works

Former White House AI czar David Sacks confirmed the structure of Elon Musk’s Cursor play on the All-In podcast Friday. By the end of 2026, SpaceX will either acquire the AI coding startup for $60 billion or pay it $10 billion to walk away. Sacks, also a SpaceX investor, framed the $10 billion as the cost of a one-year option on the hottest application in AI. The Hottest Application In AI Cursor, built by Anysphere, has become the one of the leading IDE’s for AI-assisted coding. Its run rate hit $2 billion in February and is projected at $6 billion by the end of 2026, which would triple its top line in under a year. It also defines a category that every foundation model lab now wants to own. Cursor was rumored to be raising at a $50 billion valuation before the SpaceX deal landed at $60 billion. Cursor Trapped Between Codex And Claude Code Cursor’s problem was that it ran on top of OpenAI and Anthropic models, and both providers have spent the last year vertically integrating into coding via Codex and Claude Code. Sacks framed it on the pod as a startup competing against the same companies it depended on for its core product. The xAI alliance gives Cursor a foundation model partner that is not also a competitor, plus access to the 550,000 GPUs in Elon Musk’s Colossus cluster, which is scaling toward one million. In return, xAI gets Cursor’s enterprise install base, training data, and the IDE itself, which Chamath Palihapitiya called the most valuable third-party application layer in AI right now. Palihapitiya is also a SpaceX shareholder. The IPO Math SpaceX is targeting a $2 trillion IPO valuation. A $60 billion stock-for-stock deal at that level lands at roughly a 50% discount on a fully diluted basis if the IPO prints, per Palihapitiya. Musk effectively gets to issue tomorrow’s stock at today’s price to pay for an asset he wants now. Polymarket and Kalshi each have a market on whether SpaceX acquires Cursor this year. They trade at roughly 74% and 83% respectively, though both are thinly traded. The Polymarket contract on a Cursor IPO before 2027 has collapsed from around 15% to 7% on the news. Traders are pricing acquisition, not listing. Tesla Is The Public Proxy Tesla Inc. (NASDAQ:TSLA) is the cleanest public proxy on the Musk AI stack. Walter Isaacson said he now expects a Tesla-SpaceX merger, and Tesla overrode a shareholder vote in January to put $2 billion into xAI before SpaceX swallowed the AI lab in February. If Polymarket’s 74% is right, Cursor’s enterprise revenue and developer base land inside the same orbit Tesla is already paying to ride. If it is wrong, Cursor walks away with the most expensive breakup fee in AI history. Image: Shutterstock
