SpaceX Acquires AI Coding Tool Cursor for $60 Billion in All-Stock Deal Days After IPO

Just three days after its blockbuster IPO, SpaceX announced a $60 billion all-stock acquisition of Cursor, the AI-powered coding assistant, signaling an aggressive push into artificial intelligence. The deal would have Cursor stakeholders receive SpaceX equity, with the share count calculated using the volume-weighted average closing price over seven trading days before the merger closes — expected in Q3, per an SEC filing.

SpaceX's market cap surged past $2.75 trillion on Tuesday, overtaking Amazon and giving the company enormous currency to deploy in M&A without heavy cash outflows. Billionaire investor Bill Ackman called out this dynamic explicitly, arguing that SpaceX's sky-high valuation makes its stock a powerful acquisition tool — each deal costs relatively little in actual dilution precisely because the shares are worth so much. He framed the company's ability to do accretive acquisitions as a core part of its long-term value proposition.

The strategic rationale centers on AI. SpaceX and Cursor have reportedly been jointly training an AI model for several months under a SpaceXAI initiative, with that model set to debut on both the Cursor platform and xAI's Grok Build. Elon Musk, in characteristically sweeping terms, predicted that AI will reach what he called 'Stockfish-level' coding ability — a reference to the world's strongest chess engine — and extend to generalized computer use. The acquisition is framed as a vehicle to accelerate frontier AI model development.

The deal represents one of the largest AI acquisitions on record and underscores how SpaceX's IPO has immediately transformed it into a major player in the broader tech M&A landscape — not just a rocket company. SpaceX stock has been volatile in early trading, which is notable given that the Cursor deal's share price is pegged to a seven-day average, meaning any price swings before closing will directly affect the deal's effective value.
