SpaceX went public on June 12, 2026, and broke every record worth breaking. The company listed on Nasdaq under the ticker SPCX, raising between $75 billion and $86 billion in what instantly became the largest IPO in history. The resulting valuation landed somewhere between $1.75 trillion and $2 trillion, a number so large it effectively made Elon Musk the world’s first USD trillionaire.
Four days later, SpaceX spent $60 billion of that freshly minted stock to buy AI coding startup Cursor. If you were wondering what the money was for, now you know.
The numbers behind the rocket-fueled debut
Shares were priced at $135 ahead of the listing. They opened at $150 and closed their first day near $160 to $161, a roughly 19% pop that would be impressive for a normal IPO. For one raising north of $75 billion, it borders on absurd.
The pre-IPO valuation had already reached approximately $1.25 trillion during SpaceX’s final private funding rounds. Post-IPO market cap estimates have ranged from $2.1 trillion to $2.5 trillion, putting SpaceX in the same conversation as Apple and Microsoft.
