SpaceX stock is climbing again in premarket trading, extending a rally that began with the company’s blockbuster Nasdaq debut last week. The shares, which closed around $160-$161 on their first day of trading after pricing at $135, rose roughly 20% on June 15, the first full session after the IPO. Premarket activity showed another 6%-plus gain as investors kept piling in.

The biggest IPO ever, by a wide margin

SpaceX raised $75 billion by selling 555 million shares at $135 each on June 12, making it the largest initial public offering in history. For context, Saudi Aramco’s 2019 IPO raised about $25.6 billion. SpaceX nearly tripled that.

The stock opened at $150 on its debut day and closed near $161, a gain of roughly 19-20% from the IPO price. That pushed SpaceX’s market capitalization past $2 trillion. It also made Elon Musk the world’s first trillionaire on paper.

The company reported $18.7 billion in revenue for 2025, though it has not yet turned a profit. Retail investors accounted for about 20% of IPO allocations, a notable figure for a deal of this size.
