SpaceX shares have cooled off after a blistering debut that saw the stock surge roughly 19% on its first day of trading. After climbing into the $190s in the following session, shares pulled back about 3%.

But here’s the thing. Buried in SpaceX’s balance sheet is a detail that makes this more than just a space-sector story: the company holds 18,712 BTC as a treasury reserve, worth approximately $1.3 billion at the time of filing. That makes SpaceX one of the largest corporate Bitcoin holders now trading on public markets.

The IPO by the numbers

SpaceX priced its shares at $135 on the Nasdaq under the ticker SPCX, debuting around June 12, 2026. The first-day close landed between $160.95 and $161, a 19% pop that validated what had been months of sky-high anticipation.

The initial raise came in at roughly $75 billion. With the overallotment option exercised, that figure swelled past $85 billion, making it the largest US IPO by a wide margin. The company’s market capitalization briefly exceeded $2 trillion during the post-debut rally.
