SpaceX just pulled off something no company has done before: a $75 billion IPO. The June 12 debut on Nasdaq under the ticker SPCX wasn’t just the largest initial public offering in history. It also came with a surprise that sent the crypto world into overdrive, a disclosure revealing the company holds 18,712 Bitcoin on its balance sheet.

Shares were priced at $135 each, with 555.6 million shares sold to investors. The stock opened at $150 and closed its first day of trading at $160.95, a 19% pop that pushed SpaceX’s market capitalization past $2.1 trillion.

The Bitcoin angle Wall Street didn’t see coming

Buried in SpaceX’s IPO filing was a detail that matters enormously for crypto markets. The company disclosed Bitcoin holdings of 18,712 BTC, valued between $1.29 billion and $1.45 billion as of March 31, 2026. SpaceX categorized the position as non-core treasury, meaning it’s not central to operations but significant enough to warrant disclosure.

That makes SpaceX’s debut the largest Bitcoin position ever associated with an IPO.
