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.

Musk becomes the world’s first trillionaire

The IPO also created a personal financial milestone for Elon Musk. His SpaceX stake was valued at approximately $690 billion at the IPO price. Combined with his holdings in Tesla and other ventures, that pushed his total net worth past $1 trillion, making him the first person to cross that threshold.

The IPO received strong institutional interest, surpassing previous records by more than three times. SpaceX’s implied pre-IPO valuation sat in the range of $1.77 trillion to $1.8 trillion. At its peak during the trading session, the market cap exceeded $2.25 trillion.

What this means for crypto investors

SpaceX’s Bitcoin treasury disclosure matters far more for crypto markets than another corporate earnings report mentioning blockchain. This is a company that just executed the biggest IPO in human history telling the world it holds nearly 19,000 BTC.

SpaceX classified its Bitcoin as non-core treasury, which means the company could liquidate it without strategic consequences. If SpaceX ever decides to sell 18,712 BTC, that’s a market-moving event. For a company that doesn’t depend on Bitcoin for revenue, the position is essentially an option, valuable when prices rise, disposable when priorities shift.
