SpaceX's recent IPO filing has unveiled that the company holds a significant bitcoin reserve valued at $1.3 billion, more than double previous estimates. This revelation highlights SpaceX's substantial investment in cryptocurrency, positioning it as a major player in the corporate adoption of bitcoin as a reserve asset. The company's bitcoin holdings, acquired at an average cost of $35,000 per coin, remain profitable despite a 37% decline from January highs. As SpaceX transitions to a public company, its bitcoin position will be subject to fair-value accounting, requiring quarterly reports to reflect market fluctuations. This move mirrors Tesla's approach, another Elon Musk-led company, which has also maintained its bitcoin holdings through market volatility. SpaceX's stance provides a notable example for other large corporations considering bitcoin as a reserve asset, demonstrating resilience in the face of market changes.
