SpaceX disclosed in its S-1 filing that, as of March 31, 2026, the company held 18,712 bitcoin at a total cost basis of approximately $661 million — an average acquisition price of around $35,300 per coin. At quarter-end, the holdings carried a fair value of approximately $1.293 billion.
Why it matters
The disclosure places SpaceX among the largest publicly identifiable corporate holders of bitcoin, a tier previously dominated by MicroStrategy and a handful of miners. The average cost basis of $35,300 implies SpaceX accumulated during a window when BTC was trading well below current levels, leaving roughly $632 million in unrealized gains on the position. The filing also formalises what had been long-rumoured corporate exposure attached to Elon Musk's venture empire.
Market impact
Institutional-grade disclosures from non-crypto-native corporates tend to reinforce the legitimacy narrative for allocators still building their thesis. Watch for follow-on filings in the same cohort and for any commentary from SpaceX on whether the position is treasury, strategic, or opportunistic — the framing will colour how the market reads the next data point.
