TLDR
SpaceXs IPO filing shows it holds about 18,700 Bitcoin, making it one of the largest corporate BTC treasuries and giving its IPO a clear crypto angle.
- SpaceX disclosed 18,712 BTC, bought for $661 million at roughly $35,000 per coin, worth around $1.31.5 billion depending on Bitcoins price.
- That stash puts SpaceX among the top corporate Bitcoin holders, ahead of Teslas BTC stack and just below players like MicroStrategy.
- The IPO will give investors indirect exposure to a major Bitcoin treasury, but also raises questions about whether SpaceX will keep, add to, or sell its BTC over time.
Deep Dive
1. What SpaceX Actually Disclosed
In its S-1 IPO registration, SpaceX reported holding 18,712 Bitcoin as of the end of 2025, purchased for a total of $661 million at an average price around $35,000 per BTC. Reports based on the filing put the positions value near $1.45 billion at late December prices, with the fair value marked at about $1.29 billion at a later balance date as Bitcoin traded lower, and closer to $1.45 billion again at recent prices as BTC has risen.
The filing also notes that the company has ownership of and control over its digital assets and uses third?party custodians to hold its Bitcoin, confirming this is a deliberate treasury position rather than a minor side bet.
2. Why This Matters For Bitcoin
Multiple analyses of the S-1 say 18,712 BTC would rank SpaceX roughly seventh among corporate Bitcoin holders, placing it ahead of Teslas roughly 11,500 BTC but far below MicroStrategys hundreds of thousands of coins. That means two of Elon Musks flagship companies both have large BTC treasuries, reinforcing the idea that Bitcoin is part of his broader corporate strategy rather than a one?off experiment.
SpaceX began buying Bitcoin in early 2021, around the same time as Tesla, and has held through big drawdowns, recording an unrealized loss in 2023 and a large paper gain in 2024 before todays bigger mark?to?market profit.
SpaceX effectively validates Bitcoin as a treasury asset at the scale of a trillion?dollar tech and aerospace company, even though BTC still represents well under 1 percent of its implied valuation.
3. What To Watch Around The IPO
SpaceX is targeting what could be the largest IPO in history, with reports of a planned raise around $75 billion and a valuation in the 1.52 trillion dollar range. Buying SpaceX stock will give public investors indirect exposure to its BTC holdings on top of its rockets, Starlink and AI businesses.
Key open questions are whether SpaceX will keep its Bitcoin allocation stable, scale it up like MicroStrategy, or eventually trim it under public?market pressure if volatility or drawdowns become uncomfortable for shareholders. Any future S-1 amendments, quarterly reports or management commentary that change the BTC line item could become catalysts for both the stock and Bitcoin sentiment.
Conclusion
SpaceXs IPO filing turns years of speculation into hard numbers, revealing a roughly billion?plus dollar Bitcoin position accumulated at around $35,000 per coin. That makes Bitcoin a small but real part of one of the most watched IPOs ever, adds another high?profile corporate name to the BTC?treasury club, and creates a new link between Bitcoins narrative and one of the biggest listings coming to public markets.
