SpaceX has officially confirmed its 18,712 BTC position remains intact on its balance sheet following the record IPO, as confirmed in its June 15, 2026 Form 8-K filing with the US Securities and Exchange Commission. The filing, which outlines how SpaceX intends to deploy IPO proceeds, confirms what the earlier S-1 registration statement had already flagged: the Bitcoin treasury position carries a cost basis of approximately $661 million (roughly $35,300 per coin) and was marked at a fair value of $1.293 billion as of March 31, 2026. At current prices, this figure sits closer to $1.45 billion, representing a significant increase from the $1.19 billion valuation at the time of filing.
SpaceX completed the largest initial public offering on record, raising $75 billion and disclosing 18,712 BTC in its filing. The company priced shares at $135 each, selling approximately 555.6 million shares at an implied valuation near $1.77 trillion. The stock opened at $150 on its Nasdaq debut and closed the first session at $160.95, representing a 19% gain from the IPO price after touching an intraday high of $176.52. The Bitcoin position was more than double the 8,285 BTC that trackers had estimated before the filing, with the company directing capital toward expansion of AI compute infrastructure, enhancements to launch infrastructure and vehicles, and increases in satellite constellation capacity.
According to the latest SEC filing, SpaceX paid approximately $661 million for its Bitcoin holdings, an average of $35,320 per coin. With Bitcoin trading near $65,000, the reserve was worth roughly $1.45 billion at the time of the filing. As reported by CoinDesk, BitcoinTreasuries now ranks SpaceX eighth among public corporate holders globally, ahead of Coinbase. Tesla, which kept 11,509 BTC untouched through the first quarter, lifts Musk's combined corporate total to 30,221 BTC, with only four public companies holding more. The company has held its Bitcoin position since first accumulating in 2021, maintaining flat through the 2022 bear market, 2024 halving cycle, and now its own IPO.
The most significant development is the fair-value accounting rules that make SpaceX's Bitcoin position publicly visible and accountable. Under these new rules, SpaceX must mark its Bitcoin holdings to current market value every quarter, creating a live feed of crypto volatility for public investors. The company's 18,712 BTC position, valued at approximately $1.45 billion at the time of filing, represents a small fraction of SpaceX's overall business but carries major implications for corporate Bitcoin adoption. This transparency represents a quiet milestone, as it marks the largest Bitcoin treasury ever attached to a public listing that must now report its value publicly. The $10,000 move in BTC price translates to roughly $187 million in unrealized gain or loss on SpaceX's books.
Trader Scott Melker, host of The Wolf of All Streets podcast, sees the fresh capital as an opportunity for further Bitcoin accumulation. The filing classifies the Bitcoin, representing about 1.8% of total assets, as a strategic reserve for excess cash. However, history suggests caution, as SpaceX previously wrote down its holdings and sold part of its position during the 2022 downturn, while competing priorities include Starlink expansion, Starship development, and continued operating losses. The real test will come in SpaceX's first public earnings reports, where Bitcoin-driven earnings volatility could impact the stock's performance.
