SpaceX disclosed 18,712 BTC in the S-1 filing tied to its June 12 Nasdaq debut under the ticker SPCX, giving the market its first formal look at the company’s bitcoin treasury. Using the article’s reference price of about $63,000 per bitcoin, the holding is worth roughly $1.18 billion, enough to place SpaceX as the world’s eighth-largest public company holder of BTC.
The filing did more than confirm the position size. It also showed an average acquisition cost of about $35,320, which means the company is sitting on a paper gain close to 100% at the quoted market price. For crypto-focused investors, that treasury disclosure drew as much attention as the IPO itself.
Filing puts SpaceX among the largest corporate bitcoin holders
Based on the Bitcoin Treasuries data cited in the source material, SpaceX now ranks inside the top tier of public companies holding bitcoin. The number is large on its own, and the filing turned what had been market curiosity into a documented balance-sheet position.
The cost basis matters as well. A holding of 18,712 BTC purchased at roughly $35,320 on average leaves SpaceX with a sizable unrealized gain at current prices. The figures are simple, but the scale is hard to ignore.
Adding Tesla lifts the total to 30,221 BTC
The picture gets larger when Tesla is included. The source says Tesla holds 11,509 BTC. Combined with SpaceX’s 18,712 BTC, the two Musk-controlled companies hold 30,221 BTC in total.
Using the ranking framework cited in the report, that combined amount would be large enough to rank fifth among public company bitcoin holders if placed on a single balance sheet. Neither company has built its public identity around a bitcoin treasury strategy, but the aggregate position now stands close to the biggest names in corporate BTC ownership.
Crypto markets focused on the treasury details, not just the listing
The source also notes that SpaceX completed what it described as the largest IPO on record. Shares closed their first trading day at $160.95, up about 19%, and the company’s market capitalization moved past $2 trillion. In crypto markets, though, attention shifted quickly to the bitcoin disclosure in the SEC filing.
Corporate bitcoin exposure is no longer rare, yet a major technology company laying out the exact size, valuation, and cost basis of its holdings in an IPO document still changes how investors read the company’s treasury profile. In SpaceX’s case, the filing made four points clear at once: the amount held, the estimated value, the average entry price, and its place in the global public-company ranking.
