SpaceX discloses 18,712 BTC position with $661M cost and $1.3B+ market value in S‑1 ahead of IPO

SpaceX disclosed in its S‑1 registration statement filed with the U.S. SEC that it holds 18,712 Bitcoin (BTC), a position purchased at a total cost of about $661 million (roughly $35,000 per BTC) as of December 31, 2025 ^{[1] [2]}.

Reported market valuations of that holding vary by outlet, with estimates cited at roughly $1.29 billion and about $1.45 billion based on contemporaneous BTC prices; some coverage notes the stash places SpaceX among the largest Bitcoin whales ^{[1] [3] [2]}.

The crypto disclosure appears as part of SpaceX’s IPO filing, which includes broader financial and operational details as the company prepares for a public listing ^{[4] [1]}.

The S‑1 makes the company’s digital‑asset exposure a transparent line item on its balance sheet ahead of the Nasdaq debut, with the filing itself serving as the primary source for the disclosed amounts ^{[1] [4]}.
