SpaceX IPO Filing Reveals $1.45B Bitcoin Treasury

SpaceX formally entered the public markets on May 20, 2026, filing IPO paperwork with the U.S. Securities and Exchange Commission and planning to list on Nasdaq under the ticker SPCX. The long-anticipated filing did more than launch a potential record-setting offering — it pulled back the curtain on a substantial Bitcoin position that had largely escaped precise public accounting.

Bitcoin on the Balance Sheet

The company held 18,712 Bitcoin as of December 31, acquired at a total cost of $661 million, or roughly $35,000 per coin, according to the S-1 filing. At current market prices, that position is valued at approximately $1.45 billion, representing a significant unrealized gain on the original cost basis.

Key figures from the disclosure:

• 18,712 BTC held as of Dec. 31, with the position unchanged from year-end 2024
• $661 million total acquisition cost (~$35,000 average per coin)
• ~$1.45 billion current market value
• $955 million unrealized paper gain recorded in 2024
• $112 million unrealized loss recorded in the prior year (2025)

The disclosure places SpaceX among the largest known corporate Bitcoin holders, with a stack above 18,000 BTC ranking it approximately seventh among tracked corporate treasuries and ahead of Coinbase. The filing notes that the holdings continue to be held with third-party custodians.

Filling in an On-Chain Gap

The S-1 resolves a long-running discrepancy between SpaceX's actual holdings and what on-chain researchers had estimated. On-chain movements last year had suggested the company consolidated roughly $143 million worth of Bitcoin into a single wallet, leading some analysts to theorize a balance of around 8,285 BTC — a figure that apparently failed to capture all of the company's wallets. Arkham showed roughly 8,280 BTC tied to SpaceX addresses on the day of filing, while the S-1 provides investors with the company's formal year-end accounting figure.

SpaceX initially added 25,724 Bitcoin to its balance sheet during the pandemic-era crypto market surge, suggesting the company trimmed a portion of its original stockpile in subsequent years.

A Record-Scale Offering

The Bitcoin disclosure arrives as a footnote to what could be the largest IPO in history. SpaceX is seeking to raise as much as $75 billion and is valued at more than $2 trillion, which would surpass Saudi Aramco's $29.4 billion offering in 2019 — currently the largest IPO on record. Goldman Sachs and Morgan Stanley are serving as lead underwriters, with Bank of America, Citigroup, and JPMorgan Chase participating as joint bookrunners.

SpaceX's broader filing is centered on Starlink revenue, reusable rockets, xAI exposure, and long-range ambitions around Mars and space-based infrastructure. The company reported $18.67 billion in revenue last year, with most of it coming from Starlink, and identified a total addressable market of $28.5 trillion across its businesses.

SpaceX is expected to begin marketing the offering to investors on June 4, with the IPO price potentially set as early as June 11. For the crypto market, the filing marks a meaningful milestone: Bitcoin's presence on the SpaceX balance sheet moves from anecdote to audited disclosure — attached to one of the most closely watched listings in years.
