SpaceX Files Public S-1 for Record IPO, Forcing 8,285 BTC Into the Light

The prospectus, signed by chief executive Elon Musk from the company’s 1 Rocket Road headquarters in Starbase, Texas, follows a confidential draft filed on April 1 and lines up with Reuters’ reported timeline of a June 11 pricing and a June 12 Nasdaq debut under ticker SPCX.

The headline numbers are familiar to anyone who has tracked the pre-IPO chatter. SpaceX is targeting a valuation between $1.75 trillion and $2 trillion and a capital raise of up to $75 billion — roughly two-and-a-half times Saudi Aramco’s $29 billion record from 2019. A 21-bank syndicate led by Morgan Stanley, Bank of America, Citigroup, JPMorgan Chase and Goldman Sachs is running the book, with up to 30% of shares carved out for retail allocation, approximately three times the standard for an offering of this size. The dual-class share structure leaves Musk and insiders with Class B super-voting stock; Musk himself is not selling a share.

The Space X Bitcoin Treasury

For crypto market participants, however, the single most material line in the prospectus is one most aerospace analysts will skim past: SpaceX’s bitcoin treasury.

According to on-chain data from Arkham Intelligence, SpaceX holds 8,285 BTC across 43 addresses in Coinbase Prime custody, a position that has been essentially unchanged since June 2022. At bitcoin’s current spot price of roughly $77,500, that stack is worth approximately $642 million. The company has never publicly confirmed the figure — it didn’t have to as a private entity — but the S-1 should formally crystallise the holding in audited form for the first time. As Arkham put it bluntly on X earlier this week, “SpaceX is about to be the 6th largest public company in the world.”

SpaceX accumulated roughly 28,000 BTC at the 2021–2022 peak, then trimmed about 70% of that position during the bear market — a sequence that, when leaked through a 2023 Wall Street Journal report, briefly knocked bitcoin under $25,000 and liquidated more than $386 million of futures. The remaining core position has now ridden through three years of macro turbulence, a February 2026 xAI consolidation and a roughly $5 billion full-year 2025 loss without a single coin moving to an exchange. As one Backpack research note observed, holding a volatile reserve through losses “rather than selling to improve the balance sheet signals that Musk and SpaceX’s leadership view BTC as a long-term treasury reserve.”

That framing matters because of what comes next. Under the FASB’s ASU 2023-08 fair-value accounting standard, which took effect for fiscal years beginning after December 15, 2024, listed companies must now mark bitcoin holdings to market every quarter and route the result straight through earnings. The asymmetric impairment regime that punished Strategy and Tesla through the last cycle is gone — but so is the smoothing. A $10,000 move in BTC will now produce an $83 million swing in SpaceX’s reported net income, irrespective of how many Falcon 9s flew that quarter.

Investors only need to look at the precedent. Strategy, the world’s largest corporate bitcoin holder at 818,334 BTC, booked a $12.54 billion net loss for Q1 2026 driven almost entirely by an unrealised mark-down on its position as bitcoin slid from roughly $87,000 in January to $68,000 in late March. The trade hadn’t changed; the accounting had. SpaceX’s BTC line will be roughly 1% the size of Strategy’s, but the same volatility lever will be pulling on the income statement of a company that, at $2 trillion, would be among the ten largest publicly listed firms in the world.

SpaceX is currently the fourth-largest known private corporate bitcoin holder, behind Block.one, Tether Holdings and Stone Ridge Holdings. Once listed, it slots in behind Strategy as the second-largest public-company holder by coin count and — given the targeted valuation — comfortably the largest by market capitalisation. Tesla, also Musk-controlled, holds 11,509 BTC; the publicly-traded company with the most direct bitcoin exposure to Musk’s broader empire will, post-IPO, be the rocket business.

The structural implications run deeper than the line item. A Nasdaq listing puts SPCX into the path of every passive-equity allocator on the planet. Any index inclusion — particularly the Nasdaq 100 — would force ETFs and pension funds buying the stock for its rocket, satellite and AI exposure to also acquire indirect exposure to bitcoin via the treasury. That second-order channel, which crypto-native analysts have started calling the “Trojan horse” effect, is precisely the kind of institutional inflow vector that the corporate-treasury thesis was built on.

Crypto markets aren’t waiting for the official listing to price this in. Trade.xyz earlier this week launched SPCX-USDC pre-IPO perpetuals on Hyperliquid, opening at a $1.78 trillion implied market cap on a fully diluted share count of 11.87 billion. Open interest pushed past $40 million inside 48 hours.

Two questions now sit on the desks of every crypto-credit and equity analyst running the file. First: how does SpaceX characterise the bitcoin position in the S-1 language itself — strategic reserve, treasury hedge or tradeable asset? The choice will signal management’s intent and, by extension, how durable that 8,285 BTC core is once quarterly mark-to-market hits the earnings call. Second: does the prospectus disclose anything about the xAI consolidation that materially changes the consolidated balance sheet, given that the AI unit was acquired for approximately $250 billion in February and absorbed most of the 2025 loss?

The roadshow is reportedly scheduled to kick off the week of June 8, with Investor Day, pricing on June 11 and listing on June 12. From today, every disclosure that lands on EDGAR is a tradable event. For a market that has spent two years arguing whether corporate bitcoin treasuries are a structural bid or a leveraged accident waiting to happen, SpaceX’s prospectus may be the cleanest test case yet.
