SpaceX didn’t just pick a ticker for the Nasdaq. It also turned a long-running private estimate into a filed, auditable Bitcoin stash.

Bitcoin Magazine reports that Elon Musk’s SpaceX began trading on the Nasdaq under the ticker SPCX and officially joined the public Bitcoin treasury leaderboard at rank #8 with 18,712 BTC. The number had been building for years, but the public confirmation matters because it’s now anchored to an SEC disclosure.

The filed number that beat prior estimates

SpaceX’s S-1 filing with the Securities and Exchange Commission first disclosed the 18,712 BTC position back in May. Bitcoin Magazine says the filing valued that stake at approximately $1.29 billion at the time of disclosure. It also lists a total cost basis of $661 million, implying an average acquisition price around $35,324 per coin.

Bitcoin Magazine ties that cost profile to timing, saying it suggests SpaceX began accumulating Bitcoin in late 2023 or earlier. Using “today’s prices near $63,000,” Bitcoin Magazine estimates the position is worth about $1.19 billion.

The confirmed figure is a substantial jump versus earlier tracking. Bitcoin Magazine notes that Arkham Intelligence previously tracked SpaceX’s holdings as low as 6,095 BTC. It also cites the BitcoinTreasuries.net May 2026 Corporate Adoption Report, which put the pre-IPO private estimate at 8,285 BTC.

When confirmed disclosures land far above public guesses, the market effect is usually less about “belief” and more about balance-sheet optics. In SpaceX’s case, it re-ranks the company in a way that analysts and trackers will now have to treat as settled.

Where SpaceX sits on the public leaderboard

Bitcoin Magazine frames SpaceX’s disclosure as the second-largest Bitcoin treasury disclosure of May, behind Strategy’s 25,404 BTC in monthly purchases.

BitcoinTreasuries.net described the outcome in advance. In its May report, BitcoinTreasuries.net wrote that it expected SpaceX to “rank among the top ten publicly traded Bitcoin treasuries after its anticipated June 12 IPO.” Bitcoin Magazine says that forecast has now materialized.

rank among the top ten publicly traded Bitcoin treasuries after its anticipated **June 12** IPO.

As of June 11, the live leaderboard cited by Bitcoin Magazine confirms SpaceX at #8 with 18,712 BTC, behind Strive at #7 with 19,032 BTC, and ahead of Coinbase Global at #9 with 16,492 BTC.

Here are the leaderboard points Bitcoin Magazine provides for immediate context.

IPO timing meets a risk-off crypto tape

Bitcoin Magazine also ties the announcement to market conditions. It notes that Bitcoin has fallen more than 50% from its all-time high above $126,000, hovering around $64,000 in recent sessions. It adds that spot Bitcoin ETFs have seen $2.26 billion in outflows over two weeks.

SpaceX’s Bitcoin posture, however, looks less like a short-term trade. Bitcoin Magazine points to the S-1 language: “The Company has ownership of and control over its digital assets, which consist of Bitcoin, and utilizes, and expects to continue to utilize third-party custodians to hold its Bitcoin.” That phrasing is about governance and custody, not momentum.

Bitcoin Magazine also cites Grayscale analysts, who said SpaceX is poised to become the most valuable public company holding Bitcoin by market capitalization. It contrasts that with Strategy, which remains the largest by coin count at “over 843,000 BTC.”

What to watch now

The ledger change already happened, but the next step is operational. Once a company is public, its disclosures, custody arrangements, and treasury actions become harder to misread.

Bitcoin Magazine’s story also includes the IPO mechanics. SpaceX priced shares at $135 on June 11, raising roughly $75 billion and valuing the company around $1.75 trillion. Other reports cited by Bitcoin Magazine suggest possible opening prices of $171 or $155, which would lift valuation to about $2.2 trillion.

That matters because market value will determine how much weight investors assign to SpaceX’s Bitcoin allocation. It won’t change the risk that treasuries can face price volatility, custody risk, and governance constraints.

SpaceX joining the public Bitcoin leaderboard is a filing-backed confirmation, not a rumor. It also reshapes how the market catalogs corporate Bitcoin exposure going forward, whether Bitcoin is having a good week or a bad one.
