SpaceX IPO filing exposes bigger Bitcoin bet than expected

SpaceX disclosed 18,712 Bitcoin in its SEC filing, giving investors a clearer view of the company’s digital asset exposure before its planned public listing.

Space Exploration Technologies Corp. reported holding 18,712 Bitcoin in its S-1 registration statement filed with the U.S. Securities and Exchange Commission. The filing showed that Elon Musk’s aerospace company held far more Bitcoin than earlier blockchain-tracking estimates suggested.

The disclosure places Bitcoin inside one of the most closely watched IPO filings of 2026. SpaceX is expected to list on Nasdaq in June, with reports pointing to a possible $75 billion raise and a valuation between $1.75 trillion and $2 trillion.

Filing tops earlier Bitcoin estimates

Before the filing, related crypto.news coverage said SpaceX’s Bitcoin holdings were estimated at 8,285 BTC, based on Arkham-linked wallet tracking. The SEC filing now shows a much larger official balance of 18,712 BTC, more than 10,000 BTC above that estimate.

The filing also shows that SpaceX holds more Bitcoin than Tesla. According to BitcoinTreasuries data, Tesla’s reported balance stands at 11,509 BTC, while SpaceX disclosed 18,712 BTC. Both companies are tied to Elon Musk, who has backed Bitcoin at several points during the past market cycles.

Moreover, SpaceX’s Bitcoin position gives public-market investors another point to watch as the company moves toward listing. The firm is best known for rockets, Starlink satellite internet, and space transport, but the filing also shows a large digital asset position on its balance sheet.

The company said it is targeting the largest actionable total addressable market in “human history.” The filing placed that market at about $28.5 trillion across space, connectivity, and artificial intelligence. That quote gives investors a view of how SpaceX frames its long-term business plan.

Corporate Bitcoin race remains active

SpaceX’s filing arrives as corporate Bitcoin holdings remain a major market topic. Strategy remains the largest public Bitcoin treasury firm by a wide margin. Related crypto.news coverage said Strategy added 24,869 BTC in one week, raising its total holdings to 843,738 BTC.

That puts SpaceX far below Strategy, but still among the more visible corporate Bitcoin holders. If SpaceX lists as planned, its Bitcoin balance would become part of its public-market story alongside revenue, losses, Starlink growth, AI plans, and capital spending.

The filing does not state whether SpaceX plans to buy more Bitcoin, sell part of its holdings, or keep the position unchanged after listing. For now, the SEC document confirms that the company enters its IPO process with a larger Bitcoin balance than the market had previously tracked.
