SpaceX Tesla bitcoin: 18,712 plus 11,509 coins as of June 30

Added together, the bitcoin counts SpaceX and Tesla filed for June 30, 2026, come to 30,221 coins. SpaceX held 18,712 at a cost basis of $661 million and a fair value of $1.10 billion; Tesla held 11,509 at an acquisition cost of $386 million. Against Bitbo's public-company list of Oct. 20, 2026, the sum would rank sixth, behind Metaplanet and ahead of Bullish. Musk said on SpaceX's Oct. 20 earnings call that special committees at both companies are discussing a combination, with no terms agreed.

If you track how much bitcoin sits on corporate balance sheets, 30,221 is a June 30 snapshot of two separate companies. It becomes one holding only through a deal.

The 30,221 bitcoin are a June 30 count

Both counts come from the quarterly Form 10-Q reports the companies file with the SEC, SpaceX's and Tesla's for the quarter ended June 30, 2026. Each count matches the one at Dec. 31, 2025. SpaceX's fair value is the market price of its coins on the reporting date, while the cost basis is what it paid. Tesla's coins make up the majority of its digital assets.

Sixth among public companies, far behind Strategy

On Bitbo's bitcoin treasuries list, last updated Oct. 20, 2026, five public companies hold more than 30,221 bitcoin: Strategy with 848,517, Twenty One with 37,229.7, Strive with 35,595, Marathon with 35,577 and Metaplanet with 35,102. Bullish follows with 24,340. The public-company ranking gives no date per company, and Bitbo still files SpaceX as private, though SpaceX has traded on Nasdaq as SPCX since its June 2026 IPO.

The gap to the top is wide: Strategy's 848,517 coins are about 28 times the combined June 30 count.

SpaceX's third quarter names no bitcoin

SpaceX's third-quarter results release reports digital assets as one balance-sheet line in dollars: $1.57 billion on Sept. 30, 2026, against $1.64 billion on Dec. 31, 2025.

The cash flow statement records a $64 million unrealized loss on digital assets for the first nine months of 2026, which matches the decline in that line. An unrealized loss is a drop in market value that no sale has locked in.

If the line still consists of the same bitcoin, the step from the June 30 fair value of $1.10 billion to the Sept. 30 line of $1.57 billion is a rise of about $475 million. That is a change in the value of a holding, not an inflow of money.

The release breaks out no digital-asset share of SpaceX's $4.40 billion third-quarter net income.

A deal would need committees, a proposal and a high vote

Musk, CEO of both companies, called a combination a good idea on the call but said shareholders have to back it, according to a Motley Fool transcript. He also cautioned against treating a merger as certain.

The committees he described consist of independent directors and were formed at shareholders' request. As a conflicted party, Musk cannot take part in their talks. The committees would have to produce a proposal, which would then go to a shareholder vote.

For Tesla, he put the bar at 50% of all shares, not only of the shares voted, and called it a high hurdle.

SpaceX's debt carries a merger clause of its own. Its 10-Q describes $25 billion of senior notes issued in June 2026, bonds with priority in repayment, that restrict fundamental changes. That restriction is limited to a merger in which SpaceX is not the surviving entity, the company that continues to exist, outside certain jurisdictions.

The two companies already share a financial tie. In March 2026, Tesla invested $2.00 billion in SpaceX common stock, a stake of less than 1%, as its 10-Q shows. The stake began as a preferred-share investment in xAI.

How you can tell whether the count still holds

Tesla was scheduled to report third-quarter results after the market close on Wednesday, Oct. 21, 2026, according to CoinDesk and CNBC. That report can replace Tesla's June 30 count with a newer one.

For SpaceX, the third-quarter Form 10-Q is the filing that can put a coin count behind the $1.57 billion line. On the deal, a proxy or 8-K filing from either company would show what the committees propose.
