Elon Musk has been discussing with close associates the possibility of folding Tesla, SpaceX, and his AI lab xAI into a single combined entity, according to people familiar with the conversations. xAI and SpaceX are already in advanced merger talks, with SpaceX preparing a Nasdaq listing once that deal closes. If Tesla gets added to the structure, the combined company would hold 30,221 Bitcoin, worth roughly $3.3 billion at the current $74,879 print.
That stack is split 11,509 BTC at Tesla and 18,712 BTC at SpaceX, accumulated between Q1 2021 and a series of quiet rocket-company buys through 2022. The combined cost basis sits around $661 million, putting Musk's average price near $35,300 per coin. In other words, even after the recent pullback from $82,000, the merged entity would be sitting on roughly $2.6 billion of unrealized gains on a position most market participants forgot about years ago.
Where 30,221 BTC Ranks Among Public Corporate Holders
Most lists of corporate Bitcoin holders treat Tesla and SpaceX as separate names because they file separately and the SpaceX position never showed up on a public balance sheet (it surfaced through 2023 reporting on internal financials). A merger collapses that distinction and the combined treasury suddenly becomes one of the largest non-mining corporate stacks anywhere.
The current public league table, using data from BitcoinTreasuries.net and SEC filings, looks roughly like this at the top:

A merged Tesla and SpaceX would land at 30,221 BTC. That slots in between Metaplanet and MARA, making it the third-largest public corporate non-mining holder by coin count and pushing Tesla out of the top five entirely as a standalone. The math is simple. Musk has been quietly running one of the largest corporate Bitcoin balance sheets in the world, just spread across two separate companies, and nobody has been counting them together.

Cost basis is where the picture gets even more interesting. Strategy's average buy price now sits in the high $60,000s after years of dollar-cost averaging at higher prices. MARA and Metaplanet have similar mid-cycle entries. Musk's $35,300 average puts the merged entity in a different league. The treasury would be sitting at over 2x cost basis even at current prices, which is the kind of unrealized P&L line that changes how a CFO thinks about capital allocation.
How the xAI-SpaceX Deal Sets Up the Bigger Move
The xAI and SpaceX merger has been in active conversation since late 2025, with the structure reportedly involving SpaceX absorbing xAI and then going public via Nasdaq listing post-merger. That listing is the lever. Once SpaceX is a public company with a real share price, the second-stage move (folding Tesla into the same parent) becomes a stock-for-stock transaction that does not need a cash component.
For Musk specifically, this matters because his Tesla holdings have been diluted by the courtroom fight over his $56 billion compensation package and the broader tug-of-war with the Tesla board on his control over the company's AI roadmap. A combined parent entity solves both problems. Musk already owns a controlling stake in SpaceX and xAI. Folding Tesla into a SpaceX-led structure would functionally give him operating control over Tesla without needing the contested compensation package to clear a courtroom.
Tesla shareholders would receive shares in the combined entity. The question they would have to answer is which version of the company they actually want to own. The choice would be between a pure-play EV maker (current Tesla) and a diversified Musk holding company with rockets, AI, EV, and a $3.3 billion Bitcoin treasury attached. That is not a clean trade for every shareholder, and the proxy fight around any actual merger announcement would be one of the largest in corporate history.
What the Treasury Adds to the Combined Entity
A $3.3 billion BTC position is meaningful to a company the size of SpaceX (last valued around $400 billion in secondary markets) but it is not the headline asset on the balance sheet. What matters more is the optionality.
The merged entity would have the option to repeat the Strategy playbook on a dramatically larger scale. Strategy financed roughly $40 billion of its Bitcoin position with convertible debt and equity raises during 2024 and 2025. A combined Tesla-SpaceX-xAI parent with hundreds of billions in market cap could in principle issue a $5 to $10 billion converts stack and 8x the existing Bitcoin position without straining the balance sheet at all.
Musk has not said anything publicly suggesting he wants to run that playbook. He sold roughly 10% of Tesla's BTC position in Q1 2021 (after the famous Q1 2021 $1.5 billion purchase), saying at the time the sale was to test market liquidity, and has not bought additional Bitcoin on the Tesla balance sheet since. SpaceX accumulated its position separately, and that buying is widely understood to have ended in 2022. Both companies have effectively been long-only holders for over three years.
That status quo could change inside a merged entity if the new parent has reasons to demonstrate balance sheet flexibility, hedge against fiat debasement, or simply mirror what other tech-adjacent public companies are doing with corporate treasury policy. The treasury inheritance does not commit Musk to anything, but it sets up the optionality.
A Short History of Musk on Bitcoin
The arc from 2021 to 2026 is worth retracing because Musk's public stance on Bitcoin has shifted multiple times and the current accumulation reality contradicts a lot of the public commentary.
In February 2021, Tesla disclosed a $1.5 billion Bitcoin purchase and announced it would accept BTC for vehicle payments. Two months later, Tesla suspended BTC payments, citing energy concerns. Musk publicly pivoted to a more skeptical tone through 2021 and 2022. In Q2 2022, Tesla sold approximately 75% of its remaining BTC position, citing balance sheet preservation during the China factory shutdowns.
What did not get reported at the time was that SpaceX was buying Bitcoin during exactly the same window. By the time the SpaceX position surfaced in 2023, the rocket company already held more BTC than Tesla had retained after its big sell. The public narrative was "Musk gave up on Bitcoin." The actual balance sheet position was "Musk consolidated to the company nobody was watching."
Through 2024 and 2025, neither company made any disclosed transactions in either direction. Both have simply held. The dormant 30,221 BTC has compounded in dollar terms while the discourse moved on to other Musk projects.
A combined entity merger announcement would reintroduce the corporate Bitcoin story exactly when the spot ETF complex is rebalancing and the institutional flow is at its most uncertain. The timing is interesting, and the question of intent versus coincidence is one for someone closer to the table to answer.
What Tesla Shareholders Gain or Lose
The shareholder math is not straightforward and the calculus depends on what you owned Tesla for.
Tesla shareholders who own the stock for pure EV exposure lose a clean thesis. A merged entity bundles in rocket revenue, AI compute infrastructure, ad-tier robotaxi unit economics, and a corporate Bitcoin treasury play. None of those are EV exposures, and they each move on different cycles. The combined stock would trade more like a holding company and less like a pure-play industrial bet. The disclosed SpaceX 18,712 BTC S-1 filing is the cleanest reference point for what a merged-entity balance sheet would look like.
Tesla shareholders who own the stock as a Musk long get more concentrated exposure to Musk's operating control without the courtroom overhang. The compensation fight goes away if Musk controls the parent through his existing SpaceX stake. Many Tesla longs would view that as net positive for execution risk.
Tesla shareholders looking at the Bitcoin angle specifically pick up a $3.3 billion treasury position they did not previously have full credit for. Tesla's standalone 11,509 BTC was already on the balance sheet, but the SpaceX 18,712 BTC was effectively invisible to Tesla equity holders. A merger brings that under the same ticker.
Dilution math depends entirely on the exchange ratio, and any concrete numbers would be speculation until a deal structure is announced. The leverage point for activist Tesla shareholders is the EV-pure-play argument. The counterweight from Musk-aligned holders is the operating control argument. That fight is the one that will define the proxy battle if a merger ever gets to a shareholder vote.
Frequently Asked Questions
How big is the combined Tesla-SpaceX Bitcoin position?
30,221 BTC, worth approximately $3.3 billion at $74,879 per coin. Tesla holds 11,509 and SpaceX holds 18,712. Combined cost basis is roughly $661 million, putting the average buy price near $35,300 per BTC.
Where would that rank among corporate Bitcoin holders?
Third-largest public corporate non-mining holder, behind Strategy (605,000+ BTC) and MARA Holdings (47,500+ BTC). A merged entity at 30,221 BTC would sit just above Metaplanet's 26,400 BTC line.
Has Musk confirmed the merger publicly?
No public confirmation has come from Musk or any of the three companies. The reporting describes conversations with close associates rather than an announced deal. xAI and SpaceX are in confirmed advanced merger talks. The Tesla folding sits at the discussion stage for now, and anything beyond that should be treated as speculation.
Could the merged entity buy more Bitcoin going forward?
Operationally the capacity is clearly there for additional accumulation. A combined parent with hundreds of billions in market cap has the balance sheet capacity to follow a Strategy-style convertible-funded accumulation playbook at multi-billion scale. The question of Musk actually running that playbook is separate, and there is no public signal he intends to.
Bottom Line
Musk has been quietly sitting on the third-largest corporate Bitcoin treasury in public markets, split across two companies most analysts track separately, and a merger would collapse that into a single 30,221 BTC line on the parent's balance sheet. The cost basis is $35,300 per coin, which means the position is already up over 2x even after the recent pullback from $82,000. The structural question for traders is what a unified Musk holding company would do with the treasury. It could activate it (Strategy-style convert raises, additional accumulation, balance sheet hedging), or it could continue holding the position dormant the way both companies have for the last three years. If the SpaceX Nasdaq listing closes and the Tesla folding follows, watch the first investor day for any signal on treasury policy. That is when the optionality either becomes a story or stays an asterisk on a 10-K.
