For Elon Musk’s company, it’s a rounding error against a valuation of over $1.8 trillion: small enough that the stock will never trade on it, yet large enough to normalize the asset in a way no dedicated vehicle can.
For years, onchain analysts estimated SpaceX held about 8,300 bitcoin. The S-1 then revealed the real number was more than twice that, meaning one of the most scrutinized private companies in the world held a billion-dollar bitcoin position, and the public’s best guess was off by half until securities law forced the answer.
Now the position lives under public company rules.
Fair-value accounting means every quarterly report marks bitcoin to market, recording gains and losses whether or not SpaceX trades the coin. Tesla showed how that looks in a drawdown, booking hundreds of millions in paper losses on a position it wasn’t selling.
SpaceX arrives with bitcoin 37% already below its January high, though its roughly $35,000 cost basis means the stake is still up about 80% from its initial buys.
Neither Tesla nor SpaceX — both Elon Musk-owned firms — have ever shown an appetite for trading its stack. These companies continue to hold (at least for now) bitcoin through public earnings cycles and analyst questions, while the position swings, hands every Fortune 500 finance chief a working example of a mega-caps that treat bitcoin as a reserve asset, absorbs the earnings noise and moves on.
