For Elon Musk’s company, it’s a rounding error against a valuation of more than $1.8 trillion: small enough that the shares will never trade on it, but large enough to normalize the asset in a way that no dedicated vehicle can.
For years, on-chain analysts estimated that SpaceX had around 8,300 bitcoins. The S-1 then revealed that the real figure was more than double that, meaning that one of the most scrutinized private companies in the world had a billion-dollar bitcoin position, and the public’s best guess was off by half until securities law forced the answer.
Now the position is governed by the rules of public companies.
Fair value accounting means that each quarterly report marks bitcoin on the market, recording gains and losses, whether or not SpaceX trades the currency. Tesla showed what that looks like in a drawdown, booking hundreds of millions in paper losses on a position it wasn’t selling.
SpaceX arrives with bitcoin already 37% below its January high, although its roughly $35,000 base cost means the stake is still 80% above its initial purchases.
Neither Tesla nor SpaceX (both companies owned by Elon Musk) have ever shown an appetite to commercialize their stack. These companies continue to hold (at least for now) bitcoin through public earnings cycles and analyst questions, as the position oscillates, handing every Fortune 500 CFO a practical example of mega-cap that treats bitcoin as a reserve asset, absorbs the earnings noise, and moves on.
