SpaceX reported third-quarter results on Tuesday 20 October 2026, and buried in a release dominated by $14.6 billion of revenue and $19.6 billion of capital spending was a single line: digital assets of $1.573 billion at 30 September. Tesla reports tonight with a similar line of its own. If you follow bitcoin, these lines are worth reading, but they are easy to misread, because a company that holds some bitcoin is not the same thing as a bitcoin company, and a dollar figure on a balance sheet is not the same thing as a number of coins. This guide gives five checks you can run on any such disclosure, and we score SpaceX’s as a worked example.

One important limit up front: we have not read SpaceX’s Q3 Form 10-Q, only the earnings release as quoted by Bitcoin.com and other news reports, together with earlier coverage of the company’s filings. Where a number comes from a secondary source we say so, and any score below should be revisited once the 10-Q is available.

Why the line exists and why it moves

Under US accounting rules updated in recent years, companies holding bitcoin must generally carry it at fair value, meaning the quoted market price at the balance-sheet date, with changes running through earnings each quarter. Secondary sources describing SpaceX’s June filing cite the rule by different update numbers, so check the filing’s accounting-policy note for the exact reference. The consequence is mechanical: finrep.ai’s reading of SpaceX’s second-quarter 10-Q describes the 18,712 units as a Level 1 measurement at the quoted price, so a rising bitcoin price lifts reported profit and a falling one cuts it, even though no coin was bought or sold.

That is why the same company can report a loss on bitcoin one quarter and a gain the next. In SpaceX’s case, the carrying value went from $1.098 billion at 30 June to $1.573 billion at 30 September, a 43.3% rise, while bitcoin’s Coinbase close went from $58,523.93 to $83,556.14, up 42.8% (our calculation). The two track each other closely because the coin count was unchanged.

Check 1: Units, not just dollars

The question: does the company tell you how many coins it holds? A dollar value alone cannot be separated into price and quantity. If the quantity is not stated, you cannot tell whether a gain came from the market or from purchases, and you cannot compute the value at today’s price. Look for “units” or “BTC” in the notes, not just the balance-sheet caption.

SpaceX:Bitcoin.com reports that the earnings release lists $1.573 billion under “digital assets” but does not state a coin count. The 18,712 figure comes from the company’s earlier filings (a June 8-K reported by Yahoo Finance, and the second-quarter 10-Q per finrep.ai), and Digital Today reports it was unchanged from end-June. Score: 1 out of 2. The count is known, but not from this release.

Check 2: Cost basis against fair value

The question: what did the company pay, and what is it worth now? The gap is the unrealised gain, which exists on paper only until the coins are sold. A holding bought at $35,000 and one bought at $120,000 can show the same fair value today and tell very different stories about the buyer’s timing and the tax bill that a sale would trigger.

SpaceX: the Yahoo Finance article on the June 8-K gives a cost of about $661 million, roughly $35,300 per coin, and Digital Today applies it to the September value to get an unrealised gain of $912 million. The arithmetic is right (1,573 minus 661), but the cost figure is from secondary reporting of an earlier filing, not from the Q3 release. Score: 1 out of 2.

Check 3: Where the gain lands, and how it compares with the result

The question: how much of the quarter’s profit is a mark-to-market movement in bitcoin, and is it separated clearly from operations? Strip it out before judging the business. If the line is not separated, look for a “gain on digital assets” item in other income.

SpaceX: the change in carrying value from June to September was $475 million (our subtraction), against net income of $4.40 billion, so the bitcoin movement is roughly 11% of net income if it flows through that line. But the sources disagree. Bitcoin.com says the release shows a $64 million unrealised loss on digital assets over nine months, which implies earlier quarters lost money; TechCrunch mentions “about $1 billion” of other income from the recovery of bitcoin prices, which does not match $475 million. We could not reconcile them without the filing. Score: 1 out of 2. The gain is separable in principle, but we cannot confirm its size.

Check 4: Size against everything else

The question: how large is the bitcoin relative to the company’s cash, capital spending and market value? Materiality tells you whether bitcoin can move the shares or only the footnotes. A useful test is how much of a year’s cash flow a 20% price move would erase.

SpaceX: $1.573 billion is about 3.1% of the $51.29 billion of cash and about 8.0% of the $19.59 billion spent on capital projects in the quarter (FinanceFeeds for the cash and capex figures; ratios ours). Over nine months SpaceX spent $48.07 billion on capex against $13.10 billion of operating cash flow. A 20% fall in bitcoin would cut the holding by about $315 million, roughly 1.6% of one quarter’s capex. The figure is clearly disclosed and clearly small relative to the business. Score: 2 out of 2.

Check 5: Custody and intent

The question: who holds the coins, and what does the company say it will do with them? Look for a named custodian, a statement about whether the coins are pledged as collateral, and any policy about buying or selling. A holding that is stated to be “not for sale” is different from one held for “treasury management”, and both differ from one that is silent.

SpaceX: the Yahoo Finance article says the filing does not name the custodian and that on-chain trackers see only part of the holding (it cites Arkham at about 8,280 coins), which the article attributes to omnibus third-party wallets; that explanation is the article’s, not the company’s. On intent, the only evidence we have is the unchanged count between June and September. Score: 1 out of 2.

A 6 out of 10 does not mean SpaceX is hiding anything. It means that, from the sources we could read, three of the five items rest on secondhand reporting or conflicting figures, which is exactly the situation in which you should wait for the 10-Q.

What the position is worth at different prices

Because the count is fixed at 18,712 units (assuming no change since June), the value at any price is simple arithmetic. The table below shows the holding at several bitcoin prices, against the $1.573 billion quarter-end carrying value and the $661 million reported cost.

Bitcoin priceHolding valueChange vs 30 Sep carrying valueGain over reported cost
$60,000$1,123M-450M+462M
$70,000$1,310M-263M+649M
$82,572$1,545M-28M+884M
$90,000$1,684M+111M+1,023M
$100,000$1,871M+298M+1,210M

A $10,000 move in bitcoin equals about $187 million, which is about 0.4% of the $48.07 billion spent on capex over nine months and about 4% of Q3’s $4.40 billion net income. Tesla’s 11,509 coins would move by $115 million for the same $10,000. These are descriptions of sensitivity, not forecasts.

Reading the next one: Tesla tonight

Tesla reports after the close on Wednesday 21 October. Run the same five checks on its release: does it state the coin count (Digital Today puts it at 11,509 at end-June), what is the cost basis, where does the fair-value change appear, and how does it compare with Tesla’s quarterly cash flow? Because Tesla holds bitcoin, a lot of readers will look for a bitcoin line in the results, but our earnings preview and SpaceX news piece show the same lesson: the line is real, but the business is something else. Our Guide #60 shows how to tell a business from a bitcoin fund, and Guide #63 explains how to read the ETF flow table that often accompanies these stories.

Common mistakes

  • Treating fair value as cash. The $1.573 billion is a quoted-price mark, not money in the bank; it could be higher or lower by the time it is sold.
  • Using a quarter-end value as today’s value. Bitcoin has moved from $83,556 at 30 September to about $82,572 now, so the holding is worth less than the figure on the page.
  • Assuming no news means no change. Unchanged units between two filings does not mean no trading in between; check the notes for purchases and sales.
  • Treating a combined holding as a signal. If SpaceX and Tesla merged, the 30,221 combined coins would be one holding, not new demand.

Method and sources. Fair values, units and cost are as reported by the sources linked above and have not been checked against the SpaceX 10-Q. Bitcoin prices are Coinbase UTC daily closes. Ratios, the sensitivity table and the percentage changes are our calculations from those inputs.

Method: bitcoin prices, highs, lows and closes are Coinbase Exchange candles (UTC day or UTC hour) pulled by Bitcoin Mastery at about 06:15 UTC on Wednesday 21 October 2026; the 21 October candle is still open at that time, so any closing figure quoted is the 20 October close unless stated. Index, stock, VIX, oil and yield figures are Yahoo Finance daily data (US closes of Tuesday 20 October) or the news sources cited. Other third-party figures are attributed to their source and date. The table of holding values multiplies 18,712 units by the prices shown; it assumes the count is unchanged since June.
