SpaceX’s IPO filing quietly revealed something the market had underestimated for years: Elon Musk’s rocket company holds 18,712 BTC on its balance sheet, worth about $1.42 billion at Bitcoin’s current price of near $75,954.
Before the S-1 drop, on-chain analysts had only publicly identified about 8,285 BTCm, meaning the real number was more than double what anyone had been tracking. Asset manager Grayscale Research now says SpaceX is on track to become the largest diversified public company holding Bitcoin upon its June 12 listing on Nasdaq.

We expect more public companies to hold $BTC over time.

Grayscale search: Here’s the central tension this article uncovers: SpaceX and MicroStrategy are both in charge of Bitcoin, but they’re doing it for entirely different reasons, using entirely different logic, and understanding that difference tells you something important about what institutional belief in crypto actually looks like, versus what it’s confused for.

SpaceX and Saylor: What Buying Bitcoin in Business Really Means in Plain English
Think of it as two very different types of owners. A person buys a house almost entirely as a financial gamble, they expect the property to appreciate, and they have taken out loans to buy other houses on the same thesis.
The other person buys a house to live in, but also keeps some of their savings in gold to protect against inflation. Both have the same asset. Their risk profiles couldn’t be more different.
This is basically the comparison between MicroStrategy and SpaceX. MicroStrategy, led by Michael Saylor, holds 843,738 BTC, a stack more than 45 times larger than SpaceX’s, and generates limited operating revenue outside of this position.
The company used convertible notes (bonds that can be converted into company stock) and preferred stock offerings to raise capital specifically to purchase more Bitcoin. Saylor’s playbook treats MicroStrategy essentially as a leveraged Bitcoin proxy for stock investors who want exposure to BTC through a stock account.
SpaceX’s Bitcoin holdings tell a different story. The company built its position at an average cost of around $35,000 per BTC, accumulating the majority during the 2021 bull market for a total cost of $661 million.
This position generated a paper gain of $955 million in 2024, then shifted to an unrealized loss of $112 million in 2025, real swings that yielded profits even without selling a single coin. But aside from SpaceX’s revenue from rockets, its Starlink satellite network and government space contracts, Bitcoin is a small component, accounting for just 0.1% of the company’s $1.75 trillion IPO valuation target.
Musk versus Saylor: two whales, two very different playbooks
Whale watching in crypto means following what the largest holders are doing with their Bitcoin, not because you should blindly copy them, but because their behavior says something about long-term conviction.
Both SpaceX and MicroStrategy are considered institutional crypto-whales by any measure. But what their accumulation signals is not the same thing.
MicroStrategy’s position is a statement. Saylor has made it clear that the company should never be a net seller of Bitcoin, and that each new bond transaction or stock offering is designed to add more BTC to the treasury.
This is a high-conviction, high-leverage bet that Bitcoin will outperform everything else over a long-term horizon. The risk is just as great: if the price of Bitcoin collapses, MicroStrategy’s equity collapses with it. What this means for small investors is worth understanding before drawing conclusions about the strategy.
SpaceX’s position is a hedge. Grayscale divides Bitcoin-holding companies into two camps: pure-play digital asset treasuries like MicroStrategy and diversified companies that hold Bitcoin alongside real operating revenue, like Tesla, Coinbase, and Block. SpaceX is firmly in the second camp.
Its Bitcoin reserve protects against the erosion of fiat currency without betting the company on crypto markets. Business Insider analysts noted that the S-1 shows that SpaceX has held up through multiple market cycles, a show of conviction, but not the same existential commitment as Saylor.
The overall picture confirms that both approaches are becoming more widespread. At least 100 publicly traded companies have adopted some form of Bitcoin cash policy. The companies’ combined Bitcoin holdings now total around 1.24 million BTC, or more than 5% of the total supply. Institutional adoption of crypto is no longer a fringe experience.
