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

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

Here is the central tension this article unpacks: SpaceX and MicroStrategy are both loading up on Bitcoin, but they are doing it for entirely different reasons, using entirely different logic, and understanding that difference tells you something important about what institutional crypto conviction actually looks like, versus what it gets mistaken for.

SpaceX and Saylor: What Corporate Bitcoin Buying Actually Means in Plain English
Think of it like two very different kinds of homeowners. One person buys a house almost entirely as a financial bet, they expect the property to appreciate and they have taken out loans to buy more houses on the same thesis.
The other person buys a house to live in, but also keeps a chunk of savings in gold as a hedge against inflation. Both own the same asset. Their risk profiles could not be more different.
That is essentially the MicroStrategy versus SpaceX comparison. 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 that position.
The company has used convertible notes (bonds that can convert into company stock) and preferred share offerings to raise capital specifically to buy more Bitcoin. Saylor’s playbook treats MicroStrategy essentially as a leveraged Bitcoin proxy for equity investors who want BTC exposure through a stock market account.
SpaceX’s Bitcoin holdings tell a different story. The company built its position at an average cost of roughly $35,000 per BTC, accumulating most of it during the 2021 bull market at a total cost of $661 million.
That position generated a $955 million paper gain in 2024, then swung to a $112 million unrealized loss in 2025, real swings that move reported earnings even without selling a single coin. But beside SpaceX’s revenue from rockets, its Starlink satellite network, and government space contracts, Bitcoin is a small line item, representing just 0.1% of the company’s $1.75 trillion IPO valuation target.
Musk vs. Saylor: Two Whales, Two Very Different Playbooks
Whale watching in crypto means tracking what the largest holders are doing with their Bitcoin, not because you should copy them blindly, but because their behavior reveals something about long-term conviction.
Both SpaceX and MicroStrategy qualify as institutional crypto whales by any measure. But what their accumulation signals is not the same thing.
MicroStrategy’s position is a declaration. Saylor has been explicit that the company should never be a net seller of Bitcoin, and every new bond deal or share offering is designed to add more BTC to the treasury.
It is a high-conviction, high-leverage bet that Bitcoin outperforms everything else over a long time horizon. The risk is equally large: if Bitcoin price collapses, MicroStrategy’s equity collapses with it. What that means for smaller investors is worth understanding before drawing any conclusions about strategy.
SpaceX’s position is a hedge. Grayscale separates corporate Bitcoin holders into two camps, pure-play digital asset treasuries like MicroStrategy, and diversified businesses that hold Bitcoin alongside real operating revenue, like Tesla, Coinbase, and Block. SpaceX sits firmly in the second camp.
Its Bitcoin reserve cushions against fiat currency erosion without betting the company on crypto markets. Analysts at Business Insider noted the S-1 shows SpaceX has held through multiple market cycles, evidence of conviction, but not the same existential commitment Saylor has made.
The broader picture confirms both approaches are spreading. At least 100 publicly traded firms have adopted some form of Bitcoin treasury policy. Combined corporate Bitcoin holdings now total around 1.24 million BTC, more than 5% of total supply. Institutional crypto adoption is no longer a fringe experiment.
