Companies adding Bitcoin to their balance sheets have become one of the most compelling narratives in public markets. Although investors have multiple ways to gain direct Bitcoin exposure—such as ETFs, spot Bitcoin, wrapped Bitcoin, and futures contracts—many still choose to buy shares of Bitcoin reserve companies whose stock trades at a significant premium to their net asset value (NAV) in Bitcoin.
This premium refers to the difference between a company's share price and the value of its Bitcoin holdings per share. For example, if a company holds $100 million worth of Bitcoin and has 10 million shares outstanding, its Bitcoin NAV per share would be $10. If the share price is $17.50, the premium would be 75%. In this context, mNAV (multiple to NAV) reflects how many times the share price exceeds the Bitcoin NAV, and the premium rate is the percentage above that value.
Many investors wonder: Why can these companies be valued so much higher than the underlying Bitcoin assets themselves?
Leverage Effect and Capital Access
The most crucial reason Bitcoin reserve company stocks trade at a premium is their ability to use public capital markets for leverage. These firms can raise capital by issuing debt and equity to acquire more Bitcoin. Essentially, they act as high-beta proxies for Bitcoin, amplifying its exposure to market fluctuations.
One of the most common and effective strategies is the "at-the-market" (ATM) equity offering program. This mechanism allows a company to issue additional shares gradually at prevailing market prices with minimal disruption. When the stock trades at a premium to Bitcoin NAV, every dollar raised through an ATM offering can buy more Bitcoin than the dilution caused by the new shares. This creates a "value-accretive cycle" for Bitcoin holdings per share, continuously increasing Bitcoin exposure.
MicroStrategy is the prime example of this strategy. Since 2020, the company has raised billions through convertible bond issuances and secondary equity offerings. As of June 30, MicroStrategy held 597,325 Bitcoin (approximately 2.84% of the circulating supply).
Such financing tools are only available to public companies, enabling them to accumulate Bitcoin consistently. This not only amplifies Bitcoin exposure but also reinforces a compounding narrative effect—every successful capital raise and Bitcoin purchase strengthens investor confidence in the model. Thus, investors buying MSTR stock are not just buying Bitcoin; they are buying "the ability to keep acquiring more Bitcoin in the future."
How Large Is the Premium?
The table below compares the premiums of several Bitcoin reserve companies. MicroStrategy holds the most Bitcoin of any public company and is the best-known representative in this space. Metaplanet is among the most aggressive accumulators (its transparency advantages are detailed later). Semler Scientific adopted this trend early, beginning its Bitcoin purchases last year. France’s The Blockchain Group illustrates how the trend is spreading beyond the U.S. to global markets.
Although MicroStrategy’s premium is relatively moderate (around 75%), smaller companies like The Blockchain Group (217%) and Metaplanet (384%) show significantly higher premiums. These valuations suggest that the market is pricing not just Bitcoin’s growth potential but also the ability to access capital markets, speculative upside, and narrative value.
Bitcoin Yield: A Key Metric Behind the Premium
A core metric driving these stock premiums is "Bitcoin yield." This measures the growth in Bitcoin holdings per share over a specific period, reflecting how efficiently a company uses its fundraising ability to accumulate Bitcoin without causing excessive equity dilution. Metaplanet stands out for its transparency, providing a real-time Bitcoin data dashboard on its website that updates Bitcoin holdings, Bitcoin per share, and Bitcoin yield dynamically.
Metaplanet also publicly shares proof of reserves, a practice not yet adopted by some peers. For example, MicroStrategy has not implemented any on-chain verification mechanism to prove its Bitcoin holdings. At the "Bitcoin 2025" conference in Las Vegas, Executive Chairman Michael Saylor explicitly opposed public proof of reserves, calling it a "bad idea" due to security risks. He argued that it "reduces security for issuers, custodians, exchanges, and investors."
This view is controversial. On-chain proof of reserves only requires sharing public keys or addresses, not private keys or signing data. Since Bitcoin’s security model is based on the principle that public keys can be safely shared, disclosing wallet addresses does not endanger assets (this is a fundamental feature of the Bitcoin network). On-chain proof of reserves offers investors a direct way to verify the authenticity of a company’s Bitcoin holdings.
What If the Premium Disappears?
So far, high valuations for Bitcoin reserve companies have existed in a bull market characterized by rising Bitcoin prices and high retail enthusiasm. No Bitcoin reserve company has seen its stock trade consistently below NAV for an extended period. This business model relies on the premium’s persistence.
As noted by VanEck analyst Matthew Sigel, "When the share price falls to NAV, equity dilution is no longer strategic—it becomes value extraction." This statement highlights the model’s core vulnerability. ATM equity offerings—the capital engine for these companies—rely fundamentally on share price premiums. When the stock trades above Bitcoin value per share, equity fundraising can increase Bitcoin holdings per share. But if the share price falls near NAV, equity dilution would weaken, not enhance, shareholders’ Bitcoin exposure.
This model depends on a self-reinforcing cycle:
- Share price premium enables fundraising capability.
- Fundraising is used to acquire more Bitcoin.
- Bitcoin accumulation strengthens the company’s narrative.
- Narrative value sustains the share price premium.
If the premium disappears, the cycle breaks: funding costs rise, Bitcoin accumulation slows, and narrative value weakens. Currently, Bitcoin reserve companies still benefit from capital market access and investor enthusiasm. Still, their future will depend on financial discipline, transparency, and the ability to "increase Bitcoin per share" rather than simply accumulating more Bitcoin. The optionality value that makes these stocks attractive in a bull market could quickly become a liability in a bear market.
Frequently Asked Questions
What is a Bitcoin reserve company?
A Bitcoin reserve company is a publicly traded firm that holds a significant amount of Bitcoin on its balance sheet as a primary treasury asset. These companies often use capital market tools to raise funds and increase their Bitcoin exposure over time.
Why do these companies trade at a premium to their Bitcoin NAV?
The premium reflects market expectations beyond the value of the Bitcoin itself, including the company’s ability to raise capital and acquire more Bitcoin, its strategic positioning, and investor sentiment toward Bitcoin’s future appreciation.
How does proof of reserves work?
Proof of reserves involves using on-chain data to verify that a company holds the Bitcoin it claims. By publishing wallet addresses or cryptographic proofs, the company allows anyone to audit its holdings transparently, increasing trust and reducing counterparty risk.
What risks are associated with investing in these companies?
Key risks include Bitcoin price volatility, dilution from equity offerings, loss of premium valuation, regulatory changes, and operational challenges related to Bitcoin custody and corporate strategy execution.
Can the premium disappear?
Yes. If investor sentiment sours or Bitcoin’s price declines sharply, the premium could erode. This would break the cycle of capital raising and accumulation, potentially leading to dilution and reduced shareholder value.
How can investors track these companies?
Investors can monitor corporate filings, earnings reports, and specialized dashboards that provide real-time data on Bitcoin holdings, NAV calculations, and capital raising activities. For deeper insights, explore more strategies and analytical resources available online.
