Twenty One Capital holds 43,514 Bitcoin, yet its stock market value sits well below the value of those holdings. Its August 11 quarterly filing shows how that discount forms and why mNAV can vary sharply by method.
The company ranks as the second-largest listed Bitcoin holder after Strategy. Tether backed its entry into the Bitcoin treasury sector.
Bitcoin treasury companies hold Bitcoin as a principal balance-sheet asset. Unlike a spot Bitcoin ETF, their shares do not directly represent ownership of the Bitcoin held by the company. Instead, a listed company also carries debt, operating costs, and corporate obligations. Its share price moves with market demand for the stock rather than only with Bitcoin’s market value.
That structure creates either a premium or a discount to asset value. Twenty One Capital currently trades at a wide discount compared with the value of its Bitcoin holdings.
The key measure is mNAV, or market net asset value. It divides a company’s market capitalisation by the market value of its Bitcoin holdings. An mNAV of 1.0 means the share trades at parity with the Bitcoin value. A reading above 1.0 signals a premium, while a figure below 1.0 signals a discount.
At an mNAV of 0.6, investors effectively pay 60 cents for each dollar of Bitcoin on the balance sheet. Depending on the method, Twenty One Capital’s discount ranges from 43% to zero. Does a deep mNAV discount make the share cheaper than Bitcoin, or does the company structure explain the gap?

Twenty One Capital reported 43,514 Bitcoin as of June 30, 2026, one fewer than at the start of the year. It bought no Bitcoin during the half-year. The filing listed a $2.55 billion carrying value, equal to about $58,600 per Bitcoin. Acquisition cost stood at $3.69 billion, or roughly $84,900 per Bitcoin. That left the holding about $1.14 billion below purchase cost.
The company posted a $413.5 million quarterly loss and a $1.27 billion half-year loss. The quarterly figure included a $401.5 million change in the fair value of digital assets. Operating losses contributed about $10.7 million, while interest expense added another $1.3 million. The company also reported $484.5 million in convertible bonds against $486.1 million in total liabilities.
ASU 2023-08 requires crypto holdings to be measured at market value at each reporting date. Changes in Bitcoin’s value then flow through the income statement, even when the company sells no Bitcoin. As a result, a falling Bitcoin price can create a large reported loss without a matching disposal of the asset. Twenty One Capital issued no preference shares during the period.
Twenty One Capital’s filing shows that its 43,514 Bitcoin holdings sit alongside debt, operating costs and large fair value swings. The mNAV discount therefore reflects more than Bitcoin’s market price alone. Investors comparing the stock with direct Bitcoin exposure need to examine the chosen mNAV method and company balance sheet.
