Metaplanet just bought its way to 43,000 Bitcoin

Tokyo-listed @Metaplanet has added 2,823 $BTC during the second quarter of 2026, bringing its total holdings to exactly 43,000 Bitcoin. The purchase was funded through a combination of credit facility borrowing and bond issuance, avoiding fresh share dilution. At current prices, the full stack is valued at roughly $2.6 billion.

The acquisition cements Metaplanet's position as the world's third-largest publicly traded corporate Bitcoin holder, trailing only Strategy and Twenty One Capital, according to data tracked by Bitcoin Treasuries. Shares of the Tokyo-listed firm (ticker 3350) closed 3.5% higher at 207 yen on the day of the announcement.

Cost Basis and the mNAV Problem

The Q2 purchase was executed at an average price of around 12.7 million yen per coin, meaningfully below the company's overall average acquisition cost of 15.3 million yen per Bitcoin across its entire stack. That gap matters: buying below the cost basis is one of the few concrete ways a corporate accumulator can improve long-term unit economics without relying on price appreciation alone. After offsetting income from its Bitcoin Income Generation business, the effective acquisition cost for the quarter fell further, to roughly 12.09 million yen per coin.

Still, the broader picture is more complicated. Metaplanet's total Bitcoin investment now stands at approximately 659 billion yen (around $4.2 billion), while holdings are valued at roughly 409 billion yen as of June 30. The company's mNAV, which compares its market value to the value of its Bitcoin holdings, recently dipped to around 0.92x, meaning the stock was trading at a discount to the underlying asset base.

CEO @gerovich has addressed the discount directly. Under a capital allocation policy established in October 2025, the company will strongly consider repurchasing common shares when mNAV falls below 1.0x, with the logic that buying back discounted shares increases Bitcoin exposure per remaining share. Gerovich cautioned, however, that any actual buyback would need to comply with Japanese insider trading rules and disclosure requirements, and his comments should not be read as confirmation that repurchases are underway or planned for a specific date.

Income Business and the Road to 210,000 BTC

Alongside the treasury update, Metaplanet disclosed Q2 results for its Bitcoin Income Generation business, which uses Bitcoin options to produce recurring revenue. The segment generated approximately 1.747 billion yen in operating revenue for the quarter, down around 41% from Q1. On a trailing 12-month basis, however, revenue from the division reached approximately 11.4 billion yen, providing a smoother picture of the business's underlying scale.

The company reported a BTC Yield of 6.6% for the quarter ended June 30, a metric that tracks growth in Bitcoin per diluted share and serves as its primary performance indicator. The current stack of 43,000 BTC puts @Metaplanet roughly a fifth of the way toward its long-term target of 210,000 Bitcoin by end-2027, equal to approximately 1% of Bitcoin's fixed supply. A nearer-term milestone of 100,000 BTC is targeted by the end of 2026, which would require the firm to acquire a further 57,000 coins in roughly six months.
