Metaplanet Crosses 10,000 BTC Threshold, Overtakes Coinbase
Japanese investment firm Metaplanet has increased its Bitcoin holdings to 10,000 BTC after acquiring an additional 1,112 BTC for 16.88 billion yen, approximately $117 million. The purchase pushes Metaplanet ahead of Coinbase, which holds 9,267 BTC, and elevates the Tokyo-listed company to the position of the seventh-largest publicly traded company with a Bitcoin treasury.
The acquisition marks a significant milestone for a firm that has rapidly transformed itself into one of the most aggressive corporate Bitcoin accumulators in Asia. Metaplanet’s total stack now stands at 10,000 BTC, with an average cost basis across the full holding of approximately 13.9 million yen per BTC, roughly $96,400 per coin. That figure places the firm’s entry point well below current market levels for Bitcoin, suggesting substantial unrealised gains on the position.
The move to surpass Coinbase is particularly notable. Coinbase is one of the largest and most recognised cryptocurrency exchanges globally, and its Bitcoin holdings reflect operational reserves alongside treasury allocation. Metaplanet, by contrast, is an investment firm that has pivoted toward Bitcoin as its primary strategic asset. Overtaking Coinbase on the leaderboard of public company Bitcoin holders signals a shift in the competitive dynamics among listed firms pursuing Bitcoin treasury strategies.
The ranking of public companies by Bitcoin treasury size has become a closely watched metric in the crypto market. Firms such as Microstrategy have long dominated the space, but the entry of Asian companies like Metaplanet into the upper tiers reflects a broadening of corporate adoption beyond North America.

Zero-Interest Bonds Fund Aggressive Accumulation Strategy
Metaplanet has not been subtle about its intentions. The firm recently announced a plan to issue $210 million in zero-interest bonds to raise additional capital specifically for Bitcoin purchases. The bond issuance underscores the extent to which the company is willing to leverage its balance sheet to acquire more of the cryptocurrency.
Zero-interest bonds are an unusual instrument in the context of corporate treasury management. By issuing debt that carries no interest obligation, Metaplanet effectively raises capital without the ongoing cost of coupon payments, provided the principal is repaid at maturity. The strategy relies on the assumption that Bitcoin will appreciate sufficiently over the bond’s term to cover repayment and generate a return for shareholders. It is a high-conviction approach that treats Bitcoin not as a speculative side bet but as the core asset underpinning the firm’s financial strategy.
The company has stated that it aims to reach 210,000 BTC by the end of 2027. That target would require the acquisition of an additional 200,000 BTC over the next 18 months. To put that figure in perspective, 200,000 BTC represents a substantial fraction of the total Bitcoin supply. The scale of the ambition is extraordinary, and whether the firm can execute on it remains an open question that the market will be watching closely.
The use of debt to fund Bitcoin purchases is not without precedent. Microstrategy has used convertible notes and other debt instruments to finance its Bitcoin acquisitions, and the approach has drawn both praise and criticism from market analysts. Supporters argue that borrowing to buy Bitcoin at favourable rates can generate significant returns if the asset appreciates. Critics warn that leverage introduces downside risk, particularly if Bitcoin experiences a prolonged bear market that compresses the firm’s ability to service or refinance its obligations.
Metaplanet’s zero-interest bond structure differs from the convertible note approach used by Microstrategy, but the underlying logic is similar. The firm is betting that Bitcoin’s long-term appreciation will outweigh the cost of carrying debt, and in this case, the cost is structurally minimised by the zero-interest feature. The trade-off is that investors in the bonds are accepting no yield in exchange for what is presumably an expectation of repayment backed by the firm’s Bitcoin-backed balance sheet.
Stock Surges as Tokyo Market Rewards Bitcoin Bet
The market response to Metaplanet’s latest purchase was emphatic. The firm’s stock rose more than 22% on the Tokyo Stock Exchange, briefly hitting 1,860 yen during trading. The rally extends a remarkable run for the company’s shares, which have climbed over 417% year-to-date.
That kind of share price performance is rare for a Japanese investment firm and reflects the degree to which the market has bought into Metaplanet’s Bitcoin-centric strategy. Investors are clearly pricing in the potential upside of the firm’s accumulation plan, as well as the unrealised gains on its existing 10,000 BTC position. The stock’s movement also suggests that retail and institutional investors in Japan are increasingly comfortable with the idea of a public company serving as a Bitcoin proxy.
The Tokyo Stock Exchange has not historically been a hub for crypto-adjacent equities, but Metaplanet’s performance may change that perception. The firm’s rise could encourage other Japanese companies to consider Bitcoin treasury allocations, particularly if the share price appreciation continues to attract attention. Japan’s regulatory environment for digital assets is relatively well-defined compared with some jurisdictions, which may provide a degree of comfort for companies considering similar strategies.
The year-to-date gain of over 417% also raises questions about valuation. Metaplanet’s stock is now trading at a significant premium to the value of its Bitcoin holdings, which means investors are paying for the expectation of future accumulation rather than the current stack alone. If the firm fails to meet its ambitious 210,000 BTC target, or if Bitcoin’s price retreats materially, that premium could compress rapidly. The stock’s volatility is likely to remain elevated as a result.
The Corporate Bitcoin Arms Race Intensifies
Metaplanet’s ascent past Coinbase on the Bitcoin treasury leaderboard highlights an ongoing competitive dynamic among publicly listed companies. Treasury size has become a visible signal of conviction in the asset, and firms are increasingly measured not just by the fact that they hold Bitcoin but by how much they hold relative to peers.
The competition is not purely symbolic. Larger Bitcoin holdings can attract different classes of investors, including those who seek exposure to Bitcoin through regulated equity markets rather than direct cryptocurrency purchases. For firms like Metaplanet, a growing treasury can also serve as a marketing tool, drawing media coverage and investor attention that supports the share price and lowers the cost of future capital raises.
The broader implication for the Bitcoin market is that corporate demand remains a meaningful source of buying pressure. While institutional inflows through exchange-traded funds have dominated headlines, the activity of public companies like Metaplanet represents a distinct and persistent source of demand. These firms tend to hold rather than trade, which removes Bitcoin from active circulation and can contribute to supply scarcity.
Metaplanet’s plan to acquire 200,000 additional BTC over the next 18 months, if even partially executed, would represent a significant demand shock. The question is whether the firm can raise the necessary capital through bond issuances and other means without encountering resistance from investors or regulators. The zero-interest bond structure may appeal to a specific subset of investors, but the firm will need to demonstrate consistent execution to maintain confidence.
The regulatory landscape in Japan will also play a role. While the country has established frameworks for cryptocurrency trading and custody, the use of debt instruments to fund Bitcoin purchases by a public company sits at the intersection of securities regulation and digital asset policy. Regulators may take a closer look at the practice if it becomes more widespread, particularly if market conditions deteriorate and investors in such bonds face losses.
For now, Metaplanet’s strategy is working. The stock is soaring, the Bitcoin stack is growing, and the firm has cemented its place among the top public company Bitcoin holders. Whether the momentum can be sustained over the 18-month horizon required to reach the 210,000 BTC target is another matter entirely.
Closing Analysis
Metaplanet’s latest purchase and its overtaking of Coinbase mark a meaningful moment in the corporate Bitcoin adoption narrative. The firm is operating at the aggressive end of the spectrum, using zero-interest debt to fund acquisitions that would be considered audacious for a company of any size. The 417% year-to-date stock gain shows that the market is rewarding that aggression, at least for now. The real test will come in the form of execution risk. Acquiring 200,000 BTC in 18 months is a target that demands enormous capital deployment and sustained investor confidence. If Bitcoin’s price falters or bond market appetite wanes, the strategy could face significant headwinds. The corporate Bitcoin arms race is far from over, and Metaplanet has just made clear it intends to be near the front.
