Metaplanet crosses 10,000 BTC threshold and overtakes Coinbase
Japanese investment firm Metaplanet has purchased 1,112 Bitcoin for 16.88 billion yen, roughly $117 million, pushing its total holdings to 10,000 BTC. The acquisition, announced Monday, makes Metaplanet’s Bitcoin treasury larger than that of Coinbase, the major United States cryptocurrency exchange, which held 9,267 BTC according to data from Bitbo cited in the report.
The milestone is significant for several reasons. Coinbase is not a peripheral player. It is one of the most prominent publicly traded companies in the digital asset sector, and its own Bitcoin holdings reflect its position as a primary infrastructure provider for the cryptocurrency market. That a Japanese investment firm, whose core business historically sat outside cryptocurrency, has now surpassed Coinbase in Bitcoin holdings underscores how aggressively corporate treasury strategy is shifting.
Metaplanet’s average cost basis across its 10,000 BTC now stands at approximately 13.9 million yen per coin, or about $96,400. That figure provides a useful reference point for understanding the firm’s exposure. With Bitcoin trading above that level in recent sessions, the company’s treasury position is effectively in profit on paper. More importantly, the average cost basis signals that Metaplanet has been buying consistently across different price environments rather than attempting to time the market. It has been accumulating.
The purchase of 1,112 BTC for approximately $117 million implies an average acquisition price of roughly $105,200 per coin for this specific tranche. That is above the blended average cost basis of $96,400, indicating that the most recent purchase was executed at a higher price point than earlier acquisitions. This is consistent with a strategy of steady accumulation regardless of short-term price movements, a approach that mirrors the playbook made famous by MicroStrategy in the United States.

Zero-coupon bonds and the road to 210,000 BTC
The same announcement revealed that Metaplanet’s board has approved the issuance of $210 million in no-interest bonds. The proceeds are intended to fund further Bitcoin purchases. Zero-coupon bonds, which pay no periodic interest and are typically issued at a discount to their face value, allow the company to raise capital without the ongoing burden of coupon payments. The structure is notable because it reflects a deliberate choice to prioritise capital deployment into Bitcoin over traditional debt-service obligations.
This is not a modest incremental step. Metaplanet has set a target of holding 210,000 BTC by the end of 2027. With current holdings at 10,000 BTC, the firm still needs to acquire approximately 200,000 BTC over the next 18 months if it intends to stay on schedule. That is a staggering volume of Bitcoin. To put it in perspective, 200,000 BTC represents roughly 1% of Bitcoin’s total fixed supply of 21 million coins. It also represents a meaningful fraction of the liquid Bitcoin available on exchanges at any given time.
The target of 210,000 BTC is clearly a nod to Bitcoin’s hard cap of 21 million coins. The number itself is a signal to the market that Metaplanet sees Bitcoin not as a speculative position but as a long-duration store of value. Whether the firm can actually execute on this target within the stated timeframe is an open question. Acquiring 200,000 BTC would require tens of billions of dollars in capital. The $210 million bond issuance, while substantial, would only fund a fraction of that ambition at current prices.
This raises important questions about how Metaplanet plans to finance the remaining purchases. The company could issue additional debt, raise equity capital, or use a combination of financial instruments. It could also generate operating cash flow from its existing businesses to fund acquisitions. The market will be watching closely to see whether subsequent capital raises match the scale of the stated ambition.
The use of no-interest bonds also carries inherent risks. If Bitcoin’s price declines significantly from current levels, the company’s treasury assets would lose value while its debt obligations would remain fixed. This is the same structural risk that has drawn scrutiny to other Bitcoin-heavy corporate treasuries. The difference is one of degree. Metaplanet’s target of 210,000 BTC, if pursued aggressively through leverage, would create one of the most concentrated corporate Bitcoin positions in the world.
Tokyo market rewards the strategy with 22% rally
Metaplanet’s shares rallied more than 22% on the Tokyo Stock Exchange on Monday, reaching as high as 1,860 yen. The move was a clear endorsement from equity investors. It also demonstrated that the market is interpreting Metaplanet’s Bitcoin strategy as a growth catalyst rather than a conservative treasury-management decision.
There is an important distinction here. Traditional corporate treasury management emphasises capital preservation and liquidity. Companies typically hold cash, short-term government securities, or high-grade corporate bonds to ensure they can meet obligations and fund operations. Metaplanet is doing something fundamentally different. It is converting its treasury into a volatile digital asset and financing that conversion through debt issuance. The equity market’s enthusiastic response suggests that investors view this not as reckless risk-taking but as a value-creating strategy.
The 22% rally also reflects the leverage that Bitcoin exposure provides to Metaplanet’s equity. When Bitcoin’s price rises, the value of Metaplanet’s holdings increases, which in turn boosts the net asset value of the company. Because the company has funded some of its purchases with debt, the percentage gain in equity value can exceed the percentage gain in Bitcoin’s price. This is the same dynamic that has driven MicroStrategy’s stock performance in the United States, where the company’s shares have often moved with amplified correlation to Bitcoin’s price.
However, this leverage works in both directions. A sharp decline in Bitcoin’s price would reduce the value of Metaplanet’s holdings while leaving its debt obligations unchanged. The equity market’s current enthusiasm assumes that Bitcoin’s price will remain stable or continue to appreciate. If that assumption proves wrong, the same leverage that amplifies gains on the way up will amplify losses on the way down.
The Tokyo Stock Exchange’s reaction also matters for the broader Japanese market. Japan has historically maintained a cautious regulatory posture toward cryptocurrencies, with stringent exchange licensing requirements and accounting rules. The fact that a publicly listed Japanese firm is now one of the largest corporate Bitcoin holders in the world signals a shift in sentiment within one of Asia’s major financial centres. Other Japanese firms may take note of the market’s positive response and consider similar strategies.
Corporate Bitcoin competition intensifies
Metaplanet’s overtaking of Coinbase in Bitcoin holdings highlights an intensifying competition among public companies for Bitcoin exposure. This is not a competition in the traditional sense. Companies are not bidding against each other for specific assets. But they are competing for investor attention, capital, and the narrative of being the most committed corporate Bitcoin holder.
Coinbase’s position is particularly instructive. As a cryptocurrency exchange, Coinbase sits at the centre of the digital asset ecosystem. It facilitates trading, custody, and institutional access to Bitcoin and other cryptocurrencies. Yet its own Bitcoin treasury, at 9,267 BTC, is now smaller than that of a Japanese investment firm that only recently began accumulating. This suggests that Coinbase has chosen to hold a relatively conservative Bitcoin position on its balance sheet, perhaps because its business model already provides extensive exposure to cryptocurrency markets through its operating revenue.
Metaplanet, by contrast, has no such operating exposure. Its Bitcoin holdings are a deliberate treasury strategy aimed at gaining exposure to the asset’s price appreciation. The fact that this strategy has now produced a larger Bitcoin position than Coinbase’s is a data point that will not be lost on other corporate treasurers.
The competitive dynamic also extends beyond Metaplanet and Coinbase. MicroStrategy remains the largest public corporate holder of Bitcoin, with holdings that dwarf those of most other firms. Other companies, including several in the technology and financial services sectors, have added Bitcoin to their balance sheets in smaller amounts. Metaplanet’s aggressive target of 210,000 BTC, if achieved, would place it in a category that few if any other public companies could match.
This corporate accumulation trend has implications for Bitcoin’s market structure. As more public companies hold Bitcoin on their balance sheets, a larger portion of the total supply becomes effectively illiquid. Companies tend to hold their Bitcoin for extended periods, unlike traders who buy and sell based on short-term price movements. This reduction in liquid supply can contribute to price appreciation, particularly when demand from retail and institutional investors remains steady or grows.
What this means for the broader market
Metaplanet’s latest purchase and its stated ambition to reach 210,000 BTC by the end of 2027 represent one of the most aggressive corporate Bitcoin accumulation strategies currently in motion. The firm has moved from 10,000 BTC to a target that would place it among the largest non-governmental Bitcoin holders in the world. The equity market has rewarded the strategy with a sharp rally. The bond market is funding it with zero-coupon debt.
The implications are twofold. First, Metaplanet’s actions demonstrate that corporate Bitcoin adoption is not confined to a single jurisdiction or a single type of company. The trend has spread from United States technology firms to Japanese investment companies, and it may continue to spread further. Second, the scale of Metaplanet’s target, if pursued seriously, will require enormous capital deployment. That capital will come from debt and equity markets, which means traditional investors are effectively funding Bitcoin purchases through their allocations to Metaplanet’s securities.
The risk is concentrated and transparent. Bitcoin’s price could fall. The bonds will still need to be repaid. The equity could decline sharply. But for now, the market is signalling that it believes the strategy will create value. Whether that belief is justified will depend on Bitcoin’s price trajectory over the coming years and Metaplanet’s ability to execute its accumulation plan without encountering financing constraints. The next 18 months will be telling.
