Metaplanet crosses 10,000 BTC threshold, surpassing Coinbase
Japanese investment firm Metaplanet has become one of the largest corporate Bitcoin holders in the world after a fresh acquisition pushed its treasury to 10,000 BTC, overtaking Coinbase’s known holdings of 9,267 BTC.
The Tokyo-listed company announced it purchased 1,112 BTC for 16.88 billion yen, roughly $117 million at current exchange rates. The buy brings Metaplanet’s total Bitcoin holdings to exactly 10,000 BTC and sets its average purchase price at approximately 13.9 million yen per bitcoin, equivalent to about $96,400.
The speed of the ascent is striking. Just two weeks before this latest purchase, Metaplanet had reached the status of the eighth-largest corporate Bitcoin holder. This additional acquisition has now moved it further up the rankings, past Coinbase, which is itself one of the most recognised names in the cryptocurrency industry. The symbolism is hard to ignore: a traditional Japanese investment firm now holds more Bitcoin on its balance sheet than a company whose core business is operating one of the largest crypto exchanges in the world.
Metaplanet’s trajectory has been defined by aggressive, publicly disclosed accumulation rather than quiet position-building. Each purchase has been announced with specific figures, giving investors and market observers a clear window into the firm’s strategy and cost basis. The average price of roughly $96,400 suggests the firm has been buying across a range of market levels, not simply chasing a single entry point.

No-interest bonds and the capital markets playbook
On the same day it disclosed the 1,112 BTC purchase, Metaplanet announced that its board had approved the issuance of $210 million in no-interest bonds. The stated purpose is to raise additional capital for further Bitcoin acquisitions.
The use of no-interest bonds is a notable structural choice. Traditional corporate debt instruments carry coupon payments that eat into cash flow. By issuing bonds that do not accrue interest, Metaplanet is effectively raising capital at no financing cost, assuming the bonds are structured in a way that compensates holders through conversion or other mechanisms. This allows the firm to direct the full proceeds toward Bitcoin purchases without the drag of periodic interest obligations.
This approach underscores a broader trend among corporate Bitcoin adopters: the use of capital markets instruments to fund treasury allocations. Rather than relying solely on operating cash flow or existing reserves, companies are turning to debt issuance, equity raises, and convertible structures to accelerate accumulation. The playbook was popularised by MicroStrategy in the United States, and Metaplanet appears to be applying a similar model in the Japanese market.
The $210 million bond programme, if fully deployed at current prices, would allow Metaplanet to acquire roughly 2,100 additional BTC. That would bring its holdings to approximately 12,100 BTC, closing the gap with the next tier of corporate holders and potentially moving it into the top five globally.
What makes this strategy viable is the market’s apparent willingness to fund it. The bond approval came alongside the purchase announcement, and the stock responded sharply. Investors are not merely tolerating the Bitcoin strategy; they appear to be actively rewarding it with both equity appreciation and debt participation.
The 210,000 BTC target and what it means for supply
Metaplanet’s longer-term ambition dwarfs its current holdings. The firm has set a target of holding 210,000 BTC by the end of 2027. With 10,000 BTC already on the balance sheet, that goal requires acquiring another 200,000 BTC over roughly the next 18 months.
The scale of that target is extraordinary. To put it in perspective, 210,000 BTC represents approximately 1% of Bitcoin’s total supply of 21 million coins. At a price of $96,400 per BTC, the remaining 200,000 BTC would cost roughly $19.3 billion. That is a staggering sum for a single corporate buyer, and it raises serious questions about how the firm intends to finance such an aggressive accumulation schedule.
The no-interest bond programme provides a partial answer, but $210 million in bonds covers only a fraction of the total capital required. Metaplanet would need to issue additional debt, raise equity, generate substantial operating revenue, or combine all three to reach the 210,000 BTC target. The firm has not yet detailed the full financing plan beyond the current bond issuance.
From a market structure perspective, a sustained corporate buyer of this magnitude could have a meaningful impact on available Bitcoin supply. Bitcoin’s liquid supply is already constrained by long-term holders and the reduction in issuance that follows each halving event. The most recent halving in April 2024 cut block rewards from 6.25 BTC to 3.125 BTC, reducing the daily supply of newly mined coins to roughly 450 BTC. A buyer targeting 200,000 BTC over 18 months would need to absorb roughly 365 BTC per day on average, which is a significant portion of the daily issuance.
Of course, Metaplanet will not be buying newly mined coins exclusively. It will acquire from existing holders, exchanges, and over-the-counter desks. But the aggregate demand pressure from a single corporate entity committing to this level of accumulation adds a structural bid to the market that cannot be ignored.
Market reaction and the corporate treasury trend
Metaplanet’s stock, listed on the Tokyo Stock Exchange under the ticker 3350T, rose over 22% on the Monday following the announcement, briefly reaching 1,860 yen. The sharp single-day move suggests that investors viewed the expanded Bitcoin strategy as a positive catalyst for the company’s valuation rather than a speculative risk.
The equity response is consistent with the pattern observed in other corporate Bitcoin holders. When companies announce material Bitcoin acquisitions, their share prices often react positively, particularly when the market is in a bullish phase for digital assets. The logic is straightforward: if Bitcoin appreciates, the company’s treasury gains in value, and the equity becomes a leveraged proxy for Bitcoin exposure.
This dynamic has been central to the corporate Bitcoin treasury thesis. Firms that hold large Bitcoin positions effectively offer investors indirect exposure to the asset through a traditional equity wrapper. For investors who cannot or do not wish to hold Bitcoin directly, shares in a publicly listed Bitcoin-holding company provide a regulated, custody-simplified alternative.
Metaplanet’s overtaking of Coinbase is symbolically important for another reason. Coinbase is not merely a crypto company; it is one of the largest custodians and trading venues for Bitcoin in the world. The fact that a traditional investment firm now holds more Bitcoin on its own balance sheet than Coinbase holds in its treasury highlights the distinction between operational Bitcoin holdings and corporate treasury allocations. Coinbase’s business involves holding Bitcoin on behalf of customers, but its own treasury allocation is smaller than Metaplanet’s.
The broader implication is that corporate Bitcoin treasury adoption is still expanding. The trend that began with a handful of early adopters has now spread to firms across multiple jurisdictions, including Japan, and is being financed through increasingly sophisticated capital markets instruments. The combination of no-interest bonds, public equity markets, and a clear accumulation target represents a maturation of the corporate Bitcoin treasury model.
Closing analysis
Metaplanet’s move to 10,000 BTC and its stated target of 210,000 BTC by the end of 2027 mark a significant escalation in corporate Bitcoin adoption. The firm has demonstrated that public companies can use capital markets to build large crypto positions quickly, and the positive equity response suggests that investors are receptive to the strategy.
The key question going forward is execution. Financing 200,000 BTC of additional purchases requires capital on a scale that goes well beyond the current $210 million bond programme. Whether Metaplanet can sustain this pace of accumulation depends on its ability to continue raising funds at favourable terms, and on Bitcoin’s price trajectory over the next 18 months. If Bitcoin appreciates significantly, the firm’s existing holdings gain value, potentially making additional capital raises easier. If the price declines, the cost of reaching the target rises in fiat terms, and the equity premium that investors have assigned to the strategy could compress.
For now, the market has voted with both its wallet and its share price. Metaplanet is no longer a peripheral player in the corporate Bitcoin landscape. It is one of the largest holders in the world, and it has signalled an intention to go much further.
