Japanese Bitcoin treasury company Metaplanet has just announced that it accumulated 4,279 BTC during the fourth quarter of 2025. Metaplanet Spent $451 Million On Bitcoin In Q4 2025 As revealed by Metaplanet CEO Simon Gerovich in a new X post , the Bitcoin treasury company participated in some fresh accumulation over Q4 2025. In total, the firm added 4,279 BTC at an average buying price of $105,412 during this period. The latest announcement has followed three months of no new purchases from Metaplanet. The last time that the Japanese company added more BTC was in September, with two big buys involving more than 5,000 tokens each occurring in the second half of that month. About a week or so after the second of those purchases, Bitcoin formed a high above $126,000, which has acted as the top of the bull market so far. The firm has not been making announcements since then, which may be due to the fact that the asset has witnessed a notable drawdown. Nonetheless, the new announcement suggests that Metaplanet was silently buying tokens in the background, with the company only choosing to unveil it as 2025 approaches an end. As a result of this accumulation, Metaplanet’s holdings have grown significantly. Before the Q4 2025 buying spree, the firm held 30,823 BTC. Now, that figure has risen to 35,102 BTC. The Q4 2025 treasury expansion cost the company a total of $451.06 million, but due to the decline in the cryptocurrency’s price recently, the value of the tokens is down to $376.26 million today. The new accumulation isn’t the only portion of the Bitcoin treasury that has gone underwater; the firm’s entire holdings are in fact currently in a state of loss. With a cost basis of $107,606 per token, Metaplanet’s 35,102 BTC holdings cost $3.78 billion to assemble. Today, these coins are worth just $3.08 billion. Metaplanet is currently the fourth largest corporate holder of BTC in the world, as rankings from BitcoinTreasuries.net show. Even with its Q4 2025 buying, Metaplanet is still more than 8,000 BTC behind Twenty One Capital, which holds 43,514 BTC. Thus, Simon’s company will need a couple more purchases of this size to close in the gap. In the table, it’s apparent that Strategy , the OG treasury firm, is in a different stratosphere from the rest of the names on the list, with its total Bitcoin holdings standing at 672,497 BTC right now. Unlike Metaplanet, the Michael Saylor-led company continued to make regular purchase announcements even as BTC went through its bearish shift. The latest of these came up this Monday, with the firm loading up on 1,229 BTC. BTC Price At the time of writing, Bitcoin is floating around $88,000, unchanged from one week ago.
