Metaplanet's Bitcoin stash hits 43,000 BTC, making it the world's No. 3 public holder

Metaplanet, a Japanese listed company, has lifted its Bitcoin holdings to 43,000 BTC, according to CoinDesk. Company disclosures show the position now exceeds that of U.S. miner MARA Holdings, placing Metaplanet as the third-largest publicly traded Bitcoin holder worldwide, behind two U.S.-based firms. Disclosures indicate the company returned to buying in Q2 2026 after a brief pause, adding 2,823 BTC for about ¥35.886 billion. The report said additional funding was also used to expand the position, helping reduce the effective cost basis of the newly built stake. At current prices, Metaplanet's 43,000 BTC are valued at roughly ¥409 billion. Over the past two years, the company has invested about ¥659 billion to build its Bitcoin reserve. Data from BitcoinTreasuries.net shows Metaplanet has overtaken MARA Holdings, which holds 36,303 BTC, and is now 514 BTC away from the No. 2 spot globally. MicroStrategy founder Michael Saylor also posted on social media congratulating the company on reaching 43,000 BTC. CoinDesk noted that Metaplanet's market capitalization still sits below the value of its Bitcoin holdings. By contrast, Strategy's market value typically trades about 8% above the value of its Bitcoin reserves, highlighting Metaplanet as an outlier in Asia where the equity valuation has yet to fully reflect the scale of its digital-asset holdings.
