Metaplanet, a Bitcoin (BTC) treasury firm, has been upgraded from small-cap to mid-cap stock in FTSE Russell’s September 2025 Semi-Annual Review, securing its position in the flagship FTSE Japan Index.
The index provider updates and rebalances indices quarterly. Following Metaplanet’s robust Q2 performance, it has been included in the FTSE Japan Index, which features mid-cap and large-cap companies listed on Japanese exchanges.
Being part of the FTSE Japan Index automatically adds Metaplanet to the FTSE All-World Index, which comprises the largest publicly traded companies by market capitalization in each geographic area.

Metaplanet currently has 18,888 BTC in its corporate treasury, ranking it as the seventh-largest publicly traded holder of the capped supply, according to BitcoinTreasuries.
Originally a hotel operator, Metaplanet rebranded as a Bitcoin treasury firm in 2024. It now holds more BTC than Coinbase, Tesla, and the Hut 8 mining company, making it Japan’s largest BTC treasury by holdings.
In July, CEO Simon Gerovich indicated that a portion of the BTC reserve would be used to acquire additional income-generating businesses, hinting at potential acquisitions of a digital bank or entities related to digital assets and finance.
The company’s executives have set a target of accumulating 210,000 BTC by 2027, equating to 1% of the total supply of 21 million.
