Metaplanet, a Bitcoin treasury company, has moved from a small-cap to a mid-cap stock in FTSE Russell’s September 2025 Semi-Annual Review. The upgrade has secured its inclusion in the FTSE Japan Index, which features mid-cap and large-cap companies listed on Japanese exchanges.
The FTSE Russell review happens quarterly, and the decision followed Metaplanet’s strong second-quarter performance. With this inclusion, Metaplanet is also added to the FTSE All-World Index, which tracks the largest publicly listed firms by market capitalisation worldwide.
Being part of these major stock market indexes means Metaplanet can attract fresh capital flows into Bitcoin from traditional markets. It also gives passive investors exposure to the world’s largest cryptocurrency through their index-based investments.
Outperforming Japan’s Blue Chips
Metaplanet reported a year-to-date gain of around 187% in August, far outpacing the 7.2% rise of the Tokyo Stock Price Index (TOPIX) Core 30. The benchmark includes Japan’s biggest manufacturing and technology names such as Toyota, Sony, and Nintendo.
The company currently holds 18,888 BTC in its corporate treasury, making it the seventh-largest publicly traded holder of Bitcoin, according to BitcoinTreasuries. This puts it ahead of Coinbase, Tesla, and Hut 8 Mining in terms of Bitcoin reserves.
Metaplanet was originally a hotel operator but rebranded in 2024 as a Bitcoin treasury company. It is now Japan’s largest corporate holder of Bitcoin.
