Metaplanet was upgraded by FTSE Russell from small-cap to mid-cap in the semi-annual review in September 2025, thereby being added to the FTSE Japan Index and subsequently the FTSE All-World Index.
This move makes the stock more attractive to passive capital flows from index-tracking funds, while also providing investors with indirect exposure to Bitcoin – the focal asset in Metaplanet's treasury strategy.

FTSE Russell upgraded Metaplanet to mid-cap and added it to the FTSE Japan Index, leading to the FTSE All-World Index (source: FTSE Russell).
YTD performance as of August 2025 is approximately 187%, well above TOPIX Core 30 at 7.2% (source: Metaplanet Q2 report).
Metaplanet holds 18,888 BTC, ranking 7th among publicly listed companies globally, aiming for 210,000 BTC by 2027 (source: BitcoinTreasuries, company announcement).
How did Metaplanet get upgraded to mid-cap?
According to the semi-annual review announcement in September 2025 by FTSE Russell, Metaplanet was upgraded from small-cap to mid-cap and added to the FTSE Japan Index following outstanding Q2 results (source: FTSE Russell).
FTSE Russell updates and rebalances the index quarterly, with selections based on market capitalization and filtering criteria. The upgrade reflects the improved size and liquidity of Metaplanet, along with its outstanding stock performance in the first half of the year (source: FTSE Russell).
Being included in the FTSE Japan Index means the stock qualifies for a broader investor base, especially from passive funds tracking the index in Japan and globally.
What does entering the FTSE Japan Index and FTSE All-World mean?
Adding to the FTSE Japan Index while bringing Metaplanet into the FTSE All-World Index opens the door for index-tracking capital and increases international presence (source: FTSE Russell).
The FTSE Japan Index focuses on mid-cap and large-cap companies listed in Japan, while FTSE All-World aggregates large companies by region. When rebalancing, index-tracking funds typically adjust their portfolios to limit deviation, helping new index stocks to receive stable passive demand according to quarterly rebalancing schedules (source: FTSE Russell).
Especially for Metaplanet, this also creates indirect exposure to Bitcoin for stock investors, due to the treasury strategy focusing on BTC.
How has Metaplanet outperformed the Japanese blue-chip group?
Metaplanet recorded a YTD increase of approximately 187% as of August 2025, far exceeding the TOPIX Core 30's increase of 7.2% YTD, according to the company's Q2 financial report.
This result indicates that the stock benefits from the Bitcoin treasury strategy and market expectations for expanded operations. The price trend over one year in JPY shows a strong upward trend, as noted by data market platforms like Yahoo Finance (source: Metaplanet Q2 report; Yahoo Finance).
However, the performance disparity compared to blue-chip indices also comes with the risk of higher volatility, due to dependence on digital assets in the balance sheet.
How much BTC is Metaplanet holding and what is its global position?
Metaplanet currently holds 18,888 BTC in its treasury, ranking 7th in BTC ownership among publicly listed companies, according to BitcoinTreasuries.
This volume surpasses Coinbase, Tesla, and Hut 8 according to the same source data, making Metaplanet the largest Bitcoin treasury company in Japan based on BTC held (source: BitcoinTreasuries).
A large BTC size means high sensitivity to Bitcoin price fluctuations, but also reinforces the argument for indirect exposure for stock investors as major indices add Metaplanet to their baskets.
Who is Metaplanet and why the repositioning in 2024?
Metaplanet was originally a hotel operating business, successfully repositioned as a Bitcoin treasury company since 2024 to focus on accumulating and managing BTC as a strategic asset.
The model transformation helps the company align its positioning with the digital asset narrative, tapping into the demand for BTC exposure through the stock market. From a strategic perspective, repositioning allows for optimizing capital structure, enhancing fundraising ability, and expanding presence in large index portfolios.
With FTSE Russell upgrading, Metaplanet's transformation story is more clearly recognized by the market.
What is Metaplanet's next growth strategy?
In July 2025, CEO Simon Gerovich stated that the company could use some BTC to acquire cash-generating businesses, including the possibility of acquiring digital banks or related digital asset sectors, while targeting 210,000 BTC by 2027.
The M&A plan based on the strong BTC-rich balance sheet can diversify revenue streams and limit dependence on Bitcoin cycles. The target is 210,000 BTC, equivalent to 1% of the total supply of 21 million, reflecting ambitions to scale the treasury.
Execution needs careful risk management, balancing BTC accumulation, operational liquidity, and listing governance requirements in Japan.
How might the addition to the index affect capital flows?
Passive funds tracking the FTSE Japan Index and FTSE All-World typically rebalance on schedule, which may create mechanical buying demand for Metaplanet's stock around reporting periods (source: FTSE Russell).
While not guaranteeing net capital flow, the rebalancing schedule helps create repeat demand, while active funds may consider positions based on Bitcoin narratives and outstanding performance. The net impact depends on stock liquidity, index basket weight, and market conditions.
Investors need to monitor official announcements from FTSE Russell and index-tracking funds regarding schedules and implementation methods.
What are the main risks investors need to be aware of?
Key risks include Bitcoin price volatility directly impacting treasury value and market expectations for the stock.
Liquidity risk also arises when passive capital flows fluctuate sharply around rebalancing periods. Additionally, changes in the regulatory framework regarding digital assets may impact the company's holding strategy and M&A activities.
Investors should look at a combination of financial report data, FTSE Russell index schedules, and market data to assess risk-return.
