Bitcoin (BTC) finance company Metaplanet has been upgraded from small-caps to intermediate stocks in a semiannual review in September 2025 by index provider FTSE Russell, and increased it to include it in the flagship FTSE Japan Index.
Index providers updated and rebalanced their indexes quarterly, and following Metaplanet’s strong Q2 performance, they were added to the FTSE Japan Index, the stock market index for intermediate and large companies listed on Japanese exchanges.
The inclusion of Metaplanet in the FTSE Japan Index means that market capitalization in each geographical region will automatically be added to the FTSE global index of the largest public companies.
