PANews reported on August 25 that according to Cointelegraph, Bitcoin fund management company Metaplanet has been upgraded from a small-cap stock to a mid-cap stock in the index provider FTSE Russell's September 2025 semi-annual assessment, thereby including it in the flagship FTSE Japan Index.

The index provider, which updates and rebalances its indices quarterly, has included Metaplanet in the FTSE Japan Index, a stock market index covering mid-cap and large-cap companies listed on Japanese exchanges, based on its strong second-quarter performance.

Metaplanet's inclusion in the FTSE Japan Index means it will automatically be included in the FTSE All-World Index, which covers the largest listed companies by market capitalization in each region.
