Metaplanet, a Bitcoin treasury company based in Japan, has become the country's most traded and most volatile stock. On May 23, 2025, the company saw a trading volume of 158.8 million shares and a total value of ¥132 billion (approximately $921 million), marking it as Japan's top stock by liquidity and volatility. This surge in trading activity is attributed to increased investor interest in Bitcoin-linked equities following Metaplanet's aggressive accumulation of Bitcoin. However, the following day, May 24, 2025, Metaplanet's stock experienced a sharp decline, hitting the daily trading limit down (stop loss) amid a broader 7.5% drop in strategy stocks linked to Bitcoin's price fall.
