Metaplanet’s stock has soared nearly 400% in less than two months, surpassing the market capitalization of major Japanese firms like Kioxia Holdings and Tokyo Metro, reaching over ¥1 trillion ($6.9 billion). The company’s Bitcoin yield, a key performance metric, stands at 266.1% year-to-date in 2025, reflecting significant growth in Bitcoin per share. Earlier in June, Metaplanet announced a $5.4 billion equity offering through 555 million shares to fund further Bitcoin purchases, aiming to hold 210,000 BTC by 2027, roughly 1% of Bitcoin’s total supply.
