These figures indicate the 10-for-1 stock split on April 1, 2025, and follow US ATM rules, counting moving strike warrants only after they are exercised.
Capital Raises Fuel Bitcoin Expansion

Metrics’ Role and Limitations
BTC Gain indicates how much extra Bitcoin the company has added after adjusting for new shares, while BTC ¥ shows its value in yen. These numbers do not include debt, profits or Bitcoin price changes. The company pays no dividends, and owning its shares does not mean owning Bitcoin.
Metaplanet follows MicroStrategy’s strategy, where it uses Bitcoin as a reserve asset as the yen weakens. In 2025, it earned ¥8.58 billion in revenue and plans to keep growing its Bitcoin holdings.
