Cost basis: $42.87B
BTC per share: 0.00214106

→ Strategy (MicroStrategy) remains the largest public Bitcoin holder, far ahead of the rest. This week’s buy cements its dominant position, now holding nearly 3% of all Bitcoin that will ever exist.
YTD BTC yield sits at 20.2%, market NAV multiple at 1.669×. No other public company comes close in terms of BTC per share ratio.

% of total BTC supply: ~0.0636%
BTC-to-market-cap ratio: ~26.5%

→ Metaplanet mirrors MicroStrategy’s approach in Asia. The firm is following its “210 Million Plan,” aiming to raise $5.4B by 2027 to acquire 210,000 BTC (~1% of supply).
With this week’s addition, Metaplanet needs ~3,670 BTC to overtake Riot Platforms as the #4 public holder.
