Notable Filings
Metaplanet's 5,419 BTC purchase represents the week's dominant move by capitalization; the Tokyo-listed company continues building its Bitcoin treasury. SharpLink Gaming (SBET) stacked 1,498 ETH, while Def Consulting (4833.T), a Japan-listed entity, initiated its Ethereum treasury with 792 ETH at $3.27 million. Solana Company (HSDT) entered the SOL cohort with a 760,190 SOL position, making it the second-largest SOL stack among corporate filers. Forum Markets (FRMM), formerly ETHZilla, added 18 ETH for $71,077, signaling continued small-scale Ethereum accumulation.

One Chart
BTC continues to dominate the corporate-treasury asset mix by USD value: Metaplanet's single purchase ($632.5 million) exceeds the combined USD value of all ETH ($8.4 million across three filers) and SOL ($175.6 million, nearly all from one stacker) acquisitions. The 6-to-1 ratio of BTC dollar value to SOL, despite SOL's 140x native-token count advantage over BTC, reflects the persistent pricing and liquidity gap between the two assets in institutional balance-sheet strategy.
