Bitcoin Treasury Giant Metaplanet Drops 7% as Japan Considers DAT Clampdown
Shares of Metaplanet, a prominent corporate holder of Bitcoin, tumbled roughly 7% after Bloomberg reported that the Japan Exchange Group (JPX) is considering steps to limit the expansion of so-called digital-asset treasury (DAT) firms. The move would target companies that accumulate large crypto reserves on their balance sheets, a practice critics say can amplify market concentration and systemic risk. Market participants say the significance goes beyond one stock: curbs on DATs could remove a structural source of institutional demand for Bitcoin, boost volatility, and prompt treasury teams to rethink crypto allocations. Investors and analysts are watching for details—caps, disclosure rules, or capital requirements—from JPX and Japanese regulators, as the specifics will determine how acute the impact on crypto markets and corporate strategy might be.
