Metaplanet (3350.T) rose ¥48, or 18.97%, to ¥301 by 11:25 a.m. on August 21, reclaiming the psychologically important ¥300 level for the first time in about two and a half months. The stock has gained 36.82% over five trading sessions from its August 17 close of ¥219, following a 16.06% increase to ¥253 on August 20. Bitcoin's advance, supported by U.S. Treasury liquidity measures and renewed discussion of government cryptocurrency holdings, has provided the main catalyst. Metaplanet's stock has moved roughly twice as much as Bitcoin because of its substantial Bitcoin treasury holdings, amplifying both gains and losses. The company also plans to make Nasdaq-listed Super League Enterprise a consolidated subsidiary as the base for its U.S. Bitcoin treasury operations. Despite the rebound, Metaplanet remains down 31.12% year-to-date and 63.56% over the past year. The U.S. Congress is scheduled to vote on the CLARITY Act on September 15, leaving policy developments and Bitcoin's price action as key near-term drivers.
