U.S.-listed Bitcoin miners have achieved a record 26.6% share of the global hashrate in the first two weeks of July, according to JPMorgan. This increase represents a 2.4% gain since June and a 5.6% rise since the last Bitcoin halving. The total market capitalization of 14 U.S. miners tracked by JPMorgan surged by 29% in early July, reflecting optimism about AI and high-performance computing opportunities. Bitcoin mining stocks hit record highs, with Riot Platforms among the companies benefiting from this growth.
