US-listed Bitcoin mining companies saw their collective market cap peak at $22.8 billion on June 15, driven by soaring stock prices this month. JP Morgan attributes the surge to increased network hashrate share and ventures into AI data centers. Marathon Digital leads with a $5.3 billion market cap, followed by CleanSpark and Riot Platforms. Strategic partnerships and acquisitions, like Core Scientific’s rejection of a $1.6 billion bid, also fueled growth.
