According to Mars Finance, the latest published production data for the second quarter shows that listed and upcoming mining companies are consolidating their share of Bitcoin output. The total market share of these 18 companies increased from 21.1% in the same period last year to 32.5% in the second quarter. However, this growth is not uniform. The rise in total market share is not comprehensive but is mainly driven by MARA, Cango, IRE, and CleanSpark, which significantly increased their computing power, offsetting the losses of miners who have turned to HPC or faced stagnation.
