Odaily Planet Daily News Bitcoin miners are currently facing a choice: grab mining market share or go all in on artificial intelligence? From the perspective of equity returns, this is the state of the mining industry in September. Several large mining companies with higher market capitalizations, MARA Holdings (MARA), Riot Platforms (RIOT) and CleanSpark (CLSK), all increased their share of total Bitcoin mining volume last month compared to August. These companies have stronger balance sheets and larger mining operations, which helped them cope with the decline in mining profitability caused by the Bitcoin halving in April. However, investors did not pay a premium for these stocks as they still performed poorly in September. At the same time, miners focusing on artificial intelligence and HPC computing, such as Core Scientific (CORZ), TerraWulf (WULF) and IREN (IREN), outperformed Bitcoin in September. In addition, the recent approval of the spot Bitcoin ETF in the United States has also reduced investor interest in mining stocks. Instead, investors are rewarding miners that use part of their data centers to host AI and HPC-related machines to diversify their revenue. (CoinDesk)
