[Bitcoin Mining Profitability Under Pressure, Mining Company Stocks Rise Due to Target Price Upgrades] The Miner Mag report shows that the Bitcoin mining industry is facing profitability pressure. In October, network hash rate hit a record high of 1.16 ZH/s, but Bitcoin's price fell to around $81,000, and hash price dropped to $35/PH/s, below the median of $45/PH/s for publicly listed mining companies, with some nearing breakeven. The payback period for mining machines has extended to over 1,200 days, and financing costs have risen. Although mining companies are accelerating their shift to AI and high-performance computing (HPC), related revenues remain insufficient to offset the decline in Bitcoin mining income. After JPMorgan raised the target prices for CleanSpark, Cipher Mining, and IREN, the stock prices of the top ten publicly listed mining companies rose across the board on Monday. In November, IREN signed a five-year $9.7 billion GPU cloud service agreement with Microsoft.
