Bitcoin mining profitability plunged to record lows in late 2025 as the hash rate dropped below $35 per petahash per second, while production costs rose to $44.8 per petahash. This forced miners into payback periods over 1,200 days and drove a major industry shift, with 70% of top mining companies now earning revenue from artificial intelligence infrastructure.
November 2025 marked a turning point for the global Bitcoin mining industry. A confluence of collapsing margins, regulatory pressure, and strategic pivots reshaped the sector’s landscape. Here are the five key trends that defined the month.
Profitability Hits Historic Lows
Network hashrate surged to a record 1.1 ZH/s in October, intensifying competition. Meanwhile, Bitcoin prices dropped to around $81,000, crushing margins across the industry. Machine payback periods have stretched beyond 1,200 days.
MARA CEO Fred Thiel issued a stark warning about the industry’s future. After the 2028 halving reduces block rewards to roughly 1.5 BTC, most business models will collapse. Only miners with access to cheap energy or successful AI pivots will survive, he said.
Financing costs continue to rise as traditional mining revenue shrinks. Even companies transitioning to AI cannot yet offset the decline in Bitcoin income. The squeeze is forcing urgent strategic decisions across the sector.
AI Pivot Accelerates
Seven of the top ten mining companies now generate revenue from artificial intelligence. AI hosting yields already exceed traditional mining returns by roughly 50% per megawatt. The shift is reshaping how the industry measures success.
Bitfarms announced it will phase out Bitcoin mining entirely within two years. Its Washington State facility will be converted into an HPC data center by December 2026. CEO Ben Gagnon said potential returns could surpass all previous mining income.
IREN secured a landmark $9.7 billion, five-year GPU cloud computing agreement with Microsoft. The deal includes a 20% upfront payment. IREN will deploy NVIDIA GB300 GPUs at its Texas facility starting in 2026.
Hut 8 sold four Canadian natural gas power plants totaling 310 MW to TransAlta. The move aligns with its strategic shift toward Bitcoin mining plus HPC infrastructure. CleanSpark aims to become a comprehensive compute platform serving both AI and BTC.
Massive Capital Restructuring
A wave of convertible note issuances is sweeping the industry. CleanSpark raised $1.15 billion at 0% interest. TeraWulf completed a $1.025 billion offering, also at zero percent.
Cipher Mining issued $1.4 billion in senior secured notes at 7.125% yield. IREN plans to raise $2 billion through two separate convertible bond offerings. Bitfarms completed a $588 million convertible debt issuance.
Equipment commitments are equally massive. IREN signed a $5.8 billion agreement with Dell to procure NVIDIA GB300 GPUs. Cipher expanded its Fluidstack agreement, with Google providing $1.73 billion in guarantees.
Canaan secured a $72 million strategic investment from BH Digital, Galaxy Digital, and Weiss Asset Management. The funds will support high-performance computing and the development of energy infrastructure. The company aims to reduce future financing dilution.
Regulatory Polarization
Malaysia has uncovered approximately 14,000 illegal mining operations over the past five years. Stolen electricity has caused roughly $1.1 billion in damage to the state utility TNB. A government task force was established in November to intensify crackdowns.
Russia is deploying AI technology to combat illegal mining. State grid operator Rosseti embeds AI analytics into smart meters to detect power anomalies. One recent bust involved $1.5 million in stolen electricity.
Yet some governments are embracing mining. Japan launched its first government-linked project through a major regional utility. Canaan will deploy water-cooled Avalon miners for grid load balancing by year-end.
Belarusian President Lukashenko declared cryptocurrency mining a national priority for electricity usage. He suggested that crypto could serve as an alternative to reliance on the dollar. About 60% of Russian miners remain unregistered, prompting discussions of an amnesty.
Strategic BTC Accumulation
Leading miners are stockpiling Bitcoin rather than selling into the market. MARA holds 53,250 BTC valued at approximately $5.6 billion. The company ranks second globally in public Bitcoin reserves.
CleanSpark reported total holdings of 13,054 BTC as of November 30. Monthly production reached 587 BTC in November alone—year-to-date mining output totals 7,124 BTC.
Cango holds 6,412 BTC with an explicit commitment to long-term holding. Bitdeer increased its reserves to 2,233 BTC after mining 511 BTC in October. Canaan reached a record 1,610 BTC and 3,950 ETH.
The accumulation strategy signals confidence in Bitcoin’s long-term value. Miners are betting that surviving the current profitability crisis will prove rewarding. Those who hold through the squeeze may emerge as the biggest winners.
