A Decisive Break From the Mining Era
Core Scientific has formally set a deadline for its complete departure from Bitcoin mining, confirming it will finish shutting down all mining operations before the close of 2026. The company will enter 2027 operating solely as a high-density colocation provider focused on artificial intelligence and high-performance computing workloads.
"We expect to complete the wind-down during the fourth quarter and enter 2027 as a pure-play, high-density colocation provider," CFO Jim Nygaard stated during the firm's third-quarter earnings call on Thursday. The remark locks in a concrete completion timeline for the total exit from both self-mining and hosted mining.
Earlier in a July quarterly filing, Core Scientific had already noted that its hosted-mining segment would cease operations by December 31, while self-mining was in the process of being phased out. Thursday's comment from Nygaard crystallizes the target date for the company's full withdrawal from the Bitcoin mining industry.
Revenue Shift Tells the Story
The latest quarterly numbers illustrate just how dramatically the business mix has changed. Self-mining revenue in Q3 stood at $12.3 million, a sharp decline from $57.4 million in the same period a year earlier. Revenue earned by hosting third-party miners also contracted, falling to $5.2 million from $8.7 million year-on-year.
Taken together, all Bitcoin mining activity generated only $17.5 million, representing a mere 7.5% of the company's total $232.9 million in third-quarter revenue. By contrast, colocation services contributed $215.4 million, underscoring that the AI and HPC hosting business has become the overwhelming engine of the company's income.
Nygaard also disclosed that Core Scientific had roughly half as many miners online at the end of September compared with the end of 2025, reflecting the accelerated pace of the wind-down.
From Expansion to Full Commitment
The pivot toward AI hosting originated in 2024. Core Scientific signed its first hosting agreement with CoreWeave in March of that year, followed by a substantially larger deal announced in June. At the time, the company framed the AI work as a complement to its existing mining operations. The June 2024 announcement specifically highlighted the intention to preserve Bitcoin mining capacity alongside the new hosting business.
That posture shifted over the following months. By December 2025, The Wall Street Journal reported that Core Scientific was already targeting a full wind-down of its mining operations by 2028. The company has now pulled that timeline forward by two years, with the complete exit expected well before 2027.
The financial pressures of the transition have been substantial. In the first quarter of 2026, Core Scientific booked $266.5 million in mining-related asset impairments, attributing the write-downs to softer Bitcoin prices, historically depressed hashprice levels, and declining resale values for digital-asset mining hardware in the secondary market. During the second quarter, the firm terminated its mining-equipment agreement with Block and Proto, recognizing a $41.9 million loss as part of the broader restructuring.
Political Headwinds for AI Infrastructure
Core Scientific's planned pivot lands against a backdrop of growing political uncertainty in the United States. According to a Wednesday report from Reuters, opponents of large-scale data-center development emerged among the beneficiaries of the Democrats' sweeping midterm electoral gains. The backlash is driven largely by concerns over rising electricity bills and the heavy strain that hyperscale facilities place on local power grids and community resources.
For the broader cryptocurrency sector, Core Scientific's exit marks another milestone in the ongoing reallocation of capital and infrastructure away from Bitcoin mining and toward AI workloads. With one of the industry's most recognizable names formally leaving the mining space, the competitive landscape for Bitcoin hashpower continues to consolidate, while the demand for high-density compute capacity in AI remains the dominant force reshaping data-center economics.
