The mining timetable in the filing
In its November 5 Form 10-Q, Core Scientific said it still runs a self-mining fleet at two facilities and hosts mining for one remaining customer. It expects the hosted-mining operation to conclude by December 31, 2026. The same filing says self-mining continues to wind down, but does not commit to shutting down every company-owned machine on that date.
That distinction matters. A headline saying the company will certainly have exited all Bitcoin mining by year-end goes beyond the deadline stated in its written filing. This is a planned transition, not an already completed shutdown. Core Scientific also says it is not buying new mining machines to maintain or expand its hash rate while capacity is reallocated.
Mining's shrinking share of revenue
Core Scientific reported $232.9 million of third-quarter revenue. High-density colocation contributed $215.4 million, self-mining $12.3 million and hosted mining $5.2 million. Together, the two mining segments accounted for roughly 7.5% of revenue. Self-mining alone generated $57.4 million in the comparable quarter a year earlier.
The mix demonstrates how far the business has moved, but colocation revenue should not be confused with guaranteed profit. Building and converting data centers remains capital intensive. Reported quarterly capital expenditures were $985.1 million, and the company cautions that future results depend on delivery schedules, financing and customer contracts.
Why the power is moving to AI workloads
The company's stated strategy is to turn its available power capacity into longer-term colocation revenue from AI and high-performance computing customers. It was billing for 485 MW of capacity at the end of September. Its filing describes 11 data centers in seven U.S. states and continuing work to convert and expand most facilities for the new workloads.
The move also reflects pressure on its mining economics. In the first quarter of 2026, Core Scientific recorded a $266.5 million non-cash impairment of mining-related assets. It cited weaker Bitcoin prices, historically low hashprice and lower secondary-market equipment values. Those are reasons behind this company's decision, not proof that Bitcoin mining is uneconomic for every operator.
What the change means for Bitcoin
For Core Scientific, less mining should reduce direct exposure to BTC prices and network difficulty in its operating results. For the Bitcoin network, the withdrawal of one operator could reduce its contribution to hash rate, but it does not imply an equal fall in total network capacity. Other miners may expand, and retired equipment may find new owners. Measuring the network impact requires evidence of actual shutdowns and observed hash rate, not a corporate target alone.
The next clear milestone is whether hosting for the remaining customer ends on the expected December date. Separate disclosures will be needed to establish when self-mining stops and how quickly new colocation capacity comes online. Until then, the transition is a documented plan in progress, not a completed exit or a reliable signal for Bitcoin's price.
