Core Scientific says it expects to end its Bitcoin mining business in the fourth quarter of 2026. The company plans to start 2027 as a pure colocation firm. That means it will rent data center space and power to clients.
The Core Scientific Bitcoin mining exit follows a year in which mining shrank to a small slice of sales. The plan is a goal and not a done deal, so the end date can still shift.
The chief financial officer spoke on the Q3 call on November 5. He said the company expects to finish the wind-down in the fourth quarter. He added that the firm will enter 2027 as a high-density colocation firm.

Colocation means clients place their own computers in the company’s data centers. The company then supplies the space, power, and cooling. High-density means the machines use a lot of power in a small area, which suits AI work.
A July filing also said that hosted mining for outside clients would end by December 31.
The Q3 numbers show the shift clearly. Total revenue was $232.9 million, and $215.4 million of it came from colocation. Mining brought in about $17.5 million, or 7.5% of the total. Colocation revenue grew almost 60% from the second quarter.

In the first quarter, the company also wrote down $266.5 million tied to mining. It blamed weaker Bitcoin prices and low hash price, which is what a miner earns for each unit of computing power. Both items appear in its SEC filings.
The public summaries of the call do not say if every mining site will be shut by year end. They also do not say what the company will do with its miners or any Bitcoin it still holds. Until the Q4 report comes out, the exit is still a plan.
One firm leaving does not stop the Bitcoin network, since many miners around the world keep it running. Still, the move shows that a miner can pick AI and computing demand over mining when profits fall. Readers who follow crypto news may want to watch miner revenue and hashrate in the months ahead.

The company has set a clear goal. Mining is already a small part of its income, so the plan looks doable. A goal is not a promise, though. Plans like this can slip if power deals, equipment sales, or client builds take longer than expected.
