Core Scientific (CORZ) to Exit Bitcoin Mining by Year-End as Colocation Hits $215 Million
Core Scientific will complete its exit from bitcoin mining by year-end and enter 2027 as a pure-play high-density colocation provider, management said on Thursday’s third-quarter earnings call, capping a pivot that has already cut the company’s mining fleet nearly in half.
Chief Financial Officer Jim Nygaard told investors the company expects to “complete the wind-down during the fourth quarter.” Chief Executive Officer Adam Sullivan put the same end date more bluntly: “We expect to complete our exit from Bitcoin mining by year end.” The comments landed alongside a results release filed with the SEC that shows how far the shift has already gone.
Colocation revenue climbed nearly 60% sequentially to $215.4 million in the quarter ended Sept. 30, the earnings exhibit shows. Digital asset self-mining revenue fell to $12.3 million, down about 79% from $57.4 million a year earlier. Hosted mining for third parties added just $5.2 million. Of $232.9 million in total revenue, colocation now accounts for roughly 92%.
Self-mining posted a $7.5 million gross loss in the quarter. Colocation gross profit was $128.4 million, a 60% margin. Adjusted EBITDA more than tripled sequentially to $133.6 million, with the margin expanding to 57% from 25%.
Nygaard said Core Scientific had nearly 50% fewer miners online at the end of September than at year-end 2025.
