Core Scientific posted $80 million profit from AI hosting after shedding $56 million in bitcoin mining losses, validating the pivot to compute infrastructure.

Core Scientific, transitioning from Bitcoin mining to AI data-center operations, reported sharply divergent financial results by segment in the second quarter. While its self-mining business posted a negative 56% gross margin, the company's high-density colocation segment generated $80 million in gross profit—exceeding Core Scientific's $70 million consolidated total.

The mining segment produced $21.5 million in revenue against $33.7 million in cost of revenue, leaving a $12.2 million gross loss for the three months ended June 30. Cost of revenue included $17.9 million in power fees, $9.9 million in depreciation, and other operating expenses. According to the company's earnings call, CFO Jim Nygaard explained that Core Scientific was operating its remaining mining capacity primarily to offset contractual power costs during the wind-down. By quarter-end, the company was self-mining at only two sites and had reduced its active miner count by nearly 30% compared to the first quarter.

In contrast, the colocation segment moved decisively in the opposite direction. High-density colocation services—providing powered data-center capacity for AI customers—generated $136.7 million in revenue and $80 million in gross profit at a 59% margin. The colocation segment's profitability exceeded the company's entire consolidated gross profit, with mining and other segment losses pulling the companywide figure lower.

Core Scientific reported 395 megawatts of billing colocation capacity at the end of Q2 and 437 MW by mid-July, representing approximately $635 million in average annualized colocation revenue. However, this operational footprint remains well below the roughly 1.1 gigawatts of leased customer power capacity tied to more than $24 billion in potential contracted revenue. The company's relationship with AMD is anchored by 15-year agreements covering approximately 530 MW across five sites and more than $14 billion in base contracted revenue, with a broader relationship capable of supporting up to 2.5 GW, though that figure represents prospective capacity rather than built or billing resources.

Core Scientific reported a $1.16 billion net loss for the quarter, though this figure overstates operational damage. Approximately $1.05 billion of the loss stemmed from a fair-value expense for warrants and contingent value rights driven by the rising stock price.

The company states it is repurposing its remaining mining facilities for high-density colocation "as circumstances allow," but did not identify Q2 as a conversion trigger or indicate that conversion has become compulsory. The quarter demonstrates why mining is losing its economic claim on the company's power and capacity: one segment produced a negative gross margin while the other generated more profit than the company recorded in total.
