Core Scientific reported a $347 million loss for the first quarter of 2026, as its Bitcoin mining revenue fell 55% year-over-year. The company also noted a shift in its business: high-density colocation became its single largest revenue driver, overtaking mining income for the first time.
The $347 million hole
The loss, disclosed in the company's Q1 earnings statement, marks a steep reversal from prior quarters. Core Scientific did not break out the components of the loss, but the 55% drop in mining revenue was the most prominent headline. Revenue from mining operations has been under pressure across the industry as Bitcoin's price and network difficulty have fluctuated, though Core Scientific's decline outpaced some peers. The company's total revenue figures were not immediately available, but the loss figure suggests expenses or writedowns also weighed heavily.
Mining revenue cut in half
Bitcoin mining revenue fell to roughly half of what it was a year ago. The company didn't specify the exact figure, but the 55% year-over-year decline underscores the headwinds facing publicly traded miners. Core Scientific has been among the largest miners by hashrate, but the revenue drop suggests its fleet of ASICs is generating less income per unit of computing power. The decline comes despite a period of relatively stable Bitcoin prices, pointing to increased competition and rising network difficulty as key factors.
Colocation takes the lead
High-density colocation — where Core Scientific rents out data center space and power infrastructure for compute-intensive clients — became the company's top revenue source in Q1. The segment had been growing steadily, but this quarter marked the first time it surpassed mining revenue. The shift reflects a broader pivot by some mining firms to diversify beyond Bitcoin, offering hosting and high-performance computing services to AI and cloud customers. Core Scientific didn't name any colocation clients in the filing, but the segment's rise suggests the company is leaning into the data-center business as mining margins tighten.
High-density colocation involves providing specialized infrastructure for workloads that require significant power and cooling, such as AI model training and scientific computing. For Core Scientific, this business represents a less volatile revenue stream compared to mining, though it requires substantial capital investment in facilities and equipment.
The Q1 report leaves Core Scientific in a familiar bind: its legacy mining operation is shrinking, but its new revenue driver is still relatively young. The company will need to show that colocation can sustain the growth needed to offset further mining declines. Investors will be watching the Q2 numbers closely for signs that the pivot is gaining traction.
