Core Scientific, Inc./tx (CORZW)

Core Scientific was, until recently, one of the largest publicly traded bitcoin miners in the United States. The company has begun a dramatic pivot: it is selling much of its bitcoin holdings to fund the conversion of its data-centre capacity toward providing computing infrastructure to artificial-intelligence companies. The warrants trade on Nasdaq as CORZW; common stock is CORZ.

The bitcoin mining foundation

Core Scientific built its business on bitcoin mining—the process of solving cryptographic puzzles to validate transactions on the Bitcoin blockchain and earn newly created coins as a reward. Profitable bitcoin mining requires three inputs: hardware (specialized chips called ASICs), electricity at the lowest possible cost, and thermal infrastructure to cool the equipment. Core Scientific assembled all three. The company operates data centres in Texas, Georgia, Kentucky, and other states where electricity is cheap (often from natural gas or hydroelectric sources), runs industrial-scale cooling systems, and aggregates capital to buy and deploy thousands of mining machines.

For nearly a decade, this was a durable business. Bitcoin mining is one of the few blockchain activities with a clear revenue stream: whenever a block is validated, the miner is paid in new bitcoin plus transaction fees. The price of bitcoin fluctuates, but the mining operation itself is relatively stable—machine it, plug it in, collect the proceeds. At its peak, Core Scientific was the leading bitcoin miner by hash rate (the computational power directed at mining), having claimed that distinction for three consecutive years.

But bitcoin mining has been under structural pressure. As the network has grown and competition for blocks has intensified, individual miners’ returns per unit of computing power have declined. Mining also consumes vast amounts of electricity—a single large-scale operation can use as much power as a small city—which makes miners vulnerable to energy costs and increasingly exposed to regulatory scrutiny over their environmental impact.

The near-death and the emerging pivot

Core Scientific filed for Chapter 11 bankruptcy in 2022 when the price of bitcoin collapsed and the company could not service its debt. The company emerged from bankruptcy in 2024, significantly deleveraged, with a cleaner capital structure and renewed access to capital. But the emerging company faced a choice: continue betting on bitcoin mining in a landscape of declining margins, or redeploy its most valuable asset—thousands of megawatts of contracted electricity and the data-centre infrastructure to use it—toward a new customer base.

That customer base is artificial-intelligence companies. Training and running large language models, diffusion models, and other modern AI systems requires immense computational capacity. Nvidia GPUs and other specialist chips are the input, and the output is AI inference and training services that companies like OpenAI, Anthropic, and others provision to downstream users. Power-hungry AI companies are willing to pay premium rates for clean, reliable electricity and colocation facilities that can house thousands of GPUs. Core Scientific saw an opportunity.

The data-centre colocation strategy

Rather than selling electricity to AI companies at wholesale rates, Core Scientific is selling computing capacity—renting space in its data centres, providing power delivery, cooling, and networking to customers who bring their own equipment or lease it on-site. This colocation model has several advantages over mining: first, the company collects a margin on electricity without bearing the commodity risk itself (the customer pays per unit used). Second, it reduces exposure to cryptocurrency volatility—the company’s revenue no longer depends on the price of bitcoin. Third, it taps into a booming market; AI infrastructure is one of the hottest categories in technology infrastructure today.

The colocation revenue growth has been swift. In Q1 2026, colocation revenue reached $77.5 million, up from $8.6 million a year earlier—a roughly ninefold increase. This has become Core Scientific’s largest business line, overtaking mining revenue. The company has also acquired Polaris DS LLC, an Oklahoma-based bitcoin miner, for $421 million, acquiring 440 megawatts of contracted power capacity. That acquisition is another signal of the pivot: Core Scientific is buying capacity (power and space) rather than mining equipment, planning to repurpose the power for AI colocation rather than bitcoin mining.

The regulatory environment

Bitcoin mining exists in a light regulatory environment in the United States (though this is changing in some states). The activity itself is not banned or heavily licensed; it is treated as a business using electricity. But three regulatory currents are reshaping the landscape. First, environmental rules are tightening: some states are reviewing mining’s power consumption and water use, and in some cases have restricted new mines or required higher environmental-impact standards. Second, banking regulations have become stricter for crypto-friendly financial institutions, which limits Core Scientific’s access to banking services in some jurisdictions. Third, as the AI sector grows, power constraints and grid stability become political issues, and data-centre operators—whether for crypto or AI—may face new rules around power procurement, peak-load management, and grid reliability.

Core Scientific’s shift toward AI colocation may provide some insulation from crypto-specific regulation, but it introduces a new set of regulatory risks: data privacy (customers may be processing sensitive data), export controls (if the company provides AI computing power to foreign customers, certain models may be restricted), and labour rules (data-centre operations employ technicians and engineers subject to employment law and safety standards).

The competitive position

Core Scientific’s primary assets in the colocation business are megawatts of power, physical space, and operational expertise in managing large-scale computing facilities. These are defensible only if the company can offer power at a cost and in a location that competitors cannot match. The threat is twofold: first, larger hyperscalers like Amazon, Microsoft, and Google have vast capital and can build their own data centres at scale, potentially displacing specialized operators like Core Scientific. Second, other bitcoin miners and data-centre operators are making similar pivots, flooding the market with colocation capacity and potentially eroding margins.

Core Scientific’s counter-argument is that it has capacity now, contracts for long-term power now, and no legacy consumer-facing business that constrains deployment decisions. It can move fast and serve customers who need computing power urgently. Whether that advantage persists depends on whether AI infrastructure demand stays hot and whether the company can secure additional long-term power contracts to expand capacity.

How to research Core Scientific

The key metrics are megawatts of committed, contracted power and the utilization rate (what percentage of that power is generating revenue). Quarterly and annual filings (SEC CIK 0001839341) disclose these. Watch for new power contracts—these are often announced in press releases and signal that the company is securing additional capacity. The company also publicly discloses bitcoin holdings and bitcoin mining production, which allows investors to track how quickly the company is transitioning away from self-mining toward third-party colocation. Finally, monitor balance-sheet health: the company emerged from bankruptcy with moderate debt, but rapid growth may require additional capital. Track whether that capital is being raised through equity offerings (dilutive to existing shareholders) or asset sales (sales of bitcoin holdings or other assets) or debt (additive to leverage).
