Core Scientific closes $3.3B bond, expands to 1.5 GW, and retains hyperscaler interest after exclusivity expiry

The Bitcoin miner turned AI data center platform raises cash, lifts margin guidance, and advances multiple gigawatt-scale campuses.

CORZ · Earnings Call · 2026-05-06

Core Scientific reported Q1 2026 results on May 6, and the story is one of accelerating transition to an AI data center platform. The company announced a $3.3 billion project bond financing, a path to 1.5 gigawatts at two campuses, and a raised margin target for its CoreWeave contract.

Capital Formation and Expansion

The most striking development is the billable capacity ramp. Management disclosed that they have delivered 243 megawatts of billable capacity to CoreWeave, with another 200 megawatts expected in the coming months. This is the culmination of years of execution. As CFO Jim Nygaard said: “During the first quarter, we reached an important inflection point as our colocation revenue scaled to a level sufficient to cover operating costs and began expanding margins.” — Jim Nygaard, Chief Financial Officer · 2026-05-06 The company is also investing ahead of contracts, securing land, labor, and equipment to protect timelines. CEO Adam Sullivan emphasized: “The fact that we have five facilities fully leased and financed by our tenant is a meaningful differentiator.” — Adam Sullivan, Chief Executive Officer · 2026-05-06 They raised $3.3 billion via a project bond at 7.75% interest. Nygaard noted: “We closed our previously announced $3.3 billion CoreWeave project bond financing at a 7.75% interest rate, which we view as a highly attractive cost of capital for a financing of this scale.” — Jim Nygaard, Chief Financial Officer · 2026-05-06 The expansion to 1.5 gigawatts at Pecos and Muskogee is a major strategic move. The company is leveraging low emission behind-the-meter generation and grid solutions to achieve scale. This positions Core Scientific as one of the largest AI infrastructure developers in the market.

Exclusivity Expiry and Hyperscaler Demand

A notable moment was the expiry of an exclusivity arrangement with a hyperscaler for Pecos and Muskogee. Instead of cooling demand, three hyperscalers immediately engaged on those same sites. Sullivan said: “That exclusivity is now expired. However, three hyperscalers immediately engaged on those same sites.” — Adam Sullivan, Chief Executive Officer · 2026-05-06 This suggests strong demand for the assets. In the Q&A, he elaborated:

The exclusivity that expired-the customer is still at the table and still interested in those sites.

This is a positive signal for the company's go-to-market approach. The company is now in active discussions with multiple hyperscalers, as well as chip makers and AI labs. This is a key theme across the earnings call.

Financial Trajectory and Margin Improvement

The financials are improving as colocation revenue scales. Gross margin jumped to 26.1% from 10.3% a year ago, reflecting the higher-margin colocation business. The company also raised its target cash gross profit margin for the CoreWeave contract to 80%-85%. This is a clear sign of confidence in the cost structure. Revenue grew 45% yoy to $115M, though net income remains negative due to heavy investment. Capital expenditure is ramping significantly as the company builds out its pipeline. Gross margin improved to 26.1% in Q1 2026 from 10.3% a year earlier, a +15.8pp swing driven by the shift to high-density colocation. Despite the negative earnings, the company's cash position is being managed through the project bond. The lockbox structure ensures debt service, but the proceeds are largely available for new projects. This is a sophisticated capital approach that enables the company to invest ahead of contracts. The company is also winding down its Bitcoin mining operations. Sullivan stated that by the end of 2026, they will have only one or two sites mining Bitcoin. This is a deliberate shift to focus on the higher-value colocation business. Prior commentary from March highlighted the company's previous exclusivity: “we've been engaged with a number of different counterparties... we sit with 500 megawatts under exclusivity arrangements” — Adam Sullivan, Executive (likely CEO or President) · 2026-03-03 That situation has clearly evolved. Earlier, in May 2025, management was already confident in the CoreWeave relationship: “we're really excited about the CoreWeave contracts” — Adam Sullivan, Executive (likely CFO or senior management) · 2025-05-07 Now they are delivering on that promise. The high density colocation lead is compelling, and the company is well positioned in a demanding market. However, the stock has pulled back from its June 2026 peak, suggesting some skepticism about execution or valuation. The recent 90-day trend shows a -38.9% drawdown from the peak. Overall, Core Scientific is executing on its pivot from Bitcoin mining to AI data center infrastructure, and the Q1 report provides strong evidence of that transition.
