Core Scientific Plans $3.3 Billion Debt Offering to Fund AI Data Center Expansion

Core Scientific, a bitcoin miner that emerged from bankruptcy in January 2024, announced a $3.3 billion junk bond offering to refinance debt and fund AI data center expansion. The company has pivoted from struggling bitcoin mining operations—selling $175 million in bitcoin in March 2026—to building six AI facilities leased to CoreWeave under a 12-year agreement expected to generate $10 billion in revenue. The move reflects broader industry trends as bitcoin mining profitability declined following the April 2024 halving and rising costs, while AI infrastructure demand has pushed data centers to capacity limits. Core Scientific joins a wave of AI-linked borrowers who have raised $17.9 billion in speculative-grade bonds in 2026, with shares up 42% year-to-date as investors bet on the AI hosting pivot.
