Core Scientific shares surge while CoreWeave stock slides after aborted merger

Core Scientific's stock rose 75.8% in the first half of 2026, buoyed by long‑term power contracts that support AI data‑center growth. After the $8.7 billion merger with CoreWeave fell apart, the company secured $3.3 billion in bond financing, expanded its power‑capacity pipeline to 4.5 GW and reported quarterly revenue of $115 million, driven mainly by colocation services.

CoreWeave, a GPU cloud infrastructure firm, saw its shares decline about 55‑60% from their 2025 peak, closing at $79.94 on 14 July 2026. The drop follows a failed $9 billion acquisition of Core Scientific, higher‑than‑expected 2026 capital‑expenditure guidance, and competitive pressure from Meta's expanding AI cloud offerings. Investors cite heavy cash burn and execution risk as concerns for the company's path to profitability.
