AI Cloud Stocks Surge by 12 Trillion Won in a Day, Lawsuit Risks Ongoing

CoreWeave Inc. (NASDAQ: CRWV) jumped 20.48% on February 6, closing at $89.94. Trading volume topped 23.32 million shares, and the company’s market capitalization rose to about $34.7 billion (roughly KRW 47 trillion). In a single day, it added approximately $8.9 billion (around KRW 12 trillion) in market value.

Recently, several law firms have issued notices inviting investors who purchased CoreWeave shares between March 28 and December 15, 2025, to apply to be lead plaintiffs in a securities fraud class action by March 13, 2026. The suits allege that the company failed to adequately disclose delays in building a major data-center cluster in Denton, Texas, for OpenAI—and that these setbacks wiped out roughly $14 billion (about KRW 19 trillion) in market capitalization.

CoreWeave is an AI-focused cloud provider offering high-performance computing infrastructure powered by Nvidia GPUs. It has secured large-scale, long-term contracts with OpenAI, Meta and others, and is building massive data centers across Texas and beyond. Founded in 2017 as a cryptocurrency-mining operation, the company pivoted to AI cloud infrastructure and, since its March 2025 Nasdaq debut, has pursued aggressive, debt-financed capital investments to fuel rapid growth.
