AI Data Center Beneficiaries Plummet Ahead of Earnings, 3 Trillion Won in Market Cap Vanishes in a Day

Bloom Energy Corporation (BE), regarded as a beneficiary of AI data-center power demand, tumbled about 7% on the New York Stock Exchange on the 5th, closing around $137. In a single day, its market capitalization declined by approximately $2.2 billion (about KRW 3 trillion), bringing its total market cap to about $32.4 billion (roughly KRW 40 trillion).

Bloom Energy is scheduled to announce its fourth-quarter 2025 financial results and host an earnings call after market close on the 5th, U.S. Eastern Time, according to its public filing. The stock had already dropped nearly 10% the previous day, extending declines into a second session amid profit-taking and valuation concerns for a company that had ridden the rapid growth of AI data centers.

Specializing in on-site power generation systems based on solid oxide fuel cells, Bloom Energy supplies low-carbon electricity to data centers, large utilities, and semiconductor fabs. It recently secured a long-term supply agreement valued at about $2.65 billion with American Electric Power (AEP) and struck an AI data-center partnership with Brookfield worth up to $5 billion—roughly KRW 3.5 trillion and KRW 6.5 trillion, respectively. In its 2026 Data Center Power Report, the company projected that by around 2030, nearly one-third of data centers could fully transition to on-site power, underscoring rising demand amid grid constraints fueled by AI proliferation. Analysts expect continued volatility in the stock based on upcoming earnings and new contract announcements.
