Eaton Corporation shares fell 7.01% to $395.61 on Monday as concerns about a potential slowdown in hyperscale AI investment combined with rising yields and energy costs. Weekend calls by Anthropic CEO Dario Amodei, supported by Sam Altman and Elon Musk, for a voluntary slowdown in frontier-model development raised questions about the pace of data-center expansion. Reports that OpenAI has delayed its public market debut until at least 2027, along with DeepSeek’s V4.1 Flash efficiency update, added to investor concerns that hyperscalers could moderate buildout plans. Eaton supplies switchgear, transformers, uninterruptible power supply systems and liquid-cooling architectures, including those expanded through its acquisition of Boyd Thermal, leaving its Electrical Americas and Electrical Global divisions exposed to near-term capital-spending uncertainty. Broader pressure came from higher Treasury yields ahead of central bank policy meetings later this week and Brent crude rising above $108 per barrel after escalating Middle East tensions, including the reported seizure of key maritime territory near the Bab al-Mandeb Strait by Houthi forces.
