Quanta Services (PWR) is sinking 18% today after Chinese start-up DeepSeek reportedly unveiled AI models that were produced using old chips and much less computing power than the AI offerings of OpenAI and Meta (META). However, DeepSeek’s models are at least as proficient as those of OpenAI and Meta, according to multiple reports. PWR designs and builds electric power infrastructure projects and renewable energy systems. Why DeepSeek’s News Is Related to PWR The Chinese tech firm reportedly used about 50,000 of Nvidia’s (NVDA) H100 chips, unveiled back in 2022, to develop its AI models. This news is leading to speculation that fewer of Nvidia’s latest, power-hungry chips will be utilized to create AI in the future, while U.S. data centers may not expand as rapidly as previously thought. Rethinking Electricity Demand It was previously believed that electricity production had to climb a great deal to power both chip manufacturing and data centers. But given the doubts that have now arisen about the demand for chips and the proliferation of data centers going forward, the Street is worried that there will be much less need than previously expected for electricity over the long term. As a result, PWR is tumbling today. While we acknowledge the potential of PWR, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns, and doing so within a shorter time frame.
