零营收但估值超260亿美元？最严重的AI泡沫其实在能源股！

Core Viewpoint - The article highlights a speculative frenzy in the energy sector driven by artificial intelligence (AI), with several energy companies, despite having no revenue, seeing their valuations soar to unprecedented levels, totaling over $45 billion [1][6]. Group 1: Energy Companies and Valuations - Oklo, a nuclear startup supported by OpenAI's CEO Sam Altman, has seen its stock price increase approximately eightfold this year, reaching a market capitalization of $26 billion, making it the largest U.S. public company without revenue in the past 12 months [1]. - Another zero-revenue company, Fermi, had an initial valuation of around $19 billion upon its listing and currently maintains a market cap exceeding $17 billion, with only two other zero-revenue companies historically surpassing this valuation on their listing day [3]. - Other companies in the nuclear sector, such as Nano Nuclear Energy and Terra Innovatum, have also experienced significant market cap increases, with Nano's stock rising over 100% this year and a valuation exceeding $2 billion [7]. Group 2: Market Sentiment and Risks - The speculative wave reflects extreme optimism regarding future energy demands driven by AI, but these energy startups have little room for error, as they lack actual revenue to support their high valuations [6]. - Companies like NuScale Power and Plug Power, which have seen stock price increases of 155% and 90% respectively, still face challenges in achieving profitability before 2030 [8]. - The high valuations of established profitable companies may be driving investors towards these speculative startups, reminiscent of the electric vehicle startups that faced significant downturns after their initial hype [10].
