德银深度报告:真假AI泡沫,究竟谁在裸泳?
美股IPO· 2025-12-13 11:14
德银认为,当前AI热潮并非单一泡沫,而是由估值、投资、技术三重泡沫交织。公开市场巨头估值有盈利支撑,而私营公司估值已极度高企。天量投资 由现金流驱动,非债务扩张,但复杂循环融资与潜在技术瓶颈埋下风险。AI需求强劲且成本骤降,但能源与芯片供应或成最终制约。 站在2025年12月的时间节点,距离ChatGPT发布仅过去三年,市场对于"AI泡沫"的讨论已至沸点。德意志银行认为,当前AI热潮既不是完全的泡沫,也 不是毫无风险,关键在于区分不同类型的"泡沫"。 12月12日,德银在最新研报中创新性地将AI泡沫分为估值泡沫、投资泡沫和技术泡沫三个维度进行分析。 报告称, 公开市场大型科技公司的估值有盈利支撑,投资增长符合趋势且由现金流推动,技术进步仍在持续。真正的风险集中在估值过高的私营公 司、可能失控的循环融资结构,以及潜在的技术瓶颈和供应限制。 估值泡沫:估值分化揭示真实风险所在 德银的核心观点是当前AI热潮并非单一泡沫,而是由三种不同性质的泡沫构成。 在估值维度 ,报告显示希勒周期调整市盈率(Shiller Cyclically Adjusted Price/Earnings ratio)已超过40,接近2000年 ...
