这种债务与股权的涌入使投资者的资产多元化变得日益困难。由于主动型基金经理人的表现是与广泛的基准指数进行比较，大型指数基金被迫以异常优渥的条件购买新上市的科技股，从而将评估集中度风险的责任转移给资产配置者。Lombard Odier 的 Michael Strobaek 和 Clément Dumur 指出，这迫使聪明的配置者在 AI 生态系统对资金产生强大引力的情况下，自行决定是要持有还是分散投资。
AI 也已演变成一个主要的总体经济驱动因素。虽然联邦准备理事会主席 Kevin Warsh 认为 AI 可能会成为推动降息的去通膨力量，但 Pimco 估计，未来五年内 AI 投资可能会为全球资本支出增加约 14 兆美元（$14tn）。这一庞大金额约占全球经济产出的八分之一（12.5%），此一投资规模足以驱动全球总体经济活动，并可能在未来几年引发显著的市场波动。
AI technology is driving a major shift in capital markets. The recent public listing of Elon Musk's SpaceX, alongside expected trillions of dollars in market capitalization from upcoming listings of OpenAI and Anthropic, is reversing two decades of shrinking US stock listings. Additionally, tech giants like Amazon, Alphabet, and Meta have more than doubled their outstanding debt in recent months to approximately $300 billion ($300bn), causing a shift in the corporate bond market where standard diversification rules are being challenged by this massive issuance.
This influx of debt and equity is making diversification increasingly difficult for investors. Because active managers' performance is benchmarked against broad indices, large index funds are compelled to purchase newly listed tech stocks on generous terms, shifting the responsibility of concentration judgment to allocators. Lombard Odier's Michael Strobaek and Clément Dumur note that this forces intelligent allocators to decide whether to own or diversify, even as the AI ecosystem exerts a strong gravitational pull on funds.
AI has also evolved into a major macroeconomic driver. While Federal Reserve chair Kevin Warsh views AI as a potential disinflationary force that could lead to rate cuts, Pimco estimates that AI investment could add approximately $14 trillion ($14tn) to global capital spending over the next five years. This enormous sum represents roughly one-eighth (12.5%) of global economic output, a scale of investment capable of driving global macroeconomic activity and potentially causing significant market volatility.
