AI Correction Leads the Downside Risks AI回调领跌下行风险

The scale of recent AI spending helps explain the concern. Capital expenditures by Amazon, Google, Meta, Microsoft, and Oracle reached $412 billion in 2025, equivalent to
1.3%
of U.S. GDP. 近期AI支出的规模有助于解释这种担忧。亚马逊、谷歌、Meta、微软和甲骨文的资本支出在2025年达到4120亿美元，相当于美国GDP的1.3%。
At that scale, AI spending is no longer just a technology-sector story. A slowdown in data centers, computing equipment, and related infrastructure could reduce business investment and weigh on economic growth. 在这样的规模下，AI支出已不再只是科技行业的故事。数据中心、计算设备和相关基础设施的放缓可能会减少企业投资，并拖累经济增长。
The remaining risks largely point to higher costs. Geopolitical escalation ranks second at 47%, while higher
energy prices
(35%) could squeeze household budgets and business margins. Rate hikes (29%) would make mortgages, loans, and business investment more expensive. 其余风险主要指向成本上升。地缘政治升级以47%的比例排在第二位，而能源价格上涨（35%）可能挤压家庭预算和企业利润。加息（29%）将使抵押贷款、贷款和企业投资变得更加昂贵。
AI Also Tops the Economic Upside AI同样领跑经济上行风险
Despite leading the downside ranking, AI also represents economists’ biggest potential source of upside for the U.S. economy. 尽管在下行风险排名中居首，AI同时也代表着经济学家眼中美国经济最大的潜在上行来源。

The economic bet is that today’s enormous AI investments eventually translate into higher productivity. In the meantime, spending on AI infrastructure is supporting business investment and economic activity. 经济上的赌注是，今天庞大的AI投资最终会转化为更高的生产率。与此同时，AI基础设施支出正在支撑企业投资和经济活动。
Tech investment has accounted for
25%
of real U.S. GDP growth since 2023, with its contribution accelerating sharply through early 2026. 自2023年以来，科技投资已占美国实际GDP增长的25%，其贡献在2026年初急剧加速。
For Americans, the other upside scenarios would hit closer to home. Lower inflation and energy prices would leave households with more money to spend elsewhere, while strong employment would support incomes and lower rates would make mortgages and other borrowing cheaper. 对美国人来说，其他上行情景将更贴近日常生活。通胀和能源价格下降将使家庭有更多钱用于其他支出，而就业强劲将支撑收入，利率下降将使抵押贷款和其他借贷更便宜。
The U.S. Economy’s Growing Bet on AI 美国经济对AI日益加大的押注
Taken together, the rankings highlight how important
AI investment
has become to the 2026 economic outlook. 综合来看，这些排名凸显了AI投资对2026年经济前景已变得多么重要。
If the boom continues and delivers broader productivity gains, it could remain an important engine of growth. If spending reverses sharply, however, the same investment supporting the economy today could become a source of weakness. 如果这一繁荣持续并带来更广泛的生产率提升，它可能仍是重要的增长引擎。然而，如果支出急剧逆转，今天支撑经济的同一投资可能成为疲软之源。
