在季度业绩显示，对大型科技公司 Big Tech 的 AI 建设热潮的投资人情绪有所改善，因为大量投入资料中心和运算能力的回报似乎开始浮现。Alphabet、Amazon、Meta 和 Microsoft 已经几个月来一直面临资本支出上升的审视，但本周的财报暗示成长轨迹更高，云端业务表现更强、且利润率优于预期，帮助安抚了一些疑虑。文章将这一时刻描述为一项考验：AI 基础设施支出最终能否转化为客户愿意付费的高端产品与服务。
最明显的证据来自现金流和云端成长。Alphabet、Amazon、Meta 和 Microsoft 的合计自由现金流在最新一季降至 220 亿美元，约为一年前的一半，但这被合计营运现金流近三分之一的上升所抵消，达到 360 亿美元，使这一群体未陷入负现金流状态。Alphabet 的表现优于预期，AI 驱动的搜寻和云端收入成长较前一季加速 15 个百分点，达到 63%；Microsoft 和 Amazon 也都优于预期，而 Alphabet、Amazon 和 Microsoft 分别报告营业利益率出现意外强劲改善。Microsoft 表示 Copilot 使用者增加了 1/3，而此前它曾说，只有约 3% 付费生产力工具客户在为 Copilot 付费。
这些涨幅伴随著重要但。股票价格在前一个月已经反弹，Microsoft 上涨 16%，Amazon 上涨 25%，但资本支出仍在攀升，最终可能更沉重地压抑获利。Meta 的股价在警告支出将更高后下跌，其营业利润率下滑了近 1 个百分点，而 Google 的 CFO 表示，随著投资激增开始反映到损益表上，折旧将大幅跳升。尽管 AI agents、更便宜的工程，以及按使用量定价正在改善经济效益，文章警告说，这些好处仍处于早期阶段，成本负担尚未完全显现，而且科技员工的工作保障可能变得不那么确定，而不是更确定。
Investor sentiment around Big Tech’s AI buildout improved after quarterly results suggested that the payoff from heavy spending on data centres and computing power may be starting to emerge. Alphabet, Amazon, Meta and Microsoft had spent months facing scrutiny over rising capital expenditure, but this week’s earnings hinted at a higher growth trajectory, with stronger cloud performance and better-than-expected margins helping calm some worries. The article frames the moment as a test of whether AI infrastructure spending can ultimately translate into premium products and services that customers will pay for.
The clearest evidence came from cash flow and cloud growth. Combined free cash flow for Alphabet, Amazon, Meta and Microsoft fell to $22bn in the latest quarter, about half the level of a year earlier, but that was offset by a nearly one-third rise in combined operating cash flow, or $36bn, which kept the group out of negative cash flow territory. Alphabet beat forecasts, with AI-driven search and cloud revenue growth accelerating by 15 percentage points from the previous quarter to 63%; Microsoft and Amazon also beat expectations, and Alphabet, Amazon and Microsoft each reported an unexpectedly strong improvement in operating profit margins. Microsoft said Copilot users rose by 1/3, while earlier it had said only about 3% of paying productivity-tool customers were paying for Copilot.
The gains came with important caveats. Stock prices had already rebounded over the prior month, rising 16% for Microsoft and 25% for Amazon, but capital spending is still climbing and may eventually weigh more heavily on profits. Meta’s shares fell after it warned of higher spending, its operating margin slipped by nearly 1 point, and Google’s CFO said depreciation is set to jump as the investment surge starts to hit income statements. Even as AI agents, cheaper engineering, and usage-based pricing improve the economics, the article warns that the benefits are still early, the cost burden is not fully visible yet, and job security for tech workers may become less certain rather than more.
