Alphabet(GOOGL.O)和微软(MSFT.O)在本轮财报季中重申了其资本支出预期，Meta Platforms(META.O) 则上调了其资本支出前景。亚马逊(AMZN.O)）本周虽未给出全年资本支出预测，但确认第一季度支出 为243亿美元，主要用于支持AI服务需求。今年2月，亚马逊曾预计全年支出节奏将达到约1000亿美 元。 综合来看，Meta、亚马逊、Alphabet和微软仍有望在今年合计投入超过3000亿美元，用于AI数据中心及 相关基础设施建设。 从股价反应来看，华尔街似乎对这些支出计划基本满意。 一些分析师认为，即使整体预算收紧，AI仍将是重点。 市场研究公司IDC总裁Crawford Del Prete上个月在特朗普政府关于关税政策反复变动后表示："这确实是 一个极为特殊的情况。"他说，他刚刚与一位信息技术高管谈过，对方正在叫停支出计划。"他们在拖 延，他们在冻结预算。"他说。 一些分析师预计，即使整体IT预算受到挤压，AI支出仍将是优先事项；但也有其他人对此持怀疑态度。 最新财报季后，有一点已经十分明确：大科技公司计划继续大举投资，用庞大的预算推进人工智能数据 中心的建设。 尽管由于对 ...
