曾经风光无限的"AI股王"英伟达，如今股价遭遇断崖式下跌，8000亿美元市值凭空蒸发，投资者纷纷用 脚投票，就连背后的资本大佬也集体跑路。 这波暴跌来得又快又猛，让整个市场都始料未及，毕竟此前英伟达还靠着AI风口一路高歌，成为全球 投资者追捧的香饽饽。 曾经的AI神话为何突然失宠？这8000亿市值蒸发，是AI风口退潮还是另有隐情？这场资本狂欢的急刹 车，背后藏着的行业变化，可能比我们想象中更关键。 市值雪崩 科技行业历来信奉"预期先行于业绩"，但当预期被推到脱离现实的高度，泡沫的破裂只是时间问题。 英伟达的崛起堪称教科书式的赛道红利捕获，AI算力需求的爆发式增长，让其GPU芯片成为无可替代 的核心硬件，股价也随之承载了太多超出业务本身的想象空间。 从被奉为"AI时代终极赢家"到27天内市值蒸发近3500亿美元，这样的剧烈震荡看似突然，实则早已埋下 伏笔。 黄仁勋此前在内部会议中坦言的"无赢局面"，与其说是巨头的审慎，不如说是对行业潜规则的清醒认 知。 在科技领域，单一赛道依赖从来都是高风险游戏，当一家公司的估值完全绑定某个风口，任何细微的风 吹草动都可能引发市场的过度反应。 就像曾经的互联网泡沫、新能源造车热 ...
