AI capex shifts trigger broad US tech stock selloff
TechNews reported that Tesla cut its 2026 capital expenditure forecast from more than $25 billion to about $20 billion, while Meta raised the lower bound of its full-year forecast from $130 billion to $135 billion and kept the upper bound at $145 billion. Meta reported third-quarter revenue of $64.6 billion, up 26% year over year, but free cash flow was negative $212 million amid large infrastructure investments; its shares fell 7% as investors questioned AI spending and financing. The selloff spread across major technology and semiconductor stocks, with Nvidia down 4.4%, AMD and Micron falling 6.26% to 8.1%, and SpaceX dropping more than 9% after announcing additional AI investment.
The contrasting capex decisions from Tesla and Meta showed how sharply investors were scrutinizing AI infrastructure spending, cash generation and returns across the technology sector.


美股市場對人工智慧(AI)榮景的疑慮加劇,週四清晨盤前半導體與科技股遭遇顯著拋售潮,主因科技大廠在資本支出上釋出截然相反的訊號,包括特斯拉(Tesla)大幅調降資本支出預測引發成長疑慮,而 Meta 則上調支出下限,引發市場對投資回報的擔憂。
特斯拉將 2026 年資本支出預測從原先的 250 億美元以上,大幅調降至約 200 億美元。儘管其單季資本支出為 47.3 億美元且遠低於分析師預期,協助將單季自由現金流推升至 15.3 億美元,但資本支出的縮減同時引發市場對其 Robotaxi、機器人及 AI 基礎設施擴張步調的質疑。
