Shares of semiconductor companies tumbled Tuesday after a report said OpenAI failed to meet internal targets for weekly users and revenue, a development investors interpreted as a potential warning sign for demand for AI-focused computing capacity. Nvidia (NASDAQ:NVDA) led the pullback, slipping about 3% as selling spread across the sector.
Other chipmakers saw deeper declines: Advanced Micro Devices (NASDAQ:AMD) fell 6%, Arm Holdings (NASDAQ:ARM) slid 8%, Broadcom (NASDAQ:AVGO) dropped 5%, Intel (NASDAQ:INTC) lost 4%, Micron (NASDAQ:MU) was down 4%, and Applied Materials (NASDAQ:AMAT) declined 3.4%.
The market reaction followed reporting that OpenAI missed several monthly sales targets in 2026, with those shortfalls occurring as rival Anthropic reportedly made gains in coding and enterprise markets. The coverage cited people familiar with the situation who said the company also recently missed its own objectives for new users and revenue, raising internal doubts about the sustainability of heavy spending on data-center infrastructure.
According to the reporting, Chief Financial Officer Sarah Friar expressed concern to other company leaders that OpenAI could struggle to fund future computing contracts if revenue does not grow at a pace sufficient to support those expenditures. At the same time, board members have increased scrutiny of the company's data-center commitments and questioned Chief Executive Sam Altman’s push to secure additional computing power amid a reported business slowdown.
The story also noted a shift in market perceptions that began last fall after competing models from Alphabet and Anthropic received positive reception. Those product updates - from rivals targeting both consumer and business users - have been associated with intermittent selloffs in stocks viewed as proxies for OpenAI, according to the reporting.
Investors are said to be vigilant for clear signs that technology companies remain on track with previously announced capital expenditure plans to expand AI infrastructure. In response to the reporting, Altman and Friar issued a joint statement calling suggestions that they are at odds or retreating from efforts to secure new computing resources "ridiculous."
The developments underline investor sensitivity to demand signals for AI compute and the potential for company-level execution issues to ripple through related hardware suppliers. Market participants will likely watch for additional confirmation about enterprise adoption trends and corporate capital spending plans tied to AI infrastructure.
