Wall Street sinks as Nasdaq falls over 2% on AI cost worries

The Nasdaq, a tech-heavy stock market index, experienced a significant drop of over 2% on Thursday, as growth stocks faltered due to growing concerns surrounding artificial intelligence (AI). The decline in the Nasdaq was primarily driven by disappointing earnings reports from major tech companies Tesla and Meta, which failed to alleviate investor worries about the high costs associated with AI development.

Meta, the social media giant, saw its shares plunge by 5.2% after announcing a new class of non-voting shares aimed at funding its expensive AI initiatives. Despite Meta reporting stronger-than-expected quarterly revenue and sharing optimistic sales forecasts for the fourth quarter, the market reacted negatively to the news, reflecting growing apprehension about the financial implications of AI expansion.

The market's downturn marked a stark contrast to the previous day's rally, which was fueled by positive earnings from SpaceX and Super Micro, two prominent players in the AI sector. However, this initial optimism quickly dissipated as investors began to scrutinize the substantial capital investments required to build AI infrastructure and questioned the timeline for potential returns on such significant expenditures.

The market's decline had a profound impact on various sectors, with the Philadelphia Semiconductor Exchange Index (S&P 500 Semiconductors) facing a potential loss of more than $616 billion in market value. Additionally, the Nasdaq-100, a key index comprising 100 of the largest non-financial companies listed on the Nasdaq Stock Market, was on track to lose nearly $1 trillion in value.

The semiconductor sector, in particular, plummeted by 5.6%, reaching its lowest level since July 29, as investors reassessed the long-term prospects of AI-driven technologies and their potential impact on traditional industries.
