Top Analyst Warns AI Slowdown Could ‘Crimp’ Microsoft, Alphabet, Meta, Amazon and Other Earnings — S&P 500 Rally Faces New Threat

Citigroup's Stuart Kaiser warns that growing AI safety concerns could slow AI development, negatively impacting corporate earnings, particularly for major tech companies. This, combined with other macro headwinds, poses a new threat to the S&P 500 rally, suggesting a challenging period for equities.

Citigroup, through Stuart Kaiser, has issued a cautionary note regarding the potential for an AI development slowdown due to safety concerns. This slowdown could 'crimp' earnings-per-share revisions for major tech companies heavily invested in AI, such as Microsoft, Alphabet, Meta, and Amazon. This development, coupled with rising bond yields, surging oil prices, and upcoming midterm elections, creates significant cross-asset headwinds for the broader stock market, particularly the S&P 500. Short-term, this suggests increased volatility and a potential pullback, making it harder for the market to re-engage. Long-term, the impact depends on the actual extent of AI regulation and its effect on innovation and corporate profitability, posing a key risk for traders betting on continued AI-driven growth.
