US Stocks Tumble Amid AI Fears and Renewed Tariff Concerns
US equity markets experienced significant declines on Monday, February 23, 2026, as investors grappled with mounting concerns surrounding the potential economic impact of artificial intelligence and a resurgence of protectionist trade policies under President Donald Trump. The Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all closed lower, with the Dow falling below the 50,000 mark.
Market Performance
The Dow Jones Industrial Average dropped 821.91 points, or 1.66%, closing at 48,804.06. The S&P 500 declined by 1.04% to 6,837.75, returning to negative territory for the year 2026. The Nasdaq Composite fell 1.13%, ending the day at 22,627.27.
AI-Driven Tech Sell-Off
The technology sector bore the brunt of the market downturn, fueled by renewed anxieties about the disruptive potential of artificial intelligence. IBM experienced a sharp decline, falling 13% after Anthropic unveiled advanced programming capabilities for its Claude Code product. This sparked fears that established technology companies may struggle to compete with the rapid advancements in AI. Microsoft and CrowdStrike also saw significant losses, declining 3% and nearly 10% respectively. Concerns extended beyond software, impacting sectors like transportation, logistics, commercial real estate, and financial services, as investors assessed the potential for automation and efficiency gains driven by AI.
Research from Citrini Research suggested that the expansion of AI could lead to a 10% unemployment rate, further unsettling Wall Street and contributing to the sell-off in financial stocks. American Express lost 7% and Mastercard declined by approximately 6%.
Flight to Safety and Defensive Stocks
Amid the market turmoil, investors sought refuge in defensive stocks. Walmart and Procter & Gamble saw gains of over 2%, benefiting from their relatively stable profiles during periods of economic uncertainty. Gold also experienced a rally, with spot prices rising more than 2% and futures increasing by over 3%, indicating increased demand for safe-haven assets. Bitcoin, however, fell below $65,000, declining more than 4% as risk aversion took hold.
Trump Announces New Tariffs
Adding to the market’s woes, President Trump announced an increase in global tariffs to 15%, up from the previously announced 10%, with immediate effect. This move followed the Supreme Court’s recent decision to strike down his “reciprocal” tariffs. The President has maintained that he possesses legal authority to implement his trade policies, potentially leading to further legal challenges.
European officials have expressed concerns about the impact of the new tariffs on trade relations with the United States. The European Parliament has paused the ratification process of a recently reached trade agreement with the US. Companies with significant international exposure, such as Nike and Wayfair, experienced further declines in their stock prices.
Looking Ahead
The combination of AI-related disruptions and escalating trade tensions has created a volatile market environment. Analysts anticipate ongoing legal and political debates surrounding the tariff policy throughout the remainder of the year. Investors are bracing for continued uncertainty in 2026, with a prevailing sense of caution on Wall Street.
