The American stock market experienced a significant decline on Thursday, causing the value of major technology companies to drop by hundreds of billions of dollars. Companies related to artificial intelligence (AI) were the hardest hit. The market capitalization of large Nasdaq-100 index companies decreased by $2.5 trillion in a single day, equivalent to approximately 236 trillion Indian rupees.
The main reason cited for this downturn is the fear of increased regulatory pressure on AI companies following the Democrats' victory in the elections. Investors are concerned that oversight of AI company activities may become stricter, especially regarding data center construction, or that the pace of their construction might slow down.
This concern manifested immediately after trading opened on Thursday. According to the news agency Reuters, the Nasdaq Composite index, which includes technology companies, fell by 5.5%. This was the largest single-day drop since the 'Liberation Day' in April 2025. The total market value of the largest Nasdaq-100 companies shrank by $2.5 trillion.
The decline continued into the second day for AI company stocks, which also affected chip manufacturers. The index for these companies plummeted by approximately 12%, reaching its lowest level in over six months. Shares of AI-related CoreWeave also showed a decline of 10%.
The Nasdaq Composite is currently about 12% below its record high from October 6th. When any index falls by 10% or more from a recent peak, it is called a 'correction.' Thus, Nasdaq has reached this stage. Since mid-October until now, there have been five instances of a drop of more than 500 points in Nasdaq. Market experts express anxiety about the slowdown in data center construction. High interest rates are already making it difficult for small AI companies to raise funds, and fears of stricter regulations could exacerbate their difficulties.
Donald Trump also reacted to the stock market decline. He wrote on social media that the market experienced one of the worst days in its history due to the election results, placing the blame on the Democrats. Trump noted that the market drop led to a reduction in people's 401(k) retirement account funds. However, he expressed confidence in America's quick recovery, calling the Democrats 'Dumocrats' in his post.
Currently, the market's primary concern is how strict future rules for AI companies will be and how this will affect data center construction plans. However, it is precisely this fear that triggered the rapid sell-off of AI stocks.
