US stocks experienced a significant boost on Wednesday as markets opened following the Democrats' decisive victory in the midterm elections. The S&P 500 rose by 1.1 percent, while the Dow Jones Industrial Average surged by 1.9 percent, and the Nasdaq Composite also increased by 1.1 percent. This positive market reaction reflects a reduction in political uncertainty that had been weighing on Wall Street, allowing investors to regain confidence in the market's stability.

Despite the overall rise in the stock market, shares of Tesla and SpaceX faced declines. The downturn in these stocks coincided with a broader slide in artificial intelligence stocks, which are now under pressure due to heightened expectations surrounding a Democrat-controlled Congress. This shift in political power is expected to influence regulatory approaches to technology and innovation, particularly in the AI sector, leading to cautious investor sentiment in these areas.S2
