“The S&P 500 reached a new all-time high on Wednesday, climbing to the 6,753-point zone, boosted by a rally in the technology sector following comments from Nvidia CEO Jensen Huang, who highlighted strong and sustained demand for chips linked to artificial intelligence (AI). The milestone reflects investors’ continued appetite for tech companies, which remain at the forefront of the U.S. market’s expansion amid global economic uncertainty.
The enthusiasm surrounding AI remains the main engine behind the stock market’s advance. Major tech firms, led by Nvidia, Microsoft, Alphabet, and Amazon, have seen their valuations surge as expectations grow regarding the benefits of automation and accelerated computing. Huang’s remarks reinforced the perception that the AI revolution is still in its early stages, reigniting optimism across Wall Street.
Huang also surprised markets by expressing interest in investing in xAI, Elon Musk’s artificial intelligence startup, which is seeking to raise $20 billion in funding. This potential link between two of the most influential figures in the tech industry was interpreted as a sign of consolidation within the AI ecosystem, where strategic alliances and access to capital are becoming crucial to maintaining competitiveness.
Despite the tech-driven momentum, the market showed some caution. Investors remain focused on the release of the minutes from the latest Federal Reserve (Fed) meeting, searching for clues about the future path of interest rates. Although inflation has shown signs of moderating, the Fed maintains a cautious tone, mindful of the risks of economic overheating amid the market’s upswing.
The political backdrop also added a layer of uncertainty. The partial shutdown of the U.S. government, which has disrupted the release of official data, has forced analysts to rely on private sources and alternative estimates. This lack of reliable information has created volatility and some mistrust in the markets, especially in sectors sensitive to economic cycles such as consumer goods and manufacturing.
In contrast, Treasury yields remained stable while the dollar edged slightly lower, reflecting a preference for risk assets. Shares of semiconductor and software companies captured most of the buying activity, with notable gains in AMD, Broadcom, and Salesforce, all of which are beneficiaries of renewed interest in the AI and cloud computing sectors.
Meanwhile, some analysts warned of potential overvaluation in tech stocks, similar to previous phases of market exuberance. However, the current environment differs in that AI adoption is already translating into tangible profits, suggesting a more sustained and structural growth cycle than in the past.
In conclusion, the S&P 500’s new record underscores technology’s role as the backbone of modern financial markets. Although risks related to monetary policy, the lack of official data, and political tensions in Washington persist, the momentum generated by artificial intelligence continues to push Wall Street higher. If this trend holds, 2025 could mark a turning point in the full integration of AI into the global economy and the very structure of the stock market.
