The S&P 500 index has increasingly appeared to function as a concentrated investment in artificial intelligence (AI). The massive capital flowing into data centers, advanced chips, power infrastructure, and sophisticated AI models has generated concern among market observers regarding the stability of the market. In response to this rapid expenditure, a query was posed to ChatGPT regarding whether the current AI-driven enthusiasm signaled a bubble, potentially leading to a 50% drop in the S&P 500.
ChatGPT’s Assessment of Market Stability
The chatbot acknowledged the possibility of a significant decline, stating, “Yes, the S&P 500 could crash 50%. But that doesn’t mean it will.” Despite the caution, the AI highlighted several factors that warrant investor concern. According to the analysis, major US technology companies, including Google, Amazon, Microsoft, and Meta, have collectively committed over $1.1 trillion in capital expenditure since the AI boom began. Furthermore, the figure for planned spending in 2026 alone is estimated at approximately $745 billion.
Analysts noted that the market concentration presents a systemic risk. Currently, US technology stocks constitute nearly 40% of the S&P 500, with some estimates raising this figure to 50% when related industries are included, suggesting the broader market remains vulnerable.
Bubble Indicators and Market Resilience
When addressing the nature of the bubble, ChatGPT noted that a “classic bubble is built on excitement, speculation and companies that don’t make any money. AI doesn’t quite fit that description.” The AI also pointed out that the current market activity is different from the dotcom bubble, where companies often lacked substantial operational infrastructure. However, the model cautioned that valuations could still become excessive. It emphasized that increased money flow into AI demands equally spectacular returns to justify the investment, and warned that external pressures such as rising inflation and interest rates could trigger a market correction. Ultimately, the chatbot advised that even if AI continues to dominate, there will inevitably be disparities, resulting in both major gains and significant losses among the leading tech companies.
Examining Diversification: The FTSE 100 Alternative
Given the heavy exposure to US technology stocks, some investors are turning attention toward other indexes. As an alternative, some observers are looking closely at shares within the FTSE 100. For example, NatWest Group (LSE: NWG) was cited as a company exhibiting strong financial metrics relative to US tech giants. The company’s shares reportedly increased by 216% over a five-year period and gained 30% over the last 12 months, complemented by generous dividend payments.
Financial data for NatWest Group indicated that its Q2 results (concluding July 31) showed operating profit rising 29% to £2.3 billion, surpassing the expected £2 billion. The bank maintains a solid financial standing, evidenced by a CET1 ratio of 13.2% and a price-to-earnings ratio of 9.98, a metric suggested to offer better value compared to many US technology leaders. Furthermore, the bank’s trailing yield currently stands at 4.8%, and its profitability could potentially increase if rising interest rates allow it to widen its net interest margins.
For those concerned about the risks associated with an AI bubble, the analysis suggests that companies like NatWest may offer a more stable avenue for long-term wealth accumulation, irrespective of the future trajectory of the technology sector.
