NEW YORK — Economic commentator Scott Galloway warned on Wednesday that the U.S. stock market faces a significant risk of crashing within the next two years, citing excessive investment in artificial intelligence and inflated valuations within the S&P 500.

Galloway, a prominent business professor and author, stated that the current market trajectory is unsustainable. He highlighted that approximately 40% of the S&P 500 index is now tied to businesses focused on artificial intelligence, creating a concentration of risk that could trigger a severe downturn.

The warning comes as the technology sector continues to dominate market performance. Galloway argued that the rapid surge in AI-related stocks has detached valuations from underlying fundamentals. He suggested that the market is pricing in perfection for AI companies, leaving little room for error or missed earnings targets.

"We are seeing a bubble forming," Galloway said during a recent appearance. "The concentration of capital in AI is unprecedented, and when the sentiment shifts, the correction will be sharp."

The S&P 500 has reached record highs in recent months, driven largely by mega-cap technology firms. However, Galloway contends that this rally is built on shaky ground. He pointed to historical precedents where overvaluation in specific sectors led to broad market corrections.

Investors have reacted with mixed responses to the warning. While some analysts agree that valuations are stretched, others argue that AI represents a genuine productivity revolution that justifies the current premiums. Market data shows that trading volumes remain robust, suggesting continued confidence among institutional and retail investors.

The potential impact of a crash would be widespread. A significant drop in the S&P 500 could erode retirement savings, reduce consumer spending, and slow economic growth. Galloway noted that the interconnectedness of the modern economy means a downturn in the tech sector could quickly spread to other industries.

Regulators have not yet issued formal warnings regarding AI valuations, though the Securities and Exchange Commission has increased scrutiny on disclosure practices for AI-related investments. The Federal Reserve has also signaled concern over asset bubbles, though it has not taken specific action to curb the rally.

As of Wednesday, the S&P 500 remained near its peak, with no immediate signs of a correction. However, Galloway's timeline suggests that the window for a potential crash extends through 2026. Investors are left to decide whether to adjust their portfolios or maintain their current positions.

The debate over the sustainability of the AI boom continues. While Galloway's warning highlights the risks, the broader market remains optimistic about the long-term potential of artificial intelligence. Whether the current valuations can be sustained or if a correction is imminent remains an open question as the market navigates the next two years.
