AI development slowdown poses a systemic risk to market earnings and stock valuations
Executive summary: Citigroup warned that the stock market's recent upward trajectory is heavily driven by AI-related progress, creating a risk of sudden correction if model development plateaus. If AI progress slows, the earnings revisions that have fueled market gains may reverse, potentially leading to a significant market pullback.
Who is involved: Citigroup, Wall Street analysts, and the broader technology and equity markets.
Likely next: Monitoring of upcoming quarterly earnings reports from major AI and semiconductor companies for signs of decelerating growth or lowered guidance.
Citigroup has issued a warning regarding the high concentration of recent stock market gains in artificial intelligence.
