Citi Wealth reports that the AI investment cycle faces challenges from rising interest rates, regulatory pressure, and increased infrastructure costs. Despite these concerns, the bank highlights sustained demand for semiconductors and growth in AI-related exports from South Korea and Taiwan as positive indicators.

The bank maintains a preference for diversified semiconductor holdings and hyperscalers, citing their vertical integration in LLMs and data centers as a competitive advantage. Citi Wealth views these sectors as key pillars for its U.S. large-cap strategy.
