Chip stocks suffer worst stretch in 16 months as AI fatigue grips the market

Semiconductor shares have just recorded their worst stretch in 16 months, a move that reflects growing investor fatigue with the pace of artificial intelligence spending. The pullback suggests the market is shifting from rewarding AI ambitions broadly to scrutinizing whether those outlays are translating into durable returns.

Attention now turns to Anthropic's investor day, where anticipation is building on Wall Street. The event is shaping up as a test of sentiment: investors appear less patient with heavy AI capital expenditure, and commentary on spending plans, timelines, and monetization may influence how chip and AI-linked names are viewed in the near term.

For observers, the key question is whether this is a pause in a long-running theme or a broader reassessment of AI valuations. Watch how the sector responds around the investor day, and whether chip demand signals from major customers stay intact.
