On June 23, Goldman Sachs strategists warned that the AI market has become like a stretched rubber band, and the market's ongoing disregard for negative signals will eventually reach a critical point. Once any major tech giant is the first to cut AI spending, the valuation logic of the entire AI sector will face a comprehensive restructuring.

He specifically highlighted an increasingly widening structural divergence: while hyperscale cloud providers continue to ramp up spending commitments, their stock prices have consistently underperformed the market; meanwhile, AI hardware stocks, represented by Nvidia and TSMC, have risen against the trend. This divergence itself is a signal of market pricing distortion.
