Stock price appreciation in AI-related companies added an estimated $180 billion to consumer spending over the past year through wealth effects, according to JPMorgan Chase analysis.

The White House is discussing whether to allow Nvidia to export H200 AI chips to China, Bloomberg reported. The H200 offers greater performance than the currently permitted H20 model but remains based on older Hopper architecture, while the advanced Blackwell series stays banned. Treasury Secretary Scott Bessent suggested advanced chips might gain approval once superseded by newer technology, even as Congress prepares legislation to block all advanced chip exports to China.

Constrained capacity investment, supply chain shifts, and Nvidia's pivot to LPDDR technology have triggered a memory supercycle. TrendForce projects Q4 pricing will rise 75% year-over-year. DDR4 and DDR5 module costs have surged 130–180% over 18 months, data show.
