NVIDIA (NVDA.O) shares fell 14%, pushing market capitalization below $4 trillion.

Saxo Bank chief investment strategist Charu Chanana said in a note that uncertainty over NVIDIA’s leadership could accelerate shifts to alternative suppliers. AMD, Broadcom, Alphabet and Samsung Electronics may benefit, though meaningful market-share gains will take time. A larger risk is disruption to the broader AI ecosystem: higher debt financing, pressure on hyperscalers’ free cash flow and regulatory uncertainty are already testing the sustainability of AI spending. Chanana described this as a test for AI trades rather than their end and said investors should separate firms benefiting from ongoing infrastructure spend from those that can generate sustainable returns from AI adoption.

IDC says China tablet shipments were 6.6 mln units in Q3 2026, down 22.3% YoY. IDC attributed the fall to accelerating cost pressures passed to demand, widening the market correction: consumer demand continued to shrink amid price increases, while the commercial segment normalized after earlier front‑loaded orders, shifting vendor competition and demand mix. Quarterly shipments fell below 7 mln for the first time in 12 quarters, marking the largest single‑quarter decline since Q1 2020 and the market's first double‑digit YoY drop.
