China Chipmakers' Profits Surge 620% on AI Boom, Self-Sufficiency Drive

Chinese semiconductor firms' aggregate net profit jumped 620% YoY in H1 2026, with revenue up 68%, per Wind data cited by Nikkei Asia. The surge is driven by AI demand and Beijing's self-sufficiency campaign, with CXMT and SMIC leading. This signals accelerating domestic substitution in China's chip sector, though sustainability depends on continued AI capex and export-control impacts.
