Chinese semiconductor companies like SMIC reported record 2025 revenue, driven by AI demand and China's self-sufficiency push as a result of US restrictions
Context & Ripple Effects
SMIC’s latest results extend a longer expansion cycle: it previously reported record 2021 revenue while adding capacity under sanctions, then faced a period in which revenue growth coexisted with pressure on profit. The current performance suggests domestic demand and localization investment are sustaining that buildout rather than producing a one-off rebound.
China’s chip push has also been framed around reducing reliance on U.S. manufacturing tools, while investors had already priced in an expected policy tailwind for SMIC. The company’s move to fully acquire its 12-inch-wafer unit gives that strategy a more integrated operating base.
First-order effects
- SMIC and peer Chinese foundries gain revenue support from AI-related chip demand and the domestic self-sufficiency drive; SMIC says second-quarter momentum could improve, although its higher operating expenses are constraining the conversion of sales into profit.
- Taking full ownership of SMNC consolidates control of a 12-inch-wafer business inside SMIC, making that capacity and its investment decisions directly managed rather than shared with a minority owner.
Second-order effects
- Chinese customers seeking more localized chip supply have a stronger incentive to place business with domestic fabs, reinforcing the demand channel behind SMIC’s recent record revenue growth among Chinese chipmakers.
- Rising operating expenses and the cost of consolidating SMNC increase the importance of utilization and product mix: revenue growth alone will not resolve profitability pressure, as shown by an earlier quarter of strong sales growth but lower net profit.
Third-order effects
- If AI demand and policy-backed localization continue together, China’s semiconductor supply chain could become more vertically integrated and less dependent on foreign inputs—an objective already visible in the push to cut reliance on U.S. chipmaking tools.
- That trajectory makes mature-node and domestic-foundry capacity a more strategic industrial asset, while export controls and related scrutiny can continue to shape which equipment, customers, and markets are accessible.
The trend: This is one data point in the convergence of AI infrastructure demand and strategic semiconductor localization, with national supply resilience becoming a driver of foundry investment alongside commercial chip cycles.
