Shares in Chinese companies critical to AI infrastructure surged in 2025, with CATL up 45% and Sungrow up 130%, as exports boost margins despite Trump's tariffs
Companies such as battery maker CATL earn big margins on export sales despite US tariffs — Shares in Chinese makers of batteries …
Context & Ripple Effects
The rally sits alongside a broader Chinese push to compete in AI-adjacent industrial domains, not only model development; related coverage described increased focus on EVs and robotics as strategic AI-adjacent sectors.
It also complements evidence that AI demand is reaching domestic hardware supply chains, including record 2025 revenue at Chinese semiconductor companies tied to AI demand and self-sufficiency efforts. CATL and Sungrow show that batteries and power equipment can be part of that same infrastructure investment narrative.
First-order effects
- CATL and Sungrow receive an immediate market-value re-rating as investors price export profitability and AI-infrastructure relevance into their shares.
- For CATL, higher-margin export sales cushion the commercial impact of US tariffs; Sungrow’s sharper share rise signals particularly strong investor confidence in its exposure to the theme.
Second-order effects
- The gains broaden investor attention from chips and compute into the power, storage and grid-facing equipment needed to support AI infrastructure, reinforcing the industrial-domain competition around AI.
- Other Chinese suppliers with credible export or infrastructure exposure face pressure to demonstrate comparable margin resilience and AI-linked demand, while buyers become more exposed to this supply base.
Third-order effects
- If export margins remain resilient, trade barriers may reshape destinations and supply chains more than they prevent Chinese infrastructure suppliers from participating in AI build-outs.
- The pattern points to an AI infrastructure market in which power hardware, energy storage and manufacturing capacity are valued alongside semiconductors—though sustained demand and tariff policy remain key constraints.
The trend: AI investment is transmitting beyond chips into the energy and industrial supply chains that make large-scale computing deployable.
