China's AI Trade Rewards Exporters, Punishes Local Champions

Chinese technology stocks with the biggest overseas revenue exposure have returned 36% this year — four times the 9% delivered by peers dependent on domestic sales, according to a Bloomberg gauge tracking 30 companies.

A separate Bloomberg measure of the export-oriented firms' outperformance over locally focused rivals is on course for its strongest-ever reading this year. The gap is the clearest sign yet that China's push for global AI supremacy is enriching companies that supply the rest of the world, while fierce competition bleeds their domestically focused peers.

The contrasting fortunes stem partly from Beijing's ambition to build its own AI ecosystem. That self-sufficiency campaign has triggered intense local competition and a vicious price war, eroding profit margins across sectors from chips to robotics. Export-oriented Chinese companies, by contrast, have thrived on surging global demand for AI infrastructure such as data centers.

"Domestic competition is tough no matter what industry. That's the major concern," said Elinor Leung, managing director of Asia telecom and internet research at CLSA Ltd. "If you can sell internationally, the margin is much higher."

Two of the biggest winners of China's AI export boom are optical component makers Zhongji Innolight Co. and Eoptolink Technology Inc. Both derive more than 90% of their revenues overseas. Both stocks have rallied about 50% this year.

The outlook for global AI spending is fueling the gains. Nvidia Corp. Chief Executive Officer Jensen Huang recently said he expects the company to sell twice as many chips in the coming year. The initial success of Meta Platforms Inc.'s new AI agent offers further evidence that demand for semiconductors and computing power will likely stay robust.

Positioning data backs the trend. Many emerging-market funds remain underexposed to China's localization trade and favor exporters leveraged to the US AI capital expenditure cycle, Bank of America strategists wrote in a note last week.

The future of China's AI industry returns to the spotlight this week ahead of a closely watched summit between President Donald Trump and his counterpart Xi Jinping. Investors will watch whether the two countries can put guardrails around the disruptive technology amid a heated race for global dominance.

For portfolio managers, the message from this year's numbers is blunt: the profitable side of China's AI story currently runs through Nevada data centers and Silicon Valley capex budgets, not through the battlefield of Beijing's subsidized home market. Unless the domestic price war eases, the exporter-versus-local gap could widen further.
