China’s Hua Hong Pours $2 Billion Into Wuxi Expansion to Meet Surging AI Demand

Hua Hong Semiconductor, China's second-largest contract chipmaker, is investing $2 billion to build a new fabrication plant in Wuxi, China as part of a push to expand capacity as domestic demand for AI-related chips outstrips what the industry can currently produce.

The company disclosed the investment in a filing to the Hong Kong stock exchange this week, confirming plans for a new 12-inch specialty production line which is its third facility in Wuxi, a major chip-manufacturing hub in eastern China. Once fully operational, the expansion is expected to add 55,000 wafers a month to the site's capacity, a roughly 30 per cent increase.

Hua Hong and its Shanghai subsidiary will together supply $2.1 billion of the funding, giving them a controlling 51 per cent stake in the project while entities that are linked to the state will contribute the rest. Total funding for the buildout comes to $4.2 billion once the state capital is factored in, which shows how closely Beijing's industrial-policy apparatus remains tied to the country's chipmaking ambitions.

Higher demand pushes fabs to capacity

The expansion comes as Hua Hong, along with rival SMIC, is running its existing fabs close to or above full capacity. Hua Hong's utilisation rate hit 102.8 per cent in the second quarter, and executives have said orders for certain product lines are running at 1.5 to 2 times available capacity, with some categories booked out through 2027. That squeeze has already pushed foundry prices higher through the first half of the year, with further increases expected into 2027.

The chips are what’s driving the surge, surprisingly; not the cutting;edge AI accelerators themselves - microcontrollers, power-management components, memory and analog chips that support AI servers and data-center infrastructure. As global demand for that category has spiked, Chinese customers have increasingly turned to domestic foundries rather than compete for capacity at Taiwanese or other overseas fabs, a shift that's been building since late 2025.

Domestic production avoids outside limitations

Chinese foundries like Hua Hong and SMIC sit largely in "mature node" territory - chip processes that don't require the most advanced lithography tools the U.S. has restricted export of.

By building out capacity at these nodes rather than chasing the leading edge, Chinese chipmakers can meet a huge and growing share of domestic AI-infrastructure demand without running into the export controls that have throttled access to advanced equipment needed for cutting-edge logic chips.

It's a workaround rather than a breakthrough, but it's a workaround that's proving commercially very effective and one Beijing has clearly decided is worth subsidising.

Whether that capacity keeps up with demand is now the open question. Hua Hong's own executives have described a "secular growth story" running through 2027, with some uncertainty creeping in around 2028, and the timing roughly tracks how long the current wave of AI infrastructure building is expected to last in China and elsewhere.
