CXMT

CXMT, China’s top DRAM producer, is pursuing a historic Shanghai IPO backed by roughly $8.6B in pre-IPO funding, while expanding capacity toward 350k DRAM wafers/month and pursuing HBMs, all within a heavy regulatory backdrop and potential price disruption in memory markets.

HBM memory is scaling to multi-layer stacks with high capacities (HBM4E up to ~1 TB per GPU) and complex packaging, while regulatory headwinds and China subsidies are shaping supply dynamics.

Huawei’s Ascend ramp hinges on foreign die banks and HBM imports; domestic capacity could scale, but export controls and HBM supply constraints are the critical near-term bottlenecks.
