CXMT’s mega IPO soars ~470% on debut, underscoring strong demand for China’s home‑grown chips amid liquidity worries
Executive summary: CXMT launched its STAR market IPO and its shares rose approximately 470% on the first day of trading. The debut signals strong market appetite for China’s semiconductor self‑sufficiency, but also raises flags about potential liquidity strain on the STAR board and broader Chinese equity markets.
Who is involved: CXMT (China’s leading DRAM maker), the Shanghai STAR Market, institutional and retail investors, and Chinese regulators overseeing the IPO.
Likely next: Lock‑up shares will become tradable around late October 2026; regulators may monitor STAR liquidity and consider tweaks to IPO size limits; CXMT may use the proceeds to expand fab capacity.
On July 27 2026, China’s second‑largest IPO ever saw CXMT’s shares jump roughly 470% above its offer price in the STAR market debut. The surge reflects investor confidence in the country’s push to replace imported DRAM with domestic supply, even as analysts warn that the massive fundraising could drain liquidity from the STAR‑200 index and exacerbate concerns about a looming credit squeeze on Chinese exchanges.
