ChangXin Memory Technologies Inc.: ChangXin Memory Technologies Inc. conducted a mega IPO on Shanghai’s STAR Market, priced at 8.66 yuan per share. It recorded the highest retail allotment rate since early 2026, at about 47 basis points. Fundraising exceeded its 29.5 billion yuan target, adding roughly 30 billion yuan. Over 9.4 million retail accounts placed valid orders.

China Resources New Energy: China Resources New Energy debuted on July 2, recording an IPO retail allotment rate of about 15 basis points. This was higher than most A-share listings in 2026, which typically fell below 5 basis points, but lower than ChangXin Memory Technologies’ rate.

China Merchants Securities Co. Ltd.: According to the article, China Merchants Securities Co. Ltd. commented on the market impact of mega IPOs, stating that major indexes typically turn negative in the weeks after large listings.

GF Securities Co. Ltd.: GF Securities Co. Ltd. noted that market pullbacks following mega IPOs, like ChangXin Memory's, tend to be milder in bull markets when liquidity is more abundant. This observation was made in the context of ChangXin's large listing on Shanghai's STAR Market.

Semiconductor Manufacturing International Corp.: Semiconductor Manufacturing International Corp. (SMIC), China's largest chip foundry, went public on Shanghai's STAR Market in 2020.
