The online retailer is expected to price its shares at HK$48.56, near the midpoint of its HK$47.60 to HK$49.50 marketed range. The offering is expected to raise about $1.7 billion, according to people familiar with the transaction cited by Reuters.

The valuation is considerably below Shein's previous private-market peaks. Reuters reported that the IPO values the company at roughly one-quarter of its nearly $100 billion valuation in 2022 and well below the $66 billion valuation reached during a 2023 fundraising round.

That repricing makes the listing more than a conventional capital-raising exercise. It provides a public-market assessment of whether Shein's highly scalable, digitally driven fashion model can continue producing growth as the cost of operating globally rises.

Shein, headquartered in Singapore and founded in China, sells low-priced clothing across roughly 160 countries. Its model has relied on rapid product turnover, extensive supplier networks and direct-to-consumer digital distribution. However, the company has faced regulatory and commercial challenges in key US and European markets.

Investor appetite is already emerging as a central issue. The overall IPO book was fully covered, but retail demand was described as less robust, while analysts have questioned Shein's growth prospects amid rising costs and intensifying online competition.

The listing could therefore become an important reference point for the wider fashion industry. A successful debut would strengthen the case for digitally native retailers seeking public capital, while a weak reception could reinforce investor concerns about the sustainability of ultra-low-cost fashion models.

For labour markets and supply chains, Shein's public-market transition may also increase scrutiny of sourcing practices, production networks and operating standards. Greater disclosure requirements associated with being publicly listed could expose investors to more detailed information about how the business manages those risks.

What to watch: institutional subscription levels, retail demand, the first trading session and whether the public valuation changes expectations for fast-fashion companies.
