Shein’s IPO collapses to a $26.5B valuation as gray-market shares plunge 10%

Ahead of tomorrow's debut, fast-fashion giant Shein saw its gray-market shares collapse by over 10% on Hong Kong brokerages today, just 24 hours ahead of its official listing on September 1st.

The company's private valuation peaked at roughly $100 billion, but this IPO is debut-pricing at a massively deflated $26.5 billion valuation. It seems the combined pressure of tightening U.S./EU tariff regulations and supply chain scrutiny has completely evaporated institutional enthusiasm.

Shein relies on duty-free exemptions to maintain their low-margin pricing model, how do you see this stock performing over the next quarter? Value play or is the regulatory risk too high?
