Shein, the fast-fashion retailer founded in China, is set to go public next week in Hong Kong after previously considering a London stock market listing. The decision comes after prolonged discussions throughout 2023 and early 2024, during which Shein was courted by UK politicians and regulators eager to attract high-profile international listings to a sluggish domestic market.

The company had initially ruled out a New York initial public offering amid strained US-China relations and increasing scrutiny from American lawmakers over alleged labor practices within Shein’s supply chain in China. London's market emerged as an alternative venue, viewed by Shein’s owners as a viable Western stock exchange option. UK officials and the Financial Conduct Authority (FCA) adopted a relatively accommodating stance toward the company, emphasizing transparent disclosure over concerns related to the company’s global legal risks.

However, the prospect of a London listing was significantly undermined in January 2025 when Shein’s European general counsel appeared before the UK Parliament’s business select committee but declined to provide detailed responses regarding the company’s operational practices. When asked whether Shein sourced cotton from China, the counsel declined to answer, citing lack of authorization to discuss such specifics. This was before questions arose around the use of cotton allegedly produced in the Xinjiang region, an area linked to forced labor concerns involving Uyghur populations.

Despite Shein’s prior commitments to comply with modern slavery laws in multiple jurisdictions, including the US and UK, the committee chair Liam Byrne criticized the company for its evasiveness, characterizing it as bordering on contempt. This episode appeared to contribute to the decision to abandon plans for a London flotation, with speculation that political pressure from Beijing may have also influenced the outcome.

Shein’s valuation has diminished notably since the London discussions began. While early estimates put the company’s worth at approximately £50 billion, the forthcoming Hong Kong IPO is expected to value Shein around $27 billion (approximately £20 billion). This decrease partially reflects challenges related to the company’s business model, particularly its reliance on shipping goods in small parcels from China to exploit tax breaks on low-value imports—so-called "de minimis" thresholds.

The US has already eliminated these exceptions as part of trade measures initiated under the Trump administration, and the European Union plans a phased removal, with the UK targeting elimination by 2029. While Shein has maintained that its model is not dependent on such tax rules, investors appear to treat the issue as material risk, which is reflected in the lower valuation.

Had Shein proceeded with a London listing at the earlier valuation, the subsequent markdown might have led to investor disappointment in the UK market. The eventual decision to pursue a Hong Kong flotation has been described by some observers as sparing London a difficult outcome. The episode underscores the complexities of balancing regulatory openness with oversight, particularly in markets seeking marquee tech and consumer companies amid geopolitical tensions.
