Despite facing multiple lawsuits and government scrutiny in the US, Shein has experienced a remarkable surge in sales volume and profits during the first half of 2023, reaching an all-time high, revealed by CNBC. 

Tang's letter to CNBC mentioned that the company achieved the highest first-half net profit in its history, a significant improvement compared to nearly breaking even during the same period in 2022. He emphasized that their consistent momentum in the US reinforces their leading position in the market. 

The company, rumored to be considering a public listing in the US later this year, has been diversifying its offerings from affordable fashion to include more premium goods and transitioning to a marketplace model. In May, it was valued at $66 billion, a third lower than a previous fundraising round, and its sales reached an impressive $23 billion last year. 

Shein's expansion has not been limited to the US. In Brazil, its marketplace now boasts 6,000 active sellers and tripled the value of goods sold since the beginning of the year, reaching nearly $100 million. 

The company has also announced plans to launch marketplaces in Mexico, Germany, Spain, France, and Italy. The company's growth is notable, given the challenges it faces, including accusations from US lawmakers of lacking supply chain transparency, fierce competition in the market, and being embroiled in court battles with Temu, another Chinese-owned e-commerce operator. 

Shein has been actively recruiting Amazon sellers and denying allegations made by Temu, stating that they have not pressured manufacturers or spread false information about their competitor.
