According to two sources, Reuters reported that Shein confidentially filed for an IPO with Britain’s markets regulator in early June.

In May, Reuters cited sources reporting that the filing, which would initiate the process for a listing on the London Stock Exchange, comes after the company explored a listing on the Exchange early this year after lawmakers opposed a U.S. listing.

Reuters said the China-founded company was valued at $66 billion in a fundraising round last year.

Shein has reportedly officially updated China’s securities regulator about its change of listing venue, Reuters said, referencing “the sources.”

One source told Reuters that the company has yet to receive approval from the China Securities Regulatory Commission (CSRC).
