Asia Tech Wire (June 25) -- Fast-fashion giant Shein has secretly filed papers with the UK market regulator for a possible London listing, according to multiple media reports.

If it ultimately comes to fruition, it could be the largest IPO in London in more than a decade, the reports said.

Previously, sources said Shein could have a valuation of nearly £50 billion ($63.3 billion) in the IPO.

However, while Shein is aiming to go public in the second half of the year, there is no guarantee that the company will move forward with a London IPO.
