Farfetch, the London-based online fashion retailer, is set to list its shares in New York in a deal which is expected to value the company at as much as £4 billion.

Farfetch, backed by Chinese e-commerce firm JD.com is an online fashion business which sells high-end clothing online. It connects users with more than 700 brands and boutiques globally, with brands including Gucci and Prada. Launched in 2007, it ships products to more than 190 countries.

Documents filed with the US Securities and Exchange Commission on Monday set out details of the company’s plan to go public with the ticker symbol “FTCH”. The company has filed for a $100m (£78.3m) public listing but it is likely that this figure is a placeholder that may change closer to the flotation.

The company did not disclose its valuation in the filing, but it has reportedly been targeting a valuation approaching $5bn (£4 billion).

Farfetch’s filing shows that the business had 935,000 active customers at the end of last year, up 43pc from the previous year.
