Made.com is reportedly considering a market listing that would value the online furniture retailer at £500mln.
The firm is in talks with banks over strategic options, which include a flotation, selling a stake to a new investor or the sale of the whole group.
It could be valued at £500mln and upwards, potentially close to £1bn, Sky News reported.
The firm was launched in 2010 by Ning Li, Brent Hoberman, Julien Callede and Chloe Macintosh with £2.5mln in funding and made £212mln in sales in 2019.
Hoberman is also one of the co-founders of travel operator Lastminute.com.
Several companies have recently made plans to float in London, including Beckham-backed cannabis firm Cellular Goods and wine seller Virgin Wines, while card retailer Moonpig (LON:MOON) and bootmaker Dr Martens (LON:DOCS) have started trading this month.
