Tesco's new financial price comparison site was launched by the supermarket giant last week as it moves into a market dominated by confused.com and moneysupermarket.com.
Financial comparison website has been valued at £1bn in advance of the planned share offering on July 31.
The FT reports that Moneysupermarket plans to sell around 40% of the company's shares to pay off debts and release capital. Shares will be priced at between 170p and 210p.
