In April, we saw the supply of loan listings with an attractive risk-return tradeoff hit an all time high and approximately double compared to the prior month. At the end of March, the supply of loan listings with an attractive risk-return tradeoff was approximately $5 million; and at the end of April the supply increased to approximately $11 million and has remained at that level into May.
This significant increase in the supply of loan listings with an attractive risk-return tradeoff is attributed to the fact that on April 15 we commenced our business arrangement with WebBank, a Utah-chartered industrial bank. Through our agreement, all loans originated through the Prosper marketplace resulting from listings posted on or after April 15, 2008 are made by WebBank under its bank charter. Prosper provides services to WebBank in connection with the origination of such loans and Prosper services loans made to Prosper borrowers on behalf of registered Prosper lenders who purchase such loans. In effect, this partnership opened the platform to more borrowers, who may have previously been constrained by low state rate caps.
Also in April, we saw the supply of prime borrower listings hit an all time high, accounting for nearly half of all loan listings in terms of dollars requested. Prime borrower originations also reached its record level of 43% of funded loans.
Currently, the significant increased supply of quality listings is providing more attractive bidding opportunities, which is making it easier for lenders to efficiently deploy more money onto the platform.
