I don't think it is. The subsidiary you are talking about LC Advisers isn't using LC's own capital. It is a vehicle that manages investments from institutional investors.
As LendingClub has grown it has transitioned from a purely P2P model where individuals made the majority of the loans to a whole loan model where banks and other accredited institutional investors make up the majority of the loaned capital. They still have the original platform but their growth isn't coming from Joe off the street it's coming from big banks etc... who see this as a cheaper way to do underwriting.
