One day after Lending Club’s regulatory approval and site launch, Prosper has closed their site to new loan funding, and announced that they will be seeking regulatory approval for a secondary market. After 2.5 years of continuous operation and $178 million in loans funded, it is odd that Prosper would make such a rash decision. Unfortunately, given the quiet period, it is unlikely that Prosper will reveal any further information about what caused this change.

The full message posted on Prosper’s Blog was:

Prosper has started a process to register, with the appropriate securities authorities, promissory notes that may be offered and sold to lenders through our site in the future.

The registration filing is a necessary step toward making the secondary lending market available to the community. This is something many of you have been asking for, and we believe the liquidity of a secondary market will make Prosper even more vibrant.

Until we complete the registration process, we will not accept new lender registrations or allow new commitments from existing lenders. If you’re an existing lender, your current lender agreements will be unaffected; your existing loans will continue to be serviced; you’ll be able to track and monitor your loans; and you’ll be able to withdraw funds from your Prosper account.

If you’re a borrower with an existing loan, you will continue with your current borrower agreement and be unaffected by the registration process. If you’re a borrower seeking a loan, you will still be able to create a new loan listing, which we will endeavor to fulfill through alternative sources.

A successful registration can take several months, but we assure you we will do our best to move forward as quickly as possible. Until this process is complete, we’re required to be in a quiet period and will be unable to respond to press, blogger or other inquiries about Prosper or the registration filing until it becomes effective.

We apologize for any inconvenience this may cause, and want to thank you in advance for your understanding and support.
