- The document values Prosper Marketplace, Inc. at $1.507 billion for its current funding round based on an analysis of the peer-to-peer lending market and Prosper's position within it. - While the peer-to-peer lending market is growing rapidly and expected to reach over $300 billion by 2025, Prosper possesses few competitive advantages that are eroding as more competitors enter the market. - As a result, the analysis only recommends investing in Prosper at or below the current $1.51 billion valuation due to slowing growth and declining margins from increasing competition in the peer-to-peer lending space.
