I'm an old-timer, but, back in the day, some loan listings on LC/P would show up as "withdrawn" by borrowers when the platforms (or investors) didn't have enough capital on hand to fund them or when the borrower failed a pre-disbursement ID or income verification - can't remember timeframe specificity of when the platforms pivoted away from individual investors / started using their balance sheet - though do remember some hubbub about that noise in the data, most of which turned out, I believe, to be due to ID/income checking, which happened temporally *after* the loans were "funded" (much markovian state-transition fun, trying to figure those listings out in order to avoid tied up capital in loans which were "unlikely to originate")...
