You are assuming that borrowers are waiting 12 days for their loans to be funded, issued and funds sent to borrower. It is possible that LC already approved and issued the loan, and sent funds to the borrower. And, now offering the loan on its platform to retail and institutional investors. Think of the process as two distinct parts: first part - loan applied and funds issued to borrower, and second part - loan fractionalized and corresponding notes being issued to investors (fractionalization, reverse of securitization).
