Timing and a failed transfer

A pending bank deposit is usually a transfer still clearing: Polymarket US allows 3 to 4 business days for it to fully clear. If a transfer fails, its troubleshooting page gives the cause as incorrect bank account details and the fix as re-linking the bank account and trying again. If the bank sent the same deposit twice, contact support with your transfer receipt.
