A method for providing insights based on merchant bidding includes: storing a plurality of transaction data entries, each including a merchant identifier and transaction data; receiving merchant bids, each being received from a different merchant and including a bid amount and corresponding merchant identifier; identifying a transaction metric based on the transaction data included in each transaction data entry; identifying a propensity to transact for each corresponding merchant identifier based on the transaction data included in each transaction data entry that includes the respective corresponding merchant identifier; determining a winning bid of the plurality of merchant bids based on a combination of the propensity to transact for the included corresponding merchant identifier and the included bid amount; and transmitting the account identifier included in the account profile to the merchant from which the winning bid was received.
