No.

First of all, the spread is not the same as a commission. A commission is a fee charged to facilitate a transaction.

Second, the bid is where the market is willing to buy. The ask/offer is where the market is willing to sell. The difference between the two is the spread. Every market has a spread, though it’s not always immediately visible.
