A "Bid Price", is the price at which someone is willing to buy something. In most markets, it is lower than the "ask" or "offer" price, which is the price at which people are willing to sell. The difference between the two prices is called a bid-ask spread.Bids are made continuously by market makers for a security and may also be made in cases where a seller requests a price where they can sell. Sometimes, a buyer will present a bid even if there isn't an active seller, in which case it's considered an unsolicited bid.
