All bids placed on a marketplace hosted by B-Stock act as "proxy" bids.
You bid the highest amount you are willing to bid so that the system will manage the bidding for you. The Current Bid displayed on each auction is equivalent to the second highest bidder's bid, plus one bid increment.
If the high bidder has placed a higher bid, it will not display. This allows bidders to know that if they place a proxy bid, they could still win the auction for any amount below or at their maximum bid.
Example: If you find an auction you are interested in that is currently at $1,000 without any bids and choose to bid $5,000, you will be winning the auction at $1,000. If another bidder places a bid for $1,100, you will be winning the auction at $1,125, one increment higher. The system will continue to automatically outbid other bidders on your half, but will never exceed your proxy bid of $5,000.
