👉 In the context of business and finance, an "underbidder" refers to a bidder who bids below the market price for goods or services. This is akin to a buyer who buys at a lower price than they would in the open market. Underbidding can be seen as a strategy where the underbidder aims to take advantage of the seller's uncertainty by taking on more risk, which could lead to an increase in their bid if the actual sale price is higher than what they were bidding
