Ask

The ask, or offer, is the lowest price at which a seller is currently willing to sell an asset. Together with the bid, the highest price a buyer will pay, it forms the two-sided quote that defines every market, and the gap between them is the bid-ask spread.

Why it matters

Anyone who buys at market pays the ask, so the spread is an immediate, unavoidable transaction cost. Spreads are tight where liquidity is deep, often a few hundredths of a percent in major markets, and wide where it is thin. Watching the ask side of an order book also reveals supply: a wall of sell orders at one price can cap a rally until it is absorbed.

Limit orders let buyers set their own price instead of lifting the ask, trading certainty of execution for a better level.

In the gold vs bitcoin debate

Retail buyers of the two assets face very different asks. A one-ounce gold coin typically sells at a premium of several percent above spot, a dealer ask that reflects fabrication, distribution, and inventory costs. Bitcoin on a liquid exchange can be bought within a fraction of a percent of the global price at almost any size. Over a long holding period the difference fades, but for frequent transactions the width of the ask is a real cost of choosing physical metal.
