Market share is the percentage of total sales within a category that belongs to one company, calculated by comparing its revenue or unit sales against the entire market rather than looking at growth in isolation.

Because of this, share is often a better signal of competitive position than raw growth numbers alone, especially in a market that’s expanding overall.
