How brokerages are measured
Brokerage rankings sit on a different scale than agents and teams, but the logic rhymes. Total closed sales volume is the headline figure and the primary sort. Beyond it, we weigh reach — the office and agent network that determines how much inventory a firm can touch — and brand equity in the luxury tier, where a name like Sotheby's or Christie's carries measurable pull. Note that franchise brands aggregate many independent offices, so their totals are not directly comparable to a company-owned brokerage. For the underlying framework, see the agent ranking methodology.
