Brokerage Rankings: real estate brokerages AI recommends in Maine
In Maine, the GeoGenius Brokerage Rankings cover 1 metro (Portland, ME) where ChatGPT, Claude, Gemini and Grok have named 48 real estate agents. Grouped by the core brokerage brand those agents work for, Sotheby's International Realty has the most named agents in the state (9 across 1 metro), followed by Keller Williams (5) and Redfin (4). Offices, teams and franchise affiliates count toward their parent brand; the ranking measures presence in AI recommendations, not sales volume or headcount, and payment plays no part. Each metro below ranks every brokerage the engines named there.

How this ranking is built
GeoGenius asks ChatGPT, Claude, Gemini and Grok the questions a buyer or seller would ask about each metro and records every agent each engine names. Each named agent's brokerage is resolved to its core brand and the brands are ranked by named agents, then distinct responses, then distinct engines. The method mirrors our published 36-market study at https://geogenius.ai/ai-report.
