Gmail and kw.com lead the Montana addresses
No domain turns up on more Montana rows than gmail.com, 278, with kw.com close behind at 255. The next four are company domains: bhhsmt.com (199), exprealty.com (151), remax.net (119) and eralambros.com (65). Every RE/MAX agent in the file writes from remax.net.
93% of the Montana rows include a phone number, and 18% use a free mailbox.
Our October 2026 walks first found 309 of the Montana rows: they are new to our file, which does not make them newly licensed. No Montana row was last confirmed at its published source before Sep 16, 2026; the most recent confirmations are from Oct 8, 2026.
Berkshire Hathaway nearly even with Keller Williams
Keller Williams and Berkshire Hathaway HomeServices have almost the same number of Montana agents on file, 302 and 292. Keller Williams holds about the share it has in our US file, 19% of the branded agents here and 19% there. The Berkshire Hathaway share in Montana is more than double its share of our US file, 19% to 8%.
ERA and eXp Realty each carry more than three times their weight in our US file: ERA 9% of Montana's branded agents against 2%, eXp 11% against 3%. By company name, ERA Lambros Real Estate has 62 rows in our Montana file and ERA Landmark Real Estate has 41.
Coldwell Banker ranks second among the brands in our US file, yet its Montana share is about half of its share there, 8% against 15%. Sotheby's International Realty stands at nearly double the weight it carries in our US file (4% here, 2% there), and 40 of its 61 agents here work in Bigfork, Whitefish and Big Sky.
Bozeman ahead of Billings and Missoula
Montana grew by an estimated 113,200 people, or 11%, between 2015 and 2025, reaching 1.14 million, and the growth was concentrated in the western and south-central parts of the state. Gallatin County, which includes Bozeman, added about 27,700 residents (27%); Flathead County, which includes Kalispell, added about 19,500 (20%), by the Legislative Fiscal Division's June 2026 reading of Census estimates (Montana Legislature). In the Census Bureau's 2025 estimates, released in January 2026, every state except Montana and West Virginia saw its growth slow or its decline speed up.
Five city files hold more than a hundred Montana email addresses each: Bozeman (314), Billings (272), Missoula (248), Kalispell (153) and Helena (152).
Bozeman has both of the biggest company-and-town groups: Berkshire Hathaway HomeServices (70) and Keller Williams (68).
Nearly all of Keller Williams' Montana agents on file work in five cities: Bozeman, Missoula, Helena, Billings and Kalispell.
ERA Lambros Real Estate in Missoula, with 50 rows, is the only company-and-town group in the table below that is neither Keller Williams nor Berkshire Hathaway.
Century 21 has the most agents in Billings (41) and Helena (36), and only 8 in Bozeman, the largest city file. RE/MAX has no more than 13 agents in any one city and 2 in Billings, the second-largest city file. eXp Realty's biggest city count, 35 in Billings, is under a quarter of its Montana agents, who name at least 20 places in all.
