Keller Williams, eXp and two Coldwell Banker firms in South Dakota
Keller Williams agents make up 260 of the 699 South Dakota agents on file, every one of whom comes from a brand's roster: that is 37%, about double Keller Williams' 19% share among branded agents across the whole US file.
196 of them work from Sioux Falls. The next largest brokerage and city pairs in our file, Berkshire Hathaway HomeServices in Sioux Falls and Keller Williams in Rapid City, have 60 each, less than a third of that.
eXp Realty is far stronger in the South Dakota file than in our national one: 14% of the branded agents here, set against 3% across the US. Fewer than half of its agents here, 40, list Sioux Falls; the other 55 give 19 other places.
Coldwell Banker goes the other way, 9% here against 15% nationally, and all 61 of its agents on file work for two firms that carry its name: Coldwell Banker Black Hills Legacy Real Estate (36) and Coldwell Banker Empire Realty (25).
Sioux Falls, Rapid City and the Black Hills towns
Two cities hold 81% of the agents on file: Sioux Falls, with 379, and Rapid City, with 187.
Sioux Falls and Rapid City each have their own REALTOR board. The REALTOR Association of the Sioux Empire, founded in 1920, serves Sioux Falls, Brandon, Tea, Harrisburg, Dell Rapids, Canton and Madison. The Black Hills Association of REALTORS covers Rapid City and Piedmont, while the Mount Rushmore Area Association of REALTORS takes in Spearfish, Sturgis, Deadwood, Lead, Belle Fourche, Custer, Hill City and Hot Springs. Joining any local board also makes an agent a member of South Dakota REALTORS and of the National Association of REALTORS; in October 2026 the state association's site gave its member base as about 2,100.
Our file has 68 agents in those Mount Rushmore board towns, 40 of them in Spearfish.
The brand mix shifts with the map: 54 of the 90 RE/MAX agents on file work in Rapid City, and Century 21 has more agents in Aberdeen (15) than in Sioux Falls (3).
| Office | City | Agents on file |
