Sioux Falls is mostly a Midco and CenturyLink market. Midco Business has the dominant cable footprint across the metro. CenturyLink (Lumen) has fiber in parts of the city. SDN Communications serves commercial buildings with fiber. T-Mobile fixed wireless is widely available.
The pricing problem in Sioux Falls is the assumption that Midco is the only real choice. They often are the right answer for cable, but rarely the cheapest fiber option without a competing quote.
Sioux Falls' commercial heart
Sioux Falls' commercial demand sits in three places. Downtown Sioux Falls holds the legal, financial, and government corridor that anchors the city's daytime workforce and the bulk of its Class A office stock. The Riverline District, the redeveloping commercial zone the mayor has marketed as a near-downtown growth area, has filled in with creative-office, hospitality, and small business tenancy over the past several years. Foundation Park, the master-planned business and industrial park on the city's northwest edge, anchors a deep concentration of logistics, light-manufacturing, and back-office tenancy outside the urban core. Sanford Health and Avera Health, the two regional health systems that Sioux Falls Development Foundation lists among the city's largest employers, are two of the largest commercial accounts in the metro and drive heavy enterprise telecom demand.
On May 5, 2025, Midco announced that its multi-gig symmetrical speed upgrades were reaching Sioux Falls homes and businesses as part of its Fiber Forward investment, lifting the incumbent's headline-speed ceiling for commercial accounts in the metro. One pricing wrinkle: Downtown Sioux Falls property owners fund a self-imposed Business Improvement District assessment that pays for downtown marketing, maintenance, and economic development services, often passed through in commercial leases.
