Sioux Falls, SD has a highly concentrated broadband market (HHI: 40,667) where Viasat dominates with 100% coverage reach — 0 percentage points ahead of the next-largest provider, HughesNet at 100%. In highly concentrated markets, consumers typically see fewer promotional offers and less pressure on the leading provider to invest in network upgrades. The remaining 6 providers in Sioux Falls, SD cover a fraction of addresses, limiting their competitive impact. Research from the FCC shows that markets with one dominant provider average higher monthly costs compared to markets with two or more meaningfully overlapping competitors. Fiber internet is available from 3 providers (CenturyLink, AT&T Internet, Rise Broadband), with 62% fiber coverage, near the national average of 57%. Fiber delivers symmetrical upload and download speeds — a key advantage for households with multiple remote workers, video conference participants, or content creators who upload large files. Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Fixed wireless internet — including 5G home internet services — is available from T-Mobile and AT&T Internet, reaching 54% of addresses (well above the national fixed wireless average of 32%). Fixed wireless offers a no-installation alternative that is increasingly competitive with cable for everyday internet use, with speeds typically ranging from 50-300 Mbps download. Unlike satellite, fixed wireless delivers lower latency (20-40 ms), making it viable for video conferencing and gaming. Satellite internet (Viasat, HughesNet, Starlink) provides universal coverage as a last-resort option for addresses outside wired broadband service areas. Low-Earth-orbit (LEO) satellite from Starlink has improved latency to 20-60 ms, a significant improvement over geostationary services (600+ ms), making it a practical alternative for rural households without viable fixed-line options.

Fiber-optic availability at 50% is slightly below the national figure of 57%. The gap is modest, and ongoing FTTH expansion from national and regional carriers may close it within the next 1-2 years. Residents should check availability at their specific address, as fiber buildout often progresses neighborhood by neighborhood. Cable broadband reaches 83% of addresses — 11 points above the national cable average of 72%. Strong cable coverage ensures most households have access to speeds of 100 Mbps or higher, making cable a reliable fallback even where fiber has not yet arrived. Fixed wireless internet — including 5G home internet from T-Mobile and Verizon — covers 49% of addresses, 17 points above the national fixed wireless average of 32%. Higher-than-average wireless availability gives residents an additional competitive alternative that can keep wired ISP pricing in check. Fiber availability in this area is near the national average. The nationwide fiber buildout accelerated in 2024-2025, with BEAD program funding expected to push fiber availability above 60% by 2028.

South Dakota received $208 million in federal BEAD funding. The South Dakota GOED Broadband is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.
