Knoxville is mostly an AT&T and Comcast market with growing competition from KUB Fiber, the local utility fiber buildout. AT&T Business Fiber covers a large share of commercial blocks. Comcast Business has the dominant cable footprint. KUB has been rolling out fiber across the city since 2022. T-Mobile fixed wireless is widely available.
The pricing problem in Knoxville is the assumption that the utility fiber is just for residential. KUB Fiber business plans often beat AT&T and Comcast on price-to-speed where available.
Knoxville's commercial setup
Knoxville's commercial demand sits in three places. Gay Street is the historic commercial spine of downtown, lined with restored Class B office buildings and ground-floor retail. Market Square, just off Gay Street, is the small-format commercial and creative-office cluster built around the central plaza. The Old City, north of the railroad tracks, is the renovated warehouse district with mixed-use tenants and small business tenancy. Covenant Health, the largest healthcare system in East Tennessee, and Pilot Company, the truck-stop chain headquartered just outside Knoxville, are two of the largest commercial accounts in the metro and drive heavy enterprise telecom demand.
In 2025, the City of Knoxville said KUB Fiber's expansion had reached more Knox County neighborhoods and that more areas were scheduled for 2025 availability, expanding the reach of utility fiber to commercial blocks beyond the urban core. One pricing wrinkle: Downtown Knoxville's CBID is funded by a special assessment on property owners within the district, which is often passed through in commercial leases.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Knoxville dedicated internet, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes. Shown as a metro-tier band where city-level data is thin.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $1,060/mo | n = 6 |
| 500 Mbps | $955 – $1,660/mo | n = 6 |
| 1 Gbps | $1,195 – $2,000/mo | n = 7 |
| 10 Gbps | $1,560 – $6,250/mo | n = 6 |
If your bill sits above the high end of the band, you are likely overpaying.
