Madison is a two-horse fiber race with a cable incumbent on top. TDS Telecom is headquartered here, which matters. They have built more fiber inside the city limits than most national carriers manage in markets twice this size, and they price it like a local utility that knows its territory. Spectrum holds the cable footprint and most of the SMB volume by default. AT&T fiber is real but patchy, mostly hitting newer buildings on the west and south sides. The University of Wisconsin and the state government soak up the high-end enterprise spend, which means mid-market pricing here looks more like a Tier B metro than a Tier C one in some buildings.
Madison is mostly a Spectrum and TDS market. Spectrum Business has the dominant cable footprint. TDS Telecom has built fiber across most of the city and inner suburbs. AT&T Business Fiber covers parts of the metro. T-Mobile fixed wireless is widely available.
The pricing problem in Madison is the assumption that TDS is just the local phone company. They often deliver the cheapest fiber-to-the-building option in the metro for a single office.
Madison's commercial heart
Madison's commercial demand sits in three places. Downtown Madison holds the legal, financial, and government corridor centered on Capitol Square and the State Capitol Complex. Greater State Street, the pedestrian commercial spine running from the Capitol to the University of Wisconsin campus, anchors a deep cluster of restaurants, retail, and small-office tenancy. Capitol East, the redeveloping mixed-use district along East Washington Avenue, has filled in with adaptive-reuse office and creative-tech tenants over the past decade. The State of Wisconsin government and the University of Wisconsin-Madison are two of the largest commercial accounts in the metro and shape what enterprise telecom pricing looks like for the rest of the market.
Recent ISP buildout activity specific to Madison in 2023 to 2026 has been quieter than in many comparable metros, with the most active news coming from TDS Telecom's broader regional fiber expansion rather than a Madison-specific announcement. One pricing wrinkle: Properties in Madison's Central Business Improvement District fund supplemental downtown services through a separate BID assessment structure alongside normal city services, 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.
Madison 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.
Analyze My Bill FreeFor TDS Telecom Business Fiber at 1 Gbps, expect $130 to $200 a month for a single office. For Spectrum coax at 600 Mbps, the fair price is $150 to $230 a month.

Carriers worth a quote here
- TDS Telecom Business
TDS is the home-team fiber play in Madison. Strong coverage downtown, on the isthmus, and through the inner west and east sides. They will negotiate harder than a national carrier on a 36-month single-site deal, especially against a Spectrum quote.
- Spectrum Business
Dominant SMB cable footprint across the entire metro, including suburbs like Middleton, Fitchburg, Sun Prairie, and Verona. Default choice for sub-$500 monthly accounts. Process-driven, slow to discount, but will move on price if you have a written TDS or AT&T quote in hand.
- AT&T Business
Fiber pockets on the west side, near American Family Insurance's campus, and in newer commercial developments along the Beltline. Off-net everywhere else, which makes pricing inconsistent block to block. Worth a quote if your building is on-net, not worth the wait if it isn't.
- Lumen Business
Limited Madison metro fiber, mostly long-haul transit and selective enterprise buildings downtown. Currently hungry for business and will discount aggressively on multi-site deals. Not a realistic option for most single-office SMBs here.
- T-Mobile Business
Fixed wireless is broadly available across the metro and useful as a backup circuit or a primary for a small office that doesn't need an SLA. Pricing is flat and predictable, typically $50 to $90 a month.
- Everstream
Regional fiber operator with a Midwest footprint that touches selected Madison enterprise buildings. Worth pricing if you need a diverse second carrier and want to avoid a Spectrum or TDS resale that shares a local loop.

Madison, Wisconsin market notes
Common questions about business internet in Madison, Wisconsin
Is TDS Telecom actually cheaper than Spectrum in Madison?
Often yes for dedicated fiber, especially at 500Mbps and above with a 36-month term. For business broadband under $300 a month, Spectrum usually wins on headline price but loses on hidden fees, modem rentals, and contract terms. Get both quotes in writing and compare total monthly cost including equipment and surcharges, not just the MRC.
Can I get AT&T Business Fiber at my Madison office?
Maybe. AT&T fiber coverage in Madison is uneven. The west side near the Beltline, parts of Fitchburg, and some newer downtown buildings are on-net. Most older buildings on the isthmus and east side are not. Run an address check before you spend time on a quote, and don't accept an off-net price as competitive.
What should I pay for 1Gbps dedicated internet in Madison?
Between $1,195 and $1,600 a month if your building is on-net with TDS, AT&T, or Spectrum Enterprise. Push toward the lower end with a 36-month term and a competing quote. Off-net or single-tenant buildings can hit $1,800 to $2,000 because the carrier has to build or lease a local loop. If you're paying over $2,000, you're overpaying.
Is T-Mobile fixed wireless a real option for a Madison business?
It's a real option for a small office, a backup circuit, or a retail location that doesn't need an SLA. Speeds typically run 100 to 300Mbps down with variable latency. Don't use it as primary internet for VoIP-heavy operations or anything that needs guaranteed uptime. It's a $60 to $90 monthly tool, not a fiber replacement.
How do I avoid an auto-renewal on my Spectrum or TDS contract?
Both default to month-to-month after term, but you have to give written notice in the cancellation window, typically 30 days for Spectrum and 60 days for TDS. Put a calendar reminder 120 days before contract end. If you miss the window, you're stuck at evergreen pricing that's almost always above current market by 20 to 40 percent.
Do I need diverse carriers in Madison, and does it actually work?
Diverse carriers only protect you if the physical fiber paths are actually separate. In Madison, Spectrum and TDS use different plant in most of the city, so true diversity is achievable. Verify entry points at the building MPOE and confirm with both carriers in writing. Two circuits sharing the same conduit isn't redundancy, it's two bills.
