Dallas is one of the better cities to be a buyer of business internet. Fiber is lit in most office parks. Three real carriers will quote the same building. That means you have room to push on price. Most companies do not.
Here is what the market looks like in June 2026, and what to ask for.
Who actually serves Dallas
Four names show up on most quotes inside Loop 12 and out to Plano, Irving, and Richardson.
AT&T Business Fiber is the widest footprint. They have fiber in most commercial buildings in the metro. Their list pricing is high. Their negotiated pricing is not.
Spectrum Business runs cable across most of the city, and fiber in select buildings. Cable is cheaper. The upload speeds are slower. For a 20 person office that does video calls all day, that matters.
Frontier has fiber in parts of Dallas, mostly the older Verizon FiOS footprint and some recent builds in the suburbs. When Frontier is in the building, they tend to undercut AT&T by 10 to 20 percent on the same speed.
Logix Fiber Networks is the local one most people forget about. They lit a lot of downtown and Uptown buildings years ago. If your building has Logix, get a quote. They are often the lowest number on the page.
What you should be paying
These are real ranges we see on Dallas quotes this quarter, for symmetric fiber with a service level agreement.
500 Mbps runs about $450 to $750 a month. The low end is Spectrum or Frontier in a competitive building. The high end is AT&T with no other carrier in the building.
1 Gbps runs about $700 to $1,200. We saw a downtown law firm close at $795 with AT&T in May. Same building, AT&T had quoted $1,450 first.
10 Gbps is the wild one. Median is around $1,565 a month based on our last 19 samples nationally. Dallas tracks close to that, with a floor near $1,100 in fiber dense buildings and a ceiling north of $3,500 where only one carrier can deliver.
Cable internet from Spectrum runs $200 to $400 for 500 Mbps down, with much slower uploads. Fine for a retail shop. Not fine for a software team.
What to negotiate
Four things move on a Dallas renewal. Most people only ask about one.
The monthly rate. This is what everyone fights about. Get two competing quotes in writing, then send them to your current carrier 90 days before your contract ends. That window matters. Miss it and you roll into auto renewal at the same rate or higher.
The term length. AT&T and Spectrum both push 36 month deals. A 24 month deal is almost always available if you ask. A 12 month deal is sometimes available if you have a competing fiber quote in hand.
The install fee. On a renewal, this should be zero. On a new build, it can run $2,000 to $15,000 depending on the construction. Ask for it to be waived or amortized into the monthly rate.
The static IP block. A single static IP is usually free or $10. A block of 5 is usually $25 to $40. If you are paying $75 for IPs you are not using, that is a phone call.
One real Dallas story
A 40 person marketing agency in Deep Ellum had a 1 Gbps AT&T circuit at $1,295 a month. Three years, no renegotiation. We pulled a Spectrum fiber quote for the same building at $749 and a Logix quote at $689. AT&T came back at $795 with a 24 month term and waived the install on a second redundant circuit.
Savings: $6,000 a year on the primary. They added a redundant Spectrum line for $400 a month, which they did not have before. Net spend went up a little. Net resilience went up a lot.
That is the Dallas play. Use the competition. Most buildings have it. Most buyers do not use it.
