Internet service in the United States comes through several different types of networks. Cable still connects millions of homes, fiber is reaching more cities and smaller communities every year, and 5G home internet has created another option for households that previously depended on a cable or telephone company.
Satellite internet has changed as well. Starlink has made low-Earth-orbit satellite broadband a practical option in places where running fiber or cable is difficult. At the same time, large providers including AT&T, Verizon and Brightspeed continue putting billions of dollars into new fiber networks.
The list of major internet service providers in USA has also changed because of recent acquisitions. Charter completed its acquisition of Cox Communications in August 2026, bringing former Cox markets under the Spectrum business. Verizon completed its acquisition of Frontier in January 2026, giving the company a much larger fiber footprint.
This article covers 10 important providers based on customer numbers, network size, technology, service area and current expansion. It is not a strict subscriber ranking because the companies do not report their businesses in exactly the same way. Cable companies usually publish broadband customers, fiber builders often report locations passed, while Starlink reports its subscriber base globally.

| Parent Company | Charter Communications |
| Headquarters | Stamford, Connecticut |
| Internet Customers | 34 million+ |
| Main Technology | Cable and fiber broadband |
Spectrum became even larger in 2026 after Charter Communications completed its acquisition of Cox Communications.
Before the transaction, Charter already had 29.4 million internet customers at the end of June 2026. Cox brought another large broadband footprint, including markets such as Phoenix, San Diego, Las Vegas, Oklahoma City, New Orleans and parts of Virginia and New England.
The combined company now reports more than 34 million internet customers. Spectrum products are available across 45 states, while its overall network can reach more than 70 million homes and businesses.
Spectrum mainly delivers residential internet through its hybrid fiber-coaxial network, although the company also builds full fiber in many new rural areas. It has been upgrading the wider network to support symmetrical and multi-gigabit speeds and expects that network evolution to continue through 2027.
The provider has also started combining home broadband with mobile connectivity. Its Invincible WiFi product, introduced in 2026, includes Wi-Fi 7 together with 5G cellular and battery backup to help keep a home connected during certain broadband or power interruptions.

| Parent Company | Comcast |
| Headquarters | Philadelphia, Pennsylvania |
| Residential Broadband Customers | 28.5 million |
| Main Technology | Cable and fiber-powered broadband |
Xfinity has been one of the largest home-internet brands in the United States for years.
Comcast had approximately 28.5 million domestic residential broadband customers at the end of June 2026. That figure does not include the company’s complete business-services operation, which also provides internet and networking to companies.
Most Xfinity customers connect through Comcast’s hybrid fiber-coaxial infrastructure rather than a fiber cable running all the way into the home. Fiber still carries a large part of the traffic deeper inside the network before the final connection reaches customers.
Comcast has spent several years upgrading that network using newer DOCSIS technology. The goal is to offer faster uploads and multi-gigabit service without rebuilding every existing neighborhood as a completely new fiber-to-the-home network.
Internet is also becoming closely linked with Xfinity Mobile. Comcast passed 10 million domestic wireless lines in the second quarter of 2026, giving the company another way to bundle home and mobile connectivity.
Xfinity therefore remains one of the largest internet service providers in USA, particularly in metropolitan and suburban markets.

| Headquarters | New York, New York |
| Broadband Connections | 17.1 million |
| Main Internet Brands | Fios and Verizon 5G Home |
| Main Technology | Fiber and fixed wireless |
Verizon’s home-internet business now operates on a much larger scale than it did only a few years ago.
The company has two main ways of connecting households. Verizon Fios uses fiber directly to homes and businesses, while Verizon 5G Home Internet delivers broadband through the company’s wireless network.
A major change came on January 20, 2026, when Verizon completed its acquisition of Frontier Communications. The transaction expanded its fiber broadband footprint to 31 states and Washington, D.C.
The Frontier deal also increased the number of locations Verizon’s fiber networks can reach to more than 30 million homes and businesses. Former Frontier networks remain at different stages of integration, so customers may still encounter Frontier branding in some places.
By June 2026, Verizon had approximately 17.1 million fixed wireless and fiber broadband connections. It added 348,000 broadband connections during the second quarter alone, including 193,000 fixed wireless and 155,000 fiber additions.
That combination of Fios, acquired Frontier fiber and 5G Home gives Verizon several ways to compete for a household’s internet service.
Unique Offerings

| Headquarters | Dallas, Texas |
| Internet Connections | 15.5 million |
| Fiber Locations Reached | 38.6 million |
| Main Technology | Fiber and fixed wireless |
AT&T has spent several years moving its home-internet business away from older copper networks and toward fiber.
The result is now a large fiber operation.
At the end of June 2026, AT&T reported 15.48 million consumer and business internet connections across its advanced internet products. About 12.87 million were fiber connections and another 2.61 million used fixed wireless.
AT&T Fiber alone accounted for more than 12.1 million connections.
The physical network is considerably larger than the current customer base. By June, AT&T fiber had reached 38.6 million consumer and business locations. The company expects to pass more than 40 million locations by the end of 2026 and more than 60 million by the end of 2030.
AT&T also offers Internet Air, which uses its wireless network instead of a fixed fiber connection. Internet Air had nearly two million consumer connections by the end of the second quarter of 2026.
Fiber remains the more important long-term part of the company’s home broadband strategy, especially as customers use more connected devices and upload larger amounts of data.

| Headquarters | Bellevue, Washington |
| 2025 Broadband Customers | 9.45 million |
| 5G Broadband Customers | 8.45 million |
| Main Technology | 5G fixed wireless and fiber |
T-Mobile entered the home-internet market differently from most traditional broadband companies.
Instead of running a cable or fiber line into every house, T-Mobile Home Internet mainly uses excess capacity on the company’s 5G mobile network. A gateway inside the customer’s home connects to nearby T-Mobile towers and then provides Wi-Fi to household devices.
The business has grown quickly.
T-Mobile ended 2025 with approximately 9.45 million total broadband customers, including 8.45 million 5G broadband customers. It added about two million total broadband customers during that year.
Fiber has also started becoming part of T-Mobile’s plans. Acquisitions and investments involving Metronet and Lumos brought fiber customers into the business, and the company now markets fiber service under its wider broadband strategy.
T-Mobile expects the combination to become much larger. Its current target is 18 million to 19 million total broadband customers by 2030, consisting of about 15 million 5G broadband customers and three to four million fiber customers.
Fixed wireless will not perform the same at every address because signal strength, available network capacity and local conditions affect service. Even so, T-Mobile has shown that home broadband does not always need a physical wire running into the property.

| Company | Optimum Communications |
| Broadband Customers | About 4.0 million |
| Service Area | 21 states |
| Maximum Fiber Speed | Up to 8 Gbps |
Optimum is an important regional internet provider rather than a nationwide service.
The business was previously known at the corporate level as Altice USA, but the company changed its name to Optimum Communications in 2025. Its strongest markets include New York, New Jersey and Connecticut, although its wider footprint now covers 21 states.
Optimum had approximately 4.0 million broadband subscribers at the end of June 2026. The company lost 40,000 broadband customers during the second quarter as competition from fiber and fixed wireless remained strong.
At the same time, more customers are choosing its faster plans. Optimum reported that 53% of its residential broadband customers were taking 1 Gig or faster service by the end of the second quarter, up from 38% one year earlier.
The network is a mixture of cable and fiber. In areas with full fiber-to-the-home service, Optimum offers symmetrical speeds reaching 8 Gbps. Those fastest tiers are not available everywhere, and many customers still connect through the company’s cable infrastructure.
Unique Offerings
- Optimum Internet
- Fiber speeds up to 8 Gig
- Symmetrical fiber plans
- Cable broadband in wider service areas
- Optimum Mobile bundles
- No annual contract on many residential plans

Starlink

| Operator | SpaceX |
| Network Type | Low-Earth-orbit satellite |
| Global Subscribers, June 2026 | 12 million |
| Main Business | Satellite broadband |
Starlink has changed what satellite internet can do.
Older satellite services generally depended on satellites much farther above Earth. That distance created high latency, making activities such as online gaming and video calls more difficult.
Starlink uses a huge constellation of satellites in low Earth orbit instead.
SpaceX reported 12 million Starlink subscribers globally by the end of June 2026, twice the six million reported one year earlier. The company does not break out a current U.S.-only subscriber total in the same way large cable companies do.
An earlier Starlink network update said more than two million active U.S. customers were using the service by July 2025, showing how quickly satellite broadband had already grown inside the country.
Starlink is particularly useful where cable or fibre does not reach. A household needs the Starlink terminal and a reasonably clear view of the sky rather than a wired connection from a local provider.
Current U.S. residential plans advertise service reaching 400+ Mbps on the highest tier, although actual performance changes with location, network demand and other conditions.
Starlink therefore competes with traditional internet service providers in USA in a very different way. Its biggest advantage is not that it can outbuild fiber in a city, but that it can reach locations where building a physical network may be expensive or impractical.
Unique Offerings
- Low-Earth-orbit satellite internet
- Residential broadband
- Starlink Roam
- Connectivity for rural and remote locations
- Portable internet options

| Founded | 1995 |
| Service Footprint | 22 states |
| Locations Passed | 3 million+ |
| Main Technology | Cable and fiber-powered broadband |
Mediacom concentrates on smaller cities and towns rather than building its business mainly around the country’s largest metropolitan areas.
The company operates across 22 states, with a particularly strong presence in the Midwest and Southeast. It describes itself as the fifth-largest cable operator in the United States.
Its broadband network passes more than three million households and businesses.
Mediacom has also been increasing internet speeds without replacing the entire cable network with fiber-to-the-home.
In June 2026, the company made 2 Gig internet available across its entire national footprint, covering more than 3.1 million households passed by its fiber-powered network.
It has gone further in selected areas. Mediacom launched 5 Gig residential internet in May 2026, initially making it available to more than 500,000 homes in several states. The company said it expected that footprint to exceed one million homes by the end of the year.
This regional focus gives Mediacom an important role in markets where the largest national broadband brands may have a smaller presence.
Unique Offerings
- Mediacom Internet
- 2 Gig service across its footprint
- 5 Gig service in selected markets
- Wi-Fi 7 options

| Owner | Uniti Group |
| Service Area | 18 states |
| Fiber Locations Passed | 2 million+ |
| Main Technology | Fiber and legacy DSL |
Kinetic has a long history in fixed-line communications through Windstream, but the current business is increasingly about fiber.
Windstream and Uniti completed their merger in August 2025. Kinetic now operates as the residential and small-business broadband brand inside the combined Uniti Group.
Its network covers 18 states, with many customers in smaller towns, rural areas and suburban communities.
Kinetic passed an important milestone in June 2026 when its fiber network exceeded two million residential premises passed.
The construction has continued since then. During the second quarter of 2026 alone, Kinetic added another 141,000 fiber locations across its 18-state footprint.
The company sells several fiber tiers, including 1 Gig and 2 Gig plans in its wider fiber footprint. Certain markets have also received symmetrical service reaching as high as 8 Gig.
Not every Kinetic customer has fiber yet. Some parts of its older network still rely on DSL and other legacy infrastructure, which is why fiber construction remains central to the company’s plans.

| Operations Started | 2022 |
| Headquarters | Charlotte, North Carolina |
| Service Area | 20 states |
| Fiber-Enabled Locations | 3 million+ |
Brightspeed did not exist as a consumer internet provider until 2022.
The company began operations after Apollo-managed funds purchased telephone and broadband assets from Lumen Technologies. Those networks cover communities across 20 states, many of them in rural and suburban parts of the Midwest and Southeast.
Brightspeed inherited a large amount of older copper infrastructure, but most of its recent investment has gone into fiber.
By April 2026, its fiber network had passed more than three million homes and businesses. It had built more than one million new fiber passings in each of the previous two years.
The company expects to reach four million fiber-enabled locations by the end of 2026 and ultimately plans to exceed five million across its territory.
Brightspeed also offers multi-gig internet. Current fiber options include 1 Gig, 2 Gig and 5 Gig service, while the company’s 2026 Wi-Fi 7 launch also covered an 8 Gig tier where available.
Its importance comes largely from where that network is being built. Many of Brightspeed’s markets have historically had fewer high-speed broadband choices than large U.S. cities.

- Brightspeed Fiber
- Multi-gig internet
- Wi-Fi 7 on gig-speed plans
- Rural and suburban broadband

Why the Internet Service Industry Is Important in the USA
Cable Still Connects Tens of Millions of Homes
Fiber receives much of the attention around new broadband construction, but cable remains a huge part of U.S. internet access.
Spectrum now reports more than 34 million internet customers following the Cox transaction, while Comcast had about 28.5 million residential broadband customers before counting its complete business broadband operation.
Both companies are improving their existing networks instead of immediately replacing every cable connection with fiber.
That allows them to offer gigabit and increasingly multi-gigabit service across very large existing footprints.
Fiber Is Expanding Quickly
The biggest fixed-broadband investment story is fiber.
AT&T had reached 38.6 million consumer and business locations with fiber by June 2026. Verizon’s acquisition of Frontier pushed its combined fiber availability beyond 30 million locations.
Smaller companies are building quickly as well.
Brightspeed has passed three million locations, while Kinetic has moved beyond two million residential fiber premises. Optimum continues converting more of its network to fiber, and many regional providers are doing the same.
The reason is fairly simple. A fiber cable can carry very large amounts of data and can deliver fast uploads as well as downloads. That becomes increasingly useful as households add more devices, upload video and files, work from home and use cloud-based applications.
5G Home Internet Has Created a New Competitor
A household no longer always needs cable or fiber to get fixed home internet.
T-Mobile and Verizon have turned their mobile networks into home-broadband networks as well. AT&T is taking a similar approach with Internet Air.
T-Mobile had already reached 8.45 million 5G broadband customers by the end of 2025, while Verizon had more than 5.7 million fixed wireless customers at the end of that year.
Fixed wireless is particularly attractive because a provider does not need to dig up a street or run a new cable into every home.
The trade-off is that performance depends more heavily on wireless capacity and conditions at the customer’s location. Fiber normally offers more predictable capacity and symmetrical upload speeds.
Satellite Internet Is No Longer Only a Last Resort
Satellite broadband used to be associated mainly with slow connections in places where nothing else was available.
Starlink has changed that perception.
Its low-Earth-orbit network now supports ordinary internet activities such as video streaming, remote work and video calls while reaching properties far away from conventional broadband networks. SpaceX reported 12 million Starlink subscribers worldwide by June 2026.
Satellite still has capacity and performance limitations, particularly compared with a high-quality fiber connection. Its value becomes much clearer, however, when the alternative is very slow DSL or no fixed broadband at all.
Rural Broadband Is Receiving More Investment
Many of the largest American cities already have several broadband choices. Smaller communities can look very different.
That is why companies such as Brightspeed, Kinetic, Mediacom and Spectrum have been putting more money into rural and smaller-market networks.
Brightspeed is working toward more than five million fiber-enabled locations across its territory. Kinetic continues adding hundreds of thousands of new fiber passings, while Mediacom has made multi-gig service available across a footprint concentrated heavily in smaller markets.
These builds matter because internet access now supports much more than entertainment. Remote work, education, healthcare, banking and government services all depend heavily on a reliable connection.
Acquisitions Are Changing Familiar Internet Brands
The broadband map changed considerably during 2025 and 2026.
Verizon completed its Frontier acquisition in January 2026. Charter bought Cox Communications in August. Windstream had already combined with Uniti in August 2025.
Customers may still see some older names while networks, billing systems and products are integrated, but the companies behind those services have changed.
That is why Cox and Frontier are not separate entries in this current list of internet service providers in USA.
Conclusion
The top internet service providers in USA now use several very different technologies to reach customers.
Spectrum and Xfinity still operate the country’s largest cable-based broadband businesses. Charter’s acquisition of Cox has made the Spectrum footprint even larger, while Comcast continues upgrading Xfinity for faster and more symmetrical service.
Verizon and AT&T combine large fiber networks with fixed wireless internet. Verizon’s purchase of Frontier significantly expanded its fiber business, while AT&T continues building millions of new fiber locations.
T-Mobile has proved that a mobile network can also support a large home-internet business. Optimum remains an important regional cable and fiber provider, with speeds reaching 8 Gig in selected fiber markets.
Starlink approaches the same problem from space and has become especially important for rural and remote properties.
Mediacom, Kinetic and Brightspeed fill another important part of the market. All three have substantial operations outside America’s biggest cities, and each is spending money on faster networks in communities where broadband competition has historically been more limited.
Choosing between these providers therefore starts with the address, not simply the company name. Spectrum may be available on one side of a city while Xfinity serves another. One home may have AT&T Fiber, while a nearby property can only get fixed wireless. In remote areas, Starlink may be the practical choice.
The best starting point is to identify which networks actually reach the property and then compare the connection type, available speed, upload performance, price, equipment charges and any limits attached to the plan.
Frequently Asked Questions
Which is the largest internet service provider in the USA?
Spectrum now reports more than 34 million internet customers following Charter Communications’ acquisition of Cox Communications in August 2026. Comcast’s Xfinity is another very large provider, with approximately 28.5 million domestic residential broadband customers at the end of June 2026.
What are the biggest internet providers in the USA?
Spectrum, Xfinity, Verizon, AT&T and T-Mobile operate some of the country’s largest consumer broadband businesses. Other major providers include Optimum, Starlink, Mediacom, Kinetic and Brightspeed, although their service areas and network technologies differ considerably.
Which internet providers offer fiber in the USA?
AT&T, Verizon, Optimum, Brightspeed and Kinetic all operate substantial fiber-to-the-home networks. Spectrum and Xfinity also use extensive fiber inside their networks and deploy full fiber in selected areas. T-Mobile has additionally entered fiber through investments and acquisitions.
Is Cox still an internet provider?
Charter Communications completed its acquisition of Cox Communications on August 20, 2026. Former Cox customers are being moved into the wider Spectrum business, and Spectrum products, pricing and branding began rolling out across Cox markets in September 2026.
Is Frontier Internet now Verizon?
Yes. Verizon completed its acquisition of Frontier Communications on January 20, 2026. Frontier became a wholly owned Verizon subsidiary, giving Verizon a much larger fiber footprint across the United States.
Which internet provider has the fastest speeds?
Several U.S. providers offer multi-gigabit plans, but availability depends on the address. Optimum offers fiber speeds up to 8 Gbps in selected markets, while Brightspeed and Kinetic also have very high-speed fiber tiers in parts of their networks. Advertised maximum speed alone does not determine actual customer performance.
Is 5G home internet the same as fiber?
No. Fiber sends data through physical fiber-optic cables running to the property. 5G home internet connects a household wirelessly to a nearby cellular network. Fiber generally offers more consistent capacity and faster upload speeds, while 5G can be easier and cheaper to deploy.
Is Starlink available in the USA?
Yes. Starlink provides residential satellite internet across the United States, subject to local capacity and availability. It is particularly useful for rural and remote properties where cable or fiber broadband may not reach.
Which internet providers serve rural areas?
Starlink, Mediacom, Brightspeed, Kinetic and Spectrum all have significant rural operations or expansion projects. AT&T and Verizon also serve many rural locations through fiber, fixed wireless or older fixed-line networks, depending on the area.
How should I choose an internet service provider?
Start by checking which providers actually serve your address. Then compare the connection technology, download and upload speeds, monthly price, equipment costs, contracts, data limits and how the price changes after any introductory period. Fiber is usually worth considering first when a strong fiber connection is available.
