The American broadband landscape has undergone a big transformation in the span of just three years. Driven by aggressive fiber deployment, the rapid rise of fixed wireless access (FWA), and the maturation of low-Earth orbit (LEO) satellite, competition has gone from the exception to the rule. For ISPs, the implications are profound, and the window to establish long-term revenue footholds is narrowing.

Fiber Is Spreading

According to the FCC Broadband Data Collection (BDC) data, just 37% of U.S. residential locations had access to fiber broadband in mid-2022. By mid-2025, that figure had climbed to 56% - meaning more than half of all American households can now access fiber. That shift represents approximately 23 million new locations connected to fiber infrastructure over the past three years.

The pace of expansion has been remarkably consistent: six to seven percentage points of household coverage gained per year. AT&T alone leads the national buildout by a wide margin, followed by a growing tier of overbuilders - companies like Metronet, Brightspeed, Ripple Fiber, and Open Infra - that are increasingly competing in markets once considered the exclusive domain of the ILECs.

Fiber overbuilding, once considered economically unviable, is now a defining market dynamic. As of mid-2025, nearly 1 in 10 U.S. households had access to two or more fiber providers - up from just 2.9% three years earlier, according to FCC BDC data.

Competition Has Fundamentally Shifted

Perhaps the most striking finding from the FCC data is the speed at which multi-provider competition has spread. In 2022, the majority of U.S. households had only a single broadband option. By mid-2025, 71% of households had access to two or more terrestrial broadband providers at 100/20 Mbps speeds - and more than 38% had access to three or more.

Fixed wireless access has been a major catalyst. The three national MNOs - AT&T, T-Mobile, and Verizon - collectively expanded licensed FWA availability from 44% to 60% of residential locations between 2022 and 2025. Each carrier has taken a notably different approach: T-Mobile launched early but has maintained relatively flat coverage, allocating capacity selectively based on network conditions; Verizon has prioritized high speeds over breadth; and AT&T - a late entrant - has recently accelerated aggressively, rapidly expanding coverage footprint.

Meanwhile, the LEO satellite, driven by Starlink, now offers broadband-capable speeds to virtually the entire U.S. population, providing a connectivity backstop even in the most remote areas. When Starlink is included in the competitive count, 100% of U.S. locations have access to at least one provider.

The Digital Divide Is Closing - But Unevenly

The FCC BDC data shows meaningful progress on connectivity gaps. The share of U.S. residential locations without any terrestrial broadband access has fallen from 12% in 2022 to 6% by mid-2025. States like Massachusetts, New York, and Rhode Island have less than 1% of locations unserved, while Alaska, Vermont, and Montana still face significant geographic and topographic challenges.

Critically, this progress has occurred largely before BEAD deployments have begun at scale - suggesting further improvement ahead as federal funding reaches the most difficult-to-serve areas.

The MDU Opportunity: A Long-Term Revenue Imperative for ISPs

As the competitive environment intensifies and subscriber acquisition costs rise across greenfield markets, one segment stands out as both underserved and strategically valuable: multi-dwelling units (MDUs).

MDUs - apartment buildings, condominiums, and mixed-use developments - represent a structurally distinct market that many ISPs have historically underweighted. Under the FCC’s BDC reporting framework, a single MDU building is often recorded as a single broadband serviceable location, even if it houses dozens or hundreds of housing units. This means the true density of demand - and revenue potential - is systematically undercounted in the data.

For ISPs, this creates both a gap and an opportunity. A bulk service agreement with an MDU property can lock in consistent, predictable revenue for five to ten years at wholesale rates, insulating that subscriber base from the pricing pressure and churn dynamics of the open residential market. In an environment where gigabit service can retail for as low as $50 per month in competitive markets, MDU bulk contracts provide margin stability that per-unit residential pricing increasingly cannot.

The competitive landscape is beginning to reflect this shift. As overbuild activity spreads across major DMAs - particularly in Sun Belt markets like Atlanta, Houston, Dallas, Tampa, and Orlando, all of which ranked in the top ten for fiber investment in 2025 - ISPs that have not locked down MDU agreements in these markets risk ceding long-term, annuity-style revenue to faster-moving competitors.

The strategic case is clear: MDU bulk arrangements allow ISPs to amortize capital expenditure over a longer, more predictable revenue horizon. They reduce customer acquisition cost to near zero for the contracted units and provide a moat against overbuilders who would otherwise compete unit by unit.

ISPs that move proactively - prioritizing MDU outreach in markets with active fiber construction, structuring agreements that align pricing to long-term fiber economics, and building operational capabilities to serve property managers as a distinct customer segment - will be best positioned to capture a disproportionate share of this durable revenue stream before the competitive window closes.

Looking Ahead

The trajectory of U.S. broadband is clear: coverage is expanding, competition is deepening, and pricing pressure is structural. For ISPs of all sizes, the strategic imperative shifts from network construction to subscriber retention, revenue durability, and operational efficiency.

The MDU segment, largely invisible in aggregate FCC data but enormous in actual unit count and revenue potential, may be the most important battleground of the next phase of broadband competition. Those who recognize that early will have a significant advantage.
