Fiber’s Next Phase: Built for AI, Built for Scale

Fiber broadband expansion in the United States is entering a new phase—one defined less by simple coverage metrics and more by capacity, resilience, and long-term strategic value. Across the country, providers are investing in fiber infrastructure that is simultaneously being built up to support artificial intelligence and hyperscale workloads, out into smaller and mid-sized communities, and deep enough to deliver multi-gigabit and even ultra-high-speed services as a mainstream offering.

Recent announcements from Vero Fiber Networks, RightFiber, and GFiber illustrate how these trends are converging. While each project targets a different segment of the market, together they reflect a broader shift in how fiber is planned, funded, and deployed—and why it is increasingly viewed as foundational national infrastructure rather than a discretionary upgrade.

At the high end of the market, fiber construction is increasingly driven by the needs of artificial intelligence, cloud platforms, and data center ecosystems. In 2025, Vero Fiber Networks completed approximately 790 miles of underground, multi-conduit fiber routes spanning Nevada, Iowa, California, Texas, and Tennessee. These builds were explicitly designed to support high fiber counts, route diversity, and long-term scalability.

As opposed to incremental network upgrades, AI-oriented fiber routes are often greenfield projects that cross complex geographies and require significant upfront investment. The payoff is infrastructure capable of supporting hyperscale traffic volumes, low-latency interconnection, and future expansion without repeated construction. As AI workloads continue to grow and distribute geographically, demand for physically diverse, underground fiber routes is becoming a core requirement rather than a niche consideration.

This approach reflects a broader change in how network operators and large enterprise customers evaluate fiber assets. Instead of optimizing solely for near-term returns, providers are increasingly treating these routes as long-lived strategic infrastructure—designed to support evolving technologies over decades, not just current bandwidth needs.

Extending Fiber Outward & Pushing Speeds Higher

At the same time, fiber investment is not limited to hyperscale corridors or major metros. Projects like RightFiber’s new build in El Dorado, Arkansas show how private capital continues to drive last-mile expansion into mid-sized and smaller markets. The deployment will deliver fiber-based internet service to residents and businesses, supporting higher speeds, improved reliability, and future-proof capacity.

These types of builds underscore fiber’s expanding role in local economic development. While community engagement and branding often accompany market entry, the lasting impact lies in expanded access to symmetrical, high-capacity connectivity that supports education, healthcare, remote work, and small business growth. As fiber extends further into regional markets, it raises the baseline level of broadband performance and reliability across entire states.

Meanwhile, fiber operators are also pushing the upper bounds of what consumer and small business broadband can deliver. GFiber’s announcement that roughly 90% of its footprint can now support symmetrical 20 Gbps service highlights how ultra-high-capacity fiber is moving closer to mainstream availability. Enabled by next-generation PON technologies and upgraded network hardware, these speeds far exceed traditional gigabit benchmarks.

While only a subset of customers may require 20 Gbps service today, the significance lies in what the underlying infrastructure enables. As networks mature, service tiers once considered experimental are becoming standard options, reshaping expectations around speed, symmetry, and long-term headroom.

Viewed together, these developments point to a converging strategy across the fiber industry. Providers are no longer choosing between building backbone infrastructure, expanding last-mile coverage, or increasing access speeds. Increasingly, they are doing all three in parallel.

The latest wave of fiber investment reflects more than incremental network expansion. It signals a shift toward fiber as durable, strategic infrastructure—built to handle AI-driven traffic growth, reach deeper into underserved markets, and support service levels that continue to redefine “high speed.” As these networks come online, they are reshaping the digital foundation on which future applications, industries, and communities will depend.
