  • 1,200-Mile Midwest Fiber Corridor Rides Old Rock Island Rail Lines

    1,200-Mile Midwest Fiber Corridor Rides Old Rock Island Rail Lines

    Midwest Fiber Networks (MWFN) and Midwest Fiberpath, LLC, together with Fiberpath partner Hawkeye Land Co., announced on August 27, 2026 an agreement to develop and commercialize approximately 1,200 miles of fiber corridors connecting Chicago, Omaha, Minneapolis and Kansas City. The announcement was issued from Glendale, Wisconsin and Cedar Rapids, Iowa.

    Under the agreement, MWFN becomes the key provider supporting commercialization and delivery of connectivity services across Hawkeye’s right-of-way corridor, with planned offerings spanning conduit, dark fiber and scalable lit services for carriers, hyperscalers, data centers, enterprises, utilities, and public- and private-sector organizations. Construction is anticipated to begin in Spring 2027; the parties say the project is in advanced engineering and materials procurement, with shipments scheduled before the end of 2026.

    Executive Summary

    The headline number is 1,200 miles of long-haul fiber route across the middle of the country. The more interesting number may be 106 — the count of Midwest counties in four states where Hawkeye Land Co. says it holds the exclusive, perpetual right to grant easements along former Rock Island Railroad corridors. That includes rail corridors running from Council Bluffs to Joliet and from Minneapolis to Kansas City. In long-haul fiber, the hardest thing to buy is not glass or conduit; it is a continuous, legally clean path across hundreds of separate landowners and jurisdictions. This agreement is essentially an attempt to convert a 40-year-old land-rights portfolio into a telecom platform.

    Why it matters: the AI buildout is pushing compute into secondary and tertiary markets — places chosen for power availability and land, not for network density. Those sites are only as useful as the routes that connect them, and in the Midwest a large share of legacy long-haul capacity funnels through Chicago. A route system with north–south and east–west legs that meet somewhere in the middle of Iowa rather than in Cook County changes the shape of what buyers can procure, and gives network planners a genuinely distinct path to price against.

    What is not yet established: the release discloses no capital cost, no financing structure, no anchor customers, no conduit or fiber counts, and no in-service date. It describes an agreement and an intent, backed by a stated procurement position. Those are meaningful signals — materials orders are harder to fake than a press release — but they are not the same as a funded, contracted build. Buyers should treat this as a credible route under development, not as available inventory.

    Route Diversity Is the Quiet Half of the AI Buildout

    Most coverage of AI infrastructure focuses on the compute: the campuses, the megawatts, the cooling. The connectivity layer gets less attention because it is less photogenic, but it constrains the same outcomes. A training cluster needs to ingest and checkpoint enormous datasets; an inference site needs low, predictable latency to the users and applications it serves. Both need to reach the interconnection points where carriers and cloud providers exchange traffic. Put a facility in a secondary market with cheap land and available power, and you have solved the expensive problem while creating a new one — the site is stranded unless multiple physically separate fiber paths reach it.

    “Route diversity” is the industry term for that separation. Two circuits sold as redundant are only redundant if they ride different physical paths; if both traverse the same bridge, the same conduit bank, or the same metro chokepoint, one backhoe or one building fire takes out both. In the Midwest, a great deal of legacy long-haul was engineered to converge on Chicago, historically the region’s dominant interconnection hub. That concentration is efficient until it isn’t. The announced corridor is pitched squarely at this problem, and the endpoint pairs Hawkeye names — Council Bluffs to Joliet, Minneapolis to Kansas City — describe an east–west leg and a north–south leg that cross well outside the Chicago metro.

    It is worth being precise about the claim, though. Chicago is explicitly one of the four markets the corridor connects, and the Council Bluffs–Joliet leg terminates in the Chicago area. The value proposition is not “avoid Chicago”; it is “reach Chicago on a path other people are not using, and reach Minneapolis or Kansas City without going through Chicago at all.” That is a narrower but more defensible pitch, and it is the one that matters to a network planner filling out a diversity matrix.

    The Asset Is the Right-of-Way, Not the Glass

    Fiber cable is a commodity. Splicing crews are a commodity. Continuous, permitted, long-term access to a linear path across four states is not. Hawkeye Land Co. has been in the business of selling crossing and longitudinal easements along former Rock Island corridors since 1985, which means the entitlement work that usually dominates a greenfield long-haul schedule — negotiating with hundreds of landowners, counties and agencies, one parcel at a time — is substantially pre-solved. That is the economic core of this deal, and Hawkeye’s CEO Rick Stickle framed it in exactly those terms, calling the partnership “the highest and best” use of the company’s property rights.

    The structure also explains the division of labor. Hawkeye holds the land rights but is not a telecom operator. Fiberpath is positioned as the corridor platform developer — a managed right-of-way system built for blank conduit and dense fiber deployments. MWFN brings the operating side: regional carrier relationships, service delivery, and the customer-facing commercial motion. Each party contributes the thing it would otherwise have to spend years and considerable capital acquiring. That is a sensible structure, and it is a common one in digital infrastructure, where land-rights holders increasingly partner rather than build.

    The risk in this shape is coordination. Three parties, three balance sheets, and revenue that arrives over decades in the form of long-dated capacity contracts. The release does not describe how economics are shared, whether MWFN’s role is exclusive, or what happens if one party wants to sell. None of that is unusual to withhold, but all of it affects how much confidence a large customer can place in a 20-year commitment on this route.

    Three Products, Three Different Businesses

    The announced service set — conduit, dark fiber, and lit services — reads as one offering but is really three businesses with different capital profiles and different buyers. Empty conduit is the rawest form: a buried plastic pipe a customer can blow its own cable through, typically sold to hyperscalers and large carriers who want to control their own fiber and upgrade it on their own schedule. Dark fiber is unlit strand: the customer supplies the optical electronics and gets full control of capacity, latency and encryption, which is why it appeals to operators building at scale. Lit services are finished bandwidth — the provider runs the equipment and sells a circuit at a stated speed.

    The economics run in the opposite direction from the sophistication. Conduit and dark fiber sales, often structured as long-term indefeasible-right-of-use agreements with substantial payment up front, are how corridor projects fund construction; they convert future revenue into present cash at the moment it is most needed. Lit services carry higher margins over time but require ongoing equipment investment, network operations, and a sales motion into a fragmented enterprise market. A route system that can sell all three has more ways to monetize each mile — but the first and largest deals almost always come from the conduit and dark-fiber end, which is exactly where hyperscaler demand currently sits.

    What Is Substantiated, and What Is Framing

    Two things in this release carry real weight. First, the Hawkeye rights are specific and checkable: an exclusive, perpetual easement-granting position across named corridors, held and commercially exercised for more than 40 years. Second, the procurement statement — advanced engineering and materials shipments scheduled before the end of 2026, ahead of a Spring 2027 construction start — implies committed spending. Companies do not typically order long-lead fiber and conduit materials for routes they are not serious about.

    Other elements are framing rather than fact. This release does not mention AI at all; the AI positioning comes from a companion Fiberpath announcement describing the same 1,200 miles as a “center-noded, multi-direction AI backbone.” That is a legitimate market read — AI demand is genuinely reshaping long-haul procurement — but readers should note it is the same asset described twice for two audiences, not two separate developments. Similarly, phrases like “key provider supporting the commercialization” describe a commercial role without defining its scope or exclusivity.

    An even-handed summary: this is a well-structured deal built on an unusually strong underlying asset, announced at the agreement stage with normal commercial confidentiality. It is not thin marketing — there is a real land-rights position and a stated procurement commitment behind it. It is also not yet a proven route. The distance between “agreement to advance” and “lit and sellable” is measured in years, and the milestones that would close that gap have not been published.

    Background

    The Chicago, Rock Island and Pacific Railroad ceased operations in 1980, and its corridors were broken up and sold. Hawkeye Land Co. was formed in 1985 around a durable piece of that estate: the exclusive, perpetual right to grant easements along the former Rock Island corridors across 106 Midwest counties in four states. For four decades that position has generated revenue from utilities and municipalities buying crossing and longitudinal easements. Railroad rights-of-way have long been prime telecom real estate for the same reason they were good railroad routes — they are straight, continuous, gently graded, and already assembled.

    The current interest in Midwest long-haul reflects where compute is going. Power availability, land cost and cooler climates have pushed data center development into Iowa, Nebraska, Wisconsin and the Dakotas, away from the coastal and Northern Virginia clusters. Those sites need long-haul routes that did not exist when the region’s fiber map was drawn around Chicago in the late 1990s and early 2000s. Several developers are now trying to monetize legacy linear rights-of-way to serve that demand; this agreement is one of them.

  • Nvidia’s 16 Zayo Routes Show New AI Fiber Gets Built Around an Anchor Tenant

    Nvidia’s 16 Zayo Routes Show New AI Fiber Gets Built Around an Anchor Tenant

    TL;DR · 30-second read

    The Short Version

    Nvidia, the company whose chips run most of today’s artificial intelligence, is the main customer for 16 new fiber-optic cable routes that Zayo is building across the United States.

    These cables are bundles of glass strands buried underground that carry data between cities. Zayo is laying them where there is enough electricity for the giant computer warehouses that AI needs.

    A rival network company says new long-distance cable usually loses money. Zayo’s answer was to sign a very large customer before digging. Neither company has said what it costs.

    Zayo Group has confirmed that Nvidia is the anchor tenant behind the “monster deal” it first described in April, when chief product and strategy officer Bill Long said the company was building 8,000 more route miles of fiber. Zayo executives told Fierce Network on August 7 that, in partnership with Nvidia, Zayo is building 16 new long-haul fiber routes in high-growth AI corridors across the U.S.: six entirely new (greenfield) routes and ten overbuilds that add fiber along existing Zayo paths. Nvidia is also leasing fiber on eight other Zayo long-haul routes that already had enough capacity.

    The program runs for several years, with the first routes expected as early as 2027 and the full set by 2030. Zayo declined to disclose the cost of the build or how much Nvidia is investing, saying only that it is “good business with an attractive return profile.”

    Executive Summary

    The world’s dominant AI chip supplier has become the named anchor customer for one of the largest new long-haul fiber builds in the United States. Long-haul fiber is the cable that links cities and regions, as opposed to the metro fiber inside a single city. Nvidia’s involvement spans 24 Zayo routes in total: six new, ten upgraded and eight leased as they stand.

    The announcement matters because it arrived the same week Lumen Technologies’ CFO, Chris Stansbury, said the economics of building new long-haul routes “stink” and that Lumen had walked away from several such deals. Lumen’s one exception, a Seattle-to-Minneapolis route called NorthLine, works financially because a partner is sharing it. Zayo’s Nvidia deal follows the same pattern. New intercity fiber for AI is getting built where a large, committed customer underwrites the route before construction begins.

    Zayo also says the routes were chosen by mapping where electrical power is available for future data centers, and that the conduit is sized well beyond Nvidia’s own needs. That makes the build relevant to every data center developer and cloud operator siting capacity along these corridors.

    Why an Anchor Tenant Changes the Math

    Building a new long-haul fiber route is expensive long before it earns anything. Zayo’s executives described what the work involves: dealing with hundreds of municipalities, regulators and permitting bodies, and coordinating multiple construction contractors. The money goes out during construction, while lease revenue arrives gradually over years. If a route is built on speculation and demand arrives slowly, the builder pays to finance an asset that is sitting idle.

    Lumen’s comments show this risk plainly. Stansbury said Lumen has “stepped away from a number of deals” because shareholder returns on greenfield routes are “awful.” Yet Lumen is building NorthLine because a partner, which it has not named, makes “the economics for that actually very good.” Zayo’s position rests on the same mechanism. With Nvidia committed as anchor tenant across 16 new or upgraded routes plus eight existing ones, Zayo starts construction with a large share of demand already contracted. It describes the result as an attractive return. The two companies reach opposite verdicts on greenfield fiber in general, but they agree on the condition that makes it work: a committed buyer before the trench is dug.

    This is a pattern in two data points, not a law of the market. Zayo also argues that its experience building new routes over the past seven or eight years gives it a cost and execution edge competitors lack. Because neither the cost nor Nvidia’s commitment has been disclosed, outsiders cannot check the return claim. What they can see is that the one greenfield build each company is pursuing has a large partner behind it.

    Fiber Is Now Following the Power Map

    Long said Zayo began seeing sharply higher long-haul demand about two years ago, in the form of orders for far higher fiber counts than before. The company responded by analysing where electrical power was available across the U.S. and concluding that those corridors were where bulk fiber would be needed. Bulk fiber means large quantities of strands sold to a few big users rather than small circuits sold to many.

    This reverses the traditional logic of long-haul networks, which were drawn between population centers and internet exchange points. AI data centers need hundreds of megawatts of electricity, and that power is scarcer than land or fiber, so it now decides where these facilities go. Fiber is being planned to meet them there. For developers, a site with both secured power and a new high-count fiber route nearby becomes more valuable. For utilities and regional economic planners, a new route can signal that data center projects are expected to follow.

    Built Bigger Than One Customer

    Zayo CEO Steve Smith said popular routes will carry at least 1,728 fibers, and that the conduit going into the ground can support up to 20,000. Conduit is the protective pipe that cables are pulled through, and it can be filled with more fiber over time. Long said Nvidia wanted a build package that would serve “the rest of the ecosystem” as well as its own use.

    For Zayo, oversizing the conduit turns an anchor-backed build into a multi-tenant asset. Pulling additional cable through existing conduit is typically far cheaper than new trenching, so every later customer on the route improves returns on the original construction. Cloud providers, newer GPU-cloud operators and other carriers would all be potential buyers. The main risk is timing. With completion stretching to 2030, the build depends on AI data center demand in these corridors holding up for years.

    Mostly Upgrades, Not Blank-Slate Builds

    Of the 24 routes Nvidia is using, only six are true greenfield builds. Ten are overbuilds on existing Zayo fiber, and eight needed no new construction at all. Overbuilds can typically draw on existing paths and permissions, which reduces permitting risk and cost compared with new routes. That mix suggests the deal leans heavily on Zayo’s existing footprint. It also suggests the greenfield portion, which Lumen called hardest to finance, is the smaller share of the program.

    Background

    Zayo Group is a U.S. fiber infrastructure provider that sells bandwidth and bulk fiber to carriers, cloud providers and large enterprises. Its executives say it has been the only company building new long-haul routes at scale in the U.S. over the past seven or eight years. It has also grown through acquisitions, including a $4.25 billion fiber deal with Crown Castle. Zayo reports that AI has driven a sharp rise in long-haul demand, with customers ordering much higher fiber counts than in the past.

    Nvidia is the leading supplier of the processors used to train and run AI models, and its customers are building large data centers wherever power is available. Lumen Technologies, formerly CenturyLink, operates one of the largest U.S. fiber networks and competes with Zayo for AI-driven long-haul demand.

  • Verizon’s $1B+ Google Deal Shows Why Old Telecom Fiber Is Now AI Infrastructure

    Verizon’s $1B+ Google Deal Shows Why Old Telecom Fiber Is Now AI Infrastructure

    TL;DR · 30-second read

    The Short Version

    Verizon, best known for phone service, will supply Google with unused fiber-optic cable in a deal worth more than $1 billion. Fiber-optic cables are glass lines that carry internet traffic as pulses of light.

    Google needs the cable to link its data centers, the warehouse-sized buildings full of computers that run artificial intelligence. Those buildings must constantly swap huge amounts of data.

    The surprise is that much of this cable was laid for an older internet. Artificial intelligence has turned it into something worth a fortune, and Verizon says more deals worth billions are coming this year.

    Verizon Communications has signed a dark fiber agreement with Alphabet’s Google worth more than $1 billion, Quartz reported. CEO Dan Schulman disclosed the deal on Verizon’s second-quarter earnings call on Friday, July 24, 2026. Under the agreement, Verizon will provide dark fiber to connect Google’s data centers.

    Schulman said Verizon expects to announce additional AI infrastructure agreements by year-end that would generate multiple billions of dollars in revenue over the next several years. Verizon shares rose more than 3% in Friday’s opening trade, and Alphabet’s Class A shares gained about 1%.

    Executive Summary

    Verizon is selling Google access to dark fiber, meaning optical cable with no transmission equipment attached, which Google will light with its own gear to link its data centers. The disclosed value is more than $1 billion. Schulman called the announcement “consequential” and a preview of where Verizon’s revenue trajectory is headed.

    The deal matters beyond one contract. Schulman argued that Verizon’s long-haul and metro fiber, originally built for a different technological era, now fits precisely what is needed to connect AI data centers, compute clusters and geographic regions. If he is right, fiber routes already in the ground are becoming a strategic input to AI buildouts, alongside power and chips, and carriers holding those routes gain a new class of long-term customer.

    What remains unproven is scale. One deal is disclosed; the “multiple billions” are a forecast. The year-end pipeline is what will show whether this is a durable revenue line or a single large transaction.

    Why Fiber Built for Another Era Now Sells as AI Infrastructure

    Dark fiber is the rawest form of network capacity a carrier can sell: strands of glass with no lasers or routers attached. The buyer installs its own optical equipment at each end, decides how much data to push through, and upgrades on its own schedule. For a company like Google, that means the capacity between its sites is set by its own engineering choices rather than by a carrier’s service tiers, which is why large cloud operators favor it for their most important links.

    AI changes how much those links matter. Large AI workloads increasingly span multiple buildings and regions, so data centers must move enormous volumes of data between one another. Schulman’s claim is that Verizon’s network, though built for an earlier era, fits “precisely” what is needed to link AI data centers, compute clusters and geographic regions. The operational point is that the glass itself is rarely the scarce part. The scarce parts are the installed routes, rights-of-way and permits, which take years to assemble and which an incumbent carrier already holds. A more-than-$1 billion commitment from Google is a concrete price signal that those existing routes now carry AI-era value.

    That reprices assets across the industry. Other owners of long-haul fiber now have a public comparable for what a hyperscaler will commit. Data center developers have another reason to weigh proximity to established fiber corridors alongside power availability. And for hyperscalers, leasing proven routes is one way to connect new campuses without waiting on new construction.

    A Billion-Dollar Headline Without the Fine Print

    Markets took the news seriously. Verizon stock rose more than 3% at Friday’s open, a notable move for a large, mature telecom carrier, and Alphabet’s Class A shares gained about 1%. Investors appear to be reading the deal as evidence that Verizon can earn growth revenue from assets it already owns, rather than only from its consumer wireless business.

    The economics are harder to judge than the headline. “More than $1 billion” does not say over how many years that value is earned, how many route miles or strands are involved, or whether payment is largely upfront or spread across the term. Dark fiber deals can carry attractive margins when the cable is already in the ground, but Verizon has not said how much new construction, such as short connecting routes to Google’s sites, the agreement requires. Those details determine whether this is a high-margin monetization of sunk investment or a capital project with a customer attached.

    The Year-End Test for Verizon’s AI Pitch

    Schulman framed Google as the beginning, not the peak. He said additional agreements expected by year-end would generate multiple billions of dollars in revenue over the next several years, describing them as stable, extended-term arrangements with some of the most technically rigorous customers in infrastructure. That is a specific, checkable commitment, and it will define how the Google deal is judged.

    There are structural limits to watch. Dark fiber inventory is finite: a strand provided to one customer is not available to another, so sustained growth eventually depends on how much spare capacity Verizon holds on the routes AI customers want, or on building more. Hyperscalers also have alternatives, including other fiber owners and their own construction, which will shape pricing. None of this undercuts the Google deal; it frames the question of whether a network built for an earlier era can supply AI demand at the scale Schulman describes.

    Background

    Verizon Communications is one of the largest US telecom carriers, known mainly for wireless and broadband service. It also owns long-haul fiber connecting cities and regions and metro fiber within urban areas. Schulman, now CEO, argues that this network, originally built for a different technological era, suits the connectivity needs of AI data centers.

    Google, owned by Alphabet, is one of the hyperscalers building large-scale AI infrastructure. As AI computing spreads across multiple campuses and regions, the network links between data centers have become a strategic requirement. Large cloud operators commonly buy dark fiber on long-term agreements and light it with their own equipment, keeping control of capacity and upgrades.

  • Zayo Closes $4.25B Crown Castle Fiber Deal, Redrawing the US Long-Haul Map

    Zayo Closes $4.25B Crown Castle Fiber Deal, Redrawing the US Long-Haul Map

    Zayo Group has completed its $4.25 billion acquisition of Crown Castle’s fiber business, according to a May 2, 2026 report from Fierce Network. The close finalizes a transaction first announced in March 2025, when Crown Castle agreed to exit fiber entirely by splitting the segment between Zayo, which took the fiber solutions business, and EQT, which took the small-cell operations, in a combined deal valued at roughly $8.5 billion.

    The completion makes Zayo — already one of North America’s largest independent bandwidth-infrastructure providers — a substantially bigger force in both long-haul and metro fiber, while returning Crown Castle to its roots as a pure-play wireless tower company.

    Executive Summary

    The announcement itself is short: the deal has closed. But the closing matters more than most, because it formally redraws the ownership map of US fiber at a moment when fiber has shifted from a commodity business to a strategic one. Long-haul fiber — the high-capacity routes that carry traffic between cities — and metro fiber — the dense local networks that connect buildings, data centers, and cell sites within a city — are both being repriced by the AI build-out, as hyperscalers and data center developers scramble to connect new campuses.

    For Zayo, the acquisition is a bet that scale wins in that environment: more routes, more conduit, more on-net buildings, and more ability to sell end-to-end connectivity to the customers spending most aggressively. For Crown Castle, it is the final step in unwinding a decade-long fiber strategy that the market never rewarded, refocusing the company on towers. Two companies looked at the same asset class and reached opposite conclusions — which is precisely what makes this deal worth watching.

    Fiber Is Having Its Moment — and Zayo Is Consolidating Into It

    For most of the 2010s, long-haul fiber was treated as a mature, low-growth business: capacity was abundant, prices declined steadily, and the assets traded hands repeatedly among private-equity owners. The AI infrastructure cycle has changed that calculus. New data center campuses are being sited in secondary and rural markets where power is available but fiber often is not, and connecting those sites — to each other and to major interconnection hubs — requires exactly the kind of route diversity and dark fiber (unused fiber strands leased whole, rather than as managed bandwidth) that Zayo sells.

    Absorbing Crown Castle’s fiber business gives Zayo a much denser metro footprint to pair with its national backbone. In connectivity, density compounds: the more buildings and data centers a provider can reach on its own network, the more of each customer’s traffic it can carry without paying another carrier, and the better its margins and win rates. That logic, not nostalgia for telecom assets, is what a $4.25 billion price tag implies.

    Two Readings of the Same Asset

    The striking feature of this transaction is the strategic divergence it crystallizes. Crown Castle spent heavily to build its fiber segment in the mid-2010s — including the reported $7.1 billion purchase of Lightower in 2017 — on the thesis that fiber and small cells would complement its tower business. Investors, including prominent activist shareholders, ultimately disagreed, arguing the fiber business consumed capital while earning returns below the tower segment’s. The March 2025 agreement to sell the entire segment, and now its completion, is the definitive verdict of that internal debate: Crown Castle is a tower company again.

    Zayo’s owners are making the opposite wager — that fiber’s return profile has structurally improved with AI-era demand, and that assets underperforming inside a tower REIT can perform well inside a focused fiber operator with a different cost base and sales motion. Both positions are defensible. Crown Castle’s shareholders wanted capital discipline and simplicity; Zayo’s private owners can hold a capital-intensive asset through a demand cycle without quarterly scrutiny. The deal is less a judgment on fiber than on who is best structured to own it.

    Integration Is Where $4.25 Billion Deals Are Won or Lost

    Zayo was itself assembled through dozens of acquisitions, so network integration is a core competency — but this is among the largest single integrations it has attempted. Merging two national fiber operations means reconciling network inventories, OSS/BSS systems (the operational and billing software that tracks what fiber exists and who is paying for it), overlapping routes, and two sales organizations, all without disrupting enterprise and carrier customers who treat connectivity outages as existential. Historically, fiber roll-ups have stumbled less on the assets than on the systems and service quality during the merge.

    There is also a balance-sheet dimension. Fiber consolidation of this scale is typically debt-financed, and the sector’s private owners have been navigating a higher-rate environment than the one in which many of these assets were last underwritten. Strong AI-driven demand improves the revenue side of that equation, but execution risk during integration is the variable Zayo most controls.

    What Changes for the Market

    For enterprise and wholesale buyers, one fewer independent fiber provider means the competitive set in some metros narrows, which bears watching on pricing and on route diversity — customers who deliberately bought from both companies for redundancy may now find both circuits on one network. For data center developers, a larger Zayo is arguably good news: a single counterparty that can deliver metro entrances and long-haul routes together simplifies procurement for new campuses. And for the remaining independent fiber operators, the deal resets the benchmark for what scaled fiber platforms are worth, which tends to invite further consolidation rather than end it.

    Background

    Zayo was founded in 2007 and grew into one of North America’s largest independent fiber operators through a long series of acquisitions, going public in 2014 before being taken private in 2020 by a consortium led by DigitalBridge and EQT. Crown Castle, one of the largest US tower REITs, moved aggressively into fiber in the mid-2010s — including the reported $7.1 billion acquisition of Lightower in 2017 — betting that fiber and small cells would complement its tower franchise.

    That bet faced years of investor pushback over returns on the fiber capital, culminating in a strategic review and the March 2025 agreement to sell the entire fiber segment for roughly $8.5 billion, split between Zayo and EQT. The May 2026 closing of Zayo’s $4.25 billion portion completes Crown Castle’s retreat to towers and lands just as AI data center construction has made fiber routes one of the most sought-after asset classes in digital infrastructure.
