SK Telecom (NYSE: SKM) said on August 27, 2026 that it will split its wholly owned subsidiary SK Broadband in two, moving the data center and submarine cable businesses into a newly established company called SK Horizon while the surviving SK Broadband keeps fixed-line, media and enterprise operations. The book-value split ratio is roughly 0.84 to the surviving company and 0.16 to the new one.

Alongside the spin-off, SKT signed a definitive agreement for a combined KRW 3.08 trillion equity investment in SK Horizon from funds managed by KKR and from the IMM Investment–Stonebridge consortium. Once all phases of the investment close, KKR will hold 29% and the IMM consortium 20%, with SKT retaining management control at 51%. SK Horizon will carry eight operating data centers plus new AI data centers under construction in Ulsan and Guro, targeting 318 MW of total capacity. The company is due to be established in the first quarter of 2027, subject to an extraordinary general meeting of shareholders and government approvals.

Executive Summary

What SK Telecom announced is, on paper, a corporate reorganization. In practice it is a financing structure. Building AI data centers — facilities purpose-built to host the dense, power-hungry servers that train and run AI models — has become a capital problem that does not sit comfortably inside a telecom operator’s profit-and-loss statement. Carriers are valued on stable cash flows and dividends; multi-year, multi-billion-dollar construction programs with uncertain lease-up are valued on entirely different terms. SKT’s answer is to put the assets in a separate vehicle where infrastructure investors can fund them directly.

The capital comes from two very different pockets. KKR is one of the largest infrastructure investors globally, with over USD 100 billion in infrastructure assets under management and more than USD 70 billion deployed across digital and power assets; it is investing primarily from its Asia Pacific infrastructure strategy. The IMM Investment–Stonebridge consortium brings domestic Korean institutional capital — IMM manages over USD 7.5 billion, and Stonebridge has roughly KRW 3.6 trillion (USD 2.5 billion) in cumulative AUM. IMM’s infrastructure head framed the deal explicitly around “digital sovereignty,” pairing global capital with domestic ownership.

The structure matters as much as the money. SKT keeps 51% and management control, so SK Horizon remains consolidated and strategically directed, while 49% of the equity risk and funding burden is shared with outside investors. That is the template infrastructure investors have used for towers, fiber and power assets for a decade, now applied to AI compute capacity. If it works in Korea, other carriers sitting on data center estates will read it as a playbook.

Why the Carrier Balance Sheet Ran Out of Room

A telecom operator’s financial profile is built for predictability. Investors buy carriers for recurring subscription revenue and dividends, and they penalize capital intensity that does not convert quickly into cash. AI data center construction inverts that: heavy upfront spending on land, power connections, cooling and shell, with revenue arriving only after tenants sign and equipment lands. SKT’s own release makes the motive plain — the restructuring is meant to “enable focused investment” and let the unit “more effectively secure funding for key business areas, including through external investment.”

Separating the assets solves several problems at once. A standalone infrastructure company can raise equity from investors who underwrite long-duration assets on infrastructure return expectations rather than telecom multiples. It can also borrow against contracted capacity in ways a diversified carrier subsidiary cannot as cleanly. And it gives the parent a clean line between the businesses it wants valued for growth and the businesses it wants valued for stability — the surviving SK Broadband is explicitly pointed at fixed-line, media and enterprise.

The trade-off is dilution of economics. SKT is giving up 49% of the upside in what it calls Korea’s leading AI data center platform in exchange for capital and speed. Whether that is a good trade depends entirely on numbers the release does not provide: the valuation implied by KRW 3.08 trillion for a 49% stake, and how much of the buildout that money actually funds.

Three Companies, One Buildout — and a Gap Worth Noticing

SKT has now described a three-tier structure. SKT itself sets strategy and handles relationships with global big tech customers. SK Horizon operates and expands the existing estate — eight live data centers in Seocho, Ilsan (two sites), Bundang, Gasan, Centum, Yangju and Pangyo, plus new AI data centers under construction in Ulsan and Guro, working toward 318 MW of total capacity. SK Hyper, established in July 2026, handles business development for new gigawatt-scale projects, with 5 GW targeted for phased opening in 2029 and expansion toward 15 GW by 2035.

The gap between those figures is the single most important thing in the announcement, and it deserves plain language. Capacity in this industry is measured in megawatts of IT power, because power — not floor space — is the binding constraint. SK Horizon’s 318 MW target is roughly 0.3 GW. SK Hyper’s stated ambition is 15 GW, or about forty-seven times larger. The KRW 3.08 trillion announced here is an investment in SK Horizon, the operating platform, not in the 15 GW program.

That does not make the announcement small — a 318 MW portfolio with live, revenue-generating assets is a genuine platform, and having outside capital validate it is meaningful. But readers should not conflate the two. This deal funds the near-term expansion of an established estate. The gigawatt-scale ambition remains, on the evidence in this release, unfunded and undisclosed as to financing. Reading the announcement as “KKR is funding SKT’s 15 GW plan” would be wrong.

What Infrastructure Capital Is Actually Underwriting

KKR’s partner on the deal points to three things: an established operating platform, capacity under development, and a strong strategic partner. That is a fair summary of what makes a minority infrastructure position financeable. Operating assets generate cash from day one. Development pipeline provides growth without a greenfield land grab. And a 51% parent with customer relationships to global cloud and AI buyers reduces the risk that the platform is built and not filled.

The minority-with-control structure is deliberate on both sides. SKT avoids deconsolidation and keeps strategic direction. Investors get exposure without operating responsibility, and typically negotiate governance protections and exit mechanisms — neither of which the release describes. The presence of domestic Korean institutional capital alongside a global firm is also not incidental: critical national infrastructure carrying international submarine cable landings tends to attract regulatory attention, and a domestically anchored ownership structure is easier to approve.

For enterprise buyers, the practical read is mixed. A separately capitalized operator with committed equity behind it is generally a more reliable landlord than a subsidiary competing internally for capital. But private-equity-backed infrastructure also runs on return targets and eventual exits, which over a multi-year contract horizon can influence pricing discipline and reinvestment. Buyers signing long leases should ask about the investment’s phasing and about investor rights, not just the headline number.

Submarine Cables and the Sovereignty Argument

The less-discussed half of the carve-out is submarine cable infrastructure, which SK Horizon will expand in phases. Subsea cables are the fiber-optic lines on the ocean floor that carry essentially all intercontinental internet traffic. For AI specifically, they matter because training data, model weights and inference traffic move between regions, and because a data center campus is only as useful as the international capacity connecting it.

Bundling cables with data centers in a single vehicle is a coherent strategy: it lets one company sell capacity and connectivity together, and it is a structure that has proven attractive to infrastructure investors elsewhere because both asset classes share long lives and contracted revenue. IMM framed both as “core infrastructure assets shaping Korea’s digital sovereignty and industrial competitiveness” — a positioning argument that is currently more assertion than demonstrated outcome, but one that aligns with how several governments now treat compute and connectivity.

The competitive context is worth stating without overstating it. Korea has real advantages for AI infrastructure — dense fiber, an advanced digital economy, and domestic semiconductor and manufacturing demand. It also faces the same constraint every market faces: power availability and grid interconnection timelines. The release does not address power procurement at all, which is the question that determines whether any of these capacity targets are achievable on schedule.

Background

SK Telecom has operated in telecommunications since 1984 and is listed in the United States on the NYSE under the ticker SKM. In recent years it has repositioned around what it describes as a full-stack AI ecosystem spanning infrastructure, models and services. SK Broadband, its wholly owned subsidiary, has been the group’s fixed-line, media and data center arm, and the eight facilities now moving to SK Horizon make it one of Korea’s larger data center operators.

This announcement is the third step in a sequence rather than a standalone move. SKT previously said it would pursue an AI data center buildout of up to 15 GW with the aim of becoming an Asian AI infrastructure hub, and signed a memorandum of understanding with Supermicro and Schneider Electric covering total solutions for AI data center deployment. It established SK Hyper in July 2026 to develop new gigawatt-scale projects. With SK Horizon, the group now has a defined three-part structure: SKT setting strategy and handling global big tech relationships, SK Horizon operating and expanding the existing estate, and SK Hyper developing the next generation of sites.

Infrastructure investment firm I Squared Capital announced on May 26, 2026 the launch of a new United States data center platform focused on AI inference and edge colocation, backed by a $1 billion capital commitment. The announcement, distributed via Business Wire, positions the platform to serve the fast-growing market for running trained AI models close to users, rather than the massive centralized campuses where those models are built.

Executive Summary

I Squared Capital, a global infrastructure investor with a track record of building digital-infrastructure platforms from the ground up, is committing $1 billion to a US platform aimed at two intertwined markets: AI inference — the compute that answers queries after a model is trained — and edge colocation, meaning smaller data centers positioned in or near population centers where enterprises can rent space and power.

The bet matters because it stakes real capital on a specific view of where the AI buildout goes next. Most headline-grabbing investment to date has chased hyperscale training campuses measured in hundreds of megawatts, sited wherever cheap power exists. An inference-and-edge thesis argues the next wave of demand is distributed: many smaller facilities, closer to users, optimized for low latency and steady utilization rather than raw scale. If that view is right, data-center value will spread across many US metros instead of concentrating in a handful of power-rich regions.

Inference Is a Different Business Than Training

Training a large AI model is a batch job: it can run anywhere power is cheap, and users never interact with it directly. Inference is a service: every chatbot reply, search summary, and copilot suggestion is an inference call, and its economics are governed by latency (how fast a response travels to the user), utilization, and cost per query. That pushes inference capacity toward network-dense locations near people — the historic strength of colocation and edge facilities rather than remote gigawatt campuses.

By naming inference and edge together, I Squared is effectively arguing that the AI market is maturing from build-the-model to serve-the-model. Industry observers have long noted that if AI adoption follows the path of earlier computing waves, ongoing inference spending should eventually dwarf one-time training spending. A platform purpose-built for that phase is a bet on the durable, recurring part of the AI stack.

A Contrarian Read on Data-Center Geography

The prevailing US buildout has concentrated in a few power-abundant corridors — the kind of places where a utility can pledge hundreds of megawatts. Edge colocation inverts that logic: smaller footprints, more sites, and proximity to enterprises and consumers in secondary metros. The trade-off is that edge sites face urban land costs, tighter permitting, and constrained grid connections, but they can command premium pricing for low-latency capacity and are less exposed to the single-market risks of mega-campuses.

For enterprise buyers, a credible national inference-and-edge platform would offer an alternative to shipping every AI workload to a distant hyperscale region — relevant for latency-sensitive applications, data-residency requirements, and hybrid architectures that keep proprietary data close to home. For incumbent colocation providers, it signals a well-capitalized new competitor targeting exactly the niche where regional operators have historically differentiated.

What $1 Billion Buys — and What It Doesn’t

A $1 billion commitment is serious money and, at the same time, a measured entry. In today’s market, a single large hyperscale campus can absorb several billion dollars, so this commitment points toward a portfolio of smaller facilities rather than one flagship — consistent with the edge thesis. Infrastructure funds also routinely amplify equity commitments with project-level debt, so the platform’s ultimate buildout capacity could be a multiple of the headline figure, though the release itself does not say so.

I Squared has used the platform playbook before in digital infrastructure, assembling operating companies around a thesis and scaling them through acquisition and greenfield development. The open question is execution: inference-optimized facilities still need power, cooling for dense GPU racks, and — most importantly — tenants. The announcement describes a commitment and a strategy; converting that into leased, revenue-generating megawatts is a multi-year undertaking in a market where skilled operators, grid interconnection queues, and equipment lead times are all under strain.

Risks: The Edge-Inference Thesis Is Not Yet Settled

It is worth stating plainly that the distributed-inference future this platform anticipates is a forecast, not a fact. Today, a large share of inference still runs in the same hyperscale regions as training, because cloud providers concentrate their GPU fleets there and many applications tolerate tens of milliseconds of extra latency. If model efficiency improves faster than demand grows, or if hyperscalers simply extend their own regions closer to users, the addressable market for independent edge inference capacity could prove smaller than proponents expect.

None of that makes the bet unreasonable — infrastructure investing is precisely about positioning capital ahead of demand. But buyers and competitors evaluating this announcement should weigh that the release, as reported, substantiates a commitment and a strategy rather than contracted customers or operating assets.

Background

I Squared Capital is an independent infrastructure investment firm founded in 2012 and headquartered in Miami, managing capital across energy, utilities, transport, and digital infrastructure worldwide. In digital infrastructure specifically, the firm has favored a platform model — creating or acquiring an operating company around an investment thesis, then scaling it through greenfield development and bolt-on acquisitions, including prior edge data-center investments in Europe.

The announcement lands amid an unprecedented US data-center expansion driven by AI. Most capital to date has flowed to hyperscale training campuses in power-rich regions, but a growing school of thought holds that as AI applications reach mass adoption, the serving side — inference — will demand distributed, network-proximate capacity, reviving the strategic value of edge and metro colocation.

Infrastructure investor I Squared Capital has agreed to acquire data center assets from Cogent Communications for $225 million, according to a Reuters report dated May 25, 2026. The purchase anchors a new data center platform — reported at roughly $1 billion — that I Squared is positioning around artificial-intelligence inference, the day-to-day serving of AI models to users rather than the training of them.

Executive Summary

The transaction pairs a specific asset purchase with a bigger strategic wager. I Squared, a private-equity firm that specializes in infrastructure — roads, energy, and increasingly digital assets — is paying $225 million for facilities Cogent had been carrying on its books, and is using them as the foundation of a platform sized in press coverage at around $1 billion. The stated thesis is AI inference: the compute that answers queries, generates content, and runs AI features inside applications, which tends to sit closer to end users than the massive training campuses built by hyperscale cloud providers.

For Cogent, a company best known as a low-cost internet backbone and transit provider, the sale converts long-marketed real estate into cash. For the broader market, it is a data point that institutional capital now sees a distinct, investable asset class in smaller, distributed colocation sites — not just in the gigawatt-scale campuses that have dominated AI headlines. Whether inference demand materializes at these locations on the timeline investors hope is the open question the deal leaves unanswered.

Inference Is a Different Business Than Training

Most AI data center investment to date has chased training: enormous, power-hungry campuses where models are built, often in remote locations chosen for cheap land and available electricity. Inference — running the finished model every time a user asks a question — has a different profile. It is latency-sensitive, scales with user traffic rather than with model size, and in many architectures benefits from being distributed across metros closer to population centers. That is the logic behind putting inference capacity into smaller, geographically scattered facilities of the kind changing hands here.

The economics are also different. Training clusters are typically leased wholesale by a handful of very large tenants; inference capacity can, in principle, be sold in smaller increments to a broader customer base, which looks more like traditional retail colocation — renting secure, powered space to many customers. If that market develops, operators of distributed sites gain pricing power they have not had in years. If inference instead consolidates inside the hyperscalers’ own clouds, the thesis weakens. The release, as reported, does not settle which way demand is actually breaking.

A Payday for Cogent’s Conversion Thesis

Cogent acquired Sprint’s legacy wireline business from T-Mobile in 2023, a deal that brought with it a large portfolio of former telephone switching facilities across the United States. Management has spent the years since arguing that these buildings — hardened structures with existing power feeds and fiber connectivity — could be converted into sellable or leasable data centers. Skeptics noted that carrier hotels built for 1990s telecom gear are not automatically suited to modern high-density computing, and that monetization was slow to show up in reported results.

A $225 million sale to a sophisticated infrastructure buyer is the most concrete external validation of that thesis to date, though one transaction does not price the whole portfolio. It is worth being precise about what the deal does and does not prove: it shows a willing buyer at a real price for some assets, but the report does not disclose how many facilities are included, their capacity, or their condition — so extrapolating a value for Cogent’s remaining sites from this headline number would be premature.

Private Capital Moves Down-Market

I Squared’s entry continues a pattern of infrastructure funds treating digital assets — fiber, towers, and data centers — as core holdings alongside energy and transport. What is notable is the segment: rather than bidding on trophy hyperscale campuses, where competition from sovereign wealth funds and mega-funds has compressed returns, this platform targets the fragmented middle of the market. A reported $1 billion platform commitment suggests the firm intends to aggregate and upgrade additional sites, not simply hold what it bought.

The risks are equally clear. Retrofitting older facilities for AI-grade power density and cooling is capital-intensive, utility interconnection queues are long in many metros, and the platform will be competing for tenants against established colocation providers with existing sales channels and ecosystems. The strategy’s success likely depends less on the entry price than on execution: securing power upgrades, landing anchor customers, and timing capacity to a demand curve that remains genuinely uncertain.

Background

Cogent Communications built its business as an aggressive price competitor in internet transit, operating a global fiber backbone. Its 2023 acquisition of Sprint’s wireline business from T-Mobile brought hundreds of former telephone switching sites, and management has since pitched their conversion into data centers as a major source of untapped value — a claim the market has watched for proof in the form of actual sales or leases.

I Squared Capital is part of a wave of infrastructure private equity that has moved decisively into digital assets over the past decade, on the view that data centers, fiber, and towers offer the long-lived, contracted cash flows these funds seek. The AI boom has intensified that interest, first in massive training campuses and now, as this deal suggests, in the distributed facilities that may serve AI inference closer to end users.
