Ares Secondaries Investment Boosts Sabey Data Center Properties

Executive Summary

Ares Secondaries has taken a position in Sabey Data Center Properties, while Andreessen Horowitz leads a $50 million funding round for Pearl Health's Medicare AI platform — two deals that together signal institutional capital's accelerating pivot toward AI-enabling infrastructure. The money follows the workload: as AI compute demand grows, so does the need for purpose-built, power-dense real estate. Data center developers and infrastructure investors stand to benefit most; traditional real estate and generalist infrastructure funds that have not repositioned toward digital assets face growing irrelevance. The InfraSale takeaway is direct — powered land with data center entitlements is attracting secondaries capital, not just development-stage equity, which signals a maturing and increasingly liquid asset class.

What Happened

Ares Secondaries, the secondary investment arm of Ares Management, has committed capital to Sabey Data Center Properties, a well-established data center operator with facilities across multiple U.S. markets. The transaction represents a secondaries-market entry, meaning Ares is acquiring an existing stake rather than funding new construction from scratch — a distinction that matters for how the broader market reads risk and liquidity in this asset class.

Separately, Andreessen Horowitz led a $50 million funding round for Pearl Health, a company building AI-driven platforms designed for Medicare risk management. While Pearl Health operates in healthcare rather than real estate, the round underscores how AI application layers — whether in clinical workflows or hyperscale compute — are drawing institutional conviction at the same moment.

The two deals, reported together, are not operationally linked. But their coincidence is signal, not noise: capital allocators ranging from secondaries specialists to top-tier venture firms are placing coordinated bets on AI infrastructure and the software that runs on top of it.

Why This Matters

Ares Secondaries' move into Sabey Data Center Properties tells the market something important: data center assets have reached the liquidity maturity required to support a secondaries market. Primary equity and development debt have dominated data center capital stacks for years. Secondary transactions require pricing consensus, willing sellers with embedded gains, and buyers confident in exit paths. All three conditions now appear to be met.

Sabey is not a speculative startup. It is an operator with operational campuses, existing tenants, and — critically — interconnection and power agreements already in place. Ares acquiring a secondary stake means those hard-won infrastructure positions are now being priced and traded like institutional real assets, comparable to core-plus logistics or stabilized office.

The Pearl Health round adds a second data point. AI platforms consuming clinical data at scale need compute, and that compute lives in data centers. Every dollar invested in AI software downstream creates upstream pressure on data center capacity, power procurement, and interconnection queues. Investors who read only the healthcare headline miss the infrastructure implication embedded in it.

Combined, these deals suggest that 2026 investment activity is not a single-sector story. It is a vertically integrated thesis: AI applications require AI infrastructure, and AI infrastructure requires powered, entitled, connected land.

Power & Interconnection Impact

Data center secondaries transactions are, at their core, transactions in disguise on power and interconnection rights. When Ares buys into Sabey, it is buying into contracted megawatts, utility relationships, and substation access — assets that can take years and hundreds of millions of dollars to replicate from scratch.

Industry context: The U.S. data center sector is operating against a backdrop of severe interconnection queue congestion in PJM, MISO, and CAISO. New entrants face multi-year queue timelines. Existing operators with cleared interconnection agreements hold a structural advantage that secondaries capital is now explicitly pricing.

Increased AI workload intensity — driven partly by platforms like Pearl Health that process large Medicare datasets — will compound power demand at colocation and hyperscale facilities. Operators that secured long-term power purchase agreements or utility service extensions in the 2021–2024 window are particularly well-positioned. New development without contracted power faces a more difficult path to financing.

Land, Zoning & Permitting Impact

Growing secondaries interest in stabilized data center assets creates a bifurcated land market. Entitled, permitted, and powered sites command significant premiums because they bypass the most time-consuming and uncertain phases of development. Raw land, even in markets with favorable power availability, faces a longer path to institutional-quality valuation.

Assumption: Municipalities that have already approved data center zoning and infrastructure corridors — and that can point to operating examples like Sabey campuses — are more likely to attract follow-on development capital than jurisdictions where permitting remains contested or undefined.

InfraSale Marketplace

Turn this intelligence into a deal

InfraSale connects landowners, developers, and tenants directly — skip the broker chain.

Developers and landowners should expect intensified scrutiny on environmental review, water use for cooling, and community impact disclosures as data center density increases in established markets. Several states have moved toward formal data center overlay districts or specific use permits, separating data centers from generic industrial zoning. This regulatory evolution is accelerating, not slowing.

Investment Takeaway

Secondaries liquidity is arriving. Ares' entry into Sabey signals that data center assets are maturing past development-stage risk. Expect more secondaries volume in 2026–2027 as early data center fund vintages seek exits.
Power rights are the underlying asset. Investors evaluating data center opportunities should underwrite the power position — contracted MW, utility relationship depth, and queue status — before underwriting the real estate.
AI software investment creates infrastructure demand. The Pearl Health round is a reminder that every funded AI application layer generates compute demand. Investors in AI software should also be tracking the data center capacity constraints that could become a bottleneck for portfolio companies.
Stabilized vs. development-stage valuation gap is widening. With interconnection queues extending and permitting timelines growing, the spread between entitled operational assets and greenfield sites will likely continue to expand.
Healthcare AI is a non-obvious data center demand driver. Medicare AI platforms processing claims, risk scores, and clinical records at scale represent a growing demand segment that is not always captured in traditional hyperscale or colocation demand forecasts.

InfraSale Market Angle

For investors active on InfraSale, the Ares-Sabey transaction is a benchmark event. It confirms that data center infrastructure — when it carries operational history, contracted power, and interconnection certainty — is now a secondaries-grade asset class. That raises the floor on how powered, entitled land is priced in primary transactions.

Developers holding sites with data center entitlements and power agreements should recognize that their assets are now competitive with operating real estate for the attention of institutional capital. Landowners in utility service territories with available substation capacity are sitting on increasingly strategic positions, whether or not they have broken ground.

Site selectors and capital allocators should be monitoring which markets have remaining substation headroom, utility incentive structures, and zoning frameworks that allow fast-track permitting. Those intersections — power, entitlement, and institutional demand — are where the next round of data center development and secondaries capital will concentrate.

Take Action

The Ares-Sabey transaction is a signal worth acting on. Institutional secondaries capital entering stabilized data center assets compresses return windows for primary investors and raises the value of sites already in the entitlement pipeline. If you hold powered land or a data center project seeking institutional visibility, now is a strong moment to get in front of active capital.

FAQ

What are the latest trends in data center investments?

Secondary-market transactions — where institutional investors acquire existing stakes in operational data centers — are emerging as a significant trend in 2026. Ares Secondaries' backing of Sabey Data Center Properties illustrates that data center assets are maturing into a liquid, tradeable asset class alongside logistics real estate and infrastructure funds. AI-driven compute demand is the primary catalyst pulling capital into the sector.

How does AI impact data center infrastructure?

AI workloads are significantly more power-intensive and compute-dense than traditional enterprise IT, requiring specialized facilities with high power density per rack, robust cooling systems, and reliable interconnection. Every AI application layer — from Medicare risk platforms like Pearl Health to large language model inference — generates sustained demand for colocation and hyperscale capacity. This upstream pressure is accelerating both new data center development and investment in existing operational assets.

What should investors consider when funding data centers?

Power position is the first underwriting factor: contracted megawatts, utility service agreements, and interconnection queue status determine whether a project can actually deliver capacity on schedule. Permitting and zoning certainty — including whether a jurisdiction has a defined data center use category — is the second critical variable. Beyond those, investors should evaluate cooling infrastructure, fiber connectivity, and operator track record, particularly for secondaries transactions where the asset is already operational.

How does the Sabey investment differ from a typical venture round?

Ares Secondaries is acquiring an existing ownership stake in an operating company, not providing growth capital for new construction. This secondaries structure means Ares is pricing a known, revenue-generating asset rather than underwriting development risk. It reflects confidence in the stability and cash flow profile of established data center operators and signals that the asset class has sufficient performance history to support secondary market pricing.
