The private markets secondaries space has entered a new chapter. What was once a niche corner of alternative investments, used primarily by limited partners (LPs) seeking early exits from fund commitments, has grown into one of the most dynamic segments of global private capital. The market has tripled in size since 2019 and grown by approximately 50% between 2024 and 2025 alone, reaching an estimated $230 billion in annual transaction volume and now representing around 5% of all global private equity assets under management. 

This piece examines the forces behind that expansion, the structural shifts redefining the market, and the operational and regulatory challenges participants will need to navigate as the asset class continues to scale.

Market Growth and Shifting Deal Dynamics

Several converging factors have driven the secondaries market to its current size. A prolonged slowdown in IPO activity and traditional exits has created a liquidity bottleneck across private markets, leaving many LPs over-allocated to alternatives and constrained in their ability to make new commitments. The secondary market has become a primary mechanism for these investors to rebalance portfolios and free up capital.

Deal structuring has grown more sophisticated in step with market volumes. Ropes & Gray has observed a continued expansion in the use of purchase price deferrals and earnouts, and more recently, the introduction of deal-specific funding caps, limits on how much capital a buyer can be called to deploy before a specified date. These mechanisms allow sellers to achieve higher reference-date pricing while enabling buyers to manage capital deployment pacing and portfolio composition. In Q1 2026 alone, institutions initiated new secondary sales processes totaling north of $20 billion, some linked to denominator effect concerns as declines in public market portfolios pushed private allocations above target levels. Whether this proves a sustained driver of supply will depend on how institutional portfolios weather current market conditions.

The Three Transaction Types

Secondary transactions fall into three main categories: 

• LP-led transactions, the original form, involve an LP selling existing fund interests, sometimes across a broad portfolio of hundreds of positions, typically through competitive auction processes with tight timelines. 
• GP-led continuation funds, the fastest-growing segment, involve a sponsor transferring select assets into a new vehicle, giving existing LPs the option to cash out or roll forward. As of 2025, GP-led and LP-led volumes are roughly evenly split at around $115 billion each. GP-led buyout fund volume grew 39% year-over-year, while private credit secondaries saw nearly 300% year-over-year growth in GP-led activity. 
• The third category, structured solutions, provides capital to a GP collateralized by existing fund assets and can take a wide variety of bespoke forms.

What Are the Operational and ESG Challenges in the Market?

One of the defining challenges in secondaries is the speed and scale of due diligence required, particularly in LP-led transactions. Buyers may need to evaluate hundreds, or in private credit secondaries, over a thousand, underlying positions with limited information and within windows of 24 to 48 hours. As Jessica Huang, Managing Director and ESG lead for private equity and secondaries at Ares Management, noted in a recent webinar:

Against this backdrop, LP expectations around ESG integration have risen sharply. LPs are now holding secondaries to a standard closer to that applied to direct investments, with requests for Article 8-classified funds, look-through exclusion lists, and UN Global Compact compliance screening becoming more common. Main exclusion categories include fossil fuels, controversial weapons, tobacco, and gambling, though definitions and revenue thresholds vary significantly across mandates. SFDR 2.0, currently in draft form, may introduce additional mandatory exclusion categories that managers are monitoring closely. In LP-led deals where buyers are inheriting a broad portfolio of assets, highly granular opt-outs can mean missing certain large transactions, a trade-off that must be clearly communicated to LPs.

The Role of Technology and AI

Technology has become central to the scaling of secondaries operations. AI tools are now applied across controversy screening, ESG data analysis, and emissions estimation, where direct disclosures are unavailable. A particular challenge in the asset class is coverage: many underlying companies are small or mid-market private businesses not captured in conventional databases.

Market participants consistently emphasize that AI outputs serve as inputs to human judgment, not as replacements for it. At Ares, screening results are reviewed by ESG specialists before being passed to deal teams for final decisions.

What the Future Holds

Transaction volumes are forecast to continue rising as both the seller and buyer universes expand. Private credit, infrastructure, and structured secondaries all represent areas of growing specialization and regional expansion, particularly in Asia, where secondary activity has been limited but is expected to grow as investment programs mature, broadening the market further. Capital supply dynamics bear watching: while dry powder remains substantial, deal volume growth has outpaced fundraising since 2023, which could create pricing or capital constraints. The entry of retail investors through evergreen vehicles adds a meaningful new source of capital but brings different liquidity expectations and regulatory considerations.

On the operational side, the sophistication of deal terms, the complexity of ESG compliance, and the volume of data processed per transaction are all increasing. Firms that can integrate technology into their diligence and monitoring workflows, while preserving the human judgment layer, will be best positioned to manage market growth. Secondaries are no longer a supplementary liquidity tool; they have become a structural feature of how private markets operate.

Executive Summary

The physical infrastructure powering the AI boom (the data centers that house it, and the hardware that runs it) has become one of the most ESG-exposed sectors in the global economy. As demand for computing accelerates, so does the scrutiny on the companies enabling it.

This scorecard examines three major players across the AI infrastructure stack: Equinix and Digital Realty, two of the world's largest data center operators, and Supermicro, a leading manufacturer of high-performance AI server hardware. Despite their different roles, all three are navigating the same storm: a convergence of governance failures, environmental friction, and national security risk that is reshaping how investors, regulators, and communities assess the sector.

Our analysis reveals three defining pressure points: governance failures spanning accounting manipulation, board instability, and fraud; environmental and social friction from community opposition, resource strain, and safety violations; and national security exposure through data breaches, export control violations, and supply chain risk.

Together, these risks represent a fundamental shift for the sector. ESG in AI infrastructure is no longer about carbon reporting - it is about fiduciary integrity, operational transparency, and the social license to keep building.

Supermicro: Fraud, Malware & Supply Chain Violations

With a controversy exposure score (CES) of 80/100, Supermicro’s ESG profile is dominated by extreme governance risks centered on systemic accounting failures and geopolitical compliance breaches. The company is currently battling a U.S. Justice Department probe, Nasdaq delisting threats, and a series of securities fraud lawsuits following a 2024 accounting scandal that forced the search for a new CFO and echoed a prior $17.5 million SEC fine from 2020. 

Beyond financial integrity, the firm faces severe national security scrutiny over the alleged smuggling of restricted Nvidia AI chips to China, alongside 2025 investigations into "spy chips," unremovable motherboard malware, and multiple patent infringement claims from competitors like AMD and Lenovo. Socially, the company’s risk is compounded by a 2025 whistleblower retaliation suit and labor rights violations involving Filipino workers at its semiconductor supply chain partners, as well as multiple OSHA safety penalties for workplace hazards.

Equinix: Accounting Manipulation & the AI Infrastructure Backlash

Similarly, Equinix’s CES of 79/100 is defined by a volatile combination of intensifying community opposition, environmental resource strain, and severe governance scrutiny. Socially and environmentally, the company faces a "Global AI Arms Race" backlash, where massive 340-acre proposals on local farmland in Minooka and "green belt" developments in South Mimms have sparked significant resident opposition over air pollution and traffic, while regulators in Dublin have begun blocking gas-powered facilities that violate national climate targets. These operational hurdles are compounded by a lack of transparency regarding massive water consumption and a series of high-profile safety and security failures, including data center fires in São Paulo and Madrid and a recurring "cybersecurity blind spot" in building systems. On the governance front, Equinix is navigating a severe trust deficit following a $41.5 million settlement over allegations of "major accounting manipulations" and the systematic over-selling of power capacity.

Digital Realty: Board Instability, Gas Leaks & Cybersecurity Breaches

Although it has a lower CES of 48/100, Digital Realty’s ESG profile is defined by governance instability and intensifying environmental friction in key urban hubs. The abrupt 2022 termination of its CEO and the 2023 resignation of its Chairman, who alleged bias against female directors, highlight deep-seated board-level conflicts, further exacerbated by 2026 investigations into director bias and a $3.4 million loss of tax breaks in Hillsboro. 

Environmentally, the company faces formal legal notices in Marseille over fluorinated gas leaks and "imminent dangers to health," as well as noise complaints in Chicago and a 2024 fire in Singapore. Socially, the firm is navigating a Biometric Information Privacy Act (BIPA) lawsuit over scanning workers' fingerprints without consent, a major 2025 "Salt Typhoon" hacking breach, and mounting federal scrutiny over the industry's role in driving up local electricity and water costs.

Conclusion 

The ESG challenges facing AI infrastructure operators are no longer peripheral concerns; they have become central to the sector's long-term viability. As the cases of Equinix, Supermicro, and Digital Realty illustrate, the consequences of their unchecked growth range from community backlash and environmental violations to governance failures and national security breaches. The AI infrastructure industry stands at an inflection point: continued expansion without proportional investment in transparency, accountability, and sustainability risks eroding stakeholder trust, inviting heavier regulation, and ultimately undermining the very infrastructure it seeks to build.

Northvolt was Europe's flagship battery champion, backed by Volkswagen, Goldman Sachs, BMW, and BlackRock, and capitalized with over $13 billion in debt and equity. Yet between 2022 and 2025, it became the largest industrial bankruptcy in modern Swedish history,  shocking the industry and investors alike. We took a look back at SESAM’s controversy data to see if there were any early warning signals.

The Warning Signs

In September 2022, the first public reports of production delays emerged at Northvolt's Skellefteå gigafactory. By the end of 2023, less than 1% of the planned 16 GWh capacity for 2024 had been delivered. Then came the fatal workplace accidents linked to electrical experiments, and in June 2024, BMW canceled a €2 billion contract. By September, 1,600 employees had been laid off, the cathode expansion was abandoned, and the CFO was replaced. 

The Fallout

The consequences were swift. A Chapter 11 filing in the U.S. in November 2024. The resignation of founder and CEO Peter Carlsson. Over 5,000 jobs lost. Major write-downs across the cap table, from sovereign-backed pension funds to global automakers. In March 2025, Northvolt filed for bankruptcy in Sweden, the largest industrial failure in the country's modern history. The reputational damage extended well beyond the company itself, reaching investors, suppliers, and the broader European battery ambition.
