Large-scale, capital-intensive exposures are quickly redefining today’s risk landscape. Sectors with concentrated values and long-dated demand — including digital infrastructure — are expanding rapidly. This growth is creating risks that outpace traditional insurance capacity, contributing to limit shortfall and structural coverage gaps.

As a result, risk financing is increasingly influencing whether major projects can proceed. Insurance capacity now affects bankability, loan requirements and deal execution, making capital strategy a defining feature of project success.

These pressures are not cyclical. Capacity constraints for scaled and emerging risks persist across both hard and soft markets, requiring organizations to rethink program design, capital strategy and long-term resilience. Risk leaders who can adapt early gain a strategic advantage in securing capital, accelerating development and sustaining growth.

“The complexity of matching capital with risk continues to increase,” says Ciaran Healy, Global Captives Leader for Aon. “We are moving into a different risk financing landscape and clients will need partners that can combine judgment, experience, real-time insights and dynamic analytics. The traditional approaches are now less fit for purpose.”

Unleashing Capital and Capacity Through Alternative Risk Transfer

Alternative risk transfer (ART) solutions are playing a more significant role — not as a replacement for traditional insurance, but as a complementary mechanism to engineer insurability, align lenders and insurers, and unlock capacity.

ART solutions first gained traction during earlier hard market conditions, when organizations relied on them to manage difficult-to-insure or capacity-constrained risks. That remains true today; however, the current soft market conditions, buoyed by a benign 2025 hurricane season and record-high reinsurer capacity, provides provide an opportunity to build longer-term risk strategies.

“The current soft market could be short-lived. Businesses should be reevaluating their programs while market conditions are favorable,” says Guy Malyon, Strategic Broking Director for Aon in Europe, the Middle East and Africa. “One of the misconceptions is that ART solutions are purely a hard market play. That’s not the case anymore.”

Digital Infrastructure Risk Snapshot

How ART Solutions Work for Hard-to-Insure Risks: Digital Infrastructure

A Defining Capacity Challenge: Rapid expansion of digital infrastructure — accelerated by artificial intelligence (AI) and cloud demand — is creating exposures that traditional insurance markets face challenges in matching. By 2030, Aon expects global data center investment to be $5 trillion to $10 trillion, underscoring the scale of this challenge.

The concentration, scale and embedded energy systems of these modern campuses create structural constraints for insurers, shaping financing decisions, project timelines and lender expectations.

Why Traditional Insurance Structures Fall Short: Conventional indemnity programs can face limitations under the aggregation, complexity and value concentration of hyperscale developments. Reinsurers also face rising accumulation pressure across operators, regions and rapidly scaling portfolios.

Engineering Insurability Through ART: ART solutions give buyers some of the tools to reshape data center risk and create insurable structures where the market cannot meet demand. Key approaches include:

  • MFL-based program design
  • Zoned or segmented structuring
  • Captives
  • Insurance-linked securities
  • Parametric solutions
  • Acceptance of targeted residual exposures

ART structures also allow buyers to balance retained and transferred risk, align with lender expectations and unlock additional capital.

Putting ART Solutions to Work: Parametric as a Captive Backstop

Capability Overview Use Case

Putting ART Solutions to Work: Parametric as a Captive Backstop

A Florida client faced an inefficiently priced property program and was unwilling to take on additional risk solely through its captive. Aon designed a facultative parametric backstop between the captive and the parent and reinsured by a third‑party capital provider. The structure delivered a more efficient risk‑financing solution without increasing the client’s retained exposure. “The business was paying $6 million for its primary property coverages. We moved the primary to a captive, allocated $3 million of the total cost of risk, and added $25 million in parametric wind coverage,” says Colin Harper, Managing Director for Alternative Risk Transfer in North America. “This reduced reliance on traditional markets without adding risk.”

Where are the Next Emerging Data-Center Level Risks?

  • 01
    AI Infrastructure and Model-Performance Risk

    AI risks increasingly stem from model performance, bias and decision errors, not only cyber events. Insurers are beginning to underwrite the models themselves, introducing unfamiliar triggers and limited loss data. Systemic losses can occur when many firms use the same models or vendors.

  • 02
    Energy Transition and Next-Generation Infrastructure Risk

    Large-scale battery storage, hydrogen facilities and grid infrastructure introduce new fire, explosion and cascading outage scenarios that traditional models struggle to capture. These assets are capital-intensive and often co-located, creating aggregation risk and uncertainty for insurers.

  • 03
    Digital Supply Chain and Interdependency Exposure

    Increasing interdependency across suppliers, platforms and regions increases systemic disruption risk. Political risk, localization strategies and technology concentration increase systemic exposure. Losses often sit between traditional coverage lines.

  • 04
    PFAS and Emerging Chemical Liability

    Per- and polyfluoroalkyl (PFAS) litigation is accelerating, with U.S. settlements reaching $18 billion and potentially exceeding $100 billion.2 Insurers are tightening terms through coverage clarifications and exclusions. In the U.S., PFAS exclusions are mandated for most risks.

  • 05
    Mass Timber Construction Risk

    Mass timber supports sustainable, efficient construction and is key to green building. Yet water, moisture and mold remain core concerns, so many property insurers restrict capacity or avoid mass timber risks entirely.

Risk is Evolving Through Data — And Capital is Responding Differently

A Shifting Risk Landscape: The insurance market is more buyer-friendly than in recent years, but use of ART solutions continues to expand. Advances in modeling, diagnostics and data analytics are opening new pathways for investors to participate in risk, enabling clients to build more flexible, evidence-based risk financing strategies.

“ART solutions are just a risk mechanism and sometimes they can be complex,” says Aurelien Schwachtgen, Alternative Risk Transfer Leader for Aon in France. “Analytics validate the right mechanism for a client’s portfolio and decision making.”

Shifts are Reshaping Capital Behavior: Capital providers are increasingly central to large-scale project execution as insurance capacity tightens. Third-party reinsurance capital reached a new high of $124 billion at the end of Q3 2025, illustrating investors’ growing appetite alongside heightened caution of specific risks that carry a large-loss potential. These include nat cats, nuclear verdicts impacting a tightening U.S. excess casualty market, risk financing, AI and professional liability exposures.

The New Role of Risk Structuring: Risk structuring has become a financing tool in its own right. It addresses:

  • Legacy loan requirements
  • Incorporating structured retention strategies on multi-year basis
  • Captives providing credit-enhancing stability
  • ART solutions aligning insurance and lender expectations

Why this Matters for Clients: Aon’s integrated analytics and capital strategy capabilities enable clients to improve bankability and cost of capital, across a portfolio.

“We can see things in the data that we couldn’t see five years ago,” adds Ching. “Like behaviors, decisions and movements within the core corporation that indicate how they think about problems. We can match those insights with market expectations and pricing to build structures that are both practical and efficient for clients.”

Aon’s approach uses analytics by line of coverage and in portfolio. In most cases various lines of coverage perform to a statistical curve. When combined with other non-correlated risks, that creates a portfolio effect, similar to investment portfolios.

“Managing individual lines of coverage risk focuses on price, form and retention,” adds Ching. “Managing a portfolio focuses on overall risk volatility for the organization as risk managers tend to focus on price and CFOs focus on risk volatility.”

ART’s Evolution as Mainstream Risk Financing Tool

Organizations with advanced risk management strategies are increasingly considering how ART solutions can be used across their wider portfolio — using a blend of traditional and alternative solutions to optimize their risk financing strategy and cost of capital. Risk financing solutions include:

  • Insurance-Linked Securities: These are financial instruments linked directly to insurance risk, allowing investors to earn returns connected to the performance of insured events. Examples include catastrophe bonds and collateralized reinsurance, which provide capital to cover risks while enabling investors to diversify their portfolios. Demand has been high: Investors deployed a record $24.7 billion in cat bonds in 2025.3
  • Structured Risk Solutions: These can provide bespoke alternative capacity by incorporating, for example, multi-year terms and the hybrid characteristics of risk financing and risk transfer.

From Last Resort to Strategic Lever: How Structured Solutions Build Program Flexibility

  • 01
    Loss-Free Structured Insurance Layer

    After two major property losses, a global food company adopted a multi‑year structured solution with 80% of premium funding an experience account. Four years with no losses allowed the client to recover the unused balance, reducing cost by 75% and giving flexibility to reinvest or extend limits.

Other ART Solutions Contributing to Expansion

Captives can act as the cornerstone of an overall risk capital strategy, allowing organizations to access diverse risk capital, allocate premium strategically, improve risk management practices and gather valuable data.

“Insurers are lining up around captives and alternative risk solutions — a clear sign that capital is moving,” says Healy. “The traditional way of buying insurance is evolving. Captives are being used to retain risk, as they traditionally have, but are also being used as a platform for capital.”

Captives also provide an organization with the “housing” to become an underwriter of choice where advanced analytics (by line or portfolio) can determine a price difference between risk retention and transfer.

“The captive becomes a critical part of the placement but uses its strong understanding of the parent company’s risk to control, leverage and drive program design by defining the price point where a deal should be bound,” adds Ching.

Capability Overview Use Case

How Clients Are Using ART to Optimize Programs

New Capital Delivers for Waste Recycler Captive
A Northern European–based multinational with difficult‑to‑insure waste‑metal recycling operations relied heavily on its captive but faced shrinking coverage and rising cost due to limited market capacity and poor loss experience. Using analytics and a capital‑agnostic review, Aon showed how the captive could be used to access new forms of capital, not just retain risk. Structured reinsurance introduced competition for existing capacity and reframed the captive’s role. Blending conventional and alternative capital in a layered structure improved volatility management and gave the client greater control over risk‑financing outcomes, gaining senior‑leadership attention.

Parametric provides organizations with a different way to strategically think about risk mitigation, especially in catastrophe-prone areas where capacity and terms are restricted and rates are adverse.

“What parametric insurance cares about is a fortuitous weather or natural catastrophe event occurring, at a specific location, of a specified severity and during the policy period. So long as those are variables are satisfied then the coverage is triggered,” says Harper.

An agricultural company selling seed introduced an option for producers to purchase yield hedge protection via a parametric solution. If the seed underperforms, the payout provides stability to producers while helping the organization strengthen retention and capture more market share.

Reframing Risk Capital: What Organizations Need to do Next

  1. Understand how risk behaves and where capacity is tightening.

    Organizations need a clearer view of exposure drivers and capital constraints. Diagnostics, benchmarks, Aon’s Risk Analyzers and market‑intelligence tools help identify when traditional capacity may underperform and where alternative capital can create better outcomes.
  2. Address capital gaps early — especially in digital infrastructure.

    Data center and other capital‑intensive projects face constraints that influence timelines, lender expectations and bankability. The expanded Data Center Lifecycle Program shows how coordinated, multi‑line support can reduce friction across construction and operations.
  3. Reassess long‑standing structures using analytics.

    Analytics often show that reallocating budget toward structured or parametric solutions provides more reliable triggers, quicker access to capital and stronger post‑event continuity — especially where traditional excess layers rarely respond.
  4. Integrate data, underwriting insight and capital‑market intelligence.

    Bringing these elements together helps organizations design risk‑financing strategies that reduce volatility, respond to capacity dynamics, and support long‑term resilience and growth.

Organizations evaluating how capacity, capital or program structure may influence future decisions can work with Aon to compare options, understand how different forms of capital respond, and identify structures that best support resilience and financing objectives.
