With growing capacity demands within AI and other cloud computing services leading towards a surge in data centers, this rapid expansion also presents a clear role for insurance-linked securities (ILS) and the capital markets, according to broker Aon.
“The pace and scale of capital investment in data centers, coupled with accelerating third‑party financing and debt structures, is set to dramatically increase demand for insurance: Between 2026 and 2030, cumulative global insurance premiums associated with data centers are estimated to be $134 billion,” the broker said.
Aon highlights that a disciplined strategy in this space is fast becoming a differentiator.
“For insurers, a disciplined data center strategy is fast becoming a differentiator. Insurers must determine where they want to participate, develop the necessary underwriting capabilities and define their net appetite and reinsurance requirements. For reinsurers, there are significant opportunities to support higher gross capacity deployment and provide excess-of-loss and quota share structures calibrated to data center dynamics,” the firm said.
A key component of this capacity will likely stem from the capital markets.
“With insurance demand in excess layers escalating, there is a clear role for alternative and long‑term capital providers— including ILS, asset managers, life insurers and sovereign wealth funds—to complement traditional reinsurance capacity and support sustainable growth in the sector,” Aon explained.
Ultimately, the convergence of surging demand and finite traditional capacity positions the data center sector as a prime frontier for capital market innovation.
By bridging the protection gap through structured ILS instruments, investors can gain access to a diversifying asset class that is decoupled from standard market cycles.
This became a topic of conversation at our recent ILS NYC 2026 conference, where panellists described the need to segment out different exposures from across the data center construction built and life cycle, in order to create opportunities that can be appealing to third-party investors.
All of the major capital market brokers are understood to be exploring how to bring the capital markets to the data center build-out opportunity, with discussions said to be ongoing around what insurance-linked securities structures may be appropriate, as well as whether the property catastrophe components of these massive, high-value commercial real-estate sites could be large enough to warrant catastrophe bonds.
Aon’s CEO recently gave a good idea of the scale of the opportunity, as Greg Case said Aon’s “reinsurance team recently designed and placed the first ever data centre specific treaty, delivering a solution that aligns up to $5 billion of capital through the insurance value chain behind a single leading insurer. And we’re actively engaged with several others to help them expand and strengthen their capabilities to provide capacity for clients.”
However, Aon emphasised in its recent report that capturing this opportunity requires a shift toward technical specialisation.
To support higher limits and price risk profitably, re/insurers must prioritise deep insights into data center-specific engineering, modern resiliency features, and evolving operational best practices.
To manage this at scale, the industry must also evolve its approach to aggregation and tail risk. By utilising purpose-built aggregation tools and tail-risk views, that account for shifting energy and climate-related exposures, carriers can better align their portfolios with lender requirements. This approach can help ensure that net appetites, attachment points, and layering strategies are strategically positioned to withstand systemic shocks.
“Data centers sit at the core of the digital economy, and their risk financing needs are scaling faster than the existing insurance capital base. Insurers and reinsurers that build a dedicated, resilient data center strategy—anchored in robust underwriting, tailored reinsurance programs and access to diverse capital sources—are well positioned to capture outsized, long‑duration growth while helping to underpin global digital infrastructure,” Aon added.
Our sister publication Reinsurance News covers developments in insurance and reinsurance risk transfer for data centers in more depth, with some of these initiatives gaining meaningful scale where capital markets support may be required.
