Insurers, Brokers React to Data Center Boom

Why It Matters

The surge reshapes underwriting capital, creates new revenue streams, and forces insurers to address unprecedented scale and geographic risk in the digital infrastructure sector.

Key Takeaways

• Aon boosted data center insurance capacity to $3.5 billion in 2024
• FM Intellium raised limits to $5 billion for large‑scale projects
• Marsh’s Nimbus facility now offers $2.7 billion in data center coverage
• Zurich launched a $2 billion builders‑risk product for operational centers
• Swiss Re forecasts data‑center premiums exceeding $24 billion by 2030

Pulse Analysis

The data‑center construction wave, accelerated by generative AI, is redefining the risk landscape for insurers. Projects that once cost $3 billion now command contract values of $25‑50 billion, demanding far larger insurance limits and more integrated coverage solutions. Insurers such as Aon, FM Intellium, and Marsh have responded by injecting billions of dollars in capacity and consolidating policies into single‑facility structures, simplifying administration for developers and reducing gaps between construction, cargo, and operational phases.

Beyond sheer size, the geographic footprint of new facilities raises acute catastrophe concerns. Swiss Re’s analysis shows roughly 40 % of U.S. data‑center capacity sits in high‑tornado zones, while coastal sites face hurricane and flood threats. This exposure is prompting carriers to develop tailored products—Zurich’s Data Center Project Guard combines builders risk, parametric, and operational coverage up to $2 billion—to help clients transition smoothly from build‑out to day‑to‑day operations. The shift toward integrated risk‑financing reflects a broader industry trend of offering end‑to‑end solutions rather than fragmented policies.

For the broader market, the rapid scaling of insurance capacity signals a lucrative, yet volatile, growth avenue. Premiums tied to digital infrastructure are projected to more than double by 2030, attracting capital but also demanding sophisticated modeling and re‑insurance structures. Companies that can balance scale, speed, and nuanced catastrophe modeling will capture market share, while those lagging may face capacity shortfalls as developers push for ever‑larger, AI‑driven facilities. The evolving landscape underscores the strategic importance of insurance in sustaining the backbone of the modern digital economy.
