Data centers today, driven by growth and scale, concentrate enough value for a single event to create a portfolio-level loss. Re/insurers and captives that understand and manage aggregation exposure will be better positioned to sustain capacity and support long-term sector growth.

Key Takeaways

• Rising total insured values across data center campuses within the same location or region are increasing the potential for multi-site, multi-policy losses, putting pressure on re/insurance capacity.
• Limited visibility of interconnected exposures creates a gap in how data center accumulation risk is quantified, priced and managed.
• Stronger accumulation risk management can improve underwriting confidence, support more resilient program structures and enable sustainable capital deployment.
