Marsh Expands Dedicated Data Center Insurance Facility to $2.7 Billion Amid AI-Driven Demand

Marsh Expands Dedicated Data Center Insurance Facility to $2.7 Billion Amid AI-Driven Demand January 26, 2026 The global boom in artificial intelligence and cloud computing is driving unprecedented demand for large-scale data center construction, creating complex new risks that require specialized insurance solutions. In response, Marsh, the world’s leading insurance broker and risk advisor, has significantly expanded its dedicated facility for this critical infrastructure sector. Marsh announced it has increased the capacity of its Nimbus insurance facility, raising the available coverage limits to $2.7 billion for major data center construction projects. The expansion, which includes enhanced protection for delays in start-up and business interruption, comes less than a year after the product's initial launch in June 2025. The facility is designed to cover projects across key markets including the United States, the United Kingdom, Canada, Europe, Australia, and New Zealand, and is currently being deployed on active developments in the U.S., UK, and the Netherlands. The substantial capacity is drawn from a panel of A-rated insurers from both Lloyd’s and the broader company markets. Mike Mathews, Global Digital Infrastructure Leader at Marsh, linked the move directly to the technological transformation underpinning the sector. "Demand for more powerful and efficient data centers is accelerating technological innovation, particularly around AI and machine learning, which will revolutionize the way we live and work and reshape economic landscapes over the next decade," Mathews stated. He added that Marsh is leveraging its expertise across capital management, construction, power generation, and operational resilience to help clients strengthen their project delivery and long-term sustainability. This strategic expansion positions Marsh at the forefront of the specialized data center insurance market, a segment seeing intense activity. The move notably follows rival Aon's recent decision to add $1 billion to its own data center program, bringing its total capacity to $2.5 billion in January 2026. The escalating financial commitments from leading brokers underscore the immense scale, capital intensity, and risk profile of modern digital infrastructure projects, signaling a critical evolution in risk transfer mechanisms for the backbone of the global digital economy.
