Marsh Launches $10 Billion Data Center Insurance Exchange

News Desk: Marsh has rolled out a new property insurance exchange called Stratus that can deliver as much as $10 billion of capacity in a single placement for the operational risks of data centers and other digital infrastructure. The facility, announced this week, targets the global exposures of U.S.-domiciled companies and brings together 30 traditional and alternative capital providers who will review each risk on its own merits.

According to coverage in Insurance Business magazine, Stratus is built specifically for the period after construction ends, when the facilities are live and generating revenue. It sits alongside Marsh’s earlier Nimbus facility, which focuses on the building phase and has already grown to roughly $2.7 billion in capacity. Clients can use the two facilities separately or together depending on where their projects stand.

Joe Macejak, who leads U.S. property digital infrastructure work at Marsh Risk, said the exchange is meant to raise the quality and speed of these complex operational placements. Marsh indicated that more than $4 billion in capacity has already been verbally committed, after the broker approached around 80 carriers and syndicates worldwide. The initial focus is pure property cover, with plans later to add inland marine, cyber and casualty options along with data analytics and advisory support.

The timing reflects the sheer scale of current data-center development. Individual campuses can carry $15 billion to $20 billion in combined property, equipment and business-interruption exposure, and the market has struggled to assemble enough traditional capacity for the largest operators. Some hyperscale firms self-insure large portions of their risk, so Stratus is expected to appeal both to them and to smaller operators still seeking conventional market protection.

By creating a structured exchange rather than a one-off placement process, Marsh aims to help capital providers manage aggregation and diversification more effectively during the operational stage. Industry observers note that the facility arrives as the insurance market continues to adapt to the rapid growth of AI-driven computing needs and the physical infrastructure that supports them.
