Aon raises capacity for data center program

Aon on Wednesday raised the capacity for its data center lifecycle insurance program by another $1 billion to $3.5 billion.

The broker also expanded the program to include coverage for existing data centers coming off the first year of operations, extending support to existing data center assets beyond construction and commissioning.

The program includes up to $3.5 billion in coverage for construction all risks, delay in start-up, or DSU, and operational property damage/business interruption, and up to $400 million of cyber and technology errors and omissions coverage, including non-damage cyber DSU and ransomware protection, the broker said in a statement.

It also offers up to $200 million third-party liability globally, including $100 million in U.S. excess capacity, and up to $500 million project cargo and transport insurance.

Risk engineering and cyber impact modeling are available through Aon’s global risk consulting team.

Aon last raised capacity for the facility by $1 billion to $2.5 billion in January. The facility was launched in June 2025.

The latest expansion “reflects accelerating global investment in cloud computing, artificial intelligence and hyperscale infrastructure,” Aon said.

Insurers and brokers have moved to provide integrated coverages and additional capacity to support the AI-inspired surge in data center construction.
