Marsh has established a global Digital Infrastructure Contract Advisory Group to assist clients in managing service contracts across the lifecycle of their data center, fiber network, and AI platform assets.
The launch comes as data center investment enters what analysts describe as a "supercycle." According to Moody's 2026 outlook, global data center investment is expected to reach $3 trillion over the next five years, with spending by six US hyperscalers – Microsoft, Amazon, Alphabet, Oracle, Meta, and CoreWeave – hitting nearly $400 billion in 2025.
JLL's 2026 Global Data Center Outlook forecasts that nearly 100 GW of new capacity will be added by 2030, doubling the global footprint.
Digital infrastructure projects typically involve multiple contracts, including service-level agreements and power purchase agreements, each containing specific insurance and risk-transfer provisions. The scale of operations and rapid technological changes can make these agreements difficult to review and manage.
The new advisory group consists of former contract attorneys, risk managers, and insurance specialists. The team provides contract review and negotiation support during the acquisition, construction, and operational stages of digital infrastructure projects.
Mike Mathews, global digital infrastructure leader at Marsh, said contract reviews require specialized knowledge, coordination, and considerable time, which can be challenging for clients who may lack dedicated risk management teams.
"Our team of experienced contract specialists alleviates this burden for clients, delivering peace of mind while also enabling them to move at pace," Mathews said.
Mathews was appointed to the newly created role in December 2025. He joined Marsh in 2020 as a managing director focused on digital infrastructure clients, bringing more than 25 years of experience advising companies in sectors including data centers, wireless networks, and digital mining.
Marsh is not alone in targeting this segment. Rival Aon launched its Data Center Lifecycle Insurance Program in 2025 and expanded it to $2.5 billion capacity in January 2026. Like Marsh's Nimbus facility – which was expanded earlier this week – Aon's program integrates construction, cyber, cargo, and operational risks into a single coordinated solution.
Marsh's new advisory group – focused specifically on contract review and negotiation – appears designed to differentiate its offering by addressing a pain point earlier in the deal process.
The group's services include aligning contract language with insurance requirements, identifying coverage gaps, and securing insurance for potential claims.
Nimbus first launched in June 2025 as a dedicated insurance product for data center construction. The facility is currently being deployed on projects in the US, UK, and the Netherlands, and provides coverage for delay in start-up and business interruption.
According to JLL, global data center construction costs rose from $7.7 million to $10.7 million per megawatt between 2020 and 2025, with a further 6% increase forecast for 2026 – as underscoring the growing insurance exposures that both Marsh and Aon are seeking to address.
