The buildout of AI data centers and global energy infrastructure could generate about $200 billion in cumulative commercial insurance premiums between 2026 and 2030, according to Swiss Re Institute. The forecast, published September 8 in the institute's latest sigma report, signals a structural shift in demand for property, business interruption, and liability coverage as capital expenditures surge into the trillions.
Global energy investment alone is expected to reach $3.4 trillion in 2026, with roughly $2.2 trillion directed toward renewables, nuclear, grids, storage, low-emissions fuels, efficiency, and electrification. At the same time, the five largest U.S. hyperscalers are projected to invest nearly $800 billion in AI-related capital expenditures in 2026, and global data center capex estimates now exceed $1 trillion.
Data centers become strategic infrastructure
Swiss Re Institute said these investments are transforming data centers from information technology assets into strategic infrastructure requiring substantial electricity, telecommunications, cooling systems, and cloud connectivity. Some AI data center campuses, including computing equipment, can cost up to $50 billion to replace - a scale that fundamentally changes the underwriting conversation.
The report, titled "Time to build: Expanding the frontier of insurability for the capex super-cycle," frames the opportunity alongside a clear warning about accumulation risk. "Limited operating histories for large infrastructure projects can make loss frequency and severity difficult to quantify," the institute said, adding that accumulation and extreme loss potential can complicate diversification and capacity deployment.
Where risk concentrates geographically
Texas and Virginia account for more than 40% of current and planned U.S. data center capacity. More than a quarter of that capacity sits in areas that could experience at least three days of large hail annually, and about 40% is in regions facing at least three tornado days each year. The clustering is not unique to the U.S. In Taiwan, roughly 88% of semiconductor fabrication plants are located in extreme to very extreme seismic-risk zones, while the country plays a central role in global semiconductor supply chains.
Swiss Re Institute identified four structural drivers of risk accumulation: large individual assets, geographic clustering, supply chain dependencies, and shared physical and digital networks. Specialized equipment introduces additional bottlenecks. High-voltage transformers, for example, can have lead times of several years, potentially extending project delays and business interruption losses well beyond what standard modeling anticipates.
Capital is available - deploying it is the challenge
The institute said the primary constraint is not the availability of insurance capital but the ability to deploy it confidently against increasingly complex exposures. While construction risks are relatively well understood, commissioning high-value equipment can introduce greater property, business interruption, contingent business interruption, and liability exposures. In some cases, financial losses from an interruption can exceed physical damage.
Swiss Re Institute pointed to engineering-led underwriting, improved modeling, and accumulation management as tools that can help insurers better understand these risks. The report also emphasized that insurers, reinsurers, and capital markets can share large exposures across multiple balance sheets.

Why this matters for insurance professionals
The $200 billion premium estimate represents a tangible pipeline, not a theoretical projection. Underwriters and brokers who build technical fluency around data center construction, energy project commissioning, and supply chain interdependencies now will be positioned to capture that flow. The risk is that accumulation modeling lags behind the speed of capital deployment - meaning the difference between profitable growth and outsized loss years will come down to how well carriers map geographic clusters, single points of failure, and contingent business interruption exposures before they bind coverage.
