Hyperscale data centers are creating concentrated physical assets worth tens of billions of dollars each, pushing the insurance industry toward catastrophe bonds as a potential solution — though the first dedicated deal is still 12 to 18 months away, experts say.
The rapid expansion of hyperscale data centers is creating tens of billions of dollars in concentrated physical assets — and an insurance problem that traditional markets may be unable to absorb alone, according to industry experts.
A single hyperscale campus can carry between $20 billion and $30 billion of insurable value, a figure that dwarfs the scale of conventional coverage mechanisms. For context, the entire catastrophe bond market currently has roughly $66 billion outstanding — meaning one campus alone could represent nearly a third of that total.
"You cannot solve that with the traditional market alone. The arithmetic doesn't work, and that's why this ultimately ends up in the capital markets," said Ethan Powell, principal and chief investment officer of Brookmont Capital Management, a Texas-based firm with more than $1 billion in assets under management.
Catastrophe bonds, or CAT bonds, are financial instruments first created in the 1990s that allow insurers and reinsurers to transfer the risk of large losses from extreme events to capital market investors. In exchange for holding the risk, investors receive equity-like returns — though they face the prospect of losing some or all of their principal when a covered catastrophe triggers a payout.
Despite the apparent fit, Powell noted that no data center risk has yet reached the CAT bond market directly. "What's happening right now is one layer upstream, through quota shares, sidecars and new reinsurance facilities, as reinsurers wrestle with how to price data center risk and find enough capacity to cover it," he said.
Powell nonetheless expects the first dedicated data center CAT bond deal to emerge within 12 to 18 months, most likely structured as a traditional property catastrophe tranche covering risks the insurance-linked securities market already knows how to model — primarily hurricanes and earthquakes. The calculus is shifting as more data centers are built in Texas and Arizona, moving exposure away from coastal storms and toward severe weather events such as tornadoes and hail.
The harder risks to price remain fire, water damage, power outages, and business interruption. As those perils become better modeled and structures more standardized, Powell said, the dedicated market is likely to follow.
The broader CAT bond market is on pace for a record year regardless, with issuance reaching $18.9 billion so far in 2026 as first-time buyers enter what was long considered a niche corner of insurance finance.
Steve Evans, owner and editor-in-chief at specialist data provider Artemis.bm, said insurers and reinsurers increasingly recognize the value of catastrophe bond structures for their multi-year format and diversifying capacity. He noted there are "no signs of investor interest waning," even as spreads move closer to historical averages, adding that well-capitalized reinsurance and insurance-linked securities markets have made buyer conditions "even more favourable."
The risk profile for data centers extends beyond natural disasters. Hanni Ali, founder and CEO of Bermuda-based Radix ILS, flagged sabotage, war, and cyberattacks as additional exposures that lenders to data centers may eventually seek to transfer through the CAT bond market.
"I think the interesting thing with data center risk is that we've got an accumulation of physical infrastructure assets — and I'd caution that certainly with the ongoing war in the Middle East, we've also got to recognize that this represents critical infrastructure," Ali said.
Evans cautioned that the CAT bond market still has significant ground to cover before it can support the insurance limits demanded by the scale of current data center development, and that which perils get covered — and in what formats — remains unsettled.
As AI infrastructure investment accelerates and asset concentrations deepen, capital markets will face mounting pressure to develop pricing frameworks that traditional insurers have not yet been asked to build.
