Aon sees “sustained monumental” opportunity in data centers
Aon used its Q3 2025 earnings call to report 7% organic growth and a 26.3% margin — but most of the conversation focused on data centers.
The company described AI-fueled cloud infrastructure as a long-term, trillion-dollar insurance opportunity that it aims to organize capital around.
CEO Greg Case said global data center spending could surpass $2 trillion in the next few years, with more than $10 billion in new premium volume expected in 2026.
“In addition, advancements in AI are surging demand for cloud infrastructure and are fueling unprecedented investment in data center construction with CapEx estimated to exceed $2 trillion globally over the next several years. These technological developments are not only reshaping physical infrastructure but also amplifying cyber and operational risk. Active risk management in this area has become a strategic necessity and traditional approaches alone aren’t sufficient to cover this risk. With connected risk capital and human capital capabilities, we’re truly uniquely positioned to guide clients through a complex environment, access capital, unlock value and build resilience.”
Aon has already placed nearly $30 billion in coverage for a top hyperscaler, spanning both operational and under-construction sites.
When asked if the $30 billion in coverage represented a one-off for the quarter, CEO Gregory Case replied, “It really doesn’t.” He added:
“I just give you an example that this isn’t conceptual. It’s happening now. It’s also an interesting observation. We have an opportunity as an industry to step up and really make a difference here. But irrespective of what we do, these are happening. The investments are being made, and it’s quite substantial. So I just wanted to provide a very concrete example of where it’s — where something is sort of ongoing. But also think about the data center that we actually provided coverage on in that specific example. That was, by the way, part build. And in part, they have ongoing data centers in which actually help them understand how to think about the business continuity differently. And so for us, that is an ongoing effort. Again, back to why this is so unique. It’s not just the build, it’s the ongoing operation and then the innovation. And that means this is not just a monumental opportunity. This is a sustained monumental opportunity, which is one of the reasons we’re so excited about it.”
