The Risk Behind the Data Centre Build-Out

Aon published commentary this week on the capital challenge created by the global expansion of digital infrastructure. The scale is striking. By 2030, global data centre investment is expected to reach somewhere between $5 trillion and $10 trillion. The concentration of value in these assets - hyperscale campuses with embedded energy systems, accumulated across operators and geographies is creating exposures that traditional insurance markets are finding increasingly difficult to absorb.

Aon published commentary this week on the capital challenge created by the global expansion of digital infrastructure. The scale is striking. By 2030, global data centre investment is expected to reach somewhere between $5 trillion and $10 trillion. The concentration of value in these assets - hyperscale campuses with embedded energy systems, accumulated across operators and geographies — is creating exposures that traditional insurance markets are finding increasingly difficult to absorb.

Aon's conclusion

Aon's conclusion is that alternative risk transfer and insurance-linked securities are no longer supplementary tools for managing this exposure. They are becoming structural requirements for whether major projects can proceed at all. Insurance capacity is now a factor in project bankability, loan conditions and deal execution. The risk financing decision is moving upstream into the capital strategy.

What makes this more than a capacity story is the analytics dimension. Aon notes that advances in modelling, diagnostics and data analytics are opening new pathways for investors to participate in risk, enabling more flexible, evidence-based risk financing strategies.

The implication is clear: the quality of the risk intelligence sitting underneath an ILS structure is becoming as important as the structure itself. Investors participating in these markets need to trust not just the model outputs but the data and reasoning that produced them.

Why this matters

This matters for the reinsurance market in Bermuda and London, where the appetite for digital infrastructure risk is real but the analytical frameworks are still catching up with the exposure complexity. Third-party reinsurance capital reached a new high of $124 billion at the end of Q3 2025. The question is not whether that capital will deploy into emerging digital risk classes. It is whether the intelligence infrastructure supporting those deployments is fit for the purpose.

The firms building durable positions in this market will be the ones that can answer that question clearly. Evidence-based risk financing requires evidence. That means context, provenance, and the ability to trace a conclusion back to the data and reasoning that produced it. That capability is not a feature of conventional risk platforms. It is an infrastructure decision.
