Capacity constraints likely as annual data centre investment set to top £230bn

The burgeoning data centre insurance market represents a “huge growth opportunity”, with some $10bn (£7.5bn) in new insurance premiums forecast for 2026.

The figure represents a vast new risk pool, dwarfing the annual premiums of approximately $5bn (£3.8bn) seen in the global aviation industry.

This insight comes from a new report by S&P Global Ratings, released today (14 April 2026), which highlighted that a complex ecosystem of developers, builders, utility providers and equity investors will offer multiple vectors for insurers to provide cover.

And with annual global investment in data centres likely to surpass $300bn (£230bn) by 2027, the opportunities for (re)insurers will continue to grow.

However, S&P Global Ratings highlighted that capacity constraints are likely to become a limiting factor for insurer involvement, due to the high insurable value of individual projects.

Capacity constraints

Charles-Marie Delpuech, credit analyst at S&P Global Ratings, said: “We expect capacity constraints to limit the industry’s ability to fully insure these hyperscale data centre projects, as total insurable values reach $20bn (£15bn) to $30bn (£22.5bn) per location.

“How (re)insurers manage concentration and aggregation risk due to the colocation of high-value assets and the interconnectedness of risks through the presence of multiple stakeholders will be a key consideration in our credit rating analysis.”
