Water Is the New Oil, Says Goldman Sachs

Goldman Sachs flags smart water infrastructure as a top emerging asset class, with AI data centers driving unprecedented freshwater demand

4 May 2026

Goldman Sachs has identified smart water infrastructure as one of the most compelling emerging asset classes in global markets, citing the rising water demands of artificial intelligence data centres as the key driver of that assessment.

In a formal investment outlook published in April 2026, the bank drew a direct line between AI expansion and freshwater stress. A single large data centre can draw up to 5 million gallons of water per day, a volume comparable to the daily consumption of a town of 50,000 people. The burden is compounded by semiconductor manufacturing and power generation, both concentrated in water-scarce states such as Arizona.

Goldman identified four areas with the clearest investment case: water recycling and filtration technology; software that reduces water use in agriculture and industry; AI-driven flood risk management; and the modernisation of ageing distribution networks. In many developed markets, water pipes are 40 to 50 years old, and the transition to smart metering and real-time leak detection is accelerating.

Market data supports the argument. The global digital water sector was valued at roughly $7.18bn in 2025 and is forecast to exceed $22bn by 2035. The segment covering internet-connected water management systems alone was worth more than $13bn in 2026, growing at over 14 per cent annually.

The risks are real. US federal funding for water infrastructure is due to expire in September 2026, and communities in several states have pushed back against data centre development on water-use grounds. Smaller utilities, with limited capital reserves, may struggle to keep pace as digital investment widens the gap with larger operators.

Goldman's broader argument is that early movers stand to benefit as scarcity deepens and AI infrastructure scales. For institutional investors, the question is shifting from whether water technology matters to how quickly the market will price that in.
