AI will drive greater than 50% of worldwide information heart capability and greater than 70% of income alternative, in line with Omdia’s Analysis Director for Digital Infrastructure Vlad Galabov, who mentioned large productiveness good points throughout industries pushed by AI will gasoline this progress. Talking throughout Information Heart World 2025’s analyst day, Galabov made a lot of different predictions concerning the trade:
NVIDIA and hyperscalers’ 1 MW-per-rack ambitions most likely gained’t materialize for an additional couple of years till engineering innovation catches as much as energy and cooling calls for.
By 2030, over 35 GW of information heart energy is anticipated to be self-generated, making off-grid and behind-the-meter options not non-obligatory for these seeking to construct new information facilities, as many utilities battle to ship the mandatory energy.
Information heart annual capital expenditure (CAPEX) investments are anticipated to achieve $1 trillion globally by 2030, up from lower than $500 billion on the finish of 2024.
The strongest space for CAPEX is bodily infrastructure, corresponding to energy and cooling, the place spending is growing at a charge of 18% per yr.
“As compute densities and rack densities climb, the investment in physical infrastructure accelerates,” Galabov mentioned. “We expect a consolidation of server count where a small number of scaled-up systems are preferred to a scaled-out server strategy. The cost per byte/compute cycle is also decreasing.”

Information heart energy capability explodes
Galabov highlighted the explosion AI has brought on in information heart energy wants. When the AI wave started in late 2023, the put in capability of energy in information facilities worldwide was lower than 150 GW. However with 120 kW rack designs on the speedy horizon, and 600 kW racks solely about two years away, he forecasts almost 400 GW of cumulative information heart capability by 2030. With new information heart capability additions approaching 50 GW per yr by the top of the last decade, it gained’t be lengthy earlier than half a terawatt turns into the norm.
However not everybody will survive the wild west of the AI and DC market. Many startup DC campus developments and neoclouds will fail to construct a long-term enterprise mannequin, as some lack the experience and enterprise savvy to outlive. Don’t concentrate on a single supplier, Galabov cautioned, as some are more likely to fail.

AI drives liquid cooling innovation
Omdia’s Principal Analyst Shen Wang laid out the cooling repercussions of the AI wave. Air cooling hit its restrict round 2022, he mentioned. The consensus is that it could actually ship as much as 80 Watts per cm2, with just a few suppliers claiming they’ll take air cooling larger.
Past that vary, single-phase direct-to-chip (DtC) cooling — wherein water or a fluid is taken to chilly plates that sit instantly on prime of laptop chips to take away warmth — is required. Single-phase DtC can go as excessive as 140 W/cm2.
“Single-phase DtC is the best way to cool chips right now,” Wang mentioned. “By 2026, the threshold for single-phase DtC will be exceeded by the latest racks.” That’s when two-phase liquid cooling ought to start to see a ramp-up in adoption charges. Two-phase cooling runs fluids at larger temperatures to the chip, inflicting them to show to vapor as a part of the cooling course of, thereby growing cooling effectivity.
“Advanced chips in the 600 watt and above range are seeing the heaviest adoption of liquid cooling,” Wang mentioned. “By 2028, 80% of chips in that category will utilize liquid cooling, up from 50% today.”
