Forecast and key figures
MarketsandMarkets says the market for fluids used in immersion cooling of data centers will expand at a compound annual growth rate of 24.8% between 2026 and 2033. The report, titled "Data Center Immersion Cooling Fluids Market - Global Forecast to 2033", covers market size data for the years 2022 to 2033 and runs to 254 pages, with 277 data tables and 61 figures.
North America is projected to grow fastest, at a CAGR of 26.6% in value terms. By data center type, the AI/ML segment is expected to register the highest CAGR, at 27.0%. In 2025, synthetic fluids accounted for a 57.0% share by value, while single-phase cooling held the largest technology share, 83.0% by volume.
Why demand is rising
According to MarketsandMarkets, demand is driven by AI, ML and HPC workloads that generate heat loads unsuitable for traditional air cooling. The firm says immersion cooling supports thermal management in hyperscale, edge and colocation data centers by improving energy efficiency, reducing water usage and enhancing system reliability.
The report lists several opportunities: the growing installation of AI-based mega data centers, rising demand for energy-efficient cooling, pressure on operators to lower their carbon footprint, and increasing interest in environmentally friendly fluids such as PFAS-free and bio-based options.
On technology, the report describes single-phase cooling as cost-effective and operationally simple. It involves no fluid boiling or phase change, which the firm says reduces system complexity and maintenance needs. A stable dielectric liquid absorbs heat and carries it to an external heat exchanger, which makes the approach easier to implement and scale. Synthetic fluids, the report says, offer superior thermal conductivity, oxidation stability and dielectric strength, along with low volatility and reduced maintenance needs.
For AI/ML data centers, the report points to GPU and TPU clusters used for deep learning, inference and generative AI, where conventional air cooling often falls short.
Players and investment
MarketsandMarkets names Shell plc (UK), The Chemours Company (US), Exxon Mobil Corporation (US), The Lubrizol Corporation (US) and Castrol Limited (UK) as star players, citing their market share and product footprint. Zhejiang Noah Fluorochemical Co., Ltd. (China), Fluorez Technology Inc. (Taiwan) and AMER TECHNOLOGY CO., LTD. (China) are highlighted among startups and SMEs with strong positions in niche areas. The wider list of key players also includes FUCHS SE, Submer, Green Revolution Cooling, Honeywell International Inc., Dow Inc. and TotalEnergies, among others.
The report describes investment as episodic. Funding rose from USD 43.0 million across three deals in 2020 to USD 750.0 million from one deal in 2021, then moderated to USD 240.0 million across four deals in 2022 and fell to USD 25.3 million from one deal in 2023. In 2024 it rebounded to USD 687.7 million across four deals. MarketsandMarkets says this pattern reflects a small number of large transactions rather than steady capital deployment.
The report also cites the Uptime Institute, which noted that direct liquid cooling attracted significant investment during 2024 to 2026 as AI training clusters increased rack power and thermal loads.
What it means for the market
The figures are a forecast from a market research firm, not measured results. They point to a still small segment, at USD 0.23 billion in 2026, that the firm expects to grow quickly as server power densities rise. MarketsandMarkets also sees revenue shifting toward higher-performance dielectric fluids able to support dense AI and HPC environments. For fluid suppliers and data center operators, the report suggests that performance and sustainability credentials, including PFAS-free and bio-based formulations, will matter in purchasing decisions.
