Vertiv Liquid Cooling 2026, $7 B Market, Microsoft Alignment

Closed-Loop Cooling Mandates, NC Proposes SB 730, Affects $4.07 B Market and 5+ County Moratoriums (2026)

$4.07 B Market Shift, Vertiv Capitalizes on Data Center Cooling Regulation

The escalation of local moratoriums and state-level legislative proposals in North Carolina during 2026 marks a fundamental shift, moving the data center industry from an era of unchecked, incentive-driven growth to one constrained by resource availability and social license. This pivot, driven by acute water stress and community opposition, directly alters the economic and operational calculus for data center development, creating significant risk for legacy assets while accelerating the adoption of water-efficient technologies.

• Between 2021 and 2024, regions like North Carolina actively courted data center investment with tax exemptions and minimal environmental oversight. The landscape reversed in early 2026 as grassroots movements and drought conditions converged, leading to a wave of development moratoriums enacted or considered by at least five municipalities, including Durham, Apex, and Chatham County, to study the industry’s resource impact.
• The strain became quantifiable as reports revealed single large data centers can consume between 1 million and 5 million gallons of water per day, a figure that prompted severe public and regulatory scrutiny when central North Carolina faced drought and Stage 1 water restrictions in April 2026.
• This backlash culminated in the advancement of a state-level bill (SB 730) in May 2026 that proposes to ban water-intensive open-loop cooling, eliminate local financial incentives, and remove state sales tax exemptions on electricity for data centers, fundamentally rewriting the rules for market entry and operation.
• The lack of a comprehensive state-level water-use permitting system in North Carolina, a key factor that previously attracted development, became a primary source of public distrust and a catalyst for the stringent proposed regulations, which include mandatory reporting for energy and water consumption.

Vertiv & n Vent, $7 B Liquid Cooling Market Growth From AI Demand (2026 to 2029)

Regulatory pressure to abandon water-intensive cooling is catalyzing investment into the advanced liquid cooling market, which was already on a high-growth trajectory due to the thermal demands of AI hardware. Multiple market analyses project a compound annual growth rate exceeding 20%, transforming a technological option into a compliance necessity and creating a significant, non-discretionary market for specialized equipment providers.

• The global data center liquid cooling market is set to expand rapidly, with one forecast projecting growth from $4.07 billion in 2026 to $27.65 billion by 2033, reflecting a CAGR of 31.5%. Other estimates place the market size at $6.77 billion in 2026.
• This growth is a direct result of the thermal challenges posed by AI, which increases the power density of server racks beyond the efficient capacity of traditional air-cooling methods. The North Carolina legislation serves as a powerful accelerant to an already existing technology adoption cycle.
• Technology providers with established portfolios in liquid cooling are positioned as the primary beneficiaries. Companies like Vertiv, n Vent Electric, and Schneider Electric are expected to capture significant market share as the regulations create a captive, billion-dollar market for their closed-loop and direct-to-chip cooling solutions. Dell’Oro Group forecasts the liquid cooling market will approach $7 billion by 2029, explicitly linking this growth to AI deployments.

North Carolina vs US, Vertiv Faces New Geographic Regulatory Risk

While the AI-driven data center expansion is a national phenomenon, North Carolina has emerged in 2026 as the primary geography for regulatory and community-driven backlash, setting a potential national precedent for how other water-stressed states will manage the industry’s resource appetite. This creates a fragmented regulatory map where North Carolina represents a high-risk, high-compliance market.

• The concentration of community opposition in North Carolina is pronounced. A 2026 report shows a 45% year-over-year surge in data center rejections or restrictions across the US, with North Carolina counties like Wake, Durham, Orange, and Chatham at the forefront of this resistance through local moratoriums.
• The state’s legislative action distinguishes it from other major data center hubs like Virginia, which have faced grid capacity issues but have not yet advanced statewide mandates on cooling technology. The North Carolina bill could serve as a template for states like Arizona, Texas, and California that face similar or more severe water scarcity challenges.
• The unique political dynamic in North Carolina, where grassroots movements successfully translated local concerns into state-level action, demonstrates a new operational risk for developers. This was highlighted when AI firm Anthropic reportedly spent $1.3 million in a local political race, signaling the high stakes of securing a social and political license to operate.

Closed-Loop Cooling, Vertiv Technology Matures as NC Mandates Adoption

The proposed North Carolina legislation validates closed-loop liquid cooling as a commercially mature and necessary technology, accelerating its transition from a specialized solution for high-performance computing to the default standard for all large-scale AI data centers. The policy effectively ends the debate between lower-Cap Ex evaporative systems and higher-efficiency liquid systems by making water conservation a non-negotiable design parameter.

• Before 2025, open-loop evaporative cooling was a common design choice, prioritized for its lower initial capital cost. The events of 2026 force a paradigm shift where Water Usage Effectiveness (WUE) becomes as critical as Power Usage Effectiveness (PUE), making closed-loop systems with near-zero water consumption a prerequisite for project approval.
• The technological advantages are clear. Advanced liquid cooling systems can achieve a PUE of 1.03–1.15, a significant improvement over the 1.3–1.5 PUE common in air-cooled facilities. This directly translates to lower operational energy costs, helping to offset the higher upfront investment.
• Leading hyperscalers are already aligned with this technological shift. Microsoft actively promotes its use of closed-loop systems that consume “almost zero water, ” and Oracle highlights its use of similar technologies in its AI data centers. This demonstrates that the technology is not only viable but already deployed at scale by sophisticated operators.
• The mandate will spur further innovation and adoption of advanced methods like direct-to-chip cooling and full immersion cooling, which can reduce cooling energy costs by up to 40% and water use by over 90% compared to some traditional systems.

Vertiv & Microsoft, Modeling the Impact of NC Bill SB 730

The most critical event to watch in the next 12 months is the final passage and implementation of North Carolina’s data center regulations. This action will trigger immediate capital allocation shifts toward cooling system retrofits and new-build designs, creating clear winners and losers across the data center value chain.

• If this happens: The North Carolina legislature passes SB 730 or a similar bill, officially mandating closed-loop cooling for large data centers and eliminating key financial incentives.
• Watch this: Data center REITs and private developers with a significant presence in North Carolina will be forced to announce revised Cap Ex plans. Watch for disclosures related to the cost of retrofitting existing facilities with open-loop systems or announcements of new projects being relocated to other states.
• These could be happening: Cooling technology providers like Vertiv and n Vent will likely report increased order backlogs and may announce plans to expand manufacturing capacity to meet the new, regulation-driven demand. Concurrently, legislative committees in other water-stressed states like Arizona and Georgia may begin introducing similar draft bills, signaling the start of a national regulatory trend.
