CME futures halted due to data center cooling failure: AI-era infrastructure stress indicator?

On November 28,2025, CME Group halted futures trading across major markets (WTI crude, S&P futures, US 10-Year Treasury contracts) due to a cooling system failure at CyrusOne’s Aurora, Illinois data center [1,3]. The outage lasted over 10 hours, disrupting trillions in derivative trading [1]. Reddit users debated whether this incident was a one-off technical issue or a sign of AI-era infrastructure stress, noting AI workloads increase heat and power usage [8].

AI workloads now drive 75% of new data center projects, with AI-optimized facilities projected to represent 28% of the global market by 2027 [4]. Traditional cooling systems are insufficient for AI’s intense heat output;53% of industry respondents expect liquid cooling to dominate future high-density projects [4]. The global data center infrastructure market is on track to surpass $1 trillion by2030, driven by AI demand [5].

Competitive dynamics are shifting: CyrusOne (CONE) faces downward pressure with an analyst consensus price target of $85 (-5.9% from current) [0]. Post-outage, the company added cooling redundancy, increasing operational costs [1]. Comfort Systems USA (FIX) is well-positioned to capture AI-driven cooling demand, with a Hold consensus rating and4 Buy recommendations [0]. Innovators like ABB are launching AI-ready power solutions to support gigawatt-scale AI data centers [5].

1. AI-Infrastructure Link
   : AI workloads are exacerbating data center cooling and power demands, leading to increased infrastructure stress and outages.
2. Cooling Transformation
   : Liquid cooling adoption is accelerating as a solution to AI’s heat output, replacing traditional HVAC systems [4].
3. Redundancy-Latency Trade-off
   : Data center operators must balance redundancy (to avoid outages) with latency requirements for high-frequency trading clients [8].
4. Sustainability Gap
   :45% of IT leaders admit their current infrastructure fails to meet energy and carbon reduction goals [6].

• Risks
  : Legacy data center operators (e.g., CONE) with outdated cooling systems face operational risks and margin pressure from required upgrades [0,1]. Global grid infrastructure is strained by AI data centers’ gigawatt-scale power needs [7].
• Opportunities
  : HVAC providers (e.g., FIX) and liquid cooling specialists stand to benefit from AI-driven demand for advanced cooling solutions [0,4]. Companies offering AI-ready power systems (like ABB) can capture market share in the growing data center infrastructure market [5].

The CME outage highlights critical vulnerabilities in data center infrastructure amid surging AI demand. AI workloads are driving a shift toward liquid cooling and gigawatt-scale power solutions. Stakeholders should note:

• Data center operators need to re-evaluate redundancy strategies while considering latency needs.
• HVAC and liquid cooling providers have growth opportunities in AI-optimized data centers.
• Traders face operational risk from infrastructure failures in critical financial markets.
• Regulators may increase scrutiny on data center resilience and sustainability [1,6].
