Goldman Sachs has suspended the bond issuance for a digital center company related to the CME Group incident.

Goldman Sachs has suspended a planned $1.3 billion five-year CMBS issuance for data-center operator CyrusOne—its largest potential CMBS deal—after a cooling-system failure at a CyrusOne campus triggered a >10-hour outage at CME Group; the largest AAA tranche was slated to be $606.9m priced about 190bp over SOFR and pricing has been postponed with a restart possible in Q1. The three-campus collateral in the Chicago suburbs houses CME, which accounts for roughly 14% of contracted rent and is the site’s second-largest tenant; CyrusOne says it has bolstered backup cooling after site temperatures reportedly exceeded 100°F, though the root cause remains unclear. The incident is being treated as a wake-up call for investors in the AI data-center boom, highlighting tenant-concentration and operational-resilience risks, the potential for lease-termination triggers after repeated outages, and the likelihood of tighter credit scrutiny or repricing on similar financings.

Analysis

Goldman Sachs has suspended a planned $1.3 billion five-year CMBS for data-center operator CyrusOne after a cooling-system failure at a CyrusOne Aurora campus triggered a >10-hour outage at CME Group; the largest tranche was a $606.9 million AAA bond marketed at about 1.9 percentage points above SOFR and preliminary market feedback had been targeted for Nov. 25 before the pause. The deal is collateralized by three Chicago-suburb campuses roughly 35 miles from downtown Chicago and may restart in Q1, with CyrusOne jointly owned by KKR & Co. and Global Infrastructure Partners.

The outage raised specific counterparty and concentration risks: CME accounts for about 14% of contracted rent at the affected campus and is the second-largest tenant, and site temperatures reportedly exceeded 100°F. CyrusOne says it has bolstered backup cooling but the root cause remains unclear and CME did not switch to its New York backup because outage was initially judged brief.

Market implications include increased investor scrutiny of data-center lease termination clauses and operational resiliency, likely leading to wider spreads or additional credit enhancements on similar CMBS financings and near-term repricing risk for issuers tied to exchange-dependent tenants.

Key Decisions for Investors

• Defer participation in the suspended CyrusOne CMBS until issuer provides a root-cause analysis and independent verification of remediation,
• For existing CyrusOne or related CMBS holders, review lease concentration (CME ~14% of rent) and termination-trigger provisions and consider trimming exposure or hedging pending clarity,
• Require wider spreads, stronger credit enhancements or explicit operational-resilience covenants on new data-center CMBS given demonstrated outage risk,
• Monitor repricing and market feedback when the transaction potentially reopens in Q1 and use that window to reassess sector allocation and counterparty risk
