Pre-Market Brief: CME Outage Disrupts Futures Trading, Key Earnings & Economic Data Awaited (Nov 28, 2025)

Pre-market activity on November 28,2025 is significantly disrupted by a CME Group outage triggered by a cooling system failure at its CyrusOne data center, halting all futures/options trading (oil, gold, FX, Treasurys, US equity futures) [2]. This outage follows Wednesday’s broad market gains: S&P500 (+0.7% to 6812.61), Dow Jones (+0.7% to47427.12), Nasdaq (+0.8% to23214.69) [3]. Tech (XLK +1.3%) and materials (XLB +1.2%) sectors led Wednesday’s gains [3]. Key catalysts for today include earnings reports (CHA, LEDS before bell; GLBS after) [1] and economic data releases (Chicago PMI, Fed balance sheet) [3]. Germany’s November inflation remained stable at2.3% [5], which may ease global rate hike concerns.

1. Infrastructure vulnerability: The CME outage highlights critical dependencies on data center cooling systems for financial market operations [2].
2. Sector momentum: Wednesday’s tech and materials leadership could persist once trading resumes, given their strong performance [3].
