Trading disruption struck the Chicago Mercantile Exchange this morning when a data center cooling system failure knocked out futures trading services, forcing emergency protocols as markets processed Black Friday retail data and intensifying tech rivalries across AI and consumer hardware sectors.
CME Group scrambled to restore trading services this morning after what the exchange called a data center "cooling issue" took down futures and options markets during pre-market hours. Individual stocks continued trading normally, but the disruption highlighted the fragility of market infrastructure during one of the year's busiest trading periods.
The technical failure comes as markets digest mixed signals from the holiday shopping season. Black Friday's evolution from a brick-and-mortar stampede to a digitally-driven event reflects broader shifts reshaping retail. Deloitte data shows average consumer spending dropping 4% to $622 for the holiday weekend, while online sales continue outpacing physical store traffic for the sixth consecutive year.
Meanwhile, Alphabet emerged as November's standout performer, with shares surging over 13% as Wall Street embraces the company's AI resurgence. The Google parent's momentum started with its Ironwood tensor processing unit announcement and accelerated following last week's Gemini 3 model launch, which drew praise from Silicon Valley insiders.
"We've been preparing for this AI cycle longer than most realize," one Alphabet insider told analysts during recent earnings calls. The company's 70% year-to-date stock gains now make it the top megacap tech performer, though experts warn that AI leadership remains fluid and competitive.
The AI race isn't the only tech battle heating up. Alibaba launched its Quark AI smart glasses yesterday, directly challenging Meta's Ray-Ban collaboration that debuted in September. The Chinese giant's entry into wearables signals broader ambitions beyond e-commerce, as tech companies scramble for position in the next computing platform.
Smartphone dynamics are shifting too. Apple is set to ship more devices than Samsung this year for the first time since 2010, according to Counterpoint Research. Strong iPhone 17 demand is driving the reversal, suggesting Apple's premium positioning continues resonating despite economic headwinds.
Retail trends reveal another surprising winner: Korean beauty products. The K-beauty phenomenon is exploding across American stores, with NielsenIQ tracking 37% growth to over $2 billion in annual sales. Major retailers from to are expanding Korean brand selections, while Seoul's Olive Young plans its first U.S. store in Los Angeles next year.
