08:33 AM EST, 11/28/2025 (MT Newswires) -- US equity futures were little changed pre-bell Friday as the Chicago Mercantile Exchange gradually resumed operations following an outage that disrupted futures trading of various asset classes, including equities.

Exchange operator CME Group ( CME ) said early Friday it halted trading across its markets due to a cooling issue at its CyrusOne data centers.

US operations were gradually being restored as of 8 am ET and full operations are expected for stock futures before market open, according to reports.

Dow Jones Industrial Average futures were flat, S&P 500 futures were up 0.1%, and Nasdaq futures were 0.2% higher following the outage.

US stock markets will close early at 1 pm ET Friday.

Oil prices were mixed, with front-month global benchmark North Sea Brent crude down 0.5% at $62.57 per barrel and US West Texas Intermediate crude up 0.6% at $59.00 per barrel.

The Chicago Purchasing Managers' Index is scheduled for release at 9:45 am ET.
