Stock futures were halted by CME Group early Friday due to a data-center cooling issue.

But there were still plenty of stocks making moves ahead of the open:

Alphabet rose more than 1% in premarket trading as the tech giant looked set to restart its rally after a blip on Wednesday. Investors have become more excited about Google's AI efforts, and its chances of challenging Nvidia's dominance, following the launch of the Gemini 3 chatbot and a potential deal for Meta to use its chips. Nvidia stock edged 0.2% higher.

Stocks exposed to cryptocurrencies were boosted ahead of the open after Bitcoin climbed above $90,000 and kept rising toward $92,000 over the Thanksgiving holiday. Coinbase Global was up 2.7%, Robinhood Markets rose 1% and Strategy -- the largest corporate holder of Bitcoin -- pointed 2.2% higher.

GameStop jumped 3.9% in premarket trading as the meme stock continued to gained momentum ahead of its earnings, which are expected on Tuesday. Heading into Friday's trading, the shares are up 7.4% this week.

Circle Internet Group rose 3.6% after S&P Global cut its rating of rival stablecoin issuer Tether to "weak" on Wednesday. The ratings agency noted that corporate bonds, precious metals, Bitcoin, secured loans, and other riskier investments made up 24% of Tether's reserves as of Sept. 30, up from 17% a year ago.

Retail stocks were also in focus on Black Friday, with Amazon, Walmart, and Costco Wholesale stocks all rising in premarket trading.
