Microsoft slips as data-center policy fears spread through AI infrastructure stocks

Microsoft shares opened lower on Friday, November 6, in a sector-wide pullback. Investors are weighing whether the Democratic sweep of Congress in the midterms will slow U.S. data-center construction, which would affect the pace of hyperscaler AI spending. Benzinga reported that AI and data-center-linked stocks sold off on Thursday, and UBS estimated that around 30% of expected U.S. data-center capacity additions in 2028 could be at risk from possible construction pauses. Benzinga's premarket quote showed Microsoft down about 0.7% near $532, and the same coverage described the move as broad-based rather than driven by company-specific news. This follows the stock's record close earlier in the week, so the near-term move is largely a policy-sentiment story.

1. Microsoft shares fell about 0.66% to $532.39 in premarket trading on Friday, according to Benzinga.
2. Benzinga reported that AI and data-center-linked stocks tumbled on Thursday after the midterm results.
3. UBS analysts estimated around 30% of expected U.S. data-center capacity additions in 2028 could be at risk from construction pauses, as reported by Reuters via Benzinga.
4. Benzinga's Thursday trading note said Microsoft's volume was close to normal and the stock appeared caught up in broad tech selling rather than company news.
5. Microsoft's shares had set an intraday all-time high of $558.05 on Wednesday, November 4, per Benzinga.
