Oracle denied on Friday a media report that it was delaying OpenAI-related data centers, following investor worries over its debt-fueled AI infrastructure buildout.

The hit to Oracle and Broadcom weighed on other tech shares during the day, as investors worried about AI spending and the lack of a clear timeline on returns from the investments. The tech-heavy Nasdaq sank 1.4%, while the S&P 500 Index fell 0.9% on Friday afternoon, a day after finishing at a record high.
