Nov 5 (Reuters) - The Nasdaq slid more than 10% from its ​record close on Thursday, on track to confirm a correction as ‌worries over massive AI spending and heightened scrutiny of data-center expansion rattled tech stocks.

Thursday's slide erased the previous session's ​gains after Democrats swept both houses of Congress, as investors ⁠weighed the prospect of greater scrutiny of further AI infrastructure buildout.

"When you go ​from full unified control under one party to full unified control under another ​party that can also represent quite a bit of uncertainty, discontinuity and abrupt change to policy," said Sameer Samana, senior global market strategist at Wells Fargo Investment Institute.

"When it looked like ​the Democrats were going to take significant majorities in both the House ​and the Senate, we thought that at the very least, it would lead to markets taking ‌a ⁠little bit of a pause."

A decline of 10% from the most recent record closing high is widely considered a correction. It would mark the Nasdaq's second correction this year.

Sentiment toward AI-linked stocks has deteriorated in recent weeks, with the ​Nasdaq shedding more than $2.5 ​trillion in market ⁠value in October. Several big tech companies are tapping debt markets to help finance billions of dollars in planned investments in ​data centers, chips and other infrastructure required to support AI ​development.

Investors have ⁠increasingly questioned how quickly those investments will translate into profits, particularly as persistent geopolitical tensions in the Middle East and fears of prolonged inflation have kept borrowing ⁠costs elevated.
