S&P 500 Swings $2.9 Trillion After US Midterm Election Rally and AI Spending Fears
The S&P 500 experienced a sharp three-session reversal after US midterm election results triggered an initial market rally, followed by concerns over artificial intelligence spending and a rapid recovery in buying activity, according to Coin Bureau.
On November 4, Democrats swept the US midterm elections, and the S&P 500 added $1.2 trillion in market capitalization. However, the positive reaction lasted less than 24 hours before investors began reassessing the potential implications of the election results for corporate and technology spending.
AI Spending Concerns Trigger $2.9 Trillion Decline
On November 5, concerns emerged that the new Congress could slow spending on artificial intelligence. The uncertainty weighed on stocks, sending the market sharply lower. By 3:30 p.m. ET, the S&P 500 had reached its lowest point of the session, wiping out a record $2.9 trillion in market capitalization in a single day.
The scale of the decline marked a dramatic reversal from the previous day's $1.2 trillion increase. The concerns highlighted in Coin Bureau's account centered on the possibility that changes in Congress could affect the pace of AI-related spending.
Buyers Return as S&P 500 Adds $1.5 Trillion
The market direction changed again on Monday, when buyers returned and stocks opened sharply higher. The S&P 500 added $1 trillion in markets capitalization within hours of the opening bell.
Buying activity continued throughout the session. By the 4 p.m. ET close, the index had gained another substantial amount, bringing its total market capitalization increase for the day to $1.5 trillion. Coin Bureau described the performance as the S&P 500's best day since April.
The sequence of events included a $1.2 trillion increase on November 4, a record $2.9 trillion loss on November 5, and a $1.5 trillion recovery on Monday. The figures illustrate the sharp changes in market capitalization across the three sessions, as election-related optimism gave way to concerns about AI spending before buyers returned.
