Prediction: Nov. 3 Will Be a Huge Day for the Stock Market
Tomorrow's midterms could matter more for investors than usual, since so much of the stock market now rides on AI, and I think the bond market's reaction will tell you more than the stock market's.
On Tuesday, November 3, 2026, the outcome of the midterm elections could significantly influence the course of Washington for the next two years. Voters will determine whether Republicans maintain control of Congress or if Democrats secure enough seats to rein in President Donald Trump's policies. Although elections typically carry substantial consequences for the stock market, this particular event could have an especially substantial impact due to the close ties between the S&P 500 and artificial intelligence (AI) technology.
A striking 49% of the S&P 500 (^GSPC -0.21%) is linked to AI, an industry whose trajectory could be drastically altered by potential policy changes.
Investors should keep an eye on several key factors. Despite common misconceptions, midterms are generally favorable for the stock market. Historically, the S&P 500 has seen an average annual gain of 15.1% in the year following a midterm election, excluding dividends, since 1950. The reason behind this positive trend lies in the political uncertainty that often results from divided governments, making it challenging for either party to implement significant changes.
Moreover, gridlock is typically favored by market participants, as it helps maintain stability and reduces uncertainty, particularly during periods of heightened sensitivity among bond investors regarding federal debt.
The AI sector, which demands substantial capital investment for building and maintaining data centers, is highly dependent on borrowing costs. Companies like Meta (META -0.73%) and Amazon (AMZN +3.21%) are increasingly resorting to borrowing to fund their AI initiatives. Consequently, any fluctuations in bond yields could directly impact the industry's financial landscape.
While larger players may reduce their spending if borrowing costs rise, smaller, heavily indebted firms might face difficulties in securing the necessary financing for survival.
However, there are potential positive outcomes as well. Democrats have generally opposed data center construction and supported moratoriums, although this stance is becoming more rare as a shared interest between both parties. A Democratic victory could lead to increased regulatory scrutiny and challenges for the AI industry. Nevertheless, predicting the exact market reaction to tomorrow's election results is impossible.
Still, it is reasonable to expect that the outcome will have major implications for investors. Instead of focusing on whether the S&P 500 rises or falls, it would be prudent to closely monitor how Treasury yields respond, as they are likely to provide more insight into market sentiment.
