President Donald Trump Just Called Nov. 5 One of the Stock Market's "Worst Days in History" Due to Election Results -- but Warning Signs Have Been Apparent for Months
Key PointsA gubernatorial blue wave has put the artificial intelligence (AI) data center build-out on notice.
On November 5, 2026, Wall Street experienced one of its worst days in history, with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all plummeting by significant margins. President Donald Trump blamed the election results for the market's poor performance, but this overlooks several warning signs that have been present for months.
The most alarming concern is the shift in power at the gubernatorial level, with Democrats flipping five Republican governorships in states crucial for AI data center expansion. Texas, Georgia, and Ohio are especially impacted, as Democratic candidates like Gina Hinojosa have pledged to restrict data center approvals until state legislatures pass relevant laws.
This state-level regulation could hinder AI growth in these critical regions. Additionally, the stock market entered 2026 at its second-highest valuation in 156 years, with the S&P 500's Shiller Price-to-Earnings (P/E) Ratio peaking at 42.84, far above its long-term average of 17.45. This premium valuation has been unsustainable, as history shows that such high valuations precede significant market declines, including the 20% to 89% drops in the Dow, S&P 500, and Nasdaq Composite.
The bond market also warned about the AI infrastructure build-out, with several companies issuing debt at higher yields due to concerns over the underlying risks. Thus, the market's decline on November 5 was the result of a confluence of factors, including election outcomes, state-level regulatory changes, overvaluation, and bond market risks.
