Wall Street’s enthusiasm for artificial intelligence took a major hit after Democratic gains in the midterm elections unsettled investors. The sell-off erased about $2.5 trillion from the Nasdaq 100, underscoring how much of the market’s recent optimism has been built around the AI boom.
The reaction was not just about politics. Investors are now worrying that stronger Democratic influence could slow the build-out of data centres and bring more scrutiny to the infrastructure that supports AI growth.
Why the AI trade sold off
The AI trade has been one of the strongest themes in markets, with investors betting that spending on chips, cloud services and data centres will keep rising. That confidence helped lift technology shares and pushed valuations higher.
After the election results, that optimism weakened. Traders appeared to reassess whether the policy environment could become less favourable for rapid expansion in AI-related infrastructure.
Why data centres are in focus
Data centres are central to the AI build-out because they provide the computing power and storage needed for AI systems. When investors worry about delays, approvals or tighter oversight, they often price that risk into related stocks quickly.
The concern in this case is that Democratic gains could bring more scrutiny to new projects. Even without any immediate policy change, markets often react early when they see the possibility of slower growth ahead.
