Copper Prices Fall as Traders Reassess AI Data-Center Demand

Copper prices fell this week amid fears that a Democratic sweep in the U.S. midterm elections could slow the artificial-intelligence data center buildout that has powered the metal's rally this year, according to the Financial Times.

The decline marks a sharp reversal for a metal that had climbed through 2026 on forecasts of surging demand tied to the buildout of AI infrastructure, the newspaper reported. Traders are now weighing whether that demand story holds up under a changed political landscape in Washington.

Why Did Copper Prices Fall This Week?

The sell-off tracked directly with the outcome of the midterm elections, the Financial Times reported, as traders recalibrated expectations for the policy environment facing AI infrastructure projects. The newspaper described the reaction as rooted in fears of a political backlash against the AI data center expansion that commodity markets had priced into copper's 2026 gains.

Copper's run-up this year was built on a bet that AI data centers would need far more of the metal than prior demand models assumed — a bet now facing new political uncertainty.

What Has Been Driving Copper's 2026 Rally?

Copper had soared this year on forecasts of surging demand from AI data centers, the Financial Times reported, as the metal became a proxy trade for the broader AI infrastructure build. That link between a single sector's growth and a global commodity's price is not unusual in metals markets, where industrial buyers often represent a concentrated share of incremental demand, but it also means the trade is sensitive to any sign that the underlying growth story is slowing.

Why Would a Democratic Sweep Change the AI Calculus?

The Financial Times did not detail specific policy mechanisms, but framed the market's reaction around the risk that a Democratic sweep in the midterms could translate into a political backlash against the pace of AI data center construction. Large infrastructure buildouts typically require permits, financing commitments, and regulatory certainty that can take years to secure, which is why commodity traders often move quickly to reprice risk the moment the political backdrop for those projects shifts, even before any specific legislation or regulation is proposed.

What Happens Next for Copper Markets?

The Financial Times framed the move as a market reassessment rather than a verdict on AI demand itself, noting the risk is now attached to the pace and durability of the data center buildout. Whether the decline proves lasting will likely depend on how quickly the new political alignment in Washington signals its stance toward AI infrastructure projects already underway, and whether the companies building that infrastructure adjust their own spending plans in response. For now, the Financial Times reported, the metal that had become a stand-in for the AI boom is trading on doubts about that boom's next phase.
