The copper market finds itself caught in a tug-of-war between narrative and reality. The artificial intelligence infrastructure boom has pushed copper to near-record highs, yet doubts about supply-demand fundamentals are mounting, with some market participants beginning to question whether current prices reflect genuine demand or an artificially inflated level created by a combination of a technology bubble and policy distortions.

Last week, thousands of metals investors and mining executives gathered in London for the annual London Metal Exchange industry gathering. The dominant topic was singular: copper, and whether the AI revolution will continue to drive the red metal to record highs. At the same time, however, another question quietly circulated — if the AI boom cools, can the anticipated surge in copper demand over the next decade still materialize? "The probability that AI is a bubble exceeds fifty percent," one top metals investor said bluntly, acknowledging that a fading AI growth narrative "would deal a blow to metal prices."

Meanwhile, Macquarie analyst Alice Fox noted at an LME Week briefing that copper prices have exceeded the range that supply levels can justify: "A large global surplus emerged last year, and we expect surpluses to persist for several years to come." Potential US copper tariff policies creating artificial market distortions are also seen as a significant factor propping up prices, and once the tariff threat is removed, the market could face rapid destocking pressure.

The AI Demand Narrative: From Zero to Protagonist

Copper, widely used in cables, wiring, automobiles, consumer electronics, and large-scale construction projects due to its high conductivity, is a core raw material of the electrification era. The rise of the AI data center construction wave has caused its demand outlook to expand dramatically.

Graeme Train, head of metals and minerals analysis at commodities trading giant Trafigura, said: "Data centers were the core story of the past year. In 2023, their contribution to copper demand growth was almost zero, and we estimate they will add about 350,000 tonnes this year." Total global copper demand is approximately 28 million tonnes annually, the vast majority of which is supplied by mines.

It is precisely the expectation of copper supply shortages that drove prices to near-record highs of close to $15,000 per tonne earlier this year, and they have continued to hover at elevated levels recently. However, Train also noted that high copper prices have "compressed demand from non-AI sectors," making it "difficult for overall consumption to grow." This contradiction — an AI-driven demand narrative versus weak actual total demand growth — constitutes the most fundamental tension in the current copper market.

Mining Capital Converging on Copper

The global scramble for copper resources has driven several major mining M&A negotiations over the past two years, but only one has truly materialized — the planned large-scale merger between Anglo American and Canada's Teck Resources.

Major miners continue to expand their copper exposure, with boards and investors alike pushing for increased copper mine output, gradually shifting strategic focus from diversified multi-metal growth toward dedicated copper positioning. Capital markets have responded positively — shares of miners with high copper exposure, such as BHP and Freeport-McMoRan, have risen between a quarter and a third cumulatively this year.

In August, the world's largest mining company, BHP, announced that copper revenue had surpassed iron ore for the first time to become its largest profit source. Chief Financial Officer Vandita Pant nonetheless stated earlier this month at a mining summit that the company still places great importance on its iron ore, coking coal, and fertilizer businesses.

Copper's rise as a strategic asset for technology and defense has also fostered increasingly close new relationships between the metals industry and governments. Several executives noted that given the lengthy timelines required to bring new mines online, copper — rather than chips or capital — may be the true bottleneck constraining the pace of AI development.

Tariff Distortions and Artificial Tightness

Beyond AI expectations, uncertainty surrounding US tariff policy is also artificially inflating copper prices and distorting global inventory distribution.

According to reports, in the final week of October, 90% of copper inventories held across the global warehouse networks of the London Metal Exchange and the New York Mercantile Exchange were concentrated within the United States, compared with only about 20% two years earlier. This abnormal concentration is the result of arbitrage positioning by the market in anticipation of potential US copper tariffs.

Macquarie warned that once the tariff threat is lifted, "a rapid clearance-style selloff could occur as physical inventories seek new destinations." This means that part of the current support for copper prices is "artificially elevated" by policy expectations and does not reflect genuine global supply-demand conditions.

Market Divergence: Bubble or Long-Term Support

At the LME Week gathering, both bullish and bearish voices coexisted, with notable divergence.

One top investor said copper prices could be expected to fall by as much as $1,000 per tonne from their highs earlier this year. Another noted that the metals market's boom largely "depends on AI," with rising interest rates, elevated inflation, and swelling US government debt constituting major downside risks. A third said the industry is mired in a "vicious cycle of groupthink," but contrarian views that copper prices will "pull back sharply" have begun to emerge.

Additionally, Macquarie noted in a research report that while increased technology investment will boost overall copper demand, "downside risks surrounding the scale of AI data center construction and the infrastructure required are rising."

Long-Term Bulls Remain the Mainstream Consensus

Despite considerable short-term doubts, mining executives remain broadly optimistic about the long-term outlook.

Freeport-McMoRan CEO Kathleen Quirk told the Financial Times: "I don't think it will be linear... we will encounter challenges, but the long-term trend for copper demand is positive."

Anglo American CEO Duncan Wanblad said last week at a Financial Times-affiliated conference that "sustainable support for copper prices at current levels is likely to continue until the supply-demand gap is bridged."

Loic Jonchery, a senior metals trader at metals trading firm Centalion, summed up the market's core dilemma in one sentence: "The current price is expensive for today's market. The question is whether it is expensive enough to solve tomorrow's supply problem — that is a much harder question to answer."
