Copper Miners ETF Poised for Boost as Key Mine Nears Restart

Copper miners ETF COPX navigates AI-driven demand surge and a major supply catalyst as Freeport-McMoRan's Grasberg mine nears full restart in 2026.

Investors in the Global X Copper Miners ETF (COPX) are monitoring two powerful, concurrent trends. While the structural demand from artificial intelligence infrastructure provides a long-term tailwind, a near-term operational catalyst is emerging in Indonesia: the impending return to full capacity of the massive Grasberg mine, a development set to significantly bolster one of the fund's core holdings.

AI Demand and a Tightening Market

The long-term investment case for copper is being fundamentally reshaped by the rapid expansion of AI. Market analysts, including those at J.P. Morgan, highlight that AI data centers require substantially more copper for power distribution and cooling than traditional facilities. This sector alone is projected to consume approximately 475,000 tonnes of the metal in the current year.

This demand surge is unfolding against a constrained global market. According to experts from ING and J.P. Morgan, the refined copper market is forecast to face a supply deficit ranging between 330,000 and 600,000 tonnes in 2026. The situation is exacerbated by market distortions, notably sector-specific U.S. tariffs, which analysts say have created an artificial bifurcation—leading to material accumulation in U.S. warehouses while a shortage persists across the rest of the world.

Freeport-McMoRan Approaches a Critical Turnaround

A pivotal factor for the ETF is the progress at Freeport-McMoRan, a top holding with a weighting exceeding 5.4%. The company is targeting the second quarter of 2026 to restart major production blocks at its Grasberg operation, the world's second-largest copper mine. Output was severely curtailed following a major landslide in September 2025. Freeport-McMoRan anticipates restoring about 85% of the mine's original capacity by the second half of the year. A smooth return to normalized operations is expected to have a direct and positive impact on the miner's financial performance and valuation.

Beyond Freeport's operational challenges, the fund's third-largest position, Glencore, recently made headlines for different reasons. Its planned mega-merger with Rio Tinto collapsed due to disputes over future management roles. Regulatory provisions now prevent new discussions about creating the world's largest copper producer until August 2026 at the earliest.

ETF Flows Reflect Shifting Sentiment

The compelling structural narrative for copper fueled massive investor interest in the COPX ETF throughout 2026, resulting in net inflows of roughly $1.7 billion. These inflows expanded the fund's assets under management to approximately $7.5 billion. This followed an exceptionally strong performance period that saw the ETF gain over 117% on a twelve-month view.

Recently, however, this momentum has moderated. On a one-month basis, the fund experienced a pullback of nearly 13%, which coincided with short-term outflows totaling around $734 million.

The future trajectory of this broadly diversified ETF now hinges significantly on operational execution at its key holdings. Should Freeport-McMoRan successfully reactivate its Grasberg facilities this quarter, it would help stabilize supply in a deficit-prone global market and solidify the earnings power of one of the fund's most important investments.
