Rio Tinto Group and Glencore Plc have confirmed preliminary discussions regarding a possible combination of some or all of their businesses, which could involve an all-share acquisition of Glencore by Rio Tinto. This development, announced on 9 January 2026, comes just over a year after earlier negotiations broke down due to disagreements on valuation. The talks, expected to proceed through a court-sanctioned scheme of arrangement, position the combined entity to become the world’s largest mining company, with a market capitalisation approaching $207 billion, surpassing BHP Group’s current standing, according to Reuters.
Market reactions were immediate and divergent, reflecting investor uncertainty amid limited details on the deal’s structure. Glencore’s American depositary receipts surged by around 8.8% in New York trading, while Rio Tinto shares dropped as much as 6.6% in Sydney. This volatility underscores the sector’s heightened sensitivity to consolidation moves, particularly as major producers seek to strengthen positions in copper, a metal essential for the global energy transition. Under UK takeover rules, Rio Tinto has until 5 February 2026 to announce a firm intention to proceed or walk away for six months.

The renewed interest aligns with a broader wave of mergers and acquisitions in the mining industry, driven by the imperative to secure supplies of critical minerals. Recent activity includes Anglo American’s agreement to acquire Teck Resources, which expands copper exposure following its defence against a prior BHP approach. Such deals highlight how companies are prioritising scale and efficiency to address anticipated supply constraints, with copper emerging as the focal point amid surging demand from electrification, renewable energy projects, and data centre infrastructure.
Copper prices have reached unprecedented levels in early 2026, climbing above $13,000 per metric ton on the London Metal Exchange, fuelled by mine outages, stockpiling ahead of potential US tariffs, and expectations of tighter future availability. This rally supports the strategic logic of a Rio-Glencore tie-up, which would significantly bolster Rio’s copper production through assets like Glencore’s stake in the Collahuasi mine in Chile—one of the world’s richest deposits—and enhance overall output in a market where demand is projected to rise 50% to 42 million metric tons annually by 2040, according to S&P Global. Traditional economic growth, electric vehicles, grid expansions, artificial intelligence-driven data centres, and defence modernisation are all contributing to this acceleration, potentially creating a shortfall of up to 10 million metric tons without substantial new investment and recycling improvements.
For Rio Tinto, under the leadership of Chief Executive Simon Trott, the discussions represent a test of its disciplined approach to growth, following a focus on cost reduction and asset sales to streamline operations around iron ore and copper. Glencore’s copper growth plans, aiming to nearly double production over the next decade, make it an attractive partner, though analysts note challenges in reconciling differing corporate cultures and asset portfolios.
A key hurdle remains Glencore’s substantial coal business, the world’s largest thermal coal exporter, which contrasts sharply with Rio Tinto’s complete exit from coal operations in recent years. Investors and observers suggest that any merged entity might need to divest coal assets to align with shareholder preferences and environmental considerations, potentially unlocking value but adding complexity to negotiations.
The outcome of these talks could reshape the competitive landscape in mining, intensifying the race for copper dominance at a time when supply risks loom large. While no firm offer has been made, the exploratory nature of the discussions signals ongoing strategic realignment in an industry grappling with geopolitical pressures, technological shifts, and the urgent need to meet escalating global demand for transition metals.
