Rio Tinto in Early Talks to Acquire Glencore in All-Share Deal

Rio Tinto in Early Talks to Acquire Glencore in All-Share Deal
Published on: Jan 8, 2026

The global mining industry could be poised for a blockbuster consolidation. Swiss mining and trading giant Glencore (GLNCY) confirmed on Thursday that it is engaged in preliminary discussions with the world’s largest iron ore producer, Rio Tinto (RIO), regarding a potential merger.

A successful deal would create the world’s largest mining company by market value, with a combined enterprise value estimated to exceed $260 billion.

The Proposal: An All-Share Merger

According to statements from both companies, the talks concern a “potential combination of some or all of their businesses.” One option under consideration is an all-share acquisition of Glencore by Rio Tinto. The transaction framework is expected to be implemented via a court-sanctioned “scheme of arrangement.” Both parties emphasized that discussions are at a preliminary stage and that “there is no certainty that any transaction will occur.”

Based on the latest closing prices, Rio Tinto boasts a market capitalization of approximately $142 billion, while Glencore is valued at around $65 billion. A straightforward combination would yield a merged entity with a market cap nearing $207 billion. When debt is included, the enterprise value of the combined group would surpass the $260 billion mark, according to LSEG data and a report by the Financial Times, which first broke the news.

Following the confirmation, Glencore’s U.S.-listed shares rallied 6%, whereas Rio Tinto’s U.S. shares dipped 0.6%. Under U.K. takeover regulations, Rio Tinto faces a deadline of February 5 to either make a formal offer or walk away.

Second-Round Talks with a Focus on Copper

This marks the second round of talks between the two mining giants in just over a year. Glencore had initially approached Rio Tinto in 2024, but those discussions were short-lived. Since then, Rio Tinto has undergone significant changes. Under its new CEO, Simon Trott, who took the helm in August, the company has been focused on streamlining operations and sharpening its focus on core assets.

The revival of talks highlights a strategic alignment between the two firms, particularly in copper. As the world accelerates its transition to greener energy, demand for copper—a critical metal for electrification—is expected to surge. A merger between Rio Tinto, the world’s second-largest miner, and Glencore, a major player in coal and base metals, would create a formidable force in the copper market.

If finalized, this potential mega-merger would not only reshape the global mining landscape but could also have profound implications for commodity supply chains and the market for minerals vital to the energy transition.
