LONDON : Rio Tinto has entered preliminary discussions with Glencore about a potential megamerger that would reshape the global mining landscape and create the world’s largest mining company by market value. The deal, if consummated, would be driven almost entirely by one thing: copper.
And yeah, this is also happening while BHP is out here quietly tightening the screws. On Jan. 20, BHP says it has increased its FY26 copper production guidance after record throughput at Escondida, the monster Chilean mine that basically sets the tempo for a big chunk of the copper market.

Copper prices are also taking a quick breather after ripping up to around $13,000 a ton earlier this month, which tells you the market is still hot, just not straight-line vertical every single day.

Put it together and the vibe is pretty clear: the majors are leaning hard into large-scale consolidation and “own more copper, now” thinking, because waiting around for new mines to get permitted is a losing strategy.
The Anglo-Australian mining giant has until February 5, 2026, to announce a firm intention to make an offer under UK takeover rules. And while both companies remain tight-lipped about specifics, industry analysts say the strategic logic here is impossible to ignore. The copper supply crunch is coming, and the majors are scrambling to position themselves before the walls close in.
The Copper Deficit Nobody Can Ignore
Let’s talk numbers for a second, because this is where the story really starts to make sense.
Global copper demand is projected to surge 50% to 42 million metric tons by 2040. Meanwhile, production is expected to peak at just 33 million metric tons by 2030. That’s a gap of roughly 9 million metric tons: and that gap isn’t going to close itself.
The drivers are the usual suspects: electrification, the AI data center buildout, renewable energy infrastructure, and rising defense spending across NATO countries. Every electric vehicle needs three to four times more copper than a conventional car. Every wind turbine, every solar installation, every battery storage system: copper, copper, copper.
Rio Tinto knows this. Glencore knows this. And more importantly, their shareholders know this.
The problem for Rio Tinto is that it doesn’t have enough copper growth projects in its pipeline to meet expanding demand. Its existing development options are either too small to move the needle or stuck in regulatory purgatory. The company needs scale, and it needs it now.
Why Glencore? The Collahuasi Factor
Glencore’s copper portfolio is, frankly, the crown jewel Rio Tinto is after.
The Swiss-based trading and mining giant holds a 44% stake in the Collahuasi copper mine in Chile, one of the largest and most productive copper operations on the planet. That single asset alone makes Glencore an attractive target for any major looking to bulk up on copper exposure.
But it’s not just Collahuasi. Glencore operates a diversified portfolio of copper assets across multiple jurisdictions, giving any acquirer immediate geographic diversification and production scale that would take decades to build organically.
A merged Rio Tinto-Glencore entity would control approximately 7% of current global copper mine supply. That’s not market dominance in the traditional sense, but it’s enough to establish the combined company as the world’s largest copper producer with a portfolio of high-quality, long-life assets.
For Rio Tinto, this is about buying time and buying production. The copper price forecast for the next decade suggests prices will remain elevated: potentially significantly so: as supply fails to keep pace with demand. Securing Glencore’s copper assets now, before the supply crunch fully materializes, could prove to be a strategic masterstroke.
Deal Structure: All-Share, But at What Price?
The transaction is widely expected to be structured as an all-share acquisition, which makes sense given the scale involved. We’re talking about a combined market value that would significantly exceed BHP, the current heavyweight champion of the mining world.
But valuation remains a potential sticking point.
Market speculation suggests Glencore shareholders may seek approximately a 30% premium to current trading levels. Rio Tinto, meanwhile, reportedly prefers minimal or no premium: essentially arguing that the strategic benefits of the combination should be enough to bring Glencore investors on board.
That’s a pretty significant gap to bridge, and it could ultimately determine whether this deal happens or falls apart in the final stretch.
The February 5 deadline under UK takeover rules creates a natural forcing function. Rio Tinto either needs to declare a firm intention to bid or walk away. There’s no middle ground here, and the clock is ticking.
Mining M&A Activity Heats Up Across the Sector
This isn’t happening in a vacuum. Mining M&A activity has been accelerating across the sector as companies race to secure critical mineral supplies for the energy transition.
We’ve seen a wave of deals targeting lithium, cobalt, and nickel assets over the past 18 months. But copper has remained somewhat untouched at the mega-deal level: until now. The Rio Tinto-Glencore discussions represent a potential inflection point for consolidation in the copper space.
The rationale is straightforward: building new copper mines is expensive, time-consuming, and increasingly difficult from a permitting standpoint. Buying existing production is faster and, in many cases, cheaper on a per-pound basis than greenfield development.
For context, the average time from discovery to production for a new copper mine now exceeds 15 years in most jurisdictions. That’s too slow to meet the demand surge analysts expect over the next decade. Acquisition is the only realistic path to rapid scale for companies like Rio Tinto.
Regulatory Hurdles and the Coal Question
Any deal of this magnitude will face intense regulatory scrutiny, particularly around concentration of copper concentrate supplies. Antitrust authorities in the EU, US, and China will all have opinions about combining two of the world’s largest copper producers.
But the bigger question mark may be Glencore’s thermal coal assets.
Rio Tinto has spent years positioning itself as a cleaner, more ESG-friendly mining major. It exited coal entirely back in 2018. Glencore, on the other hand, remains one of the world’s largest thermal coal producers, with significant operations in Australia and Colombia.
How Rio Tinto handles the coal question could make or break the deal from a shareholder perspective. Some analysts expect the company would need to commit to divesting Glencore’s coal assets as a condition of closing, potentially to private equity buyers or state-backed entities willing to operate outside ESG scrutiny.
That’s not a simple process, and it adds complexity to an already complicated transaction.
Beyond Copper: Aluminum Synergies
While copper is clearly the main attraction, there’s a secondary strategic logic to the combination that shouldn’t be overlooked.
Rio Tinto operates some of the world’s most advanced aluminum smelting technology. Glencore brings global trading capabilities and processing systems that could complement Rio’s production-focused approach.
A combined entity would have meaningful synergies in aluminum and alumina, creating a more vertically integrated operation that could capture value across the supply chain. It’s not the headline story here, but it’s a nice bonus for shareholders if the deal comes together.
Copper Price Forecast: What This Means for 2026 and Beyond
So what does all this mean for the copper price forecast?
In the near term, the mere fact that two mining giants are discussing a copper-focused megamerger sends a signal to the market: sophisticated players believe copper prices are heading higher, possibly much higher, over the coming years.
The structural supply-demand imbalance isn’t going away. If anything, it’s getting worse as new projects continue to face delays and demand accelerates faster than expected.
Copper has already been trading near record levels in recent months. A successful Rio Tinto-Glencore combination would concentrate even more supply in the hands of a single producer, potentially giving the combined entity significant pricing power in a tight market.
For investors and industry participants tracking the copper space, this is a story worth watching closely. The February 5 deadline will tell us a lot about whether this deal is real or just another M&A flirtation that fizzles out under scrutiny.
Either way, the underlying thesis remains intact: copper is the commodity of the energy transition, and the majors are betting big on it.
