A red-hot start to 2026 pushes global mining beyond $2 trillion

Gold now appears to have US$5,000 in sight, silver’s volatility is intensifying, and copper is regularly hitting all-time highs. Mining equities have responded in kind.

After a blowout start to 2026, the collective market value of the world’s top 50 mining companies now sits comfortably above the US$2 trillion mark reached at the end of last year.

You have to scour the fringes of the mining universe to find assets in decline — and titanium and silicon are hardly pillars of the industry.

While the rally across metals and minerals has been broad-based, with most top-tier miners already posting double-digit percentage gains year-to-date, a handful of underperformers stand out. These laggards — or modest gainers — appear to be influenced by factors beyond buoyant commodity prices.

Global mining is bulking up — and that’s before the mergers and acquisitions currently under discussion.

Since its inception, the MINING.COM Top 50 has been dominated by two firms: BHP and Rio Tinto, the only miners to consistently maintain market capitalisations above US$100 billion, with the occasional wobble.

That distinction now belongs to six companies. The latest addition is Agnico Eagle (TSX:AEM), which on Tuesday joined the ranks of triple-digit billion-dollar miners — albeit narrowly.

The Toronto-based gold producer now sits alongside Chinese heavyweight Zijin Mining (SHA:601899), Southern Copper (NYSE:SCCO) — the mining arm of Grupo México — and Denver-based Newmont Corporation (NYSE:NEM), which rode surging gold and copper prices to the top toward the end of last year.

While the ascent of these stocks is hardly surprising given gold’s stellar run and copper’s relentless climb, the relative underperformance of BHP (ASX:BHP) and Rio Tinto (LSE:RIO) appears tied more closely to uncertainty surrounding mergers and acquisitions.

Although the two remain closely matched, it is notable that Rio Tinto now sits in fourth place, below Southern Copper and Zijin. Rio Tinto is up 2.2% on the London Stock Exchange so far this year, with a market value of US$140.8 billion. By contrast, Zijin has gained 11% in Shanghai in US dollar terms, while Southern Copper has surged 22% in New York in just eight trading days.

In fact, Rio Tinto and BHP — up 4.6% to US$162 billion — are among the few major miners yet to post double-digit gains in 2026. Investor scepticism surrounding a potential tie-up with Glencore appears to be weighing most heavily on Rio Tinto.

Glencore itself has added 15.2% in London, lifting its valuation to US$73.9 billion. Talks between Baar and Melbourne have been ongoing for more than a year, giving investors ample time to assess the implications.

The downsides of a deal for Rio Tinto — coal considerations aside — appear manageable, while the upside, particularly in copper, is significant. A merged entity would emerge as the world’s dominant copper producer, with attributable output of roughly 1.6 million tonnes annually by 2028, potentially exceeding 2 million tonnes in the early 2030s as Glencore’s projects come online. That compares with around 1.3 million tonnes for both BHP and Chile’s Codelco.

Rio Tinto’s recent appointment of three investment banks suggests clarity on the balance of leverage in any potential deal may soon emerge.

BHP’s more muted performance also appears linked to M&A dynamics, with the company increasingly sidelined after multiple failed attempts over the years — including with Rio Tinto — while rivals pursue consolidation.

A combined “RioCore” entity today would be valued at just over US$200 billion — a figure tech giants like Alphabet can add or shed in a single trading session. It is easy to forget that BHP flirted with this level as far back as April 2022, when it briefly overtook Shell as the most valuable stock on the FTSE.

Trading in two other merger candidates has also been underwhelming. Anglo American (LSE:AAL) is up 5.4% year-to-date, valuing the company at US$46.7 billion, while Teck Resources (TSX:TECK.B) has gained 5.2% to reach US$24.3 billion in Toronto — well outside the top 20.

Despite BHP’s late intervention, an Anglo–Teck deal is edging closer to reality, with EU clearance expected within weeks. At current prices, a combined entity would only just crack the top 10. That AngloGold Ashanti (NYSE:AU) is now worth more than its former parent is unlikely to go unnoticed at 17 Charterhouse Square.

Meanwhile, Vale (BOVESPA:VALE3) has largely been absent from M&A discussions, aside from an operational agreement with Glencore in Canada’s Sudbury Basin. Once the third most valuable miner — and briefly worth more than US$100 billion in 2022 — the Brazilian giant continues to slip down the rankings. An IPO of its base metals unit is unlikely before 2027 at the earliest.

Not long ago, mining’s traditional “big five” — BHP, Rio Tinto, Glencore, Vale and Anglo American — routinely occupied the top five spots and accounted for nearly a third of the Top 50’s total value.

Looking beyond recent performance, longer-term charts paint an even starker picture. Over three- and five-year horizons, it is hard to escape the conclusion that the old guard has struggled to keep pace with the new world of mining.

While copper, gold and other commodity specialists have delivered three-, four-, and even eight-fold gains since 2022, the geographically diversified mining model remains underwater.

And mergers, acquisitions, spinoffs and bolt-ons, it seems, have yet to provide a durable remedy for this persistent underperformance.
