**Deck**: Major producers in the Democratic Republic of Congo increased copper output sharply in early 2026 while cobalt production dropped, according to new figures from Glencore. The split trend matters for electric‑vehicle makers and energy firms that rely on both metals to power the green transition.

The Democratic Republic of Congo’s mining sector is sending a mixed signal to global manufacturers: copper is flowing faster, but cobalt is tightening. New output figures from Glencore, one of the country’s biggest operators, show a strong year‑on‑year jump in copper production alongside a steep fall in cobalt volumes for the first half of 2026.

Glencore reported producing 397,000 tonnes of copper globally in the period, up 15% from a year earlier. Of that, 138,400 tonnes came from its African assets, a 66% increase that underscores how central the DRC has become to meeting rising demand for the red metal. Copper is a backbone material for power grids, electric motors, and renewable‑energy infrastructure, and the world’s push toward electrification has made reliable supply a strategic priority.

Cobalt told a different story. Glencore’s total cobalt output fell 46% to 10,200 tonnes over the same period. While the company did not break down all the reasons in these topline figures, the decline feeds into a broader concern in the electric‑vehicle and battery industries: that the most geographically concentrated materials in their supply chains may also be the most volatile.

For Congolese mining communities and workers, these shifts determine what projects expand, where investment flows, and which jobs feel secure. Copper‑heavy operations may see more capital and infrastructure spending, from new processing lines to local roads and power connections. Cobalt‑focused sites facing lower output targets could experience hiring freezes, delayed expansions, or pressure to cut costs.

Globally, the copper surge offers some relief to grid planners, renewable‑energy developers, and EV manufacturers who have been warning about potential bottlenecks. More copper from the DRC and other producers helps temper price spikes and supports the build‑out of transmission lines, charging networks, and electric machinery.

But cobalt’s slump hits a more fragile link. Modern lithium‑ion batteries, especially those used in many electric cars and grid‑scale storage systems, still depend on cobalt for stability and energy density, even as some manufacturers shift to chemistries that use less of it. The DRC dominates global cobalt supply, so a near‑halving of output from a major player like Glencore signals tighter conditions down the chain.

For automakers and battery producers, that means more scrutiny of sourcing strategies. Some will double down on efforts to diversify away from cobalt‑intensive chemistries, accelerate recycling programs, or secure long‑term supply contracts to smooth out volatility. Others may face higher input costs that eventually filter through to vehicle prices or margins, particularly for models still using cobalt‑rich cathodes.

The DRC itself sits at the intersection of these pressures and opportunities. Its mineral wealth is central to the global energy transition, but governance challenges, conflict risks, and infrastructure shortfalls make investment hazardous. A copper boom alongside a cobalt slump could further skew attention and resources, with long‑term implications for how balanced and resilient the country’s mining‑based development becomes.

The key takeaway for markets is that the green‑tech revolution hinges not just on how much metal is in the ground, but on how reliably it can be produced, year after year, from a small number of critical regions.

Signals to watch next include updated production guidance from Glencore and other mining majors operating in the DRC, any policy changes from Congolese authorities affecting mining terms, and responses from leading EV and battery manufacturers in their sourcing and technology strategies. Price movements on global exchanges for both copper and cobalt, and shifts in long‑term offtake deals, will reveal how seriously industry players are taking this new divergence.
