Copper just hit an all-time high, and AI data centres are buying the land under our feet

Quick answer: copper hit an all-time high of $14,533 a ton on the London Metal Exchange on Monday, driven by tariff fears, squeezed inventories and demand from data centres, power grids and renewables. At the same time, land purchases for future AI data centres reached about $6 billion in the first half of 2026, up 79% from a year ago, and data centres now account for 27% of US development sites. The AI boom has moved from chips to copper to dirt.

The record is worth pausing on. It happened on a US public holiday with thin trading, which tells you how much pressure sits underneath this market. Traders are hedging against a proposed 15% tariff on refined copper starting January 2027, rising to 30% in 2028. The tariff gap between New York and London prices has pulled hundreds of thousands of tons of metal into American warehouses, leaving London exchange stockpiles critically low and squeezing anyone who bet against the price. Spot copper now costs more than future copper, the market's way of saying it needs metal now, not later.

The part I find more interesting: the land

While the headlines chase the copper record, the structural story is real estate. Investors spent roughly $6 billion on land for future AI data centres in the first half of 2026, a 79% jump in twelve months. Data centres are now the second largest buyer of US development sites after apartments, taking 27% of the market according to Avison Young. Rural land prices are surging, and so is the backlash, with residents organising to block projects in their towns.

"When a technology starts buying farmland, it has stopped being a software story. AI is now a physical industry, and physical industries reshape land, water, power and politics. Boards that still treat AI as an IT budget line are reading the wrong map." - Alexandra Zoë Varenzakis

Copper and land are the same trade viewed from two ends. Every data centre needs both: the metal in its cables, transformers and cooling systems, and the acreage with grid access to stand on. Copper is up about 17% over the past year precisely because the world's ageing mines cannot keep up with demand from data centres, power grids and renewables. Chile's shipments fell to their lowest in more than a year in August, despite record prices. Rio Tinto, BHP, Glencore and Zijin all posted big profit gains last quarter on the back of their copper units.

What this means for business

• —AI costs are becoming infrastructure costs: power, land, water and metal, not just model subscriptions
• —The constraint on AI growth is shifting from chips to grid connections and permitted land, both of which take years
• —Expect political friction: rural communities are already organising against data centre projects, and local opposition is now a real project risk
• —For South Africa, rich in platinum, manganese and copper-adjacent mining, a global metals squeeze is both an export opportunity and a reminder that our own grid is the bottleneck
• —Watch the US Commerce report on refined copper tariffs: it either locks in the price gap or unwinds it violently

The broader context matters too. Oil hit a six-week high as the US and Iran traded strikes on tankers, Bitcoin touched $82,272 on the debasement trade, and China injected $54 billion into its state banks. Hard assets are having a moment, and AI, for all its abstraction, is turning out to be the hardest asset story of them all: metal, land and electricity.
