Copper at record highs.

In the week of September 8–10, 2026, copper set fresh records on the London Metal Exchange (LME) — the global benchmark market where copper is bought and sold. The price ran roughly $14,510 to $14,779 per metric ton, according to reporting from the Wall Street Journal. That is the highest copper has ever traded, and it leaves the metal up about 16% since the start of the year.

A quick word on the unit, because it matters for sellers: a metric ton is 1,000 kilograms, and it is how the world copper market quotes prices. Benchmark figures on this page are quoted the way the market quotes them — per metric ton. Ironcrest does not publish per-pound prices; when you ask for an offer on your copper, it is priced against the current market, not against a yard-board number from last month.

Records get set when demand is strong and buyers are nervous. Copper has both right now: real, physical demand from the AI buildout, the power grid, and electrification — plus a market-wide scramble to buy metal before a possible US tariff changes the math. Here is what is going on, in plain language.

Copper is the metal electricity runs on. It carries current with less loss than almost anything else, so it shows up everywhere power is made, moved, or used — and three big trends are all pulling at once.

AI and data centers. An AI data center is basically a giant electrical machine. The servers themselves, the busbar and wiring that feeds them, the transformers stepping power down, the cooling systems — every part of a new data center is copper-heavy. And the buildout is enormous: hyperscalers are adding capacity at a pace the power industry has never seen, and each new hall needs tons of copper before it ever switches on. See our page on selling electrical equipment for what these facilities buy and retire.

Grid buildout. The US power grid is being rebuilt and expanded — new transmission lines, new substations, upgraded distribution. Grid work is some of the most copper-intensive construction there is: underground cable, busbar, grounding wire, transformer windings. Utilities are spending at levels that keep rod mills and cable makers busy for years.

Electrification. Electric vehicles, solar and wind farms, heat pumps, EV chargers — the shift to electrified everything runs on copper. An EV carries multiples of the copper in a gas car, and every megawatt of new solar or wind needs cable to get that power to the grid. None of these trends has an off switch, which is why copper demand keeps absorbing new supply.

“Tariff front-running” is market jargon for something simple: buying now to beat a tax that might land later. If a 15% US tariff on refined copper takes effect in January 2027, copper bought today costs less than copper bought after the tariff lands. So American buyers — wire makers, rod mills, fabricators — have been stockpiling metal while they can.

That stockpiling shows up in the numbers: COMEX copper inventories hit a record of roughly 675,000 tons as buyers front-ran the possible tariff. (COMEX is the US futures market for copper — its warehouses are where American buyers park metal.) When everyone rushes to buy at once, that extra demand pushes prices up on top of the real demand from data centers and the grid. It is the double punch behind this month’s records: genuine copper consumption, plus speculative buying from people trying to get ahead of policy.

For a fuller timeline of the tariff story — including the July 2025 tariff shock and the record US import waves — see our copper market trends page.

The policy hanging over the market is this: the US is considering a 15% tariff on refined copper that could take effect January 1, 2027. Refined copper is the pure cathode and shapes that mills melt and draw into wire and cable — so a tariff would raise the cost of imported copper in the United States, which would tend to support US prices.

But it is not a done deal. As of early September 2026, the White House was still hesitating on the decision, according to Barron’s. That uncertainty is exactly why the front-running is happening — buyers are not waiting to find out. If the tariff lands, imported refined copper gets 15% more expensive in the US; if it doesn’t, the record stockpile of front-run metal has to find a home. Either way, copper is trading at historic levels right now, and sellers holding physical copper are selling into a record market. Ironcrest does not make price forecasts — but records are records, and this is where the metal stands today.

Record prices matter most to the people with copper sitting around. That could be a lot of things:

• Leftover wire and cable — full or partial reels, cutoffs, and pulls from finished electrical jobs.
• THHN and Romex cutoffs — the short ends every electrician’s shop accumulates.
• Copper busbar — flat bars pulled from switchgear, panelboards, and MCC lineups.
• Copper tubing — from HVAC, plumbing, and industrial takeouts.
• Transformer and demo copper — windings and conductor recovered from tear-outs and decommissioned equipment.

Every pound of that material is priced against the same record market. When benchmarks are at all-time highs, the copper in your shop, yard, or truck is worth more than it was a year ago — and possibly more than it will be worth later. Nobody can say where prices go next, and this is not a price forecast. It is simply the math of selling into strength: the time to ask what your copper is worth is when copper is worth the most.

One practical note for anyone holding copper: keep it separated. Bare bright, #1, and #2 wire are different grades with different values — mixed piles get priced as the lowest grade in the pile. Our copper grades guide walks through what separates them.

Selling your copper to Ironcrest is three moves:

1. Text photos of the copper. Photograph the wire, cable, or busbar — close-ups of the copper itself plus a wide shot showing how much there is. Include the city and state, a rough weight or count, and your timing. Email [email protected] or call or text 312-880-8174.
2. Get today’s offer. Ironcrest reviews the photos and prices your copper against the current market — same-week turnaround, no waiting on a committee. You get one number for the lot.
3. We pick it up — paid on the spot. Ironcrest runs nationwide, so distance is not a dealbreaker. We coordinate pickup from your shop, yard, or job site, and you are paid on the spot.

No appointments three weeks out, no hauling it to a yard yourself. Track the market if you like — but when you are ready to sell into it, send the photos first.

How high did copper actually go in September 2026?

LME copper traded roughly $14,510 to $14,779 per metric ton in the week of September 8–10, 2026, according to the Wall Street Journal — the highest prices copper has ever traded at, and up about 16% year-to-date.

Why is copper at record prices right now?

Two forces at once: real physical demand from AI data centers, grid buildout, and electrification — plus tariff front-running, as US buyers stockpile copper ahead of a possible tariff, pushing COMEX inventories to a record of roughly 675,000 tons. That extra buying layered on top of genuine demand is what set the records.

What does “tariff front-running” mean?

Buying now to beat a tax that might land later. If a 15% US tariff on refined copper takes effect in January 2027, copper bought today costs less than copper bought after the tariff. So American buyers have been stockpiling metal while they can — and that rush of buying has pushed prices up further.

Is the January 2027 copper tariff actually going to happen?

It is still undecided. A 15% tariff on refined copper could take effect January 1, 2027, but as of early September 2026 the White House was still hesitating on the decision, according to Barron’s. The uncertainty itself is moving the market — buyers are stockpiling rather than waiting to find out.

What do record copper prices mean for someone holding scrap or surplus copper?

Your material is priced against a record market — leftover wire and cable, THHN and Romex cutoffs, busbar, copper tubing, and transformer or demo copper are all worth more against record benchmarks than they were a year ago. This is not a price forecast; it is the math of selling into strength. Send photos for today’s offer, priced against the current market.

What copper does Ironcrest buy, and how do I get an offer?

Ironcrest buys bare bright, #1, and #2 copper wire, insulated wire and cable, THHN and Romex cutoffs, copper busbar, copper tubing, and transformer copper — single cutoffs to full reels and truckloads, with nationwide pickup. Text photos of your copper to 312-880-8174 or email [email protected] and get today’s offer. You are paid on the spot.
