The AI trade everyone is talking about is silicon. The AI trade that almost no one talks about is the copper that carries electrons from a substation to a GPU rack, and that Global X Copper Miners ETF (NYSE:COPX) is the cleanest liquid vehicle for ownership. COPX holds on to the companies that are digging the stuff out of the ground, and as software valuations continue through another phase of expansion, the fund has quietly returned about 69% over the past year, versus about 20% for the S&P 500.

What COPX actually has and why it is important for AI
The fund tracks the Solactive Global Copper Miners Index and focuses on dozens of large producers. Most of its holdings are foreign companies that are directly or indirectly involved in copper mining or at least have a reasonable exposure to it.
The AI connection is physical. A single traditional data center requires thousands of tons of copper and megawatts of dedicated power capacity, and the National Electrical Contractors Association told Congress in April that data center energy use could account for 9.1% of total U.S. electricity use by the end of the decade.
Every substation, every transformer, and every meter of high-voltage cable that powers a GPU cluster is copper intensive. Global copper consumption is expected to rise from 26 million tons in 2022 to 43 million tons in 2050, driven by AI data centers and electrification.
Does the fund support the thesis?
Yes. COPX is up 136% over five years and about 513% over 10 years, well above the S&P’s 85% and 323% over the same period. Freeport McMoRan (NYSE:FCX | FCX Price Prediction), the second-largest U.S. stock, is up about 34% over the past year. The largest US holding is Southern Copper (NYSE:SCCO), up 72% over the past year. The fund saw nearly $2 billion in new inflows this year, bringing assets to about $7.76 billion.
The 0.65% expense ratio doesn’t compare favorably to market-wide ETFs, but no S&P fund offers this factor. Supply supports the case.
The Democratic Republic of Congo, the world’s second-largest producer, saw copper exports rise 4.8% in the first quarter and expects little major production damage from disruptions in the Middle East in 2026. Consolidation is afoot: a sale of South32 assets would boost Copper to about 55% of its EBITDA, making it a more obvious takeover target, while BHP’s new CEO takes on the classic copper dilemma of building expensive new mines or buying existing assets. In this scenario, miners tend to overpay and COPX has most of the plausible sellers.
The compromises you actually make
Cyclicality is the name of the game. The COPX has fallen nearly 3% over the past month, a reminder that copper miners react violently to any whiff of growth fluctuations. U.S. real GDP fluctuated from 4.4% in mid-2025 to 0.5% in the third quarter to 2.1% in 2026, and copper stocks are amplifying these moves.
- Growth sensitivity. When global industrial activity slows, copper mining companies fall faster than the underlying metal. This fund is a call option on synchronized growth plus AI investment cycle.
- Concentration and responsibility risk. Five companies make up half of the portfolio, and much of the production comes from Chile, Peru and the Democratic Republic of Congo. Permits, license fees and network access are political decisions.
- The technology counterpoint. Jensen Huang argued in June that fiber and silicon photonics are becoming increasingly necessary due to copper’s limitations at higher bandwidths. Rack-to-rack connections can move; Copper from the substation to the rack is not the case.
Who COPX is suitable for and who should avoid it
COPX fits the profile of a satellite position for investors who already have broad equity index funds and want to specifically participate in electrification expansion without preparing miners for stock picking. It fits well with a large software or semiconductor position and covers the physical bill that the AI story ultimately has to pay.
The fund pays low returns and fluctuates widely, making it a poor fit for retirees drawing on their portfolio. A 20% drop in China PMI data due to a bad month is a routine outcome here, which rules this out for anyone who can’t tolerate this volatility. Everyone else gets a true pick-and-shovels trade at a fair price, provided they treat it as a cyclical position with a defined exit.
