8 Energy Transition ETFs With at Least $1bn in Assets
GSR’s US-listed energy transition ETF list includes 8 funds with at least $1 billion in net assets. The screen compares their fees, index mandates and largest holdings, with a dated source for each figure.
Electricity transmission infrastructure is one of the themes represented in the screen.
The screen identifies 8 funds in GSR’s US-listed energy-transition ETF universe with at least $1 billion in assets. They cover uranium and nuclear power, grid infrastructure, copper, rare earths and strategic metals, lithium and batteries, and clean energy.
The results compare fund size, annual fees and portfolio mandates. AUM measures the scale of the fund. It does not establish how diversified the holdings are, how cheaply the ETF can be traded or whether its exposure fits a particular portfolio.
TAN is excluded after Invesco reported fund market value of $884.53 million as of October 1, 2026, below the $1 billion threshold.

What the size screen shows
Nuclear exposure takes several forms. URA, NLR and URNM combine uranium businesses, electricity generators, equipment suppliers and physical uranium in different proportions. Their holdings show which parts of the industry dominate each portfolio.
The minerals funds serve wider markets. COPX, REMX and LIT connect to electrification through raw materials and batteries. Their businesses also depend on commodity cycles and demand from other industries. GSR’s rare earth stocks list compares the listed miners, processors and magnet makers in that sector.
Infrastructure and generation offer different businesses. GRID focuses on electricity networks and related equipment, while ICLN brings clean-power generation and technology into the results. Compare those mandates before using fund size to narrow the shortlist.

LIT tracks the Solactive Global Lithium Index, spanning lithium mining and refining through battery production.8

Screen limitations
A large asset base does not guarantee tight bid–ask spreads or sufficient trading depth for every order. The liquidity of an ETF’s underlying securities also matters, as Vanguard explains in its ETF liquidity research.9
These are thematic equity funds. Industry concentration, commodity cycles, interest rates, regulation and currency movements can affect their holdings. Owning several funds in this table may still leave substantial overlap. The screen does not measure that overlap or forecast returns.
The universe is GSR’s US-listed energy-transition ETF list. Asset figures have individual observation or retrieval dates, shown with their sources. Holdings have separate dates and may have changed. Prices and flows can move funds across the threshold.
Conclusion
The $1bn threshold narrows the list by fund size. Compare the index mandate and largest holdings next: these funds invest in different businesses even where their energy-transition themes overlap.
