Which Is the #1 Gold ETF?
Straight answer
By size and trading volume, the “#1” gold ETF is SPDR Gold Shares (GLD) — the largest and most-traded physically backed gold fund, with the deepest liquidity and options market. But “#1” by assets isn’t the same as “#1 for you.” If you trade or use options, GLD or IAU make sense; if you’re a long-term buy-and-hold investor, the lower-cost mini funds — GLDM (~0.10%) and IAUM (~0.09%) — usually keep more of your money working, because a smaller annual fee compounds in your favor over years. And all of them are paper exposure, not metal in hand, and most are taxed as collectibles (long-term gains up to 28%). There’s no single fund that’s best for everyone.
“Which is the number one gold ETF?” has a clean factual answer and a more useful honest one. The factual answer is about size. The useful answer is that the right fund depends on whether you’re trading gold or holding it — and what you’re giving up by owning shares instead of metal.
The #1 by size: SPDR Gold Shares (GLD)
If “#1” means biggest and most liquid, it’s GLD. Launched in 2004, it was the first major US gold ETF and remains the largest by assets and the most heavily traded, with the tightest bid-ask spreads and by far the deepest options market of any gold fund. When financial media name “the” gold ETF, GLD is usually the one they mean. iShares Gold Trust (IAU) is the clear runner-up — very liquid, and at roughly half GLD’s fee.
So if your question is literally “which gold ETF is the most established and easiest to trade in size,” the answer is GLD, with IAU close behind. That ranking is stable and not really in dispute. The catch is that “most traded” only matters to you if you actually need that liquidity.
Biggest vs. cheapest — the split that decides your pick
The single most important thing to understand is that the biggest fund is not the cheapest, and for many buyers cheap matters more than big. Both State Street (which runs GLD) and BlackRock (which runs IAU) launched lower-cost “mini” versions aimed squarely at long-term holders: GLDM at roughly 0.10% and IAUM at roughly 0.09%, against GLD’s ~0.40% and IAU’s ~0.25%. Treat these figures as approximate and verify the current expense ratio on the fund’s own site before buying.
That fee gap is small in any one year but compounds. On a $25,000 holding, GLD’s ~0.40% is about $100 a year; IAUM’s ~0.09% is closer to $22 — the same gold, the same price moves, roughly $78 a year of difference for owning the cheaper wrapper. Over a decade that adds up, and there’s no extra gold inside the pricier fund to justify it. The trade-off is the other direction: the mini funds are perfectly liquid for ordinary investing but don’t have GLD’s depth or options ecosystem.
So the honest framing is two questions, not one ranking:
- Are you trading or using options? Liquidity and the options chain win — GLD (deepest) or IAU (strong liquidity, lower fee).
- Are you holding for years? The expense ratio wins — GLDM (~0.10%) or IAUM (~0.09%), where the fee savings are essentially the whole game.

The catch every gold ETF shares
Before you crown any fund, two facts apply to all of them — and they’re easy to miss.
This is why “#1 gold ETF” can be the wrong question entirely. If your real goal is metal in hand — an asset with no counterparty that you can physically access — no fund is the answer, and you’d buy physical from a vetted dealer instead. Silver buyers face the same paper-vs-metal trade-off; our guide to physical silver vs. silver ETFs covers the wrinkles specific to silver.
So, which one?
There isn’t a universal winner, and anyone who tells you there is usually isn’t accounting for how you’ll use it. The defensible answer: GLD is #1 by size and liquidity; the lowest-cost choice for a long-term holder is IAUM or GLDM; and if you want gold you can hold, skip the ETF altogether. Whichever you pick, the fund only decides how cheaply and easily you hold gold — not how much you should own. Most advisors suggest capping precious metals at roughly 5%–10% of a portfolio, ETF or coin.
What is the #1 gold ETF?
By assets and trading volume, SPDR Gold Shares (GLD) is the largest and most-traded physically backed gold ETF, with the deepest liquidity and options market — so it’s “#1” by size. iShares Gold Trust (IAU) is the runner-up at a lower fee. But “#1 for you” depends on your goal: long-term holders often do better in the lower-cost mini funds, GLDM (~0.10%) or IAUM (~0.09%).
Is GLD better than the cheaper mini funds?
It depends on use. GLD has the deepest liquidity and the most active options market, which suits traders and large positions, but it charges roughly 0.40% a year. For buy-and-hold investors who don’t trade options, the lower-fee mini funds — GLDM around 0.10% and IAUM around 0.09% — usually make more sense, because the fee savings compound over time. Verify current expense ratios before buying.
Are gold ETFs taxed like regular stocks?
Usually no. The IRS treats most physically backed gold ETFs as collectibles, so long-term gains can be taxed at a rate up to 28% — higher than the 0%–20% on ordinary stocks, and the same as physical gold. Buying gold through an ETF does not generally lower your tax rate. This is general information, not tax advice; confirm the details for your situation.
Should I buy a gold ETF or physical gold?
An ETF gives cheap, liquid, hands-off exposure inside a brokerage account — easy to trade and rebalance, nothing to store. Physical gold gives you metal you control with no counterparty, at the cost of dealer premiums and storage. If your reason for owning gold is to hold something outside the financial system, an ETF doesn’t deliver that. Many investors own both.
