Why Gold ETFs Belong in a Portfolio
Owning gold used to mean owning the metal. You buy coins or bars, then you deal with storage. Insurance costs money every year. Selling later means finding a dealer and taking whatever price they quote that day.
Gold ETFs trade all of that for convenience. You buy shares in a normal brokerage account or an IRA, the fund tracks bullion, and shares are traded whenever the stock exchanges are open. Many investors use gold to protect a portfolio against inflation and the kind of market stress where stocks and bonds fall together. That is the whole case. You never hold a single ounce yourself. And if you are deciding where a specific $1,000 should go, we answered that question on its own page.

How Physical Gold Funds Work
A share of a physically backed gold ETF is structured as a claim on real metal in a vault. It is not a futures contract or a debt security, which is where confusion about precious metals funds starts. The trust buys physical gold, stores it, and issues shares against what it holds. Price tracks the metal closely after fees.
Nothing about the structure is complex, so cost ends up being the main thing separating one gold ETF from another. Two gold ETFs holding the same physical gold differ mostly by what they charge.

What Gold Bullion Backing Means
Gold bullion backing has one wrinkle worth understanding before investors buy shares. The trust pays its expenses by selling a small amount of the metal it holds, month after month. So the gold bullion behind each share slowly declines, even on a day when the price does nothing. Nothing is hidden about the process. It is the honest version of the line that gold pays no dividends, so there is no income to tax while you hold.
The 5 Best Gold ETFs of 2026
Here are the five, in order of size. Four of them hold physical gold and one holds miners. For a sense of how these funds rank across the whole market, see the largest ETFs in the market by assets.
SPDR Gold Shares (GLD): Best for Active Traders
GLD launched on November 18, 2004, the first US gold ETF and still by far the largest, with $145.98 billion in assets under management as of August 12, 2026.1 Size is the product here. It carries a large listed options market for investors who trade around a position. Its own 30-day median bid/ask spread is 0.01%.
You pay 0.40% a year for that, the highest expense ratio of the four physically backed funds. On $10,000, for example, that is $40 annually. For a trader moving in and out, $40 is noise against execution quality. Investors holding twenty years see that $40 compound against them, even when the returns underneath are compounding too. That is why the rest of this list exists.
iShares Gold Trust (IAU): The Lower-Cost Alternative
IAU arrived two months after GLD, on January 21, 2005, second largest here at $65.01 billion in total assets. The sponsor fee is 0.25% against GLD’s 0.40%.2 Same $10,000, and now the cost is $25 a year instead of $40.
Its own 30-day median bid/ask spread is 0.01%. For most investors that combination of a lower expense ratio and heavy trading has been enough. IAU was the default answer among gold ETFs for years. Then the newer minis showed up and undercut it.
SPDR Gold MiniShares (GLDM): Best for Long-Term Investors
State Street runs GLDM alongside GLD, holding the same metal under the same structure, at a gross expense ratio of 0.10%.3 That is a quarter of GLD’s fee. On $10,000 you pay $10 a year.
GLDM launched June 25, 2018 and now holds $30.39 billion, so the cheap option stopped being the small option a while ago. Its own 30-day median bid/ask spread is 0.01%. Run that fee difference against GLD across thirty years and the advantage stops looking cosmetic. This is the fund I point investors toward when they are buying gold and have no plans to touch it.
VanEck Gold Miners (GDX): Mining Company Exposure
GDX is a different animal. Buying it buys 66 gold mining companies, not gold.4 Miners carry operating costs, debt, country risk and management decisions that a bar of metal never has. When gold prices run, good miners tend to run harder. A company with a bad quarter can still fall while the metal holds steady.
The fee is 0.51%, highest in this lineup, on $27.99 billion in total net assets. The top 10 holdings are 61.53% of the fund, so this is a concentrated stock position wearing a commodity label. It pays a small distribution too, which no physical gold fund does. Read it alongside how many ETFs you actually need first.
iShares Gold Trust Micro (IAUM): The Lowest Expense Ratio
IAUM carries the lowest expense ratio on this page at 0.09%, one basis point under GLDM.5 On $10,000 that works out to $9 a year against GLDM’s $10.
The saving is real. It is also one dollar. IAUM launched June 15, 2021, the newest of these top gold ETFs, and at $7.47 billion the smallest. Its own 30-day median bid/ask spread is 0.02%. None of that is a warning to investors. It is a shorter record with less size behind it. If the cheapest possible number is what you want, this is the one.
How the Top Gold ETFs Compare
| Fund | Issuer | Expense Ratio | Net Assets | Inception |
| SPDR Gold Shares (GLD) | State Street | 0.40% | $146B | November 18, 2004 |
| iShares Gold Trust (IAU) | iShares | 0.25% | $65B | January 21, 2005 |
| SPDR Gold MiniShares (GLDM) | State Street | 0.10% | $30B | June 25, 2018 |
| VanEck Gold Miners (GDX) | VanEck | 0.51% | $28B | May 16, 2006 |
| iShares Gold Trust Micro (IAUM) | iShares | 0.09% | $7B | June 15, 2021 |
Net assets as of August 12, 2026.
Read the data in that table left to right and one pattern jumps out. The older gold ETFs cost more, and the newer ones were built to undercut them. The percentage you pay ranges from 0.09% to 0.51%. Size is a different story. Assets follow age more than price here, and the largest gold ETFs were already large before the cheap ones launched. Cost is one input investors weigh when they build an ETF portfolio that can last a lifetime, not the only one.
What Moves Gold Prices
So what actually moves gold prices? Inflation is the force everybody names first. Gold has long been treated as a hedge when price increases run hot. Central banks around the world are the second. They have been steady buyers of precious metals, which supports demand in a way news headlines rarely capture. Third is stress: wars, elections, anything that makes the dollar look less certain. Worries about US federal debt and the buying power of your dollars show up in gold prices.
Silver and other precious metals often move alongside it, rarely by the same amount. Gold moves differently from stocks, bonds and other commodities, which is one reason it appears in models like Ray Dalio’s all weather portfolio.

Gold as a Safe Haven Asset
Gold has a long record as a safe haven asset, holding value while other things around it fall. Here is the honest limit on that. Gold ETFs are volatile in their own right. Gold pays no dividends and no interest, so every dollar of return has to come from gold prices going up.
A stock can pay you while you hold it. With gold, you are waiting on price and nothing else. Investors weighing it against the leading Bitcoin ETFs are asking a similar question about scarcity, and neither answer generates cash.
My #1 Pick and Why
GLDM is my pick. IAUM’s fee is the first thing to deal with. 0.09% beats 0.10%, and I am not choosing the more expensive gold ETF by accident.
One basis point on $10,000 is one dollar a year. GLDM brings $30.39 billion in assets against IAUM’s $7.47 billion, eight years of history against five, and a sponsor whose gold franchise goes back to 2004. That is worth more to me than a dollar.
Trade actively and GLD is the better tool, with 0.40% as the price of admission. IAU and IAUM are both perfectly good holdings for most investors. None of this works without a brokerage account that fits how you invest.

What Gold Costs You at Tax Time
The IRS treats physically backed gold ETFs as collectibles. Net capital gains from selling collectibles are taxed at a maximum 28% rate, above the long-term rates that apply to most stock and fund gains.6
That difference is a strong argument for investing in these funds inside an IRA rather than a taxable account. Our breakdown of capital gains tax rates covers which rate applies to what.
Where This Leaves Your Gold Allocation
Match the gold ETF to how long you plan to hold it. Buying and holding for years? Take the low expense ratio and let it work for you. Traders pay for liquidity instead and stop worrying about the fee difference. Mining exposure is a separate decision, and GDX is the fund suited to it.
One honest caveat to close on. Gold has had a strong run, and record highs make past performance look obvious in hindsight. Nothing on this page promises the next stretch resembles the last one. Size the position so you would be comfortable either way. Once gold has its place, the next question is what carries the income side of your portfolio, and the best bond ETFs to buy in 2026 answers it.
