Is IAUM a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The case for IAUM is simple: low-cost, diversified exposure to Spot gold price (LBMA Gold Price) at a 0.09% expense ratio, anchored by names like GOLD. If that is the exposure you want and you do not already own most of it through another fund, IAUM is a strong core holding. The catch is concentration in its top names and overlap with broad-market funds you may already hold. Whether it is a buy comes down to whether you want Spot gold price (LBMA Gold Price) and at what cost. Not a recommendation; Walnut is not an investment adviser.
What are you buying with IAUM?
IAUM is the iShares Gold Trust Micro, a physically backed gold ETF that tracks the spot gold price at a 0.09% expense ratio, the lowest among major gold funds. It holds allocated gold bars like IAU but at a smaller per-share price and a lower fee, aimed at cost-focused long-term holders. Its closest rival is GLDM at 0.10%; both undercut IAU (0.25%) and GLD (0.40%).
Largest holdings (approximate as of mid-2026; verify on BlackRock iShares's fund page):
| Rank | Ticker | Company | % of IAUM | |

What's the case for IAUM?
IAUM is the iShares Gold Trust Micro, BlackRock's low-fee micro version of IAU. It holds allocated physical gold bullion and tracks the spot gold price at a 0.09% expense ratio, the cheapest among major gold ETFs. It is the same physical gold as IAU (0.25%) but at a lower fee and a smaller per-share price aimed at cost-focused and fractional buyers. Its direct rival is State Street's GLDM at 0.10%, which IAUM narrowly undercuts, while both are far below GLD's 0.40%. Like all bullion funds, it holds no stocks and pays no dividend.
In its favour: it gives you Spot gold price (LBMA Gold Price) exposure in one ticker at a 0.09% expense ratio, which is simple to hold and cheap to own.
What should you weigh before buying IAUM?
- Cost vs alternatives: 0.09% is the fee; compare it to funds tracking a similar index.
- Concentration: check how much of IAUM sits in its largest holdings (GOLD).
- Overlap: if you already own a broad-market fund, you may already hold much of this.
- Tracking scope: IAUM only gives you Spot gold price (LBMA Gold Price); it will not capture what sits outside that index.
How do you decide if IAUM is a buy?
The useful question is rarely “will IAUM go up?” It is “does this exposure fit my plan, at a cost I am happy with, without doubling up on what I already own?” Walnut connects your real brokerage so you can see exactly how IAUM would overlap with your current holdings, analyze it by chatting through Claude or ChatGPT, and place any trade yourself. You stay in control.
The bottom line on IAUM
The bottom line: IAUM is a low-cost core building block for Spot gold price (LBMA Gold Price) exposure, not a tactical bet on a single name. If you want Spot gold price (LBMA Gold Price) exposure and the 0.09% fee is competitive for you, it does its job well. If you already own that exposure through another fund, adding it mostly doubles a fee without adding diversification. Decide from your goal and your existing holdings, not from where the market sat last week. Walnut is not an investment adviser.

FAQ

How do I decide if IAUM is right for me?
