Fidelity Launches Its First ETF Share Classes: A Simple Guide

What Happened?

On June 18, 2026, a big company called Fidelity Investments added three new ETF options to its list of things you can invest in. Think of an ETF (Exchange-Traded Fund) like a basket you can buy on the stock market that holds lots of investments inside it.

These new baskets are "share classes" tied to older mutual funds (another type of investment basket). That means they follow the same exact strategy and history as the older mutual fund versions.

The three new ETFs are:

• Fidelity Intermediate Municipal Income ETF (FIMU)
• Fidelity Real Estate Income ETF (FREI)
• Fidelity Short-Term Bond ETF (FSTB)

Fidelity told everyone about this on June 15, 2026.

Meet the New ETFs and Their Costs

Each ETF has a "expense ratio" — that’s like a small yearly fee taken from your investment to pay for running it. Here are the estimated fees:

• FIMU: 0.30%
• FREI: 0.57%
• FSTB: 0.20%

These fees are low enough to be competitive with similar products.

What does each one invest in?

• FIMU: At least 80% goes into municipal securities (basically loans to cities or states) that are free from federal income tax. Managed by Cormac Cullen, Michael Maka, and Elizah McLaughlin.
• FREI: At least 80% goes into debt and income-producing stocks of real estate companies. Managed by Bill Maclay.
• FSTB: Focuses on safe-grade debt that finishes (matures) in 5 years or less. Managed by Dave DeBiase, Robert Galusza, and John Mistovich.

Important Point: All three ETFs hold the same stuff and have the same track record as their mutual fund twins.

Fidelity’s Bigger Picture

Fidelity now has 84 ETFs and ETPs (similar basket products) with $172 billion managed as of May 31, 2026. That’s a lot of money!

If you already own the older mutual fund versions on Fidelity’s platform, you can switch to the new ETF class:

1. You can convert your shares.
2. It is non-taxable — meaning you don’t owe taxes just for switching.
3. This makes the move easy and smooth for current investors.

Important Point: Existing mutual fund shareholders can switch to the ETF version without paying taxes on the switch.

The ETF Share Class Trend Gains Momentum

Fidelity is not alone. Other big managers are doing the same thing because of a special permission (called exemptive relief) that lets mutual funds offer ETF share classes.

• Dimensional Fund Advisors launched the first actively managed ETF share class in March 2026.
• Thornburg Investment Management launched two in April 2026. Since its first active ETFs in Jan 2025, Thornburg’s ETF platform grew to over $600 million.

Why Do People Like ETF Share Classes?

They can help with taxes!

• J.P. Morgan says mutual fund investors may get better tax efficiency (though not guaranteed).
• ETFs can do "in-kind redemptions": instead of selling investments for cash (which can create taxes), they trade out low-basis securities (ones that grew a lot) without triggering taxable gains.
• This protects shareholders from tax bills when other people leave the fund.
• The ICI (Investment Company Institute) says dual share classes can also bring economies of scale (cost savings from size) and tax-smart transitions.

Important Point: The tax benefit comes from ETFs shuffling out investments without selling them for cash, avoiding taxable gains.

This follows a trend by other firms using ETF share classes for better tax efficiency via in-kind redemptions. Fidelity’s platform now holds $172B across 84 products.
