Best Money Market Funds In 2026

With interest rates somewhat in flux, savers and investors might have to search a little bit harder to find the best returns from relatively safe investments such as money market funds.

Money market funds invest in short-term securities issued by governments and corporations and are available from several different brokers and fund managers, as well as some banks. Keep in mind that money market funds are a type of investment — they’re different than money market accounts, which are similar to bank savings accounts.

Investors in money market funds earn income, or a yield, from the securities that are held within the fund.

Here are some of the top money market funds to consider for your portfolio.

What is a money market mutual fund?

A money market fund is a mutual fund that invests in short-term securities with very little credit risk. These securities may be issued by governments, corporations or financial institutions in the U.S. or abroad. Money market funds are considered low-risk investments that offer current income based on the prevailing level of interest rates.

Money market funds aim to maintain a net asset value, or NAV, of $1, while providing current income. Other mutual funds, such as stock funds, may aim to increase their NAV as their underlying investments perform well, but money market funds seek stability.

Types of money market mutual funds

Money market funds are typically divided into three categories: government, prime and municipal. Here’s what you should know about each type.

Money market funds vs. money market accounts

You may have wondered if the money market accounts that banks and credit unions advertise are the same thing as money market funds. In a word, no. A money market fund is a mutual fund that invests in short-term securities while a money market account is similar to a savings account, though typically money market accounts earn a higher rate of interest than a standard savings account.

Perhaps the most important difference between money market funds and money market accounts is that money market funds are not insured by the Federal Deposit Insurance Corporation (FDIC), whereas money market accounts generally are FDIC-insured.

Money market funds come with very low risk, but there have been rare instances where funds “broke the buck,” meaning their NAV dropped below $1, such as during the 2008 financial crisis. When that happens, the fund may be liquidated and investors could receive less than $1 per share.

How to choose a money market mutual fund

Money market funds are offered by a number of different financial institutions, including banks, brokerage firms and mutual fund companies. Here are some of the key factors to consider when choosing a money market fund:

• Yield: You’ll want to compare a fund’s yield to other funds in the industry to make sure you’re getting the best return on your investment.
• Expense ratio: Funds charge an expense ratio, which comes directly out of the return you ultimately earn as an investor. All else being equal, the lower the expense ratio, the better it is for you as the investor.
• Type of fund: Consider whether you’d like to invest in a government, prime or municipal money market fund. Municipal money market funds may be particularly appealing for those in high tax brackets.
• Other fees: Be sure to pay attention to any additional fees you may be charged when buying and selling money market funds. Some brokers may charge mutual fund commissions, while others may charge fees for funds from certain fund families.

Bottom line

Money market funds aim to invest in high-quality short-term securities that provide a high level of current income while maintaining liquidity and stability. The funds may invest in government securities as well as securities issued by U.S. and foreign entities. Municipal money market funds invest primarily in tax-exempt securities.

Money market funds can be a good fit for investors looking to benefit from the current interest rate environment or saving for a short-term goal. Keep in mind that while these funds are considered low risk, they’re not FDIC-insured.
