U.S. ETFs Have Already Set a New Annual Inflow Record, and Investors Kept Buying in October

U.S.-listed ETFs broke their full-year inflow record with a full quarter left on the calendar, and two independent trackers confirm it. State Street Investment Management counted record year-to-date inflows of $1.54 trillion through September 2026. That topped the 2025 record of $1.52 trillion. (Inflows are the new money investors put into funds, minus what they pulled out.)

ETFGI, a separate research firm, counted $1.56 trillion of U.S. ETF net inflows through September. ETFGI compares that with $1.50 trillion for all of 2025. The two firms measure flows differently, so their totals don’t match, but each one shows the previous year’s record broken.

Why it matters to you: ETFs are now the default tool for retail investors, and that money is reshaping which funds win, including the S&P 500 funds sitting in many retirement accounts.

Investors Kept Buying Even as October Stocks Fell

TD Securities, using Bloomberg data, counted $203.8 billion of U.S. ETF inflows in October. TD Securities ranks that as the second-strongest month in industry history, behind the $250 billion gathered in December 2025.

TD Securities puts year-to-date net flows through October 30 at approximately $1.73 trillion, the largest on record at this point in any year.

The buying came during a down month. According to InvestmentNews, the S&P 500 declined 0.93% in October, and the Nasdaq 100 dropped 6.65%.

Bonds Set a Record While S&P 500 Investors Swapped Funds

Fixed income ETFs pulled in a record $71.0 billion in October, according to TD Securities. Municipal bond ETFs, which hold debt issued by states and local governments, had their best month ever at $21.1 billion.

Active ETFs, where a manager picks investments instead of copying an index, drew $613.7 billion year to date through October 30. S&P 500 funds saw money move in both directions. The Vanguard S&P 500 ETF (NYSEARCA:VOO) led every ETF with $23.7 billion in October inflows. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) posted its category’s largest outflow at $6.9 billion, according to TD Securities.

TD reads that as investors rotating between S&P 500 wrappers while staying in the index, including toward lower-cost options such as State Street SPDR Portfolio S&P 500 ETF (NYSEARCA:SPYM), per TD’s analysis.

Fees explain much of the pull. An expense ratio is the annual fee a fund charges as a share of your investment. SPY’s is 0.0945% per its March 17, 2026 fact sheet, versus 0.03% for VOO and 0.03% for IVV. On $10,000, that’s about $9.45 a year for SPY against $3 for the other two, all tracking the same index.

SPY closed at $756.76 on November 11, up 10.97% year to date but down 2.74% over the past month. VOO sat at $695.62 and IVV at $760.17.

Some of October’s Money Was Recycled Cash

TD cautions that tax-loss harvesting likely inflated October’s total. That’s the practice of selling losing positions to lock in a tax deduction, then putting the cash in ETFs. Some of the flow is existing money moving between funds.

Additionally, not every category grew. U.S.-listed crypto ETFs saw $2.3 billion of outflows in October, and gold ETFs lost $699 million.

Flow records describe where money went. They carry no forecast for market returns, and flows can reverse quickly when sentiment shifts.

What Retirees and Near-Retirees Should Check Now

Matthew Bartolini of State Street Investment Management projects full-year 2026 ETF inflows of $2.3 trillion. Treat that as a forecast.

For investors at or near retirement, the useful takeaways are practical. Check the expense ratio on any S&P 500 fund you hold, since identical index exposure can carry different fees. Read how an active ETF picks investments before buying one. And remember that a fund’s popularity says nothing about whether it matches your income needs or risk tolerance.
