The ETF industry has carried its record-breaking momentum from 2025 into the new year, surpassing $100 billion in net flows before the end of January.
By the end of the month, flows into U.S. ETFs totaled $165 billion — the most ever for a January and more than the last three Januarys combined, according to State Street investment Management.
This sprint to start 2026 comes as investors navigate a shifting equity landscape characterized by a notable move away from the mega-cap concentration that dominated the past three years. For advisors, the data suggests a tactical pivot toward broader market participation and international exposure.
A Broadening Market Horizon
While the S&P 500 managed a respectable 1.5% gain in January to close at 6,939, the headline number masks a significant rotation under the surface. For the first time in several quarters, the market broke free from its mega-cap tether. The S&P 500 Top 50, which tracks the largest companies in the index, actually fell 0.5% during the month.
In contrast, mid- and small-cap stocks saw a powerful resurgence. The S&P SmallCap 600 gained 5.6% in January alone, nearly matching its total return for all of 2025, according to S&P Global. Similarly, the S&P MidCap 400 added 4.1%, signaling that participation is finally broadening across market capitalizations.
Sector Performance and January ETF Flows Beneficiaries
January’s performance was led by cyclical and value-oriented sectors. Energy, materials, consumer staples, and industrials were the top performers, while the previously dominant information technology and financials sectors lagged. This rotation is clearly reflected in the flow data, as advisors seek out diversification through equal-weighted and broad-market exposures.
The top 10 ETFs by net inflows in January 2026 demonstrate a concentrated preference for broad-market core holdings and a strategic expansion into international equity. Leading the pack, the Vanguard S&P 500 ETF (VOO) gathered $16.6 billion in net flows, followed by significant emerging market interest in the iShares Core MSCI Emerging Markets ETF (IEMG) at $8.9 billion. The State Street SPDR Portfolio S&P 500 ETF (SPYM) took the third spot with $7.9 billion, while international diversification continued with the Vanguard Total International Stock ETF (VXUS) attracting $6.2 billion.
Fixed income and total market exposures also saw healthy participation, with the Schwab Mortgage-Backed Securities ETF (SMBS) pulling in $6.0 billion and the Vanguard Total Stock Market ETF (VTI) adding $5.6 billion. Investor appetite for emerging markets remained high as the iShares MSCI Emerging Markets ETF (EEM) saw $4.1 billion in inflows, narrowly outpacing the Invesco S&P 500® Equal Weight ETF (RSP) at $4.0 billion. Rounding out the top ten were the State Street Financial Select Sector SPDR ETF (XLF) and the Vanguard Growth ETF (VUG), which recorded inflows of $3.1 billion and $2.8 billion, respectively.
RSP’s $4 billion in net flows was particularly notable, as it was a stark contrast to its net outflows in 2025. This may suggest advisors are actively de-risking from Magnificent Seven concentration.
The Rising Stars of 2026
While the heavyweights dominated in absolute terms, several smaller funds saw explosive growth relative to their size. Among ETFs with assets under management greater than $50 million, a select group of rising stars outpaced the field in percentage-based flows.
The Franklin Small Cap Enhanced ETF (FSML) saw significant interest as its active multi-factor approach to small-caps resonated during the Russell 2000's improvement, while the Xtrackers S&P 100 Ex Top 20 ETF (XOEX) directly targeted the anti-concentration trend by excluding the 20 largest market-cap giants. In developing markets, the AB Emerging Markets Opportunities ETF (EMOP) reflected a clear shift toward active management in volatile regions. Meanwhile, the Sterling Capital Hedged Equity Premium Income ETF (SCEP) tapped into ongoing demand for downside protection paired with yield, and the Sterling Capital Multi-Strategy Income ETF (SCMC) provided a flexible active fixed-income play for a shifting rate environment.
