VOO Hits $1T, DRAM Up 166%: ETF Flows in 2026
U.S. ETF inflows crossed $1 trillion at the halfway mark of 2026. VOO leads with $75.69B, while DRAM surges 166% since its April launch.
Key Points
- U.S.-listed ETFs absorbed $210 billion in June alone, pushing year-to-date inflows past $1 trillion at the halfway mark — a pace that would deliver a $2 trillion annual haul if sustained.
- The inflow surge is heavily concentrated: roughly 800 ETFs recorded zero net positive flows in 2026, while the top names like VOO ($75.69B YTD) and DRAM ($12.73B since April) are absorbing the vast majority of capital.
- The critical watch point is whether semiconductor ETF momentum — SOXX up 113% YTD, DRAM up 166% since April — can hold as SMH posts back-to-back losing weeks despite a partial Monday recovery.
U.S.-listed ETFs crossed $1 trillion in year-to-date inflows at the halfway mark of 2026, and the $210 billion that poured in during June alone puts the industry on pace for a $2 trillion annual haul — a figure that would shatter every record in the product category's history. The story underneath that headline number is one of extreme concentration, with a handful of funds and sectors absorbing the overwhelming majority of capital while roughly 800 products sit in net outflow or flat territory for the year.
The Winners Are Winning Bigger
Vanguard's VOO has become the single defining product of this bull market cycle, pulling in $75.69 billion year-to-date and crossing $1 trillion in total assets under management — a milestone no single ETF had reached before. State Street's SPYM follows with $36.53 billion in YTD inflows, and Vanguard's VTI has attracted $27.27 billion. The passive core equity trade is not just alive; it is accelerating. The top three equity index ETFs alone have absorbed more than $139 billion in 2026, accounting for roughly 14% of the entire industry's year-to-date intake.
The more striking data point is on the fixed income side. iShares' SGOV — the 0-to-3-month Treasury bill ETF — has pulled in $25.01 billion year-to-date despite a 10-year yield sitting at 4.55% and a Fed Funds Effective Rate of 3.63% as of July 7. Investors are not abandoning the front end of the curve even as the yield differential between 2-year Treasuries at 4.19% and 10-year paper at 4.55% represents one of the narrowest spreads of the current rate cycle. The fact that $25 billion has flowed into a near-zero-duration instrument suggests a meaningful cohort of investors is running elevated cash allocations in ETF form — tactical positioning, not long-term conviction.
SCHD, Schwab's dividend equity ETF, has attracted $10.59 billion in 2026 inflows, making it the standout in the income-oriented equity category. With CPI inflation still running at 4.2% year-over-year as of the May reading — against a core CPI of 2.8% — dividend strategies that offer some combination of income and inflation sensitivity are pulling capital from both the pure growth and pure fixed income camps. The gap between headline and core inflation at 140 basis points is wide enough to keep real-return anxiety elevated among retail allocators.
Semiconductors Are the Trade of the Year
Technology ETFs attracted $44.8 billion during the first half of 2026, with $13.4 billion flowing in during June alone — representing nearly 78% of all sector ETF inflows that month despite a late-quarter pullback in individual tech names. Within that category, semiconductors are running away from everything else. The iShares Semiconductor ETF, SOXX, collected $4.1 billion in June alone and is up 113% so far in 2026, with the bulk of that gain concentrated in Q2.
The more extreme story is DRAM — the Roundhill Memory ETF launched in April — which has become one of the fastest-growing ETFs of all time by raw dollar intake. DRAM has absorbed $12.73 billion in inflows since its April launch, with nearly $10 billion of that coming in June. Total assets have crossed $25 billion. The fund is up 166% since inception, a figure that captures both the magnitude of the AI infrastructure buildout trade and the degree to which investors are willing to concentrate exposure in a single segment of the semiconductor supply chain. Memory chips — specifically the high-bandwidth memory critical for AI accelerators — are the physical constraint on GPU performance scaling, and DRAM's flows suggest institutional money has made that thesis a core position, not a satellite bet.
The VanEck Semiconductor ETF, SMH, is the counterpoint to that enthusiasm. SMH shed 3.2% last week — its second consecutive losing week — though the fund recovered 2.3% on Monday, July 7, aided by a 4.1% gain in Marvell Technology. SMH finished the first half up more than 80%, so back-to-back weekly losses after an 80%-plus run represent normal digestion rather than trend reversal. But the divergence between SMH's recent weakness and DRAM's continued inflow momentum raises a question about selectivity: investors appear willing to hold the memory chip sub-theme while trimming broader semiconductor exposure at the margin.
Where the Money Isn't Going
The concentration story has a sharp edge. Approximately 800 ETFs recorded either net outflows or zero investor activity in 2026, and the remaining roughly 2,000 products captured only 12% of total industry inflows despite representing a majority of the market's product lineup. The iShares MSCI EAFE Value ETF, EFV, led all outflow vehicles with $5.6 billion in redemptions year-to-date — a particularly striking figure given that EFV gained 10% through the first half. Investors are pulling money from a fund that is working, which suggests the outflows are structural (portfolio rebalancing away from international value as a category) rather than performance-driven.
Commodities and currencies round out the loser list. Commodity ETFs shed $6 billion in June and currency ETFs lost $4.6 billion. WTI crude sitting at $70.48 per barrel and Brent at $69.70 as of July 3 — both well below the $80 threshold that tends to attract momentum-driven commodity ETF buying — explains much of the energy sub-sector's outflow picture. Henry Hub natural gas at $3.34 per MMBtu is similarly uninspiring for commodity fund managers trying to attract new capital.
Defense is the one sector story that cuts against the broad tech concentration narrative. The iShares US Aerospace & Defense ETF, ITA, hit an intraday all-time high this week — its first since early March — and is on pace for its longest win streak since February. AeroVironment is up nearly 30% over the past week. Drone and autonomous systems companies are acting as the sector's leadership group, and ITA's new all-time high confirms that the defense trade has legs independent of the AI semiconductor theme.
The forward-looking setup for sector ETF flows centers on one specific date: the next CPI print. Core inflation at 2.8% is within range of the Fed's target, but headline CPI at 4.2% gives the Federal Open Market Committee political cover to hold rates at current levels. If the July CPI report — due in mid-August — shows headline inflation decelerating toward the 3.5% range, the front-end cash trade in SGOV loses its urgency, and some portion of that $25 billion could rotate into duration or equity risk. That rotation, if it materializes, would be the single largest potential flow catalyst for the second half of 2026. Watch the 10-year yield: a sustained break below 4.40% would be the first signal that the SGOV-to-equity rotation trade is opening.
