[![sumit](/sites/default/files/styles/author_image_icon/public/2023-03/Sumit_0.png?itok=SO-7S5SH "sumit")](/authors/sumit-roy) [By Sumit Roy ](/authors/sumit-roy) Feb 28, 2023 Edited by: Sumit Roy [ + Follow ](/etf/login) Share Email LinkedIn Facebook X (Twitter) googletag.cmd.push(function() { googletag.display('js-dfp-tag-article_page_302x26'); }); Loading On Tuesday, I took a look at the [fastest-growing ETFs](https://www.etf.com/sections/features-and-news/small-etfs-gaining-traction-2023) of the year. Those were funds that are seeing large inflows as a percentage of the assets under management they started the year with. Most of those ETFs started with relatively low levels of assets—$10 million or less, in most cases. But their inflows this year have still been impressive, taking what were tiny funds into the tens of millions or hundreds of millions of dollars range. As promised, today I’ll be taking a look at ETFs that started the year with larger asset bases—at least $100 million. Naturally, the percentage growth for these funds is smaller, but still massive. For instance, the [**BNY Mellon US Large Cap Core Equity ETF (BKLC)**](https://www.etf.com/BKLC), the first “true” zero-fee ETF, has gathered $1.3 billion in inflows so far in 2023, a big haul for a fund that started the year with only $429 million in AUM. As I wrote [earlier this month](https://www.etf.com/sections/features-and-news/zero-fee-etf-crosses-1b-aum-first-time), BKLC’s inflows suggest that investors are finally taking notice of a fund that undercuts the already ultra-cheap ETFs that dominate the large cap equity segment. **Bargain Hunting** Following behind BKLC are two natural-gas focused ETFs, the [**ProShares Ultra Bloomberg Natural Gas (BOIL)**](https://www.etf.com/boil) and the [**United States Natural Gas Fund (UNG)**](https://www.etf.com/ung), with inflows of more than $1.1 billion each. It’s not hard to see why investors are plowing their money into this pair of ETFs. Natural gas prices have been cut in half since the start of the year. This looks like a clear case of bargain hunters seeking a bounce in a beaten-down commodity. Further down the list, the [**AXS Short Innovation ETF (SARK)**](https://www.etf.com/SARK) is another standout. A big story this year has been the recovery in growth stocks, with the most beaten-down stocks of 2022 leading the way. The [**ARK Innovation ETF (ARKK)**](https://www.etf.com/ARKK), which holds many of those stocks, has benefited, leading to a 27% year-to-date gain for the fund. Clearly, some investors don’t see this as a sustainable move. SARK, which bets against ARKK, has collected just over $300 million of inflows this year, more than double the $258 million in AUM it started 2023 with. Investors buying up the [**Direxion Daily Semiconductors Bear 3x Shares (SOXS)**](https://www.etf.com/soxs) probably have a similar thesis as investors in SARK. The fund provides triple-leveraged, inverse exposure to the index that underlies the [**iShares Semiconductor ETF (SOXX)**](https://www.etf.com/SOXX), which is up 19% so far this year. Year-to-date inflows of $1.3 billion for the fund compares to assets of $1.1 billion at the start of the year. **Fastest Growing ETFs of 2023 (Starting AUM >$100M)** TickerFundYTD 2023 Inflows ($M)Assets 12/31/22 ($M)Inflows %[BKLC](https://www.etf.com/BKLC)[BNY Mellon US Large Cap Core Equity ETF](https://www.etf.com/BKLC)1261429294%[BOIL](https://www.etf.com/BOIL)[ProShares Ultra Bloomberg Natural Gas](https://www.etf.com/BOIL)1583586270%[UNG](https://www.etf.com/UNG)[United States Natural Gas Fund LP](https://www.etf.com/UNG)1103429257%[BKIE](https://www.etf.com/BKIE)[BNY Mellon International Equity ETF](https://www.etf.com/BKIE)283146194%[BBEU](https://www.etf.com/BBEU)[JPMorgan BetaBuilders Europe ETF](https://www.etf.com/BBEU)54763153174%[PFEB](https://www.etf.com/PFEB)[Innovator U.S. Equity Power Buffer ETF - February](https://www.etf.com/PFEB)326228143%[FLKR](https://www.etf.com/FLKR)[Franklin FTSE South Korea ETF](https://www.etf.com/FLKR)156124125%[SARK](https://www.etf.com/SARK)[AXS Short Innovation ETF](https://www.etf.com/SARK)301258117%[SOXS](https://www.etf.com/SOXS)[Direxion Daily Semiconductors Bear 3x Shares](https://www.etf.com/SOXS)12921131114%[FXO](https://www.etf.com/FXO)[First Trust Financial AlphaDEX Fund](https://www.etf.com/FXO)1048111494%[JVAL](https://www.etf.com/JVAL)[JPMorgan US Value Factor ETF](https://www.etf.com/JVAL)36842487%[DIVI](https://www.etf.com/DIVI)[Franklin International Core Dividend Tilt Index ETF](https://www.etf.com/DIVI)8611277%[SQQQ](https://www.etf.com/SQQQ)[ProShares UltraPro Short QQQ](https://www.etf.com/SQQQ)2986430469%[IBDW](https://www.etf.com/IBDW)[iShares iBonds Dec 2031 Term Corporate ETF](https://www.etf.com/IBDW)10515468%[RFV](https://www.etf.com/RFV)[Invesco S&P MidCap 400 Pure Value ETF](https://www.etf.com/RFV)12318367%[PJAN](https://www.etf.com/PJAN)[Innovator U.S. Equity Power Buffer ETF - January](https://www.etf.com/PJAN)25938867%[XES](https://www.etf.com/XES)[SPDR S&P Oil & Gas Equipment & Services ETF](https://www.etf.com/XES)20231265%[FEMS](https://www.etf.com/FEMS)[First Trust Emerging Markets Small Cap AlphaDEX Fund](https://www.etf.com/FEMS)10516763%[FNGD](https://www.etf.com/FNGD)[MicroSectors FANG+ Index -3X Inverse Leveraged ETNs due January 8 2038](https://www.etf.com/FNGD)9014861%[JEPQ](https://www.etf.com/JEPQ)[JPMorgan Nasdaq Equity Premium Income ETF](https://www.etf.com/JEPQ)577100457%*Email Sumit Roy at or follow him on Twitter [sumitroy2](https://www.etf.com/sumitroy2)* [ + Follow ](/etf/login) [ Sumit Roy Senior ETF Analyst ](/authors/sumit-roy) Sumit Roy is the senior ETF analyst for etf.com and author of (Don't) Invest Like a Pro.
