"Double Hynix" has become the global leader; the global leveraged/inverse "single-stock ETF" scale has doubled in one and a half months.

```

The global single-stock leveraged ETF market is undergoing an unprecedented expansion, with AI and memory chip themes serving as the core driving forces of this frenzy.

According to the latest tracking data by Chris Lucas, a top trader at Goldman Sachs, the global leveraged/inverse single-stock ETF assets under management have surpassed $60 billion and have doubled since early April, a speed of growth that has attracted market attention. Amid this wave, an ETF offering 2x long exposure to SK Hynix has become the world's largest leveraged single-stock ETF, reflecting investors’ highly concentrated bets on the global AI and memory chip themes.

The Goldman Sachs team has not made a clear directional judgment about this exponential demand, but at the same time pointed out that there are multiple potential catalysts that could trigger "chaotic liquidations." A seasoned trader stated bluntly: "This won't end well... but for some traders, getting out early could itself be fatal."

Doubling in size in a month and a half—US, Hong Kong, Korea in a three-way rivalry

Since the United States launched single-stock ETF products in 2022, the size and coverage of this market have continuously expanded, with a particularly noticeable recent acceleration.

According to Bloomberg and Goldman Sachs Global Fixed Income and Equity Division data as of May 27, 2026, the total global leveraged/inverse single-stock ETF size has exceeded $60 billion, doubling in about a month and a half compared to the less than $30 billion level in early April.

In terms of distribution, the US market occupies about 70% share, totaling around $46 billion; Hong Kong ranks second with about $13 billion and net inflows of $10 billion in the past two months; Korea ranks third with about $3.3 billion, its first single-stock ETF products just completing their listing this week. These three nations currently constitute the main landscape of global single-stock leveraged ETFs.

"2x Hynix" tops the chart, AI memory themes dominate fund flows

The protagonists of this capital frenzy have quietly shifted from traditional US mega-cap tech stocks to targets in the global AI industry chain’s memory chip sector.

Currently, the world's largest leveraged single-stock ETF is a product offering 2x long exposure to SK Hynix (Hong Kong ticker: 7709 HK). Meanwhile, SK Hynix single-stock ETF (code: 0193T0 KS) and Samsung Electronics single-stock ETF (code: 0193W0 KS), newly listed in Korea this week, attracted around $1.2 billion and $816 million in inflows within just two days, an uncommon subscription heat.

Additionally, ETFs tracking the DRAM theme have become some of the fastest-growing ETF categories ever, further highlighting the market’s highly concentrated attention on the memory chip sector. Chris Lucas pointed out that investors are seeking leveraged exposure to core price-driving targets in the global AI complex, a trend that closely matches the explosive growth of the aforementioned products.

Goldman Sachs warns: "chaotic liquidation" risks lurk beneath exponential expansion

Despite the strong enthusiasm on the demand side, the Goldman Sachs team has issued cautious signals regarding this market structure.

Goldman Sachs stated that although it makes no directional judgment regarding the current exponential demand, it has clearly pointed out multiple potential catalysts that could trigger chaotic liquidations. Due to their structural characteristics, leveraged single-stock ETFs may cause concentrated, rapid forced selling during major fluctuations in underlying assets, which can amplify the effects on the underlying stock prices.

A seasoned trader expressed a noteworthy warning: "This won't end well... but for some traders, getting out early could itself be fatal." This sentence precisely describes the current dilemma faced by market participants—worried about systemic risks of a bubble burst, yet unable to bear the opportunity cost pressure of exiting too early. It is this game-theory psychology that objectively continues to push up the market’s concentration and fragility.
