The AI Chip Cycle Is Creating a Surprising Money-Making Opportunity Through Korean Markets

[AIcash]

One of the most interesting asymmetric opportunities emerging from the AI infrastructure buildout is not in US tech stocks or crypto directly — it is in the Korean equity market, and specifically in EWY, the iShares MSCI South Korea ETF. EWY returned more than 37% in the first quarter of 2026 alone, driven primarily by Samsung Electronics and SK Hynix, which together make up roughly 45% of the fund's holdings. Both companies dominate global supply of high-bandwidth memory chips — the specific chip variant required for AI training systems — meaning every major data center expansion by Google, Microsoft, Amazon, and Meta flows directly into their order books. Options traders have taken notice in a significant way: call open interest on EWY has climbed to approximately $5.5 billion in notional value, the highest level ever recorded and well above previous peaks seen in 2015 and 2021. That level of call positioning reflects large players making leveraged bets on further upside, not retail speculation.

What makes this trade intellectually compelling is that it is effectively a leveraged AI infrastructure bet accessed through a less crowded door. US AI stocks like Nvidia are widely owned and heavily analyzed, with valuations that already price in significant growth. EWY, by contrast, offers concentrated exposure to the same AI capex cycle through the memory chip supply chain — a part of the stack that is just as essential but has historically attracted less mainstream investor attention. The macro read-through extends even further: Regional Greenhouse Gas Initiative carbon allowances in the Northeastern US rose 31% in a single week to a four-year high of $47 per metric ton, driven by power demand from AI data centers — the same demand inflating Samsung's order book and driving EWY's rally. Q2 earnings from Samsung and SK Hynix will be one of the clearest near-term signals of whether the AI memory cycle has further room to run, making those results a key date for anyone holding or considering EWY exposure.

Nvidia is crowded so serious investors bought a South Korean ETF instead, the alternative AI trade is very alternative
