SK Hynix’s US stock pricing imminent, top AI funds scrambling to buy, UBS expects long-term “inflows” of $15 billion

SK Hynix's issuance of American Depositary Receipts (ADRs) in the US has entered a crucial pricing period. The intensive buying by top AI funds and expectations of massive passive capital inflows are reshaping the valuation logic of this memory chip giant and giving rise to complex cross-market arbitrage trades.

The latest disclosed list of Base offering subscribers shows that renowned AI funds such as BG, Coatue, and Situational Awareness have all entered the game. The incremental capital expectations are even larger. According to UBS calculations, in the long term, SK Hynix's ADR inclusion in core semiconductor indices could attract up to $15 billion in passive funds. With expectations of capital inflows, cross-market arbitrage strategies involving going long ADRs and shorting Korean stocks have started to emerge.

These capital operations not only confirm institutions' consensus on the high prosperity of the AI semiconductor sector, but also mean that, with the gradual exhaustion of cross-market conversion quotas, SK Hynix's pricing power and premium space in the US stock market will undergo substantial revaluation.

Top AI Funds Gather, Pricing Schedule Clarified

The institutional subscription details for SK Hynix's ADR issuance reveal Wall Street's enthusiasm for allocating to the foundations of AI computing power. The Base offering subscriber list brings together renowned AI funds such as BG, Coatue, and Situational Awareness (founded by former OpenAI employees), showing a strong consensus among leading technology investment institutions for the AI semiconductor sector.

The pricing schedule is now fully clarified. The final issue price will be set on July 9, new shares will be issued on the Korea Exchange on July 10, and funds will be received on T+1.

Due to recent stock price fluctuations and institutional games, the current recommended issue price has been lowered compared to earlier periods. This adjustment objectively reflects the recent pullback in the secondary market and provides participating institutions with a better margin of safety and pricing benefit.

Index Inclusion Expectations: A Short-term Feast of $3.5 Billion and a Long-term $15 Billion

The most direct boost to SK Hynix's ADR issuance comes from the forced allocation by passive funds. UBS's latest research report provides detailed calculations of capital inflows after the ADR is included in various indices.

From an index fund perspective, SK Hynix, with a circulating market value of about $96 billion after listing, is expected to be included in the MVIS US Semiconductor 25 Index. Due to the maximum weight rules for constituent stocks, SK Hynix could have up to a 5% weight in this index. The SMH semiconductor ETF tracking this index alone will bring about $3.5 billion in passive fund inflows. In comparison, if included in the SOXX index, its weight would only be 0.5%, corresponding to about $200 million in inflows.

In the long run, as the ADR's float expands, SK Hynix may be included in the Nasdaq 100 Index. UBS expects a combined long-term inflow of about $15 billion in passive funds. However, the company is unlikely to be included in the S&P Technology Select Index in the short term.

Cross-Market Arbitrage Emerges: Betting on Quota Exhaustion and ADR Premium

As the ADR issuance progresses, the cross-market conversion quota between Korean and US stocks has become the core variable in arbitrage funds' games. The market estimates the maximum conversion quota for Korean stocks to US ADRs to be 15% or 20%, corresponding to a total convertible stock market value of nearly $200 billion.

Currently, the market has begun to construct cross-market arbitrage trades involving going long US ADRs and shorting Korean stocks. The core logic of this strategy is to bet that, after the conversion quota is exhausted, overseas capital can only buy ADRs directly in the US, thus forming a long-term ADR premium over Korean stocks. As a reference, TSMC's ADR had an average premium of up to 16% versus Taiwan stocks in June 2026.

Although most views believe that quota exhaustion will be a lengthy process, a difference in market expectations is forming.

With the memory chip industry highly prosperous, the pace of overseas capital entry may far exceed expectations. The future scale of cross-market conversion of existing stocks will directly change SK Hynix’s weight in US stock ETFs. The pace of quota exhaustion and the timing of premium manifestation may come sooner than the market expects.
