OpenAI CEO Sam Altman reportedly met with SK Group executives in South Korea to discuss HBM supply and Stargate AI infrastructure, and the market read that meeting as a strong signal for SK Hynix's near-term order book.
Customers are already requesting more than twice the HBM SK Hynix can actually ship, and that order pressure makes supply the binding constraint on how fast AI infrastructure projects like Stargate can scale.

For investors, the implication is that any confirmed deal coming out of Altman's Seoul visit would tighten an already strained supply chain further, putting SK Hynix in a position to dictate terms.
A move on a reported meeting, before any contract is announced, reflects how sensitive AI infrastructure stocks have become to signals about HBM allocation. If talks advance to a formal supply agreement, the reaction to the rumor alone suggests the market would reprice sharply again.
