A 7x oversubscription for a $26.5B listing is an absolute monster of a debut. While the "peak sentiment" bears will naturally argue that this is a valuation top, the underlying fundamentals of the High Bandwidth Memory (HBM) market suggest we are looking at a genuine structural shift rather than a temporary bubble.
A few reasons why this leans more toward a super-cycle than peak euphoria:
Insatiable AI Demand: Next-gen AI chips (like NVIDIA's Blackwell and beyond) require exponentially more HBM. As the clear market leader in HBM3e, SK Hynix isn't just riding a wave; they are building the infrastructure for it.
Supply is Already Locked In: Major memory producers have already noted that their HBM capacity is fully booked out through the foreseeable future. When supply cannot keep up with secular demand, prices stay sticky-high.
