SK Hynix reported a record second-quarter profit driven by surging demand for artificial intelligence memory chips, though the results fell short of market expectations, tempering an otherwise blistering earnings run.
The South Korean chipmaker said operating profit climbed sharply year over year, marking a fresh high for the company, while revenue more than tripled compared with the same period a year earlier. Net profit posted a roughly sixfold increase, underscoring the intensity of demand for its high-bandwidth memory products.
The strength stems largely from high-bandwidth memory, or HBM, a specialised type of chip stacked to deliver the rapid data transfer speeds required to train and run large AI models. SK Hynix has emerged as a leading supplier of these components, cementing a dominant position in a market that has expanded rapidly alongside the global build-out of AI infrastructure.
Despite the record figures, the results narrowly missed analyst forecasts, a gap that highlights how elevated expectations have become for firms tied to the AI boom. Investors have increasingly priced in extraordinary growth, leaving little room for even strong performances to satisfy the market.
The latest results extend a pattern seen in the company’s earlier reporting periods, when robust demand for AI memory delivered a run of standout quarters. SK Hynix’s earlier record quarterly profit tied to AI memory demand signalled the beginning of a sustained upswing that has continued to accelerate.
The performance stands in contrast to that of domestic rival and memory heavyweight Samsung Electronics, which has faced pressure in parts of its chip business amid uneven demand and pricing dynamics across the broader semiconductor market.
Memory chipmakers have benefited from a wave of capital spending by cloud providers and technology firms racing to expand data-centre capacity. That spending has fuelled orders for advanced memory, tightening supply and supporting prices for premium products.
This development comes as the industry navigates questions over how long the current cycle of AI-driven demand can sustain such elevated growth rates, and whether supply expansions could eventually ease the pricing environment.
SK Hynix is expected to continue prioritising output of its most advanced memory products as it works to meet commitments to major customers. The company’s trajectory in the coming quarters is likely to serve as a closely watched barometer for the health of the wider AI hardware supply chain.
