Intel and SK hynix shares surge on chip packaging partnership rumors

Shares of Intel and SK hynix surged following reports that the South Korean memory maker is testing Intel's 2.5D EMIB technology for High-Bandwidth Memory integration. The market reaction was immediate and significant, with SK hynix stock climbing 14.5 percent to an all-time intraday high of $1,320. This move pushed the company's market capitalization past $900 billion. Intel shares also rose nearly 14 percent, marking a 229 percent gain over the last six months and a 91 percent increase in the last month alone.

Stock prices jump on reports of advanced packaging collaboration between two major semiconductor vendors

The core of the speculation involves SK hynix evaluating Intel's Embedded Multi-die Interconnect Bridge for use in next-generation HBM modules. This technology aims to provide a cost-effective alternative to TSMC's CoWoS packaging, which currently faces capacity constraints. Industry analysis suggests that Nvidia alone accounts for roughly 60 percent of global CoWoS demand this year. Intel's foundry division is actively marketing both EMIB and EMIB-T technologies to external customers to capture this growing market share.

Both companies are heavily investing in physical infrastructure to support advanced packaging capabilities. SK hynix recently broke ground on a $3.87 billion advanced packaging plant in Indiana. Simultaneously, the company approved a 19 trillion won facility, valued at approximately $12.9 billion, for packaging and testing in South Korea. Intel CFO Dave Zinsner stated in March that the foundry division is close to closing deals that will generate billions in annual revenue, signaling strong commercial momentum for these packaging solutions.

Reports regarding the potential partnership originate from ZDNet Korea and cite unnamed industry sources. Neither Intel nor SK hynix has officially confirmed the testing activities or the nature of any potential collaboration. The market's positive response highlights the intense competition for advanced chip packaging resources in the AI hardware sector. Investors appear to be betting on the viability of alternative packaging architectures as demand for high-performance memory continues to outpace supply.
