On June 15, Rambus rose 5.12% overnight, trading at $153.79/share, with turnover of $148,600. The rally extends the stock's recovery trend from lows near $120, driven by broad semiconductor sector strength and sustained optimism around AI-related storage demand.

On the news front, the semiconductor sector rallied broadly, with Advanced Micro Devices up 5.31%, Marvell Technology up 5.19%, Micron Technology up 5.09%, and Intel up 4.9%. The sector continues to benefit from elevated AI demand sentiment. Earlier this month, NVIDIA announced a multi-year technology partnership with SK Hynix to co-develop next-generation AI memory, while CEO Jensen Huang stated that storage supply shortages will persist for years across the entire supply chain from wafers to packaging. UBS projects global semiconductor revenue to reach $1.62 trillion in 2026, with memory chip revenue alone growing 318% to $961 billion, underpinned by HBM and DDR5 demand from Agentic AI applications.

Rambus had previously pulled back due to insider selling exceeding $9 million and sector-wide pressure. The current rebound reflects renewed confidence in the long-term structural demand for high-bandwidth memory and AI-related storage solutions.
