Sandisk (SNDK) Surges 13% on Memory Price Hikes and AI Demand Surge: What’s Fueling This Record High?

Summary
• Sandisk (SNDK) rockets 13% to $166.06, hitting a 52-week high of $167.22
• Intraday range spans $146.00 to $167.22, with $6.8 million turnover
• South Korean memory price hikes and AI-driven demand cited as key catalysts

Today’s explosive move in Sandisk shares has sent ripples through the storage sector, with the stock surging to a record high amid reports of aggressive price increases by South Korean memory giants. The rally coincides with heightened demand for NAND flash tied to AI infrastructure, positioning Sandisk at the center of a sector-wide surge. With technical indicators flashing bullish signals and options activity intensifying, investors are scrambling to decode the next chapter in this high-octane trade.

Memory Price Hikes and AI Demand Fuel Sandisk's Record High
Sandisk’s 13% surge to $166.06 is directly tied to reports of South Korean manufacturers Samsung and SK Hynix hiking memory prices by up to 30% for Q4 2025. This follows a surge in demand for NAND flash and DRAM driven by AI infrastructure expansion, particularly in cloud computing and enterprise storage. Analysts highlight that Sandisk’s strategic partnerships with cloud providers and its role in the Kioxia joint venture position it to capitalize on this trend. Additionally, recent upgrades to Sandisk’s SSD technology and its vertical integration model have bolstered investor confidence in its ability to sustain margins amid rising component costs.

Storage Sector Rally Led by Memory Price Hikes and AI-Driven Demand
The broader storage sector mirrored Sandisk’s gains, with Western Digital (WDC) and Seagate (STX) rising over 3% on the same day. However, Sandisk’s 13% surge outpaced peers, reflecting its stronger ties to AI-driven NAND demand and recent technological advancements. The sector’s momentum is underpinned by Phison’s confirmation that recent Windows 11 update concerns were unfounded, removing a key overhang. Meanwhile, Kioxia’s LC9 Series 245TB SSDs and Micron’s Gen6 SSDs highlight the industry’s focus on high-capacity solutions for AI workloads, aligning with Sandisk’s strategic direction.
