In 2026, the wave of artificial intelligence infrastructure buildout is reshaping the global semiconductor landscape at an unprecedented pace. Within the NAND flash memory market, an AI-driven supply-demand imbalance is creating a new industry legend — SanDisk (SNDK) shares have already surged 7x year-to-date, pushing its market capitalization past $290 billion. And the latest industry forecasts suggest this may be merely the opening chapter of its journey toward a trillion-dollar valuation.
Supply-Demand Imbalance: The Golden Era of the NAND Flash Market
AI infrastructure has emerged as the most powerful engine driving NAND flash demand. Compared to traditional hard disk drives (HDDs), solid-state drives (SSDs) offer faster access speeds and greater power efficiency, making them ideal for storing the massive datasets required for AI training and inference. At the same time, the high cost and limited supply of high-bandwidth memory (HBM) have further underscored the strategic value of NAND flash.
Market research firm TrendForce has sharply revised its memory market forecasts upward in its latest report: the global NAND flash market is expected to reach $270.6 billion in 2026, a staggering 280.7% year-over-year surge, and is projected to expand further to nearly $379.4 billion in 2027, maintaining roughly 40% annual growth. The core logic driving this growth lies in AI’s shifting focus from large-scale model training to inference-centric agentic AI applications — which frequently access massive vector databases during task execution, generating exponential growth in storage demand.
More critically, the supply side cannot respond in the near term. TrendForce notes that major NAND manufacturers have virtually no new capacity additions in 2026, with supply shortages expected to persist throughout the year. Gartner projects NAND flash prices will rise 234% this year, with no meaningful relief until late 2027. SanDisk CEO David Goeckeler has revealed that the company’s 2026 capacity is completely sold out, and 2027 capacity is already facing strong early-booking demand.
The Multiplier Effect of a 13% Market Share
According to Counterpoint Research, SanDisk held a 13% share of the global NAND flash market in the first quarter of 2026. Should that share remain stable through the end of 2027, and based on TrendForce’s forecast of $379.4 billion in total industry revenue, SanDisk’s calendar 2027 revenue could reach $49.3 billion — a multiple increase from its current trailing-twelve-month revenue of approximately $13.2 billion.
On the valuation front, SanDisk currently trades at a price-to-sales ratio of roughly 26x, well above the U.S. tech sector’s average multiple of 8x. However, this reflects its high-growth profile — its most recent quarterly net profit margin has exceeded 60%. Even if its P/S ratio moderates to around 20x by the end of 2027, combined with nearly $50 billion in annual revenue, a trillion-dollar market cap is far from out of reach.
The Road to a Trillion Is Not Without Bumps
Of course, achieving this forecast still faces numerous uncertainties. The NAND flash market has long been characterized by strong cyclicality — capacity expansion timelines, macroeconomic fluctuations, and technology roadmap shifts could all alter the existing supply-demand dynamics. However, given the observable certainty of AI infrastructure investment trends, SanDisk sits at the very core of this industrial transformation.
For investors bullish on the long-term prospects of AI infrastructure, this memory leader — at its current $290 billion market cap — may still offer considerable upside potential.
