Memory Leads the New Wave: Three Semiconductor Giants Positioned to Dominate the AI Cycle

Paradigm Shift: Why Memory Is Now Leading the Game

The technological landscape is undergoing a fundamental transformation. While recently central processing units (CPUs) captured all the attention of investors and analysts, the true growth driver in artificial intelligence has shifted to a less visible but equally critical area: data storage and memory management.

According to Gil Luria of DA Davidson, “Modern AI systems face an unprecedented memory bottleneck. The exponential leap in model sophistication has generated an unmatched demand for storage capabilities. Servers, data centers, and entire infrastructures require more powerful and versatile memory solutions than ever before.”

This evolution explains why companies specializing in memory semiconductors are experiencing increasingly attractive valuations for market participants. Unlike Nvidia’s closed ecosystem, the memory market is fragmented and accessible to multiple global players.

Three Key Names to Capitalize on the Hardware Revolution

Micron: From Cyclical Lag to Strategic Infrastructure

The Idaho-based company has radically transformed its narrative over the past twelve months. Its valuations have appreciated by nearly 240%, leaving behind the perception of being a secondary component in the tech cycle. Most notably, even with this expansion, Micron trades at just 9.9 times its projected earnings, a fraction of the 22 times the S&P 500 index trades at or the 25 times that Nvidia commands in the market.

The growth engine lies in high-bandwidth memory (HBM), specialized and differentiated technology that is indispensable for training next-generation AI models. Micron projects that the HBM segment could reach a valuation of $100 billion by 2028, with annual growth rates of 40%. This scenario makes the company a direct beneficiary of the memory supercycle just beginning.

SK Hynix: The Threatened Supremacy of the South Korean Market

While Micron is generally the preferred choice among Western investors, many analysts recognize that SK Hynix represents the true heart of the memory revolution. This South Korean company dominates its relationship with Nvidia, controlling approximately 60% of the HBM market by the end of 2025.

However, this dominant position is under pressure. The production bottleneck is real: SK Hynix faces severe restrictions in its manufacturing capacity that could hinder its ability to scale to the new HBM4 generations. If the company fails to expand its production in time, 2026 could bring a significant redistribution of market share toward alternative competitors.

But UBS analysts offer a different perspective: they project that SK Hynix could strengthen its position to 70% of the HBM4 market in 2026, especially if it manages to be Nvidia’s preferred supplier for the upcoming Rubin platform. The outcome will depend on resolving that critical capacity bottleneck.

SanDisk: The Surprising Winner of 2025

SanDisk emerged as the least expected player of the year. After its spin-off from Western Digital, its shares surged over 800%, catapulting the company into the center of hardware discussions.

Although DRAM (volatile memory) dominates headlines about AI, SanDisk controls an equally important vertical: NAND flash technology for long-term storage. This segment is gaining exponential relevance in what Luria calls “edge AI”—decentralized innovations like autonomous vehicles and robotic systems that require local data processing and storage, without relying solely on central servers.

Warnings Investors Should Not Ignore

Despite prevailing optimism, Luria introduces a note of caution that warrants serious consideration: memory semiconductors remain fundamentally commodity products with commoditized features.

Unlike Nvidia, whose proprietary software creates lasting barriers to differentiation, memory products are largely interchangeable among providers. This means that once current supply bottlenecks are resolved, pricing power will be significantly eroded.

“Nvidia could concentrate its orders with SK Hynix this fiscal year and switch entirely to Micron the next,” Luria exemplified. This opportunistic behavior reduces the predictability and long-term stability of revenues for these memory suppliers.

Currently, investors are making a tactical bet: emphasizing immediate bottlenecks over long-term structural risks. “In acute shortages, trading and investment decisions are driven by short-term dynamics, temporarily dismissing the vulnerabilities that will emerge later,” Luria concluded.

This is a moment of opportunity, but not of complacency.
