Memory chips drive record profits for Samsung, SK hynix and Micron

The global semiconductor market has reached a historic turning point as the top five memory chip suppliers recorded higher combined operating and net profits than the top five American tech giants for the very first time. This unprecedented financial surge was driven by the ongoing artificial intelligence boom, where surging demand for specialized memory continues to significantly outpace available production capacity.

• Combined quarterly operating profit for the top five memory chip makers reached approximately 32 trillion yen ($204 billion).
• By comparison, the combined operating profit of Alphabet, Microsoft, Amazon, Meta, and Apple totaled 25 trillion yen.
• Operating profit margins for memory manufacturers jumped from around 10% in the first half of 2025 to nearly 70%.
• Memory chip prices have multiplied tenfold over the past year and a half.

Financial milestones across the memory sector

According to data from QUICK FactSet, the leading group of memory manufacturers includes Japan's Kioxia Holdings, South Korea's Samsung Electronics and SK hynix, alongside US-based Micron Technology and SanDisk. Together, these five companies control the overwhelming majority of the global memory market. Individual results have been staggering; for instance, Kioxia reported a 23-fold increase in operating profit, while its net profit skyrocketed 33 times to exceed 1 trillion yen.

Meanwhile, South Korean giant Samsung Electronics reported an operating profit of nearly 107 trillion won ($80.2 billion), marking an almost ninefold increase year-over-year. The company officially highlighted its status as the world's first technology corporation to cross the 100 trillion won quarterly operating profit threshold. Furthermore, Samsung has already completely sold out its entire scheduled production volume of high-bandwidth memory (HBM) for the upcoming year.

Driven by surging tech infrastructure investments

The immense profitability of memory makers is directly tied to the capital expenditures of American technology giants. With the exception of Apple, major players like Microsoft, Alphabet, and Amazon continue pouring enormous investments into expanding data center infrastructure to support heavy AI workloads. These massive infrastructure deployments deplete available memory supply, creating shortages and yielding massive profit margins for hardware vendors.

Industry analysts note that this dynamic has fundamentally shifted the traditional balance of power within the technology sector. While software developers and cloud platform operators traditionally captured the majority of value in the digital economy, silicon hardware manufacturers are now reaping the largest financial rewards from the infrastructure layer.

What this means for the tech industry

The explosive revenue growth among memory suppliers underscores the rapid integration of artificial intelligence hardware into enterprise infrastructure. However, soaring component costs are raising questions regarding the long-term sustainability of such aggressive capital expenditure levels. If component prices remain elevated, technology enterprises may eventually be forced to recalibrate their infrastructure budgets, potentially impacting the cost of AI services worldwide.
