New AI Phase Reshapes Chipmakers' Business Models

US stock markets remain near record levels in the second half of the year, with artificial intelligence emerging as the primary driver of long-term growth. While investors monitor geopolitical tensions, trade deals, and central bank decisions, recent earnings reports confirm that AI is fueling the expansion of capital markets.

The growth of major tech companies is increasingly supported by rising revenues, profits, and optimistic guidance from leadership, moving beyond investor expectations alone. AI is transitioning from a development project to a major investment narrative in the modern economy.

Semiconductor and memory chip manufacturers have garnered significant attention. Nvidia, Broadcom, Micron, SK Hynix, and Samsung have all reported exceptional demand for AI infrastructure. More importantly, their leadership's forecasts indicate no slowdown in the investment cycle. Major AI users, including Microsoft, Meta, Amazon, and Alphabet, are also increasing capital expenditures for data centers, developing proprietary AI models, and acquiring advanced chips and computing equipment.

The fact that these tech giants continue to raise their capital expenditure plans despite record investments signals that AI development is still in the early phase of a multi-year investment cycle. This sustained investment underscores the transformative potential and ongoing expansion of AI technologies across various sectors.

A particularly noteworthy development comes from Micron, a leading memory chip producer for AI systems. While Nvidia symbolizes AI advancement, Micron illustrates a profound change in the business model across the entire supply chain. The company has secured sixteen multi-year strategic agreements with major clients, involving over $22 billion in deposits and at least $100 billion in contracted revenue. Notably, these contracts guarantee production capacity rather than fixed prices. This contrasts with previous years when memory chip manufacturers competed primarily on price. Now, major AI service providers compete for timely delivery. This collaborative approach enhances business visibility and marks a significant evolution for an industry historically known for its cyclical nature. Korean firms SK Hynix and Samsung echo this trend, projecting that demand for high-performance memory chips will significantly outstrip supply even beyond 2027 due to robust order growth, lengthy construction of new production facilities, complex technological processes, and a limited supply of skilled labor.
