SEOUL — Semiconductor manufacturers and suppliers are expanding production, raising capital and accelerating investment plans as sustained demand for artificial intelligence infrastructure continues to reshape the global chip industry, even as investors grow more cautious about the pace of returns from heavy AI spending.
The latest sign of the industry's expansion came on Monday, when South Korean memory-chip maker SK Hynix launched a roughly $28 billion U.S. share offering to finance new fabrication facilities and advanced manufacturing equipment. The company said the proceeds would support capacity growth aimed at meeting rising global demand for AI-related semiconductors, particularly high-bandwidth memory used in AI servers.
Across the sector, manufacturers are responding to continued investment by cloud computing providers and technology companies building AI data centers, driving demand for advanced processors, memory chips, packaging technologies and semiconductor manufacturing equipment.
Industry researchers have forecast another year of strong expansion. Gartner said worldwide semiconductor revenue is expected to exceed $1.3 trillion in 2026, supported by robust demand for AI processors, networking chips and memory products. Deloitte has likewise projected record industry sales this year, citing AI infrastructure as the principal driver of growth.
TrendForce said demand for advanced multilayer ceramic capacitors, a critical component in AI servers, has pushed order levels among major Japanese and South Korean suppliers to their highest since the COVID-19 pandemic, increasing the risk of supply constraints during the second half of 2026. The research firm also forecasts global foundry revenue to rise sharply this year as AI chip production expands.
Despite the industry's strong fundamentals, financial markets have become more volatile. Goldman Sachs said hedge funds reduced exposure to semiconductor stocks for a fourth consecutive week ahead of earnings season as investors assessed whether the substantial capital committed to AI infrastructure would translate into sustainable revenue growth. The Philadelphia Semiconductor Index declined during the latest trading week after a strong rally earlier in the year.
Analysts say the sector remains supported by long-term investment from hyperscale cloud providers, although supply-chain resilience, energy availability and geopolitical tensions continue to pose operational challenges. Industry executives surveyed by KPMG identified tariffs, trade policy and power availability among their leading concerns as companies expand manufacturing capacity worldwide.
The industry's next major focus will be quarterly earnings reports from leading chipmakers in the coming weeks, when investors will look for updated guidance on AI demand, production capacity and capital expenditure plans.
