Ajinomoto Soars 56% in 2026 as ABF Price Hike Drives Record AI Chip Profits

- 30% ABF price jump delivers record profits and fuels 56% stock surge amid critical supply shortages - Supply-demand gap projected to reach 42% by 2028, escalating costs for top chipmakers and cloud giants On July 22, 2026 (UTC), CNBC reported that Ajinomoto, best known for MSG, has cemented itself as a pivotal force in the global artificial intelligence hardware market by leveraging its commanding 95%+ market share of Ajinomoto Build-up Film (ABF). ABF is an essential insulating material for advanced AI chip packaging, and demand for ABF is skyrocketing as the semiconductor and cloud computing industries race to expand data infrastructure for next-generation applications. Earlier in 2026, Ajinomoto raised ABF prices by 30%, and this move propelled quarterly profits up by 127% and pushed its full-year business outlook sharply higher. As a result, the combination of surging demand and higher prices fueled a 56% jump in Ajinomoto’s stock since the start of the year, underscoring the company’s strategic dominance as supply pressures mount. On July 22, 2026, CNBC further reported that persistent ABF shortages and increasing chip substrate complexity now pose major challenges for industry leaders like Nvidia, Intel, AMD, Microsoft, Google, and Amazon. According to the same CNBC report, Ajinomoto’s price hike has inflated chipmakers’ substrate expenses by an estimated 3–6%, and these costs are rapidly flowing through to hyperscale cloud operators. Meanwhile, data from TradingKey on June 1, 2026, indicated that the global ABF supply-demand gap already stands at 10%, and BigGo Finance reported on May 8, 2026, that this gap is expected to surge to 42% by 2028. TradingKey also noted that Ajinomoto plans to invest over 25 billion yen (about $150 million) to boost ABF production by 50% by 2030, while BigGo Finance added that a new plant will not begin operations until at least 2032, prolonging supply risks for years to come. In addition, industry analysis from TrendForce reported that, in response to tightening supply, leading semiconductor and cloud players are advancing prepayments and locking in long-term ABF contracts to guarantee access. This supply squeeze is already affecting profitability, project delivery, and capital planning throughout the chip and cloud sectors, and TrendForce emphasized that Ajinomoto’s overwhelming ABF market share and assertive pricing are forcing technology leaders to reassess sourcing strategies, margins, and AI infrastructure scaling plans. On July 22, 2026, CNBC also reported that Ajinomoto’s stock has climbed as much as 65% in 2026, highlighting its expanded power and growing influence throughout the AI hardware supply chain, even as customers confront growing sourcing challenges and financial pressures. Furthermore, data from CNBC, BigGo Finance, TradingKey, and TrendForce indicate that ABF shortages and price hikes are likely to persist through the decade, with broad implications for industry costs and infrastructure investments worldwide.
