The AI infrastructure buildout is revitalizing some of Europe’s biggest tech shares.
German chipmaker Infineon Technologies IFX, one of Europe’s largest semiconductor stocks, has been on a tear in 2026. Traditionally a key supplier for electric vehicles and energy systems, it is increasingly viewed as a critical AI play, driving data center development.
Infineon’s share price is up around 75% so far this year, lately cooling from an all-time high in June. Shares have now gained more in the past year than the prior five combined.
So, what is moving the stock in 2026?
Why is Infineon’s Stock On the Up?
Infineon has been gradually emerging from an industry-wide slump, with semiconductor inventories correcting following a pandemic-era boom.
Global revenues were up 6% annually in the fiscal second quarter. But, more importantly, the company raised its full-year earnings guidance. It now forecasts revenue to grow “significantly” year-on-year, amid stronger AI-related demand and a “broader upcycle.”
Morningstar senior equity analyst Brian Colello says Infineon has particularly benefited from the industry’s energy efficiency push, boosting demand for its specialist power semiconductors. Yet, like most chipmakers, Colello warns that the business remains “highly cyclical”: Its demand is contingent on the health of its various end markets, meaning potential volatility for the stock.
So, is Infineon stock a buy now?
Are Infineon Shares a Buy in 2026?
Infineon’s stock has pulled back around 25% since its June peak, getting caught in a broader sector selloff as investors weigh the outlook for AI.
Shares are now trading around EUR 67 a piece, still around a 22% premium to Morningstar’s fair value estimate of EUR 55. And while Colello is bullish on Infineon’s competitive advantage over the coming decade, he suggests investors may await a better entry point to come.
Infineon’s fiscal third quarter earnings in early August could provide the latest read.
