Intel to invest €5bn upgrading Irish chip plant for AI servers

Intel is spending €5bn to upgrade its Leixlip campus outside Dublin to produce advanced server chips for artificial intelligence infrastructure. The investment, announced on Monday, will not build a new fabrication plant but instead maximise the output of existing facilities.

The project involves installing leading-edge equipment and connecting separate cleanrooms into a single automated production line. The goal is to print Intel 3 silicon, specifically Xeon 6 processors and their successors, which Intel markets as the engines for AI data centres. “The demand for servers, the demand for AI is driving a significant increase in the need for Intel 3 wafers,” said Naga Chandrasekaran, executive vice-president of Intel Foundry.

For Intel, retooling qualified cleanrooms in Ireland is significantly faster than building a new plant from scratch, a lesson learned from ongoing delays at its Magdeburg site in Germany. The upgrade will consume roughly 30% of Intel’s planned $17bn capital expenditure for 2026, with the bulk spent by the end of 2027. It targets current, shippable technology rather than the company's most advanced 18A node, which remains centred in the United States.

This pragmatic focus on proven capacity arrives as Intel's financial position stabilises, following first-quarter revenue of $13.6bn and reported foundry interest from Apple. “This €5 billion investment represents a definitive commitment to maximize capacity at our Leixlip campus and increase what we can deliver to Intel Foundry customers,” Chandrasekaran said.

Intel explicitly framed the move as a contribution to European tech-sovereignty, a narrative that resonates in Brussels. The company has now invested more than €30bn in Ireland since 1989. The Leixlip campus currently employs 4,900 people, a figure that will grow by "several hundred" permanent roles alongside construction trades.

Taoiseach Micheál Martin called the spending “a powerful vote of confidence in Ireland, our skills base and our position at the heart of Europe’s most advanced manufacturing ecosystem”. That political enthusiasm reflects a structural vulnerability. Foreign-owned firms now account for roughly 11% of the Irish labour market, having nearly doubled their workforce over the past decade. In an economy of Ireland's size, a single 4,900-person manufacturing site is too large to be a rounding error, making Intel's ongoing commitment a matter of national economic significance.
