Europe's artificial intelligence story is entering a new phase, one defined less by who builds the infrastructure and more by who deploys it productively, and that shift could finally put the continent at the centre of a debate from which it has largely been excluded.
That is the central argument of an 81-page report from Citi, coordinating analysis from economists, equity strategists and more than twenty sector analysts to assess the state of AI adoption across European markets and identify the companies best placed to benefit.
The economics offer a sobering starting point. The OECD estimates AI-related investment across the European Union reached around €257 billion in 2023, equivalent to 1.2% of the bloc's GDP.
That sounds substantial until you note that the United States was spending approximately 2.5 times as much in absolute terms, and twice as much as a proportion of GDP, in the same year.
Labour productivity across the eurozone has declined sharply over the past three years, and even in the sectors most likely to benefit early from AI, there is no detectable acceleration.
Citi's economists are careful not to overstate the pessimism. The internet's productivity benefits took roughly three years to become visible in the data after the initial surge in related investment.
If the same pattern holds, then the rapid rise in AI investment since late 2022 points to a productivity pickup beginning soon.
Against that uncertain backdrop, the equity analysis is more actionable. Semiconductor equipment makers ASML, ASM International, VAT Group and Infineon are identified as core holdings regardless of how the broader AI debate evolves.
Among industrials, Schneider Electric, Siemens, ABB and Prysmian offer exposure to data centre construction and power infrastructure. In banks, Lloyds, HSBC, BNP Paribas and NatWest are delivering quantifiable AI-driven cost and revenue benefits at scale.
The report's most persistent caution, however, is that AI will not be a uniform tailwind.
Competition, regulatory pressure and customer bargaining power will absorb much of the efficiency savings before it reaches the bottom line in sectors with limited pricing power, including autos, chemicals and airlines.
