European stock markets came under pressure on Tuesday as technology shares suffered their worst decline in months.

Investors have become increasingly concerned about the enormous sums companies are spending on artificial intelligence infrastructure and whether those investments will generate sufficient returns in the future.

The technology sector led losses across the continent, with several major semiconductor and chip-equipment manufacturers recording significant declines.

Companies involved in AI development and infrastructure have attracted huge investor attention over the past year, but some analysts now warn that expectations may have become overly optimistic.

Rising interest-rate expectations have added to investor caution. Higher borrowing costs can make it more difficult for companies to finance large expansion projects, especially those requiring substantial capital investment.

This has prompted a broader reassessment of some highly valued technology stocks.

The market decline also reflects growing debate about the long-term profitability of AI investments.

While many executives remain confident that artificial intelligence will transform industries, investors increasingly want evidence that massive spending plans will translate into stronger earnings.

Analysts believe the AI sector remains a long-term growth story, but they expect markets to become more selective as investors focus on companies capable of converting technological innovation into sustainable profits.
