Europe’s Best-Performing Stocks of 2026 — Including One Up 947%
European stock markets have had an unstable start to 2026. The Euro STOXX 600 index has gained around 3.5% this year, while the US S&P 500 has risen about 8%. However, some European companies have delivered much stronger results, with several stocks jumping by more than 100%.
Many of these gains have been driven by the rapid growth of artificial intelligence (AI), rising geopolitical tensions in the Middle East, increased spending on defence and energy infrastructure, and strong investor interest in new technologies.
Here is a simple look at some of Europe’s best-performing companies in 2026, what they do, and why investors are buying their shares.
Technology Companies Lead the Market
The biggest winner in Europe this year is Swedish company Sivers Semiconductors. Its share price has surged by 947% in 2026.
The company makes semiconductor and photonics technology used in AI data centres and 5G networks. As AI systems require huge computing power, demand for advanced optical technology has increased quickly. Investors believe Sivers could benefit strongly from this trend.
Although the company is still relatively small, its future business opportunities linked to AI have grown sharply. Investor confidence also increased after Sivers announced plans for a secondary listing on the Nasdaq stock exchange in New York.
Another major technology winner is French semiconductor materials company Soitec, whose shares have climbed 639%.
Even though the company recently reported weaker earnings due to lower demand in mobile phones and the automotive sector, investors are focusing on its role in the AI supply chain. Soitec produces special silicon materials used in AI data centres, smartphones and automotive radar systems.
The company is considered a leader in silicon-on-insulator technology, which may become essential for next-generation AI infrastructure.
Hydrogen and Fuel Cell Stocks Rise Again
Hydrogen and fuel-cell companies have also attracted investors this year.
British company Ceres Power has seen its shares rise 237%. The company develops fuel-cell technology that can produce cleaner electricity. Investors became more interested in alternative energy systems for AI data centres after US company Bloom Energy signed a major deal with Oracle.
Another UK company, ITM Power, has gained 173% in 2026. ITM produces electrolysers used to make green hydrogen.
The company benefited from improving revenues, stronger profitability and a partnership with German defence company Rheinmetall on synthetic fuel projects connected to NATO supply chains.
Investors are also excited about ITM’s future production plans, including a new manufacturing line expected to increase capacity significantly by 2028.
Healthcare Stocks Gain from Drug Demand
Healthcare companies have also performed strongly.
French biotechnology company Nanobiotix has climbed 89% this year after progress in a late-stage cancer treatment trial improved investor confidence.
The company is working with Johnson & Johnson on cancer therapies. A recent decision by the US Food and Drug Administration (FDA) to change part of the trial process may help speed up future milestone payments to the company.
Swiss company PolyPeptide has also gained 51% due to rising demand for obesity and diabetes drugs.
The company produces ingredients used in popular GLP-1 weight-loss medicines. As global demand for these drugs continues to grow, pharmaceutical companies are increasing production capacity, helping suppliers like PolyPeptide grow revenues and profits.
Satellite and AI-Related Communication Companies Grow
French satellite operator Eutelsat has become one of the biggest geopolitical winners of 2026. Its shares are up 64%.
European governments are increasingly looking for alternatives to Elon Musk’s Starlink satellite network because of concerns over technology independence and communication security.
Eutelsat’s OneWeb satellite network has gained attention from European policymakers, especially during ongoing geopolitical tensions.
Another unexpected success story is Trustpilot Group, based in Copenhagen and listed in London. Its shares have risen 57% this year.
Trustpilot benefited from the growth of generative AI. AI chatbots use large amounts of human-written reviews to answer customer questions, and Trustpilot’s database of more than 330 million reviews has become an important source of information.
The company also reported strong profit growth in 2025, further improving investor confidence.
Oil, Shipping and Tourism Benefit from Middle East Tensions
The conflict around the Strait of Hormuz has had a major effect on global markets in 2026.
Nigerian oil producer Seplat Energy, listed in London and Lagos, has gained 97% this year due to higher oil prices.
At the same time, Luxembourg-based tanker company d’Amico International Shipping has climbed 84%. Shipping disruptions forced vessels to take longer routes, increasing transport costs and boosting profits for tanker operators.
Spain’s largest hotel group, Meliá Hotels, has also benefited from geopolitical changes. Its shares are up 43% as more travellers choose Mediterranean destinations like Spain instead of some Middle Eastern countries.
The company reported strong summer booking growth for both luxury resorts and city hotels.
Financial Companies Recover Strongly
Croatia’s largest insurance company, Croatia Osiguranje, has seen its share price rise 62% this year.
The company has benefited from growing investor interest in Croatia after the country adopted the euro currency and joined the Schengen travel area.
UK company Saga has also performed well, with shares rising 54%.
Saga focuses on customers over 50 years old and sells cruises, travel packages, insurance and financial services. Stronger profits, lower debt and growth in its cruise business helped improve investor confidence.
Renewable Energy and Infrastructure Continue Growing
Companies connected to renewable energy and electrification are also attracting investors.
Romanian energy infrastructure company Premier Energy has doubled in value this year. The company is expanding renewable energy and battery storage projects across southeastern Europe.
In May 2026, Premier Energy started construction on one of the region’s largest battery storage systems in Romania.
Spanish company Cox ABG Group has gained 53% after announcing a major acquisition of Iberdrola’s renewable energy business in Mexico.
The company operates in water treatment, desalination and renewable energy across several international markets.
Steel and Copper Companies Benefit from AI Demand
Industrial materials companies are also seeing strong gains.
German steel distributor Klöckner & Co has risen 55% this year. Investors reacted positively after a takeover offer from US-based Worthington Steel increased speculation about future shareholder gains.
Meanwhile, German copper producer Aurubis has climbed 50%.
Copper demand has remained strong because of AI data centres, renewable energy projects and electrification. Higher copper prices and increased sales of sulphuric acid, a by-product of copper production, also supported profits.
Food, Drink and Real Estate Stocks Rise
Belgian drinks company Spadel has gained 46% this year after reporting strong sales growth. The company benefited from consumers choosing healthier drinks over alcohol and sugary beverages.
M.P. Evans Group, which operates palm oil plantations in Indonesia, also rose 46% thanks to high palm oil prices and record profits.
In real estate, Spanish company Emperador Properties gained 45% as investors became more optimistic about the recovery of Spain’s office property market.
Shopping centre owner Castellana Properties also performed strongly after reporting record visitor numbers in Spain and Portugal.
Three Major Themes Driving Europe’s Market Winners
Three main trends explain many of Europe’s best-performing stocks in 2026.
The first is artificial intelligence. Investors are not only buying AI software companies but also businesses supplying the infrastructure needed for AI, including semiconductors, photonics, copper, energy systems and data connectivity.
The second is geopolitics. Middle East tensions have affected oil prices, shipping routes and tourism patterns, creating both winners and losers across different sectors.
The third is corporate activity. Takeovers, acquisitions and restructuring plans have boosted investor confidence in several companies, even when their financial performance has not yet fully improved.
Overall, Europe’s stock market in 2026 shows how rapidly changing technology, energy demand and global politics are reshaping investor priorities across industries.
