The Most Important AI Conferences in Europe 2026: Festivals, Summits and Data Events

d:u – data:unplugged (Berlin & Münster, Germany)

What started three years ago as a data and AI festival in Münster is today Europe's biggest movement for data, AI and digital transformation. In 2026, the annual d:u Festival gets its first-ever satellite: the d:u Deep Dive Berlin. Both formats share the same mindset: practice over theory, conversation on equal terms and concrete impulses companies can act on — and for international visitors, a firsthand look at how German companies are approaching the data and AI transformation.

d:u Deep Dive Berlin – June 11, 2026

The first d:u satellite touches down at Kraftwerk Berlin. Under the guiding theme "AI meets Business," around 1,500 decision-makers, experts and data and AI leads come together. The format is deliberately focused: three stages, 50 speakers, four masterclasses, twelve round tables, 15 guided tours, experience corners, 40 partners and a special act in the evening. The Deep Dive goes a step deeper than the festival — more compact, more intensive, more concrete and built consistently around maximum exchange.

Four focus areas take centre stage:

• AI use cases in the enterprise: concrete, real-world examples of how AI delivers measurable value today.
• Agentic AI in the enterprise: the technologies, methods and use cases around AI agents, foundation models and new automation logic.
• From data to AI: the data architectures, platforms and structures that power high-performing, scalable AI solutions.
• Scaling AI: the path from a first pilot to enterprise-wide AI adoption.

The d:u Deep Dive is built for CIOs, CDOs, CTOs and CFOs, for AI leads, developers, heads of finance and controlling, data and analytics leads, enterprise architects and data platform owners — and for everyone who carries responsibility for data. If you're looking for concrete answers, in-depth discussion and fresh approaches for your own data and AI projects, Berlin is the place to be. Secure your ticket for the d:u Deep Dive Berlin and spend a day deep in the business reality of AI — you'll find all the details on the Deep Dive programme page.

d:u27 Festival – April 13 & 14, 2027 (Münster)

In 2027, the big d:u Festival returns to Münster. On April 13 and 14, the city once again becomes the meeting point for Europe's data and AI community — from SMEs and family businesses to start-ups, tech corporations, politics and society. The festival stays true to its principle: real substance and a genuine festival experience, practice over theory and conversation on equal terms. Around 17.000 AI experts, decision-makers and innovators are expected. Secure your d:u27 ticket early and bring your team to Münster.

World AI Cannes Festival (Cannes, France)

On February 12–13, 2026, the World AI Cannes Festival kicks off the European AI conference season in style. Held at the iconic Palais des Festivals – yes, where the film festival happens – WAICF positions itself as the "#1 AI event for business and society."

With over 10,000 participants, 320 international speakers, and 220 exhibitors expected, the scale is impressive. The programme spans four main tracks: AI in Business, AI Governance, Next-Gen AI Technology, and Health AI. Keynote speakers include tech leaders and chief data officers from Meta, IBM, LinkedIn, and major European enterprises.

What makes Cannes distinctive is its dual focus on commercial application and societal impact. Sessions explore everything from scaling machine learning projects to navigating the EU AI Act and data governance – relevant for any organisation operating in Europe. The glamorous setting doesn't hurt either: if you need to convince your board that AI conferences are worth attending, the Côte d'Azur backdrop helps make the case.

The AI Summit London (London, UK)

On June 10–11, 2026, The AI Summit London celebrates its tenth year and has established itself as the flagship enterprise AI conference in Europe. The tagline says it all: "Where commercial AI comes to life."

Held at Tobacco Dock during London Tech Week, the summit brings together 4,500 technologists and business leaders from around the world. The programme features 300+ speakers across six stages, with a strong emphasis on real-world implementation. This isn't a research conference – it's where enterprises share how they're actually deploying AI systems and machine learning at scale.

Key themes include AI governance and ethics, scaling strategies, and sector-specific applications across finance, healthcare, manufacturing, and retail. The expo floor hosts 100+ exhibitors showcasing cutting-edge AI technologies, making it a practical venue for evaluating solutions. For decision-makers with concrete implementation questions, London delivers actionable insights.

AI & Big Data Expo Europe (Amsterdam, Netherlands)

On October 20–21, 2026, the AI & Big Data Expo takes a different approach: less conference, more trade show. The Amsterdam edition is part of a global series, and the format reflects that – a large exhibition floor combined with conference tracks.

For teams evaluating AI technologies and big data vendors, this is valuable. Over 150 companies showcase their solutions, from automation platforms to data infrastructure tools. Developers and data science teams can explore the latest in machine learning, generative AI, and analytics technology. The conference tracks cover practical topics: moving from prototypes to production, data governance, sector-specific deployments.

The vibe is more pragmatic than visionary. Attendees come to see demos, compare solutions, and make buying decisions. If your 2026 agenda includes selecting AI tools or big data platforms, Amsterdam should be on your radar. The event also offers hands-on workshops and technical deep-dives for teams ready to move beyond evaluation into implementation.

‍

World Summit AI (Amsterdam, Netherlands)

Also in Amsterdam, but a completely different beast: World Summit AI positions itself as the "epicentre of the global AI ecosystem." Where the Expo is about vendors, World Summit AI is about ideas and people.

The attendee mix is uniquely broad – data scientists, machine learning engineers, developers, CEOs, investors, policymakers, researchers. The summit has a reputation for big announcements; companies reportedly queue for years to launch products here. If you want to explore where artificial intelligence is heading globally, this is where the conversation happens.

For mid-market decision-makers, World Summit AI offers perspective on the future. The sessions cover deep learning, generative AI, computer vision, and AI ethics – skewing more technical and visionary than immediately practical, but the networking is unmatched. Where else can you grab coffee with a leading AI researcher and discuss your implementation challenges? Tech leaders, chief scientists, and industry titans share the same space as start-ups and developers.

Data Innovation Summit (Stockholm, Sweden)

On May 6–8, 2026, the Data Innovation Summit takes place – the Nordic region's flagship data conference that has grown into a world-class event. The 11th edition expands to three days for the first time, with 15 stages and 3,500+ attendees expected.

The programme balances technical depth with business value. Days one and two cover data engineering, machine learning operations, AI governance, data science, and analytics strategy. Day three is new: dedicated industry tracks for finance, manufacturing, healthcare, retail, and public sector – perfect for exploring how digital transformation plays out across different industries.

What makes Stockholm worth the trip is the community. The Nordic data and AI ecosystem has a reputation for pragmatism and openness – people share what actually works, not just what sounds impressive. The Data After Dark networking event and the new 10km DIS Run around Kungsholmen Island reflect the summit's approach: serious content, human connections. For developers, data scientists, and business leaders alike, it's a chance to explore cutting-edge research and practical applications in one place.

‍

FT Future of AI Summit (London, UK)

On November 4–5, 2026, the FT Future of AI Summit is designed for you if your job title includes "Chief" or "Head of." With 87% of attendees at decision-maker level, this is one of the most senior AI gatherings in the world.

The Financial Times curates the programme around strategic leadership challenges: scaling AI investments, navigating regulation and governance, workforce transformation for the AI revolution, measuring business value and ROI. Sessions feature executives who have led digital transformation initiatives – not vendors pitching solutions.

The intimate format (around 900 attendees) enables genuine networking and peer exchange. For C-level executives seeking candid conversations about what works in AI adoption, London in November offers that environment.

‍

CogX Festival (London, UK)

CogX defies easy categorisation. Part tech conference, part ideas festival, part cultural event – it's drawn comparisons to TED meets SXSW for artificial intelligence.

The scale is massive: previous years attracted tens of thousands of participants from around the world. The programming spans AI in business, climate change and sustainability technology, ethics, creative industries, and beyond. You might attend a session on enterprise AI strategy, then wander into a debate about AGI safety with leading researchers, then end up at a live performance.

For decision-makers, CogX offers a 360° view of the global AI ecosystem. It's a place to step outside your industry silo and explore how artificial intelligence intersects with society at large – from healthcare to finance to start-ups building the future. The networking is serendipitous – you never know which tech leaders or brightest minds you'll meet. If you can only attend one event that challenges your assumptions about AI's role in the world, CogX is it.

European Big Data Value Forum (Galway, Ireland)

On September 30 – October 1, 2026, the EBDVF is different from everything else on this list. Organised by the Big Data Value Association in collaboration with the European Commission, it's where EU policy meets industry practice.

Attendees include innovation managers, researchers, developers, and policymakers – many involved in EU-funded research projects. The programme covers European data strategy, AI governance, big data technologies, and cross-border collaboration.

For companies navigating the EU AI Act or exploring European funding opportunities, Galway provides direct access to the people shaping the rules and the future of technology policy. It's smaller and more specialised than commercial conferences, but strategically valuable for anyone doing business in Europe.
