AI Events Calendar

A continuously updated, chronological timeline of every major AI event worth a place in your diary, from CES and MWC Barcelona to NVIDIA GTC, VivaTech, AI Summit Barcelona and NeurIPS. Each entry lists the exact dates, host city and event type, so you can plan your AI events year at a glance.

Methodology

How we maintain this calendar

A calendar is only as good as its sourcing, so here is exactly how this one is kept honest:

• Where the dates come from — organiser announcements and official press releases, not aggregated guesswork.
• How often we update — we review the full list quarterly, and sooner when a major organiser shifts a date.
• The "to be confirmed" rule — any date we cannot verify against an official source is labelled to be confirmed rather than presented as fixed.
• What makes the cut — we include events with genuine scale or AI relevance and leave off minor or one-off gatherings; that inclusion call is a judgement, not a threshold a bot applies.

This calendar is curated and signed by Guillaume Rostand, Tanguy Wincker and Adam Hruska. The arbitration of what belongs here is editorial — real people deciding, then verifying — not a scraper dumping every listing it finds.

The full AI events calendar

The table below lists the major AI events in chronological order and is updated as dates are confirmed. It mixes dedicated AI summits, large technology shows with a heavy AI focus, and the leading academic machine-learning conferences across cities such as Las Vegas, Barcelona, London, Paris, Berlin and Lisbon. Dates marked to be confirmed had not been officially fixed at the time of the last update.

Major AI events, sorted chronologically and kept up to date. Always check the official event website before booking travel.

Q3 (July–September): summits and applied AI

The summer and early autumn balance academic milestones with large applied-AI gatherings, building towards AI Summit Barcelona.

Q4 (October–December): the year closes in Europe and beyond

The final quarter is unusually dense, mixing Europe's largest tech festivals with the year's biggest research conference.

• AI Expo Europe (Amsterdam, 20–21 October) brings enterprise AI buyers and vendors together.
• Web Summit Lisbon (9–12 November) is the largest tech event in Europe, with AI front and centre.
