Every fall, thousands of researchers, founders and investors plan their travel around the same question: which AI conferences 2026 are actually worth the trip? The answer is a short list. A handful of gatherings in San Francisco, New York, Amsterdam, Lisbon and Sydney now set the agenda for the artificial intelligence industry, from research breakthroughs to enterprise deals. This guide rounds up the events that defined the 2026 calendar, with verified dates, venues and formats, so you can decide which rooms you need to be in.
What Are the Best AI Conferences 2026?
The 2026 calendar split into two halves. Spring and summer belonged to enterprise flagships: HumanX drew 6,500 enterprise leaders to the Moscone Center in San Francisco in April, and the Data + AI Summit filled San Francisco again in June with a heavy agentic AI program. The fall is the busiest stretch, with seven major events still to come between October and December. Several of these conferences anchor wider city tech week seasons, the city based format our What Is Tech Week pillar explains in detail.
Here is the rest of the 2026 calendar at a glance:
| Event | Dates | City | Best for |
|---|---|---|---|
| World Summit AI | Oct 7 to 8 | Amsterdam | Enterprise and policy leaders |
| TechCrunch Disrupt | Oct 13 to 15 | San Francisco | Founders and investors |
| ODSC AI West | Oct 27 to 29 | Burlingame | Practitioners and data teams |
| Web Summit | Nov 9 to 12 | Lisbon | Global tech and startups |
| ODSC AI NYC | Dec 2 to 3 | New York | AI practitioners |
| NeurIPS | Dec 6 to 12 | Sydney | Researchers |
| The AI Summit New York | Dec 9 to 10 | New York | Enterprise buyers |
AI Conferences in San Francisco in 2026
San Francisco hosted more AI gatherings in 2026 than any other city, which surprises nobody. Fresh off the calendar, The AI Conference ran September 30 to October 1 at Pier 48 in Mission Rock, with a workshop day on September 29. The vendor neutral event drew more than 5,500 builders, researchers and leaders across five tracks and more than 120 speakers, and its Startup Showdown put emerging AI companies on stage in front of investors. It was created by the team behind MLconf and Ben Lorica, the former program chair of the O’Reilly Artificial Intelligence Conference, and it sits inside a wider SF AI Week with events like Party in the Park and Ignite Talks.
Still to come, TechCrunch Disrupt takes over Moscone West from October 13 to 15. Disrupt is a startup and venture conference first, but AI now runs through most of its programming, including the Startup Battlefield pitch competition and a dedicated Real World AI stage covering robotics and physical AI. Later in the month, ODSC AI West runs October 27 to 29 at the Hyatt Regency near San Francisco airport in Burlingame. The three day format leans toward hands on workshops over keynote theater, with tracks on agentic AI, large language models and retrieval, AI engineering and MLOps.
Earlier in the year, HumanX brought 6,500 enterprise leaders, builders and investors to the Moscone Center from April 6 to 9, and the Data + AI Summit ran June 15 to 18 with a program centered on agentic AI. San Francisco also hosts a broader startup gathering each year, covered in our SF Tech Week guide.
AI Conferences in New York in 2026
New York closes out the year with two very different AI events in December. The AI Summit New York runs December 9 to 10 at the Javits Center. Now in its eleventh year and run by Informa, it is the largest commercial AI event in the city, with ten content stages, roughly 5,000 attendees and a program built around enterprise case studies rather than research.
A week earlier, ODSC AI NYC runs December 2 to 3 at the Jay Conference Center in Bryant Park. Billed as the AI for Work Summit, the two day event is built entirely around turning AI pilots into production workflows, with sessions on AI agents and copilots in production, evaluation methods and governance. If the Javits event is for executives comparing vendors, the Bryant Park event is for practitioners who need to ship. New York’s wider startup calendar is covered in our NYC Tech Week guide.
AI Conferences Across Europe in 2026
Amsterdam is having a moment. World Summit AI returns to the Taets Art and Event Park from October 7 to 8 for its tenth anniversary edition, built around the theme Guardians of Tomorrow. The program runs across ten tracks with more than 300 speakers drawn from enterprise AI teams, frontier labs, startups, investors and researchers, and it is the largest general AI conference in Europe.
The city also hosted the European debut of HumanX from September 22 to 24 at the RAI Amsterdam. The three day event drew more than 2,500 senior AI practitioners, investors and policymakers alongside more than 200 speakers and more than 150 sponsors. HumanX was built by the team behind Money20/20, Shoptalk and HLTH, which explains the heavy enterprise buyer presence in the room.
London’s The AI Summit London ran June 10 to 11, focused on enterprise AI adoption across industries. And Web Summit takes over the Altice Arena in Lisbon from November 9 to 12, with organizers projecting roughly 70,000 attendees. AI is now one of the event’s largest content tracks, which makes Web Summit the best single stop for reading where global tech investment is heading.
More 2026 AI Events Around the World
The AI conferences 2026 calendar stretched well beyond the usual hubs. AI Con USA ran June 7 to 12 in Seattle with an applied AI and machine learning program; the city’s startup scene is covered in our Seattle Tech Week guide. In Las Vegas, Ai4 ran August 4 to 6 at The Venetian with around 1,000 speakers and 12,000 attendees across industries. The AI Infra Summit ran September 15 to 17 in Santa Clara, rebranded from the AI Hardware and Edge AI Summit, with a program built around AI data centers, data and models.
Singapore hosted SuperAI on June 10 and 11 at Marina Bay Sands, drawing roughly 5,000 attendees. And the research calendar peaks in December, when NeurIPS holds its 40th edition in Sydney from December 6 to 12, the first time the main venue has moved to Australia, with satellite programming in Atlanta and Paris from December 9 to 13. Registration has historically been lottery based, so plan early.
How to Choose the Right AI Conference for Your Goals
Pick by outcome, not by brand. If you track research and publications, NeurIPS in Sydney is the one that matters, with the AAAI conference already announced for February 16 to 23, 2027 in Montreal. If you need hands on skills for a working data or AI team, the ODSC events and the Data + AI Summit are built for practitioners. Most AI conferences 2026 opened registration months in advance, so the earlier you commit, the better the pricing.
Enterprise buyers comparing vendors get the most from The AI Summit New York, The AI Summit London, HumanX and World Summit AI, where the programs center on deployment case studies. Founders and investors should default to TechCrunch Disrupt and its Startup Battlefield, The AI Conference and its Startup Showdown, or Web Summit, where the investor to founder ratio is the whole point. And if your world is GPUs and data centers, the AI Infra Summit is the specialist pick, with NVIDIA’s GTC already announced for March 14 to 18, 2027 in San Jose.
Frequently Asked Questions
What is the biggest AI conference in 2026?
By overall attendance, Web Summit in Lisbon is the largest, with organizers projecting roughly 70,000 attendees across the full event, though AI is one track among several. Among conferences built specifically around AI research, NeurIPS is the largest, holding its 40th edition in Sydney in December 2026.
Are there any AI conferences 2026 still left to attend this year?
Yes. As of early October, seven major events remain: World Summit AI in Amsterdam (October 7 to 8), TechCrunch Disrupt in San Francisco (October 13 to 15), ODSC AI West in Burlingame (October 27 to 29), Web Summit in Lisbon (November 9 to 12), ODSC AI NYC (December 2 to 3), NeurIPS in Sydney (December 6 to 12) and The AI Summit New York (December 9 to 10).
Which AI conference is best for startup founders?
TechCrunch Disrupt is the strongest pick, thanks to the Startup Battlefield pitch competition and a room full of early stage investors and press. The AI Conference in San Francisco runs its own Startup Showdown for emerging AI companies, and Web Summit in Lisbon offers unmatched investor density for founders who can make the trip.
How far in advance should I register for an AI conference?
Three to six months is the safe window. Early bird pricing usually disappears well before the event, popular workshops sell out, and research conferences like NeurIPS have historically used lottery based registration, which rewards early planning.
