Web Summit Lisbon 2025 opened on November 10, 2025, kicking off four days of talks and dealmaking that run through November 13, 2025. The conference’s Opening Night took place at the MEO Arena in Lisbon, with the program and schedule hosted on Web Summit’s official platforms and corroborated by the EIT events portal.
Big crowd, familiar venues
Organizers expect more than 70,000 attendees and 800-plus speakers across 20 tracks. Those headline figures appear in official and semi-official listings and are echoed by the EU-backed EIT. The event is staged at the MEO Arena and the FIL exhibition complex in Parque das Nações, a venue pairing flagged across the organizer’s materials and external partner calendars.
Opening Night speakers and themes
The curtain-raiser featured a cross-section of culture and corporate leaders. Maria Sharapova and Khaby Lame joined executives including Sarah Meron of IBM and Mark Nelsen of Visa, alongside Lisbon Mayor Carlos Moedas and Gonçalo Matias, a minister in Portugal’s cabinet. Those names are listed on the organizer’s Opening Night page and were reported by entertainment trade press covering the show. The week’s agenda spans 20 content tracks, including AI, fintech, marketing and sustainability, per the organizer’s overview and live schedule.
Airport capacity strains spill into the spotlight
This year’s opening also revived Lisbon’s long-running airport capacity debate. A surge in private aviation around the conference forced Lisbon’s Humberto Delgado Airport to turn away some private jets, with diversions reported to Badajoz, Spain.
Portuguese authorities have acknowledged Lisbon airport’s structural constraints and are advancing both short-term expansion works and a new-airport plan. Government communications note operational constraints at Humberto Delgado, while recent updates describe capacity-boosting works and the AHD expansion plan submitted by ANA, the airport operator. Local business media have also reported the ANA plan to raise declared capacity, framed as a bridge to a future greenfield site.
Why it matters
Web Summit is one of Europe’s largest tech gatherings by headcount and media reach. The combination of 70,000-plus delegates and 20 content tracks makes Lisbon a focal point for startup launches, corporate product news and public policy remarks that can ripple across European tech. The conference’s official materials and allied listings underscore that scale, while the airport episode underscores Lisbon’s infrastructure pinch point as the city hosts mega-events.
