Lisbon’s Web Summit cancelled its entire programme for Wednesday 11 November 2026 at the request of the Portuguese government, as Storm Charles hit the country. For the thousands of start-ups and investors who came for three days of meetings, a third of the schedule has vanished. The organisers moved some sessions to the final day, without announcing any compensation at the time the media outlets consulted were writing.
A decision taken by the Portuguese state
The cancellation did not come from the organisers alone. On Tuesday 10 November, the Portuguese government officially informed them that the second day should not go ahead, Euronews reports. Three risks were cited: tidal flooding, severe disruption to public transport and gusts threatening outdoor structures. The decision was reached after consulting the civil protection authority (ANEPC) and the police (PSP). The announcement came on Tuesday 10 November according to Euronews, the Irish Times and The Next Web; only The Stack places it on the evening before.
Lisbon’s mayor, Carlos Moedas, had himself argued for a cancellation, while leaving the final say to the government and the organisers. According to the Irish Times, the Prime Minister had recommended suspending the day’s events, as the south of the country, Lisbon included, was under a red weather warning.
The situation went well beyond the conference. According to The Next Web, mainland Portugal was placed under a state of alert for the Wednesday, with schools and non-essential public services kept closed; the city shut tunnels, parks, gardens and cultural venues from midnight, according to The Portugal News as cited by the site, and the IPMA weather institute forecast gusts of up to 120 km/h.
What start-ups and investors lose
Web Summit is first and foremost a meeting machine. Euronews mentions nearly 70,000 expected attendees, 900 speakers and more than 2,000 start-ups. The Stack puts the figure at 3,000 exhibiting companies and a record 1,943 investors. For a young company, a cancelled day means meetings scheduled long in advance that have to be rearranged, often in a hurry. FrenchWeb points out that a full day of meetings remains to be rescheduled for exhibitors, investors and sales teams.
The cost of attending makes the loss more painful. The Irish Times notes that a standard ticket cost €1,595, a VIP ticket up to €1,950 and the “chairperson” pass €25,000. For a three-day event, the cancelled day therefore represents a significant share of what each attendee paid, not counting accommodation and travel. The Next Web says the ticket holders affected were to be contacted directly; FrenchWeb notes that no compensation scheme had been announced.
A packed Thursday and online meetings
On Wednesday 11 November, shortly after 11:30, attendees received an email announcing that Web Summit would return the following day, according to the Irish Times. The organisers promised the busiest Thursday in the event’s history, with more speakers and meetings than ever, as a large share of Wednesday’s sessions had been moved there. Chief executive Paddy Cosgrave wrote on an internal messaging channel that the production team had worked through the night, until 3 a.m., to make the venue safe.
Meanwhile, the ecosystem improvised. FrenchWeb lists a virtual “Storm Summit” organised by Founderlink in three sessions, a “Win(d) Summit” offered by Ulmero.ai and several online events maintained by Portugal Tech Week. Portuguese media outlets Jornal de Negócios and Sábado even nicknamed the event the “Wet Summit” after water leaked into the halls of the Feira Internacional de Lisboa, again according to FrenchWeb.
The limits of what we know
Several points remain unclear. The articles consulted were published before or during the cancelled day: they do not show whether Thursday lived up to its promises or how many meetings were made up. Actual attendance also differs from forecasts: Lisbon’s mayor spoke of more than 60,000 people on site during the week, according to The Next Web. Finally, the media do not agree on the emergency regime declared: Euronews speaks of a state of emergency, while The Next Web, the Irish Times and FrenchWeb refer to a state of alert.
The episode is a reminder of a concrete weakness of large in-person trade shows: everything rests on a few days, in a single venue, exposed to unforeseen events. For start-ups that concentrate a share of their annual prospecting there, the safeguard lies in meetings confirmed in advance and a video-call fallback.
