Devcon IX Lisbon 2027

Devcon IX is the next edition of Devcon, the yearly developer conference organised by the Ethereum Foundation, and it follows Devcon 8. It is scheduled for 11 to 13 October 2027 in Lisbon, Portugal, with CCL – Lisbon Congress Centre as the venue. The event changes country every year: the previous edition, Devcon 8, was held at Jio World Centre in Mumbai, India, on 3 to 6 November 2026. The audience is developers and researchers first. The organiser positions Devcon as a gathering for people who build open-source, decentralised systems on Ethereum, together with privacy advocates and the communities that form around those projects. Its stated principles are censorship resistance, open source, privacy and security, and the Foundation says it deliberately goes to places where communities are growing rather than only to established hubs. By the organiser's own count, Devcon has run 13 editions since 2014, drawn more than 60,000 attendees in total and published over 1,100 session videos in its public archive. The Lisbon programme format has not been announced. Past editions have been built around talks and keynotes: every Devcon 8 session was recorded and published in the Devcon Archive. Community members can submit Devcon Improvement Proposals, known as DIPs, a public process for suggesting changes to how the conference itself is run. Tracks, schedule and speakers for Lisbon are still open. The names currently shown on devcon.org, including Vitalik Buterin, Audrey Tang and Justin Drake, belong to the Mumbai edition and should not be read as a 2027 line-up. Tickets are not on sale. The Lisbon page offers only a waitlist for now, and no prices, tiers or sales dates have been published. The street address of the venue is not listed either. This page will be updated once sales open. For affiliates and media buyers the fit is narrow. Devcon is not a marketing or acquisition show: there is no affiliate track, nothing in the published material points to an exhibition or deal-making floor, and the crowd is protocol engineers rather than operators with budgets. It is still worth watching for crypto affiliates who promote wallets, exchanges or on-chain products, because the teams shipping those products and the Foundation researchers who shape the roadmap spend three days in one building. Treat it as a way to see what is coming next in the Ethereum ecosystem, not as a place to sign partnership deals.
