Lisbon Underground Afterparty takes place on September 29, 2026 in Lisbon from 9 pm to 2 am — the evening after day one of SBC Summit. It is organized by SpinBetter Partners and SLYSE for partners, affiliates and iGaming industry people in town for the summit.
Format
Unlike the official Opening Party, this is an informal night built around rap and hip-hop: DJ set, open bar, beer pong and a gaming zone. The main intrigue is a live performance by a secret rap headliner whose name the organizers keep under wraps until the event.
How to get in
The event is invite-only, for partners and affiliates. No tickets are sold — you register on the event page in advance and the organizers confirm attendance.
Who should go
Media buyers and teams attending SBC Summit who want to meet SpinBetter managers and other networks in a relaxed setting rather than at a booth. If you are also planning the Opening Party, note they are on the same night — pick one or make both.
