A sample of 367 residents was used.Within the hallmark event context, findings reveal that coopetition enables strategic alignment among stakeholders, fostering value creation that would not be possible individually. Although coopetition does not directly generate social value, its influence emerges when mediated by the development of hallmark events, which can be an accelerator of benefits for communities and destinations.Results demonstrate that the distinctive and often conflicting attributes of hallmark events demand governance that goes beyond conventional planning models. Coopetition thus emerges as the most appropriate management framework, balancing collaboration and competition, coordinating diverse actors, and ensuring long-term social and economic value for host communities.The analysis explores the social value creation from hallmark events using an outstanding Latin American. The study highlights that hallmark events enhance destination competitiveness through a society-centred approach, where resident participation is essential to strengthen well-being, local identity and sustainable practices.
