‘Collapse’ is one of the terms used to describe world ending or transforming events and processes. Notions of apocalypse and existential risk can also constitute stories about radical large-scale changes, such as those envisioned through climate change. Occasionally used interchangeably, each of these terms—‘apocalypse’, ‘collapse’, and ‘existential risk’—is etymologically distinct and conceptually divergent and each constructs meaning and affect is different ways. In this chapter, I offer a novel conceptualisation of collapse—one that accounts for diverse and dynamic geographies of lived experience. I begin by interrogating the notion of existential risk, particularly elitist articulations associated with a philanthropic venture known as Effective Altruism and with longtermism. Using insurance as my empiric, I plot pervasive and powerful intersections between schemes to address existential risks and how risk is mobilised in insurance discourses and practices. I then consider Judeo-Christian ideas about apocalypse, revealing how they are apparent in imaginaries of a calamitous uninsurable future. I conclude by arguing that, although distinct, existential risk and apocalyptic framings both negate real-time inequality and inequity. Collapse, on the other hand, is an end-of-the-world framing receptive to uneven variegated worlds and the lived experiences of people and places.
