This chapter surveys portrayals of money within US speculative fiction. While they may take us to alien planets or alternate universes, such works also serve to remind us how strange “ordinary” money already is. Speculative fiction has often sought to reimagine money in some more rational or explainable form. These thought experiments often propose money based on some purportedly stable and incontrovertible value, such as labor, time, energy, or motion. There is a second and somewhat distinct tendency, which envisions reputation-based currencies and other “storied moneys,” often capable of reflecting diverse incommensurable values. Then there are portrayals of large fortunes that, whether or not they come with overt speculative elements such as magic or futuristic technologies, can also take on an aura of the fantastic. In particular, large fortunes become storied money to the extent that they reflect and enact their owners’ personal characteristics, relationships, and histories. Speculative fiction also often blurs with speculative practices, from Josiah Warren’s Time Store in the 1820s to the Technocracy movement of the 1930s to contemporary cryptocurrency, Non-Fungible Tokens, and blockchain finance. This porous boundary invites the question: might money itself be understood as a kind of speculative fiction?
