Neoliberalism initially invoked the authority of competitive markets as the ideal epistemic mechanism for socio-economic coordination. Yet, the rise of neoliberal ‘market society’ in Western advanced economies since the 1970s has been underpinned by a normative political theory that advocates the reconfiguration of society and politics around the authority of economic theory and knowledge in both production, but especially finance. Conversely, the reform-era development of China’s ‘socialist market economy’ has been underpinned by an insistence on retaining centralized political power over the allocation of financial capital. This article argues that the rise of digital algorithmic technologies constitutes one means by which these contrasting politico-economic visions are being more closely reconciled. It investigates the ways in which China’s ongoing construction of an explicitly authoritarian capitalism is being facilitated by the deployment of complementary financial technologies that enable the Chinese Communist Party to embrace the micro-level epistemic coordinative function of markets without relinquishing macro-level political power and juridical sovereignty over these markets. Following a comparative historiography of the praxis of ‘neoliberal’ and ‘neostatist’ political theory in contemporary capitalism, two case studies of blockchain-enabled currency and big-data driven credit scoring in China illustrate the emergent Fintech foundations of Chinese authoritarian capitalism. The findings contribute to our understanding of how markets are being reshaped by new algorithmic technologies, as well as illuminate some of ideological contradictions in existing conceptions of markets as (neo)liberal institutions at the centre of capitalist political economy.
