A Bitcoin Policy Institute investigation into how the Party for Socialism and Liberation (PSL), the political arm of the Shanghai-based Marxist Neville Roy Singham, has become a recurring force in the nationwide campaign against American AI data centers. Drawing on 19 case studies across 21 campaigns in 14 states, the report documents how PSL chapters have organized door-knocking drives, petitions, rallies, and packed council chambers in efforts that delayed, scaled back, or blocked roughly $23.6 billion in proposed AI infrastructure, contributing to 10 moratoria, 1 permanent ban, and 4 scrapped projects. It traces the overlapping leadership between PSL and Singham-funded nonprofits with documented CCP ties, examines the party's opaque and undisclosed general funding, and argues that authentic local opposition to data centers can be amplified and redirected by foreign-aligned actors. The central call is for full transparency into who finances these consequential campaigns shaping America's AI buildout.
