The assetization of essential goods brings to high-income countries the logics of scarcity that have been dominant for long in low-to-middle income countries—fostering the rise of new forms of activism. Will this new activism strengthen already existing social movements or weaken them through more moderate politics? Building on interviews and the observation and mapping of activist events, we investigate this question through the case of pharmaceuticals. We detail how the assetization of pharmaceutical drugs has triggered the constitution of a new ‘flank’ in the access to medicines (A2M) movement—pharmaceutical transparency activism. We argue that transparency activism has expanded the contestation of the pharmaceutical state of affairs, by bringing into the broader A2M movement countries that were previously at the core of global pharmaceutical chains. Our article illuminates how the assetization of essential goods creates forms of activism that have significant impact on existing social movements.
