The tension between connective action and platformisation: Disconnected action in the GameStop short squeeze

Although the Reddit-led short squeeze of GameStop shares in 2021 drew comparisons with Occupy Wall Street, this article focuses on one key area of difference: where Occupy exemplified the theoretical model of connective action through its discursive and technological openness, mobilisation around the short squeeze followed a different pattern characterised by discursive and technological disconnections, which we argue partly reflects the intervening decade of platformisation. Our case shows how platforms can establish boundaries as well as brokerage points in contentious politics, with particular regard to repertoires of action, collective identities and discourses. We show how in our case, these boundaries impeded discursive and technological connections, instead organising users into relatively disconnected zones and ultimately reducing their power and impact over broader discursive systems. Our argument is explored using three data sets from Reddit, Twitter and legacy news media outlets, using a combination of non-negative matrix factorisation (NMF) topic modelling and manual content analysis.
