Abstract
It is widely believed that information spread on social media is a percolation process, with parallels to phase transitions in theoretical physics. However, evidence for this hypothesis is limited, as phase transitions have not been directly observed in any social media. Here, through an analysis of 100 million Weibo and 40 million Twitter users, we identify percolation-like spread and find that it happens more readily than current theoretical models would predict. The lower percolation threshold can be explained by the existence of positive feedback in the coevolution between network structure and user activity level, such that more-active users gain more followers. Moreover, this coevolution induces an extreme imbalance in users’ influence. Our findings indicate that the ability of information to spread across social networks is higher than expected, with implications for many information-spread problems.

Extended data
Extended Data Fig. 1 Relative error of estimated retweet probability \(\frac{{\hat \beta - \beta }}{\beta }\) as a function of cascade size P∞.
Each dot represents one simulation of data-driven model M2 in Weibo network 2014. \(\hat \beta\) represents the estimated retweet probability by \(\hat \beta = \frac{{P_\infty }}{{P_e}}\) and the real retweet probability is β=0.001 for all dots. Both axis are plotted in log scale.
Extended Data Fig. 2 Global state and localized state of information spreading.
a, Schematic of information cascade in directed network. The spreading in undirected network is a specific scenario in which PGIN(β)=PGOUT(β)=PGSCC(β). b, The cascade sizes are obtained from simulations using data-driven percolation model in Weibo network. The x-axis is plotted in log scale. Each blue point represents one realization. The box region with dashed purple line is most useful for observing phase transitions.
Extended Data Fig. 3 Cascade size distribution ps of uniform models in Weibo.
a-c, The cascade size distribution ps with different retweet probabilities β or λ. The red crosses and yellow circles represent simulation results. The theoretical results are numerical solutions with quadruple-precision floating-point format. d, The probability of large cascade size fluctuation below the percolation threshold. The values of probability that P∞ happens in the boxes are theoretical results. Each blue dot represents a real cascade. βc=2.64×10−3 is the percolation threshold of uniform site percolation, which equals to the threshold of bond model. We use log scale for both axis in A-C, and set only x-axis as log scale in D.
