Until recently, MDPI and Frontiers were known for their meteoric rise. At one point, powered by the Guest Editor model, the two publishers combined for about 500,000 papers (annualized), which translated into nearly USD $1,000,000,000 annual revenue. Their growth was extraordinary, but so has been their contraction. MDPI has declined by 27% and Frontiers by 36% in comparison to their peak.
