Abstract <p>This article analyzes action coordination methods that are formed in the digital economy and used by market players. It is shown how price cycles change under the influence of digital cartels. The new cartelization forms include algorithmic pricing, reliance on conscious parallelism of digital platforms, and hidden specialist agreements. A host of special digital economy tools, such as aggregate data analysis in specialized programs, machine-learning aimed at identifying monopolistic trends in the market, and using nonregulated digital contacts of third parties, help maintain cartel discipline in the sector even without formal negotiations and clandestine agreements.</p>
