In the context of the transition of the Russian agri-food system to the Agri-Food 4.0 model, digital tools are becoming a critical element of pricing and logistics mechanisms in the grain market. The purpose of this study is to comprehensively assess the impact of digital technologies on the formation of domestic and export prices, as well as on the spatial redistribution of grain in Russia. The methodological base includes an analysis of public services of the FGIS "Grain", a panel regression model of price factors and an expert survey of industry representatives. The results confirm that the introduction of an end-to-end batch tracking system, electronic platforms and predictive analytics algorithms allows for increased price transparency, a reduction in transaction costs by up to 12%, and a transaction time of up to 48 hours. Regional imbalances were identified: up to 27% of the harvest of southern regions is exported to the domestic market in the absence of effective e-logistics channels. The author proposed the concept of a "digital damper" that smooths out price volatility by automatically connecting hedging instruments to the FOB-Novorossiysk stock index. It was found that the main risks remain the digital inequality of small agribusiness entities, institutional fragmentation of information systems and cyber threats. Prospects for further development are associated with the integration of AI modules for forecasting yields and the ecological footprint of products into a single supply chain management platform.
